Abstract:

Laboratory studies were conducted to assess the purple nutsedge tuber viability and sprouting behavior under various durations of water soaking conditions. Tuber viability assessment study resulted that one per cent tetrazolium chloride solution recorded the maximum tuber viability with the presoaking in water for two hours recorded the maximum viability percentage. In tuber sprouting assessment results expressed that the tuber sprouting increased with respect of increased water soaking durations while the maximum germination percentage (72 per cent) was observed with the soaking duration of 6 hours and also earlier sprouting was observed (1.3 days) while untreated tubers emerged only after 3.8 days. However the over soaking of tubers did not found to influence the germination of tuber in the present study.
