Cyanamide is an allelochemical produced by hairy vetch (__Vicia villosa__ Roth.). Its phyotoxic effect on plant growth was examined on roots of onion (__Allium cepa__ L.) bulbs. Water solution of cyanamide (2โ10ย mM) restricted growth of onion roots in a dose-dependent manner. Treatment of onion root
Visible light of moderate intensity causes two and perhaps three types of division inhibition in Euglena gracilis and related cells. Fluorescent light causes a general inhibition of growth and division which is temperature-dependent. Pigmentation or complex organic media partially lifts this inhibit
