| 摘 要： | 研究了光对光麦离体叶片乙烯形成的影响。结果表明，以ＮａＨＣＯ３形式给叶片光促进乙烯产生，反之，不供给ＣＯ２光对乙烯形成起抑制作用。

| Abstract: | The influence of light on ethylene production and senescence of wheat leaves were studied:Adding NaHCO 3 to the culture solution to supply CO 2,light stimulates ethylene production.On the other hand,without supply of NaHCO 3 light inhibites it .Even if leaves were incubated with exogenous ACC the inhibiting effect of light remains.DCMU clearly prevents the stimulating effect of light,but sodium benzoate,a free radical scarvenger,has no effect.Regardless of stimulating or inhibiting ethylene production,light clearly prevents the leaf chlorophyll breakdown.It is concluded that a double effects of light on ethylene production of detached leaves exits.The site of inhibition in ethylene biosynthesis pathway is at the conversion of ACC to ethylene,and the stimulation action of light is related to photosynthesis.
