Plant growth and seed yield in annual chrysanthemum as influenced by growth chemicals and pinching

A field experiment was conducted at Horticulture Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi to know the effect of pinching, gibberelic acid (GA3) and salicylic acid (SA) on growth and seed yield characters of annual chrysanthemum. The treatments constituted of two level of pinching i.e. no pinching and pinching and each at three levels i.e. GA3 (100 ppm, 200 ppm and 300 ppm) and SA (100 ppm, 150 ppm and 200 ppm) along with control (distilled water). Significantly maximum no. of primary branches/plant, stem diameter, fresh weight of leaf, no. of seeds/peduncle, weight of seeds/peduncle and seed yield/plant was recorded with pinching. However, early seed ripening was noted with no pinching treatment. GA3 at 100 ppm exhibited maximum no. of primary branches/plant. Significantly maximum leaf area index was observed with GA3 300 ppm treatment. Among various doses of salicylic acid, SA 100 ppm recorded maximum plant spread, no. of seeds/peduncle, weight of seeds/peduncle seed yield/plant and test weight of seed. Maximum fresh weight of leaf was observed with SA 150 ppm. However, maximum stem diameter was registered with SA 200 ppm. Interaction of pinching with GA3 and SA gave significant effect on all growth and seed parameters except no. of primary branches/plant, stem diameter and fresh weight of leaf.

Profitability of Annual Chrysanthemum (Chrysanthemum coronium L.) Flower Production as Influenced by Application of Mycorrhiza and Vermicompost

To check the effect of mycorrhiza on growth and flowering of chrysanthemum, an open field experiment was conducted the effect of vermicompost and mycorrhizal treatments on profitability of Chrysanthemum coronarium L. Treatments comprises of 04 mycorrhiza treatments (No application, Glomus mosseae, Acaulospora laevis, Gigaspora margarita) and 04 vermicompost doses (0 g/ m2, 500 g/ m2, 750 g/ m2, 1 kg/ m2). The experiment was laid out in factorial randomized block design with three replications. Chrysanthemum plants showed improved growth and flowering with the application of vermicompost and mycorrhiza. In the present investigations, economic analysis of different treatments reveals that application of treatment M3V2 (Gigaspora margarita + Vermicompost @ 750 g/m2) resulted in highest benefit cost ratio (5.83) closely followed by benefit cost ratio of the treatments; M2 V2 (Acaulospora laevis + Vermicompost @ 750 g/m2) and M1 V2 (Glomus mosseae + Vermicompost @ 750 g/m2).

Effect of Mycorhizal and Vermicompost Application on Growth and Quality Flower Production of Annual Chrysanthemum (Chrysanthemum coronium L.)

Annual Chrysanthemum (Chrysanthemum coronarium L.) is one of the most widely cultivated garden flowers and is highly suitable for loose flower, pot culture and bedding purposes. The objective of this research was to evaluate the effect of different mycorrhizal strains and vermicompost on growth and flowering of Chrysanthemum coronarium. The treatments comprise of 4 mycorrhiza treatments (No application, Glomus mosseae, Acaulospora laevis, Gigaspora margarita) and 4 vermicompost doses (0 g/ m2, 500 g/ m2, 750 g/ m2, 1 kg/ m2). After one year experiment, results revealed that chrysanthemum plants showed improved growth and flowering with the application of vermicompost and mycorrhiza. The highest plant height (107.00 cm), maximum number of side shoots per plant (18.22), maximum number of flowers per plant (107.88), flower diameter and flowering duration (57.00 days) was recorded with the application of Glomus mosseae + vermicompost @ 1 kg/m2 while maximum flower weight (8.64 g), maximum flower yield (902.36 g) and shelf life (8.40 days) was recorded with Gigaspora margarita + vermicompost @ 1 kg/m2). Thus, integration of mycorrhiza and vermi-compost serve as a way for sustainable chrysanthemum flower production.

Heterosis for growth and yield traits in annual chrysanthemum (Glebionis coronaria [L.] Cass. ex Spach.)

