以菊花小八叶乌塌菜品种为试验材料,利用LED精量调制光源,设红光、蓝光、红/蓝(3/1)、红/蓝(7/1)、白/红/蓝(3/2/1)5个处理,以白光为对照,研究不同光质对乌塌菜光合特性及品质的影响。结果表明:叶绿素含量以红/蓝(7/1)处理最高,且叶绿素总量与红/蓝光比值呈正相关;光合速率、气孔导度、蒸腾速率均以红光处理最高,而蓝光处理下有较高的胞间CO2浓度;不同光质处理对乌塌菜的荧光参数有较大影响,白光的Fm/Fo、Fv/Fo和ΦPSⅡ均最大;红光可以提高可溶性糖含量而蓝光却能提高可溶性蛋白含量,白光能增加维生素C含量。综合分析得出,红/蓝(7/1)有利于增加光合色素含量,提高光合速率和营养品质。

The paper studied the effects of different light qualities on the photosynthetic response and nutrition -al quality of savoy.Juhuaxiaobaye savoy as material ,red light,blue light,red/blue (3/1) light,red/blue (7/1) light and white/red/blue (3/2/1) light generated by light-emitting diode were applied .And white light generated by fluorescent lamps was used as control .The results showed that the contents of chlorophyll ( a+b ) was highest under red/blue (7/1) light treatment,and chlorophyll (a+b) contents were correlated with red/blue ratios posi-tively.The photosynthetic rate (Pn),stomata conductance (Gs),transpiration rate (Er) were biggest under red light.Whereas intercellular CO 2 concentration ( Ci) was highest under blue light .The fluorescence parameters were significantly affected by light quality .Values of the maximal photochemical efficiency of PS Ⅱ( Fv/Fm) ,Fv/Fo andΦPSⅡwere highest under white light .Red light can increase the soluble sugar content but blue light increase solu-ble protein content,the white light can increase Vitamin C content .Comprehensive analysis,red/blue (7/1) is ben-eficial to increase the chlorophyll ( a+b) contents and improve photosynthetic rate with nutritional quality .
