摘要：

Triazine (0.6 mM) quenched the chlorophyll fluorescence emission at 686 nm, selectively reduced the biosynthesis of linolenic acid (C-18:3), lowered the ratio of unsaturated/saturated fatty acids in thylakoid membranes and percentage of total glycerides in the extracted oils, and extremely enhanced ethylene production by seedlings. These effects were partly reversed by the addition of 100 g m(-3) of vitamins (thiamine > nicotinic acid > pyridoxine).