A line x tester analysis was carried out involving five lines (White Majestine, AACS-3, Sarpan White, Sarpan Yellow and Garden Aids) and three testers (Dharwad White, Dharwad Yellow and Bagalkot Local) were analyzed for heterosis for 8 characters in annual chrysanthemum. The experiment was conducted at the Department of Floriculture and Landscape Architecture, Kittur Rani Channamma College of Horticulture, Arabhavi, Karnataka during 2020-21. Sarpan White × Bagalkot Local and Sarpan Yellow × Dharwad White exhibited Significant negative heterosis for plant height and 50 per cent flowering, respectively. White Majestine × Bagalkot Local and Garden Aids × Bagalkot Local reported significant heterosis for flower yield per plant and seed yield per plant, respectively.

Cell selection for increasing resistance of ornamental plants to copper.

Cell selection was used to obtain copper-resistant plants. Developed technologies for obtaining copper-resistant plants Agrostis stolonifera and Chrysanthemum carinatum can be applied to other plant species. We obtained copper-resistant plants Festuca rubra, Brachycome iberidifolia and Linum perenne. The concept of obtaining plants resistant to copper has been developed. This concept consists of two methods. The first method is applicable when calli is highly sensitive to copper. The second method is applicable when calli are moderately sensitive to copper.

Impact of different drying methods and desiccants on storage quality of annual chrysanthemum and gerbera

The present experiment entitled, “Impact of different drying methods and desiccants on storage quality of annual chrysanthemum and gerbera” was carried out at the laboratory of Floriculture and Landscape Architecture, Department of Horticulture, College of Agriculture, JAU, Junagadh during the year 2019-2020 to know the impact of different drying methods and desiccants on storage quality of annual chrysanthemum and gerbera. The experiment was laid out in completely randomized design with factorial concept and two factors i.e. drying methods viz. sun drying and shade drying and desiccants viz. river sand (red), river sand (black), sea sand, silica gel, borax powder and replicated thrice. Flowers were dried properly as per treatments and observations were recorded. In case of storage parameters, shade dried flowers with sea sand resulted in acceptable flower colour with less mechanical damage. Along with that another treatment combination shade drying with borax powder resulted in less mechanical damage to flowers. However, acceptable shape with less attack of pest and disease noticed in sun drying with silica gel. It can be concluded from the present investigation that shade drying with sea sand produced quality dry flowers of annual chrysanthemum and gerbera during storage.

Effect of different drying methods and desiccants on drying quality of annual chrysanthemum and gerbera

The present experiment entitled, “Effect of different drying methods and desiccants on drying quality of annual chrysanthemum and gerbera” was carried out at the laboratory of Floriculture and Landscape Architecture, Department of Horticulture, College of Agriculture, JAU, Junagadh during the year 2019-2020. The experiment was laid out in completely randomized design with factorial concept and two factors i.e. drying methods viz. sun drying and shade drying and desiccants viz. river sand (red), river sand (black), sea sand, silica gel, borax powder and replicated thrice. Significant variation was observed in annual chrysanthemum and gerbera flowers for different drying methods with regard to sensory or quality parameters. Shade drying resulted in better quality parameters such as bright colour, well maintained shape, smooth petal texture, less mechanical damage during drying. Significant variation found among desiccants and sea sand embedding resulted better quality parameters. Along with sea sand another desiccant borax powder resulted in smooth textured flowers with less mechanical damage. Interaction effect was found significant except few days and shade drying with sea sand was found best for all the quality parameters.

The effect of Colchicine on Vicia faba and Chrysanthemum carinatum (L.) plants and their cytogenetical study

We have prepared various colchicine concentrations and applied them on seedling of Chrysanthemum carinatum (2n = 18) and seeds of Vicia faba (2n = 12). Colchicine-induced polyploidy was reported in Chrysanthemum carinatum (2n = 4x = 36) and Vicia faba (2n = 4x = 24) plants. This research explains the polyploidy in respective plants which successfully results in apparent morphological and cytological changes in polyploid plants compared to the control plants. Phenotypic characters exhibited that polyploid plants initially had slightly slower growth, stronger stems, thicker and larger leaves, larger flowers, and seeds and then increases abruptly. There was an increment in cytological characters such as cell size, chiasma frequency in polyploid plants as compared to the control plants. Growth patterns, morphology, pollen staining, and seed sets were recorded in this work. However, the main emphasis was laid on the behavior of chromosomes of isolated polyploids.

