The Use of Brown's Double Exponential Smoothing Method to Predict Harvest Yields in Horticultural Crops

Agriculture stands as a pivotal sub-sector within the economy of North Aceh. Among its primary commodities are horticultural crops, encompassing the cultivation of vegetables, fruits, medicinal plants, and ornamental flora. In endeavors to boost agricultural productivity and efficiency, the utilization of harvest prediction methodologies has grown increasingly indispensable. This study relies on historical harvest data spanning from 2017 to 2022 to forecast crops such as leafy greens, fruits, and medicinal plants. The selected plants for prediction include spinach, water spinach, cucumber, banana, durian, rambutan, ginger, lesser galangal, and turmeric. Data analysis employs Brown's double exponential smoothing method, selecting the α (alpha) parameter that minimizes the Mean Absolute Percentage Error (MAPE) for accurate forecasting. Spinach is anticipated to yield 1239.9508 quintals, with an α (alpha) parameter of 0.9 and a MAPE of 38.46%. Water spinach is forecasted to yield 2069.75 quintals, with an α (alpha) parameter of 0.5 and a MAPE of 18.14%. Cucumber is projected to yield 1023.22432 quintals, with an α (alpha) parameter of 0.4 and a MAPE of 31.51%. Consequently, the highest projected yield is for water spinach at 2069,75 quintals.

Ornamental flora of the Cerrado in landscape architecture: a portrait of its practical application

Abstract The rich diversity of the Cerrado flora has great ornamental potential, however it is barely present in Landscape Architecture projects in Brazil and incipient in the commercial market. The study sought to systematize part of the knowledge generated by the experiences of eight professionals who work in the Landscape Architecture field and are part of a spontaneous and growing movement that seeks the development of management techniques and a language referenced by phytophysiognomies of the Cerrado, especially its savannas and grasslands. Information was gathered from semi-structured interviews with eight professionals with practical experience in introducing Cerrado flora species in Landscape Architecture projects and analyzed to identify motivations, composition and language aspects, most-used species, technical aspects of implementation and management and perceptions of market and production chain. Reiterated points were mapped and categorized. Interviews revealed efforts to develop a compositional language referenced by the Cerrado with a predominance of herbaceous species and high species diversity in keeping with the contemporary naturalistic Landscape Architecture movement. A list of 84 potentially ornamental species used by interviewees was compiled. Difficulties and market impasses were identified. Much needed strategies for increasing Cerrado flora species use in Landscape Architecture are: engagement of society via environmental education, communication and marketing; research on Cerrado soil and ecology for species selection; qualification of labor; advocacy for public policies including promotion of production chains, research and education.

UPDATED LIST OF NON-NATIVE ORNAMENTAL PLANTS IN ROMANIA

"The first list of non-native ornamental plants (nNOP) reported as escaped, aturalised or invasive in Romania was published 15 years ago. Since then, new additions to the non-native ornamental flora of Romania ave been reported, while others plants have changed their status. As ornamental horticulture is one of the most important pathways for non-native plant introduction worldwide, we evaluated nNOP at the national level and updated the previous list in order to contribute to the development of tools for preventing, detecting, monitoring and managing the spread of nNOP. The updated list includes 264 taxa. Most of these are casual (199 taxa), 37 taxa are naturalised, and 28 taxa are invasive. In addition, the following characteristics were analysed: family, native range, life form, abundance in the country reported as number of localities and temporal trends. Non-native ornamental flora of Romania is dominated by American and Asian taxa, phanerophytes, hemicryptophytes and therophytes. The most widespread species is Robinia pseudoacacia, used not only for ornamental purposes, but also for its economic value. Many taxa (108 taxa) occur only in two to ten localities. 78 nNOP have been reported in the last 20 years. Six taxa are species of European Union concern (Ailanthus altissima, Asclepias syriaca, Cabomba caroliniana, Humulopsis scandens, Impatiens glandulifera, Myriophyllum aquaticum) and require special measures to control and mitigate their populations."

