Integration of the pollen database PONET into PalDat with new features for light microscopy

Free access to scientific data, knowledge and technology transfer has become more and more important in science, at universities, governmental institutes, and in our society in general. In an interdisciplinary project initialised by palynologists at the University of Vienna and the Austrian Agency for Health and Food Safety Ltd (AGES), the world’s most comprehensive database PalDat has been expanded by more than 2000 datasets from the PONET database, comprising high resolution light microscopy (LM) micrographs of hydrated pollen. The main aim of this fusion of knowledge was to share digital data in a secure way and to ensure users of various disciplines free access to reliable pollen data. The project was finally completed in 2021. In the course of the expansion, additional data entry fields regarding LM description have been added, and new features, such as a search function for orders and families, have been implemented in the new version 3.4 of PalDat. A global online submission and publication tool for palynological data to PalDat, including review and editorial process, assures easy knowledge transfer and facilitates a continually increasing number of datasets and taxa contributed from scientists all over the world. The free accessible online pollen database PalDat is maintained by members of the Division of Structural and Functional Botany (University of Vienna).

Preparation and Quality Evaluation of Ready to Serve (RTS) Wheatgrass Juice

Wheatgrass is an inexpensive and efficient source to provide all the required nutrients and medicinal benefits for a healthy body. The major objective of this study is to formulate a health-beneficial beverage that could be organoleptically accepted by people of all age groups, to bring forward a new product from wheatgrass that has mostly remained unexplored. The wheatgrass harvested on the 9th day (optimized on the basis of chlorophyll, tannin, total polyphenols, flavonoids and DPPH radical scavenging activity) was taken for study. The wheat seeds (WK 1204 variety), collected from Agriculture Botany Division, Nepal Agriculture Research Council were used for the preparation of ready-to-serve juice. Eight different formulations of RTS were prepared with the help of Design-Expert®, version 7, keeping juice content 7-13%, TSS 9-16 °Bx and constant acidity at 0.3%. Response Surface Methodology, D-optimal design was adapted for the formulations. The optimization of the formulation was intended to be carried out based on sensory analysis. Proximate and phytochemical (Chlorophyll, Polyphenol, Flavonoids, Tannins and Antioxidant properties) composition of 9th days harvested wheatgrass, its extracted juice and the final product was also carried out. The statistical analysis (two-way ANOVA, no blocking) was done in order to evaluate the outcomes of sensory analysis. There was a significant difference for sensory attributes like flavor, taste, body and overall acceptability at p<0.05, whereas color wasn’t found to be significantly different. Sensory analysis revealed that the beverage consisting of 12.8% Wheatgrass juice, 12.5°Bx TSS and 0.3% acidity was considered best among all the combinations.

Screening of soybean genotypes for pod blight resistance under natural inoculum pressure

Soybean, an important oilseed and legume crop, has risen in popularity in recent years owing to its value in terms of yield and nutrition. Pod Blight caused by Colletotrichum truncatum (Schwa). Andrus and Moore can cause heavy yield loss ranging from 16-100 percent. The present investigation was conducted at Botany Farm, Division of Botany, College of Agriculture, Pune during Kharif 2020 to screen soybean genotypes for pod blight resistance on the basis of percent pod infection (PPI) under field conditions. The experimental material consisted of 30 elite genotypes of soybean obtained from the Officer in charge, Agriculture Research Station (ARS), Kasbe Dig raj, Sangli. Most of the genotypes were found to be moderately resistant (6-25% PPI). None of the genotypes were found immune or resistant. The genotype showing least pod blight incidence was DSb-33.

Identification of the Promising Lines of Lentil for Varietal Improvement

This study aimed to evaluate and identify promising lentil genotypes for varietal enhancement, conducted at the Nepal Agriculture Research Council (NARC), Agriculture Botany Division (ABD), Khumaltar. Eighteen genotypes sourced from the National Grain Legumes Research Program (NAGRC) and the International Centre for Agriculture Research in Dry Areas (ICARDA) was assessed. Various parameters, including plant stand, flowering duration, maturity period, plant height, yield-related traits, chlorophyll content, and disease severity, were recorded. Notable correlations were found between grain yield and key attributes such as pods per plant, 1000-seed weight, chlorophyll content, final plant stand, and branches per plant. Genotypes exhibiting high chlorophyll content, optimal plant height, increased branching, greater seed weight, more pods, enhanced plant stand, and lower disease susceptibility displayed positive correlations with grain yield. Among these, genotype ILL-10071 demonstrated the highest average grain yield, highlighting its potential for further breeding and improvement programs. Other promising genotypes included ILL-9924, ILL-3338, ILL-10265, ILL-1920, ILL-6458, ILL-6465, and RL-71, showcasing significant grain yield and warranting consideration in future varietal enhancement initiatives. These findings underscore the importance of specific traits in lentil genotypes and provide valuable insights for breeding programs aimed at enhancing lentil productivity.

