摘要
在单色LED灯光照条件下,以青花6号花生品种为材料,研究了不同光质对花生幼苗光合色素含量及光合特性的影响.结果表明：与自然光照相比,蓝光（445-470nm）可显著提高花生幼苗比叶面积、叶绿素a/b值和类胡萝卜素含量,净光合速率、气孔导度、蒸腾速率较高,胞间CO2浓度较低,光合效率显著提高;红光（610-660nm）显著提高了叶片叶绿素含量,降低了比叶面积、叶绿素a/b值和类胡萝卜素含量,光合效率低于自然光照;绿光（515-520nm）和黄光（590-595nm）不利于光合色素的积累,显著抑制了花生幼苗叶片的光合作用.
This study explored the effects of different light quality on photosynthetic pigment contents and photosynthetic characteristics of peanut （Qinhua 6） seedling leaves. The results showed that, compared with natural light, blue light （445-470 nm） could significantly improve the specific leaf area （SLA）, chlorophyll a/b value and carotenoid content of peanut seedlings. Meanwhile, the net photosynthetic rate, stomatal conductance, and transpiration rate were higher, the intercellular CO2 content was lower, and the photosynthetic efficiency was improved significantly under blue light. Red light （610-660 nm） could improve the chlorophyll content significantly, and reduce SLA, chlorophyll a/b value and carotenoid content, with a lower photosynthetic efficiency than natural light. Green light （515-520 nm） and yellow light （590-595 nm） were not conducive to photosynthetic pigment accumulation of leaves, and significantly inhibited leaf photosynthesis of peanut seedlings.
