Abstract

                                Studies on the field performance of differentially aged seeds using seed and plant leaf extracts on seed yield and quality of paddy variety IR 20 revealed that the effect of accelerated ageing mimicked the natural ageing as was observed through reduction in germination, seedling length and drymatter production after hydration-dehydration either with water or using blackgram seed leachate (1:1) for 8 and dried back to original moisture content. The effect of ageing could be alleviaed through this treatment and this was reflected on enhancement of plant height, number of tillers/plant, days to 50% flowering, panicle length and other yield parameters.