Standardization of in vitro regeneration protocol in annual chrysanthemum

An efficient in vitro regeneration protocol of annual chrysanthemum (Chrysanthemum coronarium L.) was standardized by using leaf explants. Leaf segments (0.25 cm2) were taken from three weeks old in vitro raised plantlets and cultured on MS basal medium containing BAP, NAA and Kinetin at different concentrations. Maximum survival of micro shoots (86.67%) and shoot regeneration (82.79%) was achieved in half strength MS medium supplemented with BAP (0.5 mg/l) and NAA (1.0 mg/l) (T6). Half strength MS medium supplemented with GA3 (0.5 mg/l) (T3) showed thick shoots (5.78 cm) with dark green leaves and the highest rooting (90.00%) was recorded in the treatment including half strength MS basal medium supplemented with NAA (0.5 mg/l) (T3). The newly regenerated plantlets recorded maximum plant survival (76.60%) in medium containing cocopeat, perlite and vermiculite (1:1:1) (T2) supplemented with half strength MS inorganic broth. The study concluded that, the established protocol may be utilized in producing true to type plants which are otherwise difficult in the species. This protocol may help for large scale multiplication of desired types to fulfil the demand of quality planting material of C. coronarium.

Ornamental plants adapted to urban ecosystem pollution: lawn grasses and painted daisy tolerating copper.

Lawns and flower are major aesthetical and environmental elements of the urban ecosystem. However, harsh urban conditions such as pollution by heavy metals are unfavorable for plants. For example, copper is toxic for ornamental plants, limiting the spread of lawn grass and flowering plants. Therefore, here we hypothesized that plants could be adapted to urban conditions by breeding. We first showed the possibility of using environmental biotechnology in urban greening to obtain, tolerating copper flowering plants and lawn grasses. We tested the adaptation of creeping bentgrass (Agrostis stolonifera L.) and painted daisy (Chrysanthemum carinatum Schousb.) to сopper. We measured Cu resistance in the next generations of those plant species. Results show that some next generations of plant regenerants have increased resistance up to 100 mg/kg Cu for Agrostis stolonifera, and up to 30 mg/kg for Chrysanthemum carinatum. Our findings thus imply that city plants may be adapted and improved by сell selection. Our approach thus represents a novel biotechnology consisting of adapting plants to pollution by сell selection.

Investigation of genetic variability in annual chrysanthemum for yield and it’s contributing characters

Annual chrysanthemum, botanically known as Chrysanthemum coronarium L., is an annual under the chrysanthemum group of flowers. The experiment was conducted during 2019-2020 at NARP, Ganeshkhind, Pune in Randomized Block Design with 18 genotypes as treatments and two replications of Annual Chrysanthemum. There were 14 genotypes and four checks in the experiment. The main objective was to study the extent of variability in available genotype of annual Chrysanthemum. It was observed that genotypic coefficient of variation (GCV) was lower than phenotypic coefficient of variation (PCV) for all the traits under study. The highest value of genotypic and phenotypic coefficient of variation was recorded for the character number of ray florets (57.21), (57.57) respectively. The estimates of GCV and PCV were of high magnitude in number of branches per plant, number of ray florets, number of flowers per plant, weight of 10 flowers, yield of flowers per plant, yield of flowers per plot and yield of flowers per hectare. The estimate of heritability ranged between Plant spread in N-S direction (58.60%) to Number of ray florets (98.80%). High estimate of heritability (98.80%) was recorded for Number of ray florets. The range of genetic advance was from 0.38 to 12067.69. The character, Yield of flowers per hectare exhibited highest genetic advance (12067.69%), followed by Yield of flowers per plant (203.40%), followed by Yield of flowers per plot (150.69%). The lowest value of genetic advance was reported for character disc diameter (0.38%). Therefore, these characters should be given top priority during selection breeding in annual Chrysanthemum.
