Caffeine lnduced Morpho-cytological Variability in Fenugreek, Trigonella foenum-graecum L.

抄録

The present investigation deals with the morphological and cytological studies of caffeine treated plants of Trigonella foenum-graecum. The untreated plants being normal while the treated populations showed a number of meiotic abnormalities such as univalents, laggards, bridges, nondisjunction, stickiness, cytomixis and precocious movement of chromosomes etc. The spectrum of abnormalities increased with an increasing concentration of caffeine. Lower doses of caffeine exhibited stimulatory effect on plant height, number of branches, pods, and internodal length while the higher doses caused inhibitory effect on morphological characters. Observed abnormalities