Performance of foliage ornamentals in hydroponic nutrient solutions

Vertical garden is one of the approach of green building envelope with green facades and green living walls creates a richer ecosystem, enhances biodiversity, improves mental health, alleviates environmental externalization generated by urban areas (Pollution, runoff and heat island effect etc). However, the limitations of vertical gardening system are the choice of plants and the module of growing. Numerous exotic and native ornamentals are suggested for vertical systems based on the requirements. Selection of plants grown under indoor environments with limited space is narrowing down the choice of ornamental flora. On the other hand hydroponics is an alternative sustainable production system under conditions in which resources are limited. Hydroponics is a very young science which has commercial basis during recent days. However, even in relative short period of time it has been adapted in many situations from outdoor to indoor for growing various crops. Hence, an experiment was conducted with Hoagland & Arnon solution (1938), Cooper’s solution (1979), Saparamadu’s solution (2010) and Mattson and Peters solution (2014) and a control with Irrigation water to study the rooting behavior of five plants viz., Devil’s ivy (Epipremunm aureum), Wandering jew (Zebrina pendula), Arrowhead plant (Syngonium podophyllum), Philodendron (Philodendron erubescens), Boat lily (Tradescantia spathacea) under passive hydroponic vertical garden module. The pH was monitored for acidity and basicity range and EC were monitored for salt concentration in all the nutrient solution periodically. Observation on root parameters viz., Number of roots plant -1, Root length (cm) and Root weight (g plant-1) were observed at 30, 60 and 90 days after planting. Results of the experiment revealed that number of roots, root length and root weight exerted maximum values in those plants grown under T3 (Cooper’s solution). Minimum rooting with lowest weight was recorded in T4 (Saparamadu solution) in all the stages of observation in devil’s ivy. Whereas in other four ornamentals viz., Wandering jew (Zebrina pendula), Arrowhead plant (Syngonium podophyllum), Philodendron (Philodendron erubescens) and Boat lily (Tradescantia spathacea) recorded lowest root parameters in T1 (Irrigation water) under 30 days of observation and at 60 and 90 days minimum number of roots, root length and root weight was recorded under T4 (Saparamadu solution).

Landscape Organization of a Sensory Garden for Children with Disabilities

The paper investigates some design peculiarities of public green spaces used by mobility- and visually–impaired citizens. The subject of studying is a sensory garden as a tool enabling to acquire important knowledge, develop skills, control emotions, and maintain self-confidence by people with special needs. The paper aims at establishing the techniques of creating a sensory garden in a visually-impaired children’s school area based on universal (inclusive) design concepts. To this end, the paper generalizes works on forming a universal design for mobility-impaired population; considers ornamental plant assortments and the effect of introducing ornamental flora in the south of Primorsky Krai (Region); a research project has been done on landscape arranging a visually-impaired school area in the town of Artyom, Primorsky Krai (Region). As a result, a sensory garden universal design has been created which takes into consideration emotional, sensual and physical needs of physically-challenged school students who cannot feel the same as other society members in public places due to their special needs. The proposed project solution may have a positive therapeutic healing effect on school students which results from being in nature and which would allow mobility-impaired children to experience the same senses during their walks as ordinary kids do.

Composition patterns of ornamental flora in the Czech Republic

Ornamental plants are an important component of urban floras and a significant source of alien plant invasions to the surrounding landscapes. We studied ornamental flora across 174 settlements in the Czech Republic, Central Europe. The aims of the study were to (i) identify clusters of sites that are defined as distinctive groups of ornamental taxa reflecting environmental or socioeconomic factors and (ii) apply the classification approach which is traditionally used for spontaneous vegetation in order to evaluate the potential of different settlement types to act as source sites of invasive species. The inventories were classified in a similar manner that is generally applied to spontaneous vegetation using the COCKTAIL method. Diagnostic taxa were classified in a repeatable manner into 17 species groups, forming five distinctive clusters with ~70% of sites attributed to one cluster. The species pools of the clusters differed in their representation of species with native or alien status and different life forms. The following clusters were distinguished, based on the prevailing type of settlement: (1) old villas neighbourhoods of towns, (2) upland settlements, (3) modern neighbourhoods, (4) old rustic settlements and (5) modern rustic settlements. Similar to spontaneous vegetation, the classification of ornamental flora reflects both basic natural gradients (i.e. altitude) and man-made factors (i.e. the preferences for certain plants and associated management practices). Alien taxa associated with modern neighbourhoods are characterised by a relatively higher invasion potential than those from, for example, old rustic settlements. This is especially true for woody species which can spread in ruderal habitats as a result of urban sprawl. Our results showed that the classification method, commonly used to analyse vegetation data, can also be applied to ornamental flora.

