Abstract


Lemma and palea play an important part in retaining dormancy in rice seeds due to the presence of functional inhibitors than mechanical resistance. The bioassay in the extract of intact seeds (lemma and palea) indicated clearly certain facts with regard to germination of embryo in sucrose solution. The embryo germination was nil between RF 0.7500,833 and it is possible that certain inhibitors or toxic substances may be responsible for the decrease in germination percentage. Effect on root length appeared to suggest that there was quite en amount of inhibition in most cases on elution of chromatograms,
