摘      要：The present article deals with the use of tree barks as a natural trap for airborne spores and pollen grains in *** study carried out at the southern part of Beijing Botanical Garden,Institute of Botany,Chinese Academy of Sciences has yielded a variety of palynomorphs mostly belonging to tree *** methodologies for extraction of palynomorphs from tree barks have been *** samples were collected from three taxa,i.e.,Paulownia fortunei Hemsl.(Scrophulariaceae),Quercus dentata Thunb.(Fagaceae),and Picea meyeri Rehder&***(Pinaceae)having different bark *** with a comparatively soft and fissured bark is believed to have a greater potential for trapping airborne spores and pollen grains compared to the stiff and less fissured barks of *** and the scaly bark of *** barks yield better data in terms of quantity and quality of trapped pollen and *** present study throws new light on the modern pollen rain,spore-pollen dispersal,and their deposition in and aroundBeijing Botanical Garden,and other different parts of China.