“Study of Phenology of Woody Flora of Gulmarg and Its Neighbourhood” for Landscape Use

The present investigation entitled “Study of phenology of ornamental flora of Gulmarg and its neighbourhood for landscape use” conducted during the years 2008-2010 in Gulmarg area of Kashmir valley. For this purpose four representative zones including zone A. ferozpur (1880 m.asl) and Tangmarg (2153 m.asl), zone B. Drang. (2218 m.asl) zone C. Doobi ghat (2218 m.asl), Gulmarg (2688 m.asl) and Baba reshi (2703 m.asl) and zone D. khelanmarg (3041 m.asl) were selected and recorded observations on flower emergence by making exploratory trips to these sites. Phonological spectrum of the flora of deciduous trees and shrubs, broad leaf evergreen trees and shrubs, deciduous woody vines, ground covers and evergreen ground cover shrubs revealed maximum availability of flowers during spring followed by summer and autumn.

Exotic species predominates in the urban woody flora of central Chile

The expansion of cities promotes the replacement of local biotas with exotic species causing a decrease in global diversity. As urbanization continues to expand, efforts directed towards the conservation within urban landscapes could support regional biodiversity conservation. The biogeographic region of central Chile displays a native flora of global importance because of its high endemism. Up to date, studies analysing the composition of the floras within the cities are scarce. The present study aims at characterizing the compositional and distributional patterns of the ornamental flora of five cities of central Chile (La Serena, Valparaíso, Santiago, Rancagua, and Talca). For this purpose, we sampled several streets and squares recording all woody species. The species were then characterized by their biogeographical origin and incidence. It was recorded 302 species of which approx. 86% were exotic and 14% were native, a consistent pattern found in the five cities studied; these results contrast with the European urban flora, where native species can usually overcome 50% of the plant species. Almost half of the exotic species had their origin in Asia (including Australasia, Temperate, and Tropical Asia), Europe, and North America. Consequently, the representation of the regional flora within the urban context is low for central Chile, with the native species registered, accounting for only 0.81% of the total species described for the country. Urban habitats could support regional biodiversity conservation, so a shift towards sustainable urban planning could promote local biological conservation.

Wild ornamental plants of Samara

The paper deals with the analysis of wild ornamental flora of Samara. At the moment the system of green spaces in Samara does not meet the norm standard. For planting trees and shrubs cities use plants grown and brought in from other regions of the world in recent years. But we believe that local wild species of plants should also be used for planting trees and shrubs in the city, as they are more adapted to the urban environment of Central Russia, and thus demand less care. Among wild-growing ornamental plants in Samara most ornate types are of the Asteraceae family. For the studied sector of the Samara flora perennial plants are considered to be typical, among them perennial grasses prevail. The analysis of the flora study helped us to come to the conclusion that the most numerous group is mesophyte plants, the leading environmental group on the degree of illumination and dimming are heliophytes. Among the studied plants meadow species of wild ornamental plants prevail. A part of ornamental flora of Samara are species noted in habitats of natural and anthropogenic origin, where the habitats of natural origin (forest, meadow and steppe islands of natural origin among residential areas) prevail. As wild-growing ornamental plants have adapted to the urban environment we recommend to use them for landscape gardening and landscape construction.

Spontaneous and ornamental flora of the park of Lužnica manor near Zaprešić (northwestern Croatia)

century and laid out after the construction of the manor. The estate also comprises farm buildings, vegetable garden and orchards, which all make a func tional whole together with the main manor house. This research has established the presence of 342 plant species belonging to 233 genera and 80 families, 80 taxa of which belong to ornamental flora (a.s. planted) while 262 are spontaneous species. The flora has been analysed according to taxonomy, chorology, life forms and protected species status. It was also compared to some similar areas in the conti nental part of Croatia. According to the chorological composition and life forms, the Lužnica park flora is not significantly different from that in the compared areas. Nevertheless it is important to note that the park, although the smallest of the compared areas, abounds in a relatively large number of species, 6 of which are strictly protected by law. Therefore, we recommend that Lužnica park to be officially recognised as a protected area.