Optimum Sowing Date And Fertilizer Management For Durum Wheat Genotype DWK 38 In Mid-Hills Condition

Durum wheat is relatively new crop for Nepal and research on durum wheat were carried out only by Agriculture Botany Division of Nepal Agricultural Research Council (NARC). To find the optimum sowing time and fertilizer dose for mid-hills conditions of Nepal, an experiment was carried out in 2017/18 and 2018/19 at Agronomy Division Experimental farm in Khumlatar at an altitude of 1360 masl. The experimental design was factorial randomised complete block design. There were 3 fertilizer level and 4 sowing date constituting 12 treatment combinations. From the combined analysis over years, we found that plant height, days to heading, days to maturity, thousand grain weight and grain yield were found significnat in sowing date whereas number of tillers per square meter, straw yield and harvest index were significant in fertilizer doses. Combined analysis of both years yielded mean grain yield of 5.2 t/ha and thousand grain weight of 48.6 gm respectively. Precipitation during reproductive period (March[1]April) in 2017/18 contributed in higher grain yield than 2018/19. Optimum sowing date of durum wheat for khumaltar condition is no later than 26 November and optimum dose of fertilizer is 125:75:50 N:P2O5:K2O kg/ha.

Estimation of Genetic Parameters of Different Wheat Genotype Traits in Chitwan, Nepal

This research was carried out to estimate the genetic parameters of fifty wheat genotypes received from the Agriculture Botany Division, Nepal Agriculture Research Council (NARC), Khumaltar, Lalitpur, in the winter season of 2014/2015 at Agriculture and Forestry University (AFU), Chitwan, Nepal. The experiment was performed in an alpha lattice design with two replications in five blocks in each replication and ten plots in each block. The analysis of variance showed highly significant differences among the genotypes for all the studied traits except spike length. This implies that, except for spike length, all other traits exhibited genetic variability. The phenotypic coefficient of variation (PCV) was generally higher than the genotypic coefficient of variation (GCV) for all characters. The difference between PCV and GCV was large in spike length followed by grain weight per spike, the number of grains per spike, grain yield, thousand-grain weight, and harvest index indicating that these traits are affected by the environment as well. Moderate to high heritability associated with a high genetic gain was observed for days to flag leaf appearance, panicle length, thousand-grain weight, grain yield, and harvest index indicating the involvement of additive gene action. Grain weight per spike, number of grains per spike, thousand-grain weight, biological yield, and harvest index were significantly correlated with grain yield indicating their important contribution to grain yield. WK 2525, WK 2437, and WK 2506 were three promising genotypes in terms of grain yield.

The chlorophyll contents and growth performances of West Java (Indonesia) jobtears (Coix lacryma-jobi) accessions under low light intensity conditions

Abstract. Juhaeti T, Setyowati N, Syarif F. 2020. The chlorophyll contents and growth performances of West Java (Indonesia) jobtears (Coix lacryma-jobi) accessions under low light intensity conditions. Biodiversitas 21: 5178-5185. The research was carried out to study the shading tolerance of five jobtears (Coix lacryma-jobi L) accession collected from Bandung, Kuningan, Garut, Sukabumi, and Sumedang West Java Indonesia. The existence of shade-tolerant jobtears was important to increasing its cultivation for food diversification effort. The research was conducted in the Botany Division, Research Center for Biology, Indonesian Institute of Sciences. The experimental design was a Randomized Complete Block Design with two factors. The first factors were 0%, 25%, 50%, and 75% shading intensity. The second factors were five West Java jobtears accession, namely Bandung, Kuningan, Garut, Sukabumi, and Sumedang accession. The shading intensity set up artificially by the black plastic net. Jobtears seeds planted on planting beds on 70x100 planting distance. The variable observed included microclimate, plant growth, leaf chlorophyll content, and grain production. The result indicated that jobtears accession showed differences in growth and production characters. Low light intensity significantly affected plant growth and production. The plant height, leaf number, and chlorophyll content variables increased until 50% shading intensity and then decreased by 75% shading. Plant production decreased by the increased of shading intensity. The Bandung and Garut accessions can be determined as a potential low-light tolerant accession due to its better growth and production compared with others and the lowest percentage of decreased production. For further research, the Garut and Bandung accession can be used as a genetic biodiversity source for shading tolerance breeding efforts.

