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.

The Mangoes: Their Botany, Nomenclature, Horticulture and Utilization provides a comprehensive discussion of existing mango species and their value in the common mango (Mangifera indica) industry. It covers mango species growing in very dry areas, like savannahs; species growing on inundated lands; at altitudes over 1000 m in the tropics and at higher latitudes outside the tropics; under monsoon climate conditions and under constantly wet conditions; and so-called wild species that compete in flavor with the common mango. The book begins with an overview of the genus Mangifera, covering distribution, ecology, morphology, and development. The remaining chapters discuss the phytochemistry and chemotaxonomy of the Anacardiaceae with special emphasis on Mangifera; conservation of Mangifera species; a historical overview of the development of knowledge of Mangifera; subdivision of the genus; species of uncertain position; and excluded species. The book also includes a list of references along with indexes to scientific names, vernacular names, and collection numbers. The present text was written for horticulturists and mango growers. However, it may also be useful to scientific botanists, ecologists, students, and teachers.

In recent years there has been a growing awareness of the importance of reproductive biology to crop production and there has been a tremendous increase in research on reproductive structures of higher plants. Presented here is a wide information of different aspects of micro- and macrosporogenesis, pollen-stigma interaction and recognition, pollen tube growth, cytoskeleton, in vitro and in vivo gamete fusion, and incompatibility. The most advanced techniques employed in studies on reproductive biology of higher plants are described in detail.

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.