Enhanced removal of exogenous formaldehyde gas by AtFALDH-transgenic petunia

We initiated this study to remediate indoor air pollution caused by volatile organic compounds by using plants. We isolated the glutathione-dependent formaldehyde dehydrogenase gene AtFALDH from Arabidopsis thaliana, inserted it into the expression vector pK2GW7, and introduced the gene into two purebred lines of Petunia hybrida to determine whether the gene would function in this ornamental plant. Seven shoots were regenerated from 248 explants cultured on the Murashige and Skoog basal medium. However, when the regenerated shoots were transferred to the second selection medium, only one shoot survived. The AtFALDH-transgenic T1 seeds were obtained from self-pollination of the single acclimated transgenic plant. These seeds produced 17 AtFALDH-transgenic T1 plants, 13 of which expressed the transgene, as determined by the PCR analysis. Among the 13 AtFALDH-transgenic T1 plants, 10 plants were confirmed by the Southern blot analysis to be identical to the transgenic plants and to possess three copies of the transgene. Furthermore, AtFALDH-transgenic T2 seeds were obtained from the self-pollination of the AtFALDH-transgenic T1 line, and the PCR analysis showed that 81 of the 105 AtFALDH-transgenic T2 plants exhibited the transgene. The transcription of the transgene was confirmed using the real-time PCR analysis in four of five plants that were selected randomly from the 81 AtFALDH-transgenic T2 plants. The AtFALDH-transgenic T2 plants removed 49.0 μg·m−3·cm−2 leaf area of formaldehyde during a 5-h measurement period, as compared with only 38.9 μg·m−3·cm−2 leaf area by the non-transgenic plants (a difference of 25.9%). Future work should focus on developing other AtFALDH-transgenic ornamental flora for use in the phytoremediation of formaldehyde gas.

A Novel Biorational Pesticide: Efficacy of Methionine Against Heraclides (Papilio) cresphontes, a Surrogate of the Invasive Princeps (Papilio) demoleus (Lepidoptera: Papilionidae)

ABSTRACT The Southeast Asian citrus-feeding butterfly Princeps (Papilio) demoleus (L.) was recently introduced into the Americas, causing an imminent threat to citrus production and ornamental flora. The human nutrient amino acid methionine has been shown by us to disrupt aminoacid-modulated ion transport systems in caterpillars and other insect larvae that possess an alkaline midgut. Heraclides (Papilio) cresphontes was bioassayed as a United States Department of Agriculture permitted surrogate of the Florida quarantined P. demoleus to test the potential efficacy of methionine. Larvae were allowed to feed ad libitum on wild lime plants with leaves treated with methionine or proline. Methionine caused 100% mortality in first through fourth instars in a time- and dose-dependent manner, as determined by probit analysis whereas proline was not toxic. Wild lime host plants did not exhibit phytotoxicity with methionine treatments during a 14 d test period. It is concluded that methionine is an effective larvicide against H. cresphontes, and therefore may be a candidate environmentally safe biorational pesticide for use against invasive P. demoleus in the Americas.

Allergenicity of the ornamental urban flora: ecological and aerobiological analyses in Córdoba (Spain) and Ascoli Piceno (Italy)

Comparative ecological and aerobiological analyses of ornamental urban flora in the cities of Cordoba (Spain) and Ascoli Piceno (Italy) identified a group of plants with allergenic pollen whose behaviour is influenced by a number of factors. The geographical position and the resulting climate of both cities favoured the presence of Mediterranean species. In Cordoba, strongly allergenic evergreens introduced during the Moorish period predominated (Cupressus sempervirens, among others), while in the urban area of Ascoli Piceno, Pinaceae were abundant. In both cities, many species of American origin have been introduced for aesthetic reasons, contributing to an increase in the overall allergenicity of urban greenery. The pollen spectrum differed between the two cities: airborne Oleaceae and Cupressaceae pollen abounded in Cordoba, whilst allergenic pollen from surrounding natural environments (Corylaceae) predominated in Ascoli Piceno. These results pointed to a large number of potentially allergenic species in cities, thus highlighting the importance of greater ecological and aerobiological knowledge of allergenic species of urban ornamental flora. Avoidance of more allergenic species when planning new urban green areas could ensure healthier environments for pollen-allergy sufferers.
