本文研究了不同波长的红光RL、蓝光BL、黄光YL、绿色GL和远红光FR光对拟南芥花粉管伸长的影响。hypogaea。短时间暴露于RL的花粉引起增强管的伸长，这种效果被FR和BL降低。RL和FR的作用是相互可逆的。同样，蓝光的抑制作用可以被IAA和核黄素分别克服，而乙酰胆碱和GA 3模拟RL效应。RL和IAA能提高过氧化物酶（PO）和苹果酸脱氢酶（MDH）的活性，而BL能提高IAA氧化酶的活性。讨论了不同光谱组成的光在控制花粉管伸长中的调节作用。
The effect of light of different wave lengths (red RL, blue BL, yellow YL, green GL and far-red FR) on pollen tube elongation were studied in A. hypogaea. Short exposure of pollen to RL caused enhanced tube elongation and this effect was reduced by FR and BL. The effects of RL and FR were mutually reversible. Similarly, the inhibitory effect of blue light could be overcome by IAA and riboflavin separately whereas acetylcholine and GA3 mimicked the RL effect. The activities of peroxidase (PO) and malate dehydrogenase (MDH) were increased by RL and IAA whereas BL increased the activity of IAA-oxidase. The regulatory role of light of different spectral composition in controlling pollen tube elongation is discussed.
