"The cultivated variety of the non-native I. coccinea, Dwarf Red Coccinea @RC), is most popular and widely spread all over Thailand. However, knowledge about its pollen morphology and fertility for plant breeding purposes, is limited. This study aimed to investigate the quantity, viability and germinability of pollen grains collected from the flowers of DRC at different times on a summer day, particularly from 8 AM to 4 PM. Pollen quantity was determined using a haemacytometer while its viability and germinability were examined after staining with 1% acetocarmine and allowing the pollen to germinate on a modified agar-gelled germination medium. The pollen collected at 10 AM had the highest pollen density (53.3x104 pollen/mL) and viability percentage (72.05'/0). When these pollen were allowed to germinate on an artificial medium suppleented with various sucrose concentrations, the highest in vitro pollen germinability was found at the medium containing 10% sucrose. Hence, the best time to collect the I. coccinea, cv. 'Dwarf Red Coccinea' pollen was at 10 AM. However, further investigations are recommended on the effects of daily or hourly environmental changes particularly, ambient temperature and humidity, on the quantity and quality of harvestable pollen as well as on the pistil phenology, to develop a more complete breeding strategy for the Ixora species"

"This book include 25 chapters contributed by more than 40 distinguished entomologists and introduces the latest progress in entomology, from molecular biology, insect-plant interactions and insecticide toxicology, to emerging technologies in pest management. "

"The authors of this book have collected the most recent advances and discoveries applied to breeding for abiotic stresses in this book, starting with new physiological concepts and breeding methods, and moving on to discuss modern molecular biological approaches geared to the development of improved cultivars tolerant to most sorts of abiotic stress."

"This book offers definitive coverage of the sea beet, the wild ancestor of all cultivated beets, which grows mainly on Mediterranean shores. The editors have collected both scientific and historical source material, illustrations and references."

"Covering the forefront of crop stress research, this book reviews progress in distinguishing and diminishing the effects of biotic stress from pests and pathogens, and abiotic stress caused by chemicals, radiation and extremes of temperature and moisture."

"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."

"The pollination biology of North American orchids brings together, for the first time, a comprehensive treatment of this information for all native and introduced North American orchids found north of Mexico and Florida. It provides detailed information on genetic compatibility, breeding systems, pollinators, pollination mechanisms, fruiting success, and limiting factors for each species. Distribution, habitat, and floral morphology are also summarized. In addition, detailed line drawings emphasize orchid reproductive organs and their adaptation to known pollinators.This, the first of two volumes, furnishes a brief introduction to the general morphology of the orchid flower and the terminology used to describe orchid breeding systems and reproductive strategies. It treats the lady’s-slippers of genus cypripedium, subfamily cypripedioideae, and nine genera of the subfamily orchidoideae, including the diverse rein orchids of genus platanthera."

"The present volume presents essential information on advancements in oilseed production, processing and utilization. Advances in the technology of seed processing to produce oil and oil quality for edible and industrial applications are well presented, followed by hybrid technology, biotechnology, oil technology and meal quality for animal nutrition. The following areas are also covered, the potential for oil in developing biodiesel markets, fatty acid long chains and their derivative, pollination management, and safety of pollinators from harmful effects of pesticides. This volume also includes an economic assessment of oilseed integrated pest management (IPM) programs in different regions of the world."

"This comprehensive volume encompasses recent innovations and practice in the production and use of different oil crops, including brassica, sunflower, safflower, cottonseed, castor, olive, coconut, oilpalm, sesame, groundnut, and soybean. "
