Synopsis This issue brings out the information on advances in pollen-spore research in India. The topics covered are aeromycoflora, pollen relationships with honey bees, pollen calendars of honey bees and pollen and spore allergy. The information on these topics is of immense value for academicians, agriculturists, apiculturists and biologists. The authors of each papers have discussed the present trends in pollen-spore research. Further, pollen calendars of honey bees are very important for bee-keeping in different eco-regions of India. The information on aeromycoflora and their incidence in different seasons in different environmental settings is very valuable for agriculturists to frame remedial measures for allergic symptoms caused by different fungal and pollen spora and for farmers to avoid exposure to such allergenic spora during their peak occurrence. The information on pollen morphological characteristics enables us to understand the relationships between plants and honey bees in terms of pollination. The list of allergenic pollen plants presented in this book helps us to avoid such plants while selecting plant species in plantation programmes or in green belt development programmes, especially in urban centers. All these various aspects of structural and functional characteristics of pollen and spore flora have been discussed in great details by the respective authors. Therefore, this book is a valuable source of information for those who are working in this discipline.
