据《果树学报》2015年第5期《LED光质对“夏黑”葡萄光合特性和生理指标的影响》(作者余阳等)报道,在遮光条件下,研究不同的LED光质对葡萄叶片光合特性和生理指标的影响。以嫁接的夏黑葡萄为试验材料,对葡萄叶片进行不同光质处理,测定分析了光质对葡萄叶片净光合速率、气孔导度、胞间CO~2浓度、蒸腾速率、光合色素含量与酶活性的影响。结果发现,与对照相比,不同的LED光质均显著提高了夏黑葡萄叶片的净光合速率(Pn)、气孔导度(Gs)、胞间CO2浓度(Ci)以及蒸腾速率(Tr),并且有利
According to “Fruit Tree Journal” 2015 the fifth period “LED light quality” summer black “grape photosynthetic characteristics and physiological indicators of” (the author Yu Yang, etc.) reported that in the light conditions, the study of different LED light pairs Photosynthetic characteristics and physiological indices of grape leaves. The grafted summer grapes were used as experimental materials to study the effects of light quality on the photosynthetic rate, stomatal conductance, intracellular CO 2 concentration, transpiration rate, photosynthetic pigment content, Effect of activity. The results showed that Pn, Stoichiometry (Gs), intercellular CO2 concentration (Ci) and transpiration rate (Tr) were significantly increased by different LED light qualities compared with the control, And good
