Book Synopsis Pollination Biology by : Dharam P. Abrol
Download or read book Pollination Biology written by Dharam P. Abrol. This book was released on 2011-10-05. Available in PDF, EPUB and Kindle. Book excerpt: This book has a wider approach not strictly focused on crop production compared to other books that are strictly oriented towards bees, but has a generalist approach to pollination biology. It also highlights relationships between introduced and wild pollinators and consequences of such introductions on communities of wild pollinating insects. The chapters on biochemical basis of plant-pollination interaction, pollination energetics, climate change and pollinators and pollinators as bioindicators of ecosystem functioning provide a base for future insights into pollination biology. The role of honeybees and wild bees on crop pollination, value of bee pollination, planned honeybee pollination, non-bee pollinators, safety of pollinators, pollination in cages, pollination for hybrid seed production, the problem of diseases, genetically modified plants and bees, the role of bees in improving food security and livelihoods, capacity building and awareness for pollinators are also discussed.

Book Synopsis Pollinator diversity in Mango (Mangifera indica L.) across GKVK campus: an overview by : Mahesh Joshi
Download or read book Pollinator diversity in Mango (Mangifera indica L.) across GKVK campus: an overview written by Mahesh Joshi . This book was released on . Available in PDF, EPUB and Kindle. Book excerpt: Flower initiation in mango (var: “Mallika”) commenced at 21.83 ± 1.58 days after bud development and staminate : hermaphrodite flower ratio was 1:0.29. In each flower, one fertile and four staminoids were present. Staminate and hermaphrodite flowers opened during 0730-1000 hrs. and 0800-1100 hrs. and in them anther dehiscence occurred at 27.1 ± 3.1 and 29.3 ± 4.8 min. after anthesis, respectively. Fruit set (no./panicle) was 2.90 ±1.27 in unbagged and zero in bagged inflorescence. Total longevity of each flower was 81.96 ± 2.14 hrs. Forty five insect species found foraging on the inflorescence belonged to Hymenoptera (60%), Diptera (24.44%), Hemiptera (6.67%), Coleoptera (4.44%) and Lepidoptera (4.44%). Shannon-Weiner Diversity Index (H) values ranged from 1.201-1.586 during different hours of the day, with peak ‘H’ values during 0900-1100 hrs. (1.597-1.619). Highest ‘H’ value (1.551) was recorded at >90 per cent flowering stage. Berger-Parker index (d) for dominance during 25, 50, 75 and >90 percent flowering was highest for E. obliquus (d=0.40, 0.40, 0.36 and 0.34). E. obliquus, Chrysomya sp., A. florea and A. cerana indica spent 11.83, 8.33, 5.29 and 3.76 sec. on each flower, respectively. All four species spent maximum foraging time during 1000-1100 hrs. E. obliquus, Chrysomya sp., A. florea and A. cerana indica visited 36.38, 42.93, 57.33 and 69.40 flowers /5 min., respectively. Maximum bee visitation was recorded at 0600-0700 hrs. and 1700-1800 hrs. Further, E. obliquus, Chrysomya sp., A. florea and A. cerana indica visited 13.03, 18.18, 27.84 and 31.78 flowers per inflorescence. Significant negative correlation (p=0.001) was observed between the number of flowers visited per inflorescence and time spent w.r.t. all the four species.
