Allelopathy Journal

Pollen allelopathy plays key role in normal plant fertilization in biocenosis. Allelochemicals released from the pollens of foreign spp. on the stigma of other spp. interferes with the pollen germination or tube growth, stigma or style receptivity, ovule development, respiration, seedling germination and/or growth), leaf chlorophyll, seed set and non-specialist pollinators or nectarivores. Besides these allelochemicals also affects the reproductive success or failure of recipient plant spp. and leads to weed-crop and crop-weed interactions, when many crops and weeds exist together. Pollen allelopathy may delay the flowering in weeds to less favourable season or diurnal period to reduce the weeds pressure, hence, it may be used in Ecological Weed Management. This review provides the Current Status of Allelopathy Research.