Multivariate analysis of soybean genotypes

The experiments were conducted using randomized complete block design with three replications at the research field of Agriculture Botany Division, Khumaltar, Lalitpur, Nepal in 2016 and 2017 to evaluate sixteen soybean genotypes using multivariate analysis. The results showed the significant (p &lt;0.05) differences among genotypes for plant height, days to maturity plant and hundred seeds weight and grain yield. Cluster analysis based on these traits, sixteen soybean genotypes were divided the genotypes into four clusters. The soybean genotypes grouped into cluster 1 showed the highest value for days to maturity. The genotypes belonged to cluster 2 had the highest values for grain yield and plant height. The principle components analysis showed that PC1 and PC2 having eigen values the highest than unity explained 76.6% of total variability among soybean genotypes attributable to plant height, days to maturity, number of pods/plant, 100 seed weight and grain yield. The genotypes showing wide diversity in cluster and principle component analysis can be used as parents in hybridization programs to maximize the use of genetic diversity and expression of heterosis and develop high yielding soybean varieties.

Celebrating a New Division of Botany at SICB: An Introduction to the Integrative Plant Biology Symposium

The Society for Integrative and Comparative Biology (SICB) should, in theory, be a home for scientists working across the entire Tree of Life. In practice, SICB has remained principally a society that supports integrative zoological research. Here we highlight a broad collection of what we consider to the best in integrative and comparative plant biology, gathered together for a special symposium at the 2019 SICB meeting. This symposium and special issue mark the initiation of a new Division of Botany within SICB, which we hope will usher in a new era of SICB where botanists and zoologists engage, collaborate, and celebrate together in this especially creative period of integrative and comparative biology.

Variability Study of Biofortified Bread Wheat Genotypes for Grain Zinc and Iron Concentration, Yield and Yield Associated Traits at Khumaltar, Lalitpur, Nepal

Bread wheat ( Triticum aestivum L.) is third major cereal crop of Nepal where cereal based foods represent the largest proportion of the daily diet. Lack of diverse food habit in the country is resulting micronutrient deficiency. This could be addressed by introducing biofortified bread wheat genotypes. This field research was conducted at Agriculture Botany Division, Khumaltar, Lalitpur to study the variability of biofortified bread wheat genotypes for grain zinc, iron, yield, yield attributes and identify high yielding genotypes with high grain zinc and iron concentration. 50 wheat genotypes (47 biofortified, 3 checks) were tested in alpha lattice design with two replications. Data on grain zinc, iron, yield and yield attributes were recorded and analyzed (α=5%). Genotypes differed significantly for the studied traits which provide an opportunity to improve the existing germplasms for targeted traits and environment. Grain yield was correlated positively with effective tiller, plant height, days to maturity, grains per spike and negatively with thousand grain weight. Grain zinc and iron concentration were significantly positively correlated but had positive non-significant relation with grain yield suggesting simultaneous improvement of both micronutrients without compromising grain yield is possible. Effective tiller and peduncle length can be used as selection criteria for high grain yield and micronutrient concentration respectively. Superior genotypes containing higher grain iron, zinc and yield can be used as parent in breeding for developing zinc and iron enriched varieties. &#x0D;

Gilmore, S.1 and Hill, K.D. (National Herbarium of New South Wales, Royal Botanic Gardens, Sydney, NSW 2000, Australia; 1 Present address: Division of Botany and Zoology, Australian National University, Canberra, ACT 0200, Australia) 1997. Relationships of the Wollemi Pine (Wollemia nobilis) and a molecular phylogeny of the Araucariaceae. Telopea 7(3): 275–291. Sequences were obtained for the rbcL gene from chloroplast DNA of the newly discovered Australian conifer Wollemia nobilis (Araucariaceae), 5 species of Araucaria and 4 species of Agathis. Phylogenetic analysis of our new data and other available sequences indicate that 1) Araucariaceae is monophyletic; 2) Agathis and Araucaria are both monophyletic; 3) Wollemia is the sister group to Agathis; 4) the Pinaceae are the sister group to all other conifers, although the monophyly of the conifers is not unequivocally demonstrated. The utility of rbcL for deriving a robust phylogeny of the Araucariaceae and of the conifers is discussed.
