摘要：

以北方白黄瓜幼苗为试材，用蓝、绿、红发光二级管(LED)单色光进行单色光和混合光照射诱导处理，分析了光质对Fp685、Fp735、Fp685/ Fp735、F685、F735、 F685/ F735和Y（II）的影响。3种LED单色光源（蓝、绿、红）照射诱导下，随着光强的增加白黄瓜叶片叶绿素荧光曲线OJIP中P点呈现快速上升趋势。其中，Fp685主要表现为蓝光>绿光>红光；而Fp735均表现为绿光下高，红蓝光下低；Fp685/ Fp735荧光比值均表现为蓝光最高，绿光和红光下较低。混合光得到的荧光曲线的P点出现早于单色光照射，且P混合>P单色光加和。混合光荧光值计算得到的F685/F735比值始终低于单色光荧光加和值计算得到的F685/F735比值。各个单色光质下的PSⅡ实际光化学量子产量表现为：Y（II）绿光> Y（II）红光> Y（II）蓝光。

Abstract:

The objective of our study was to analyze the effect of light qualities on Fp685、Fp735、Fp685/ Fp735、F685、F735、 F685/ F735 and Y（II）of Chlorophyll fluorescence in green leaves green leaves induced by blue, green and red light-emitting diode (LED) in northern white cucumber seeding. With the increase of light intensity, the P in OJIP of Chlorophyll fluorescence curve showed a fast rising. Fp685 were in the order of red>blue>green, but Fp735 were in the order of green >red≈ blue. However, the order of blue>green≈ red were observed for the ratio of Fp685/ Fp735.The point of P appeared earlier under the mixed light than under single light, and Pmix>Psingle. The ratio of F685/ F735 always lower under the mixed lights than under single light. The order of Y（II）green> Y（II）red> Y（II）blue were observed for the Yield of PSⅡ by single light.
