摘要
研究了不同浓度二烷氨基乙醇羧酸酯（DA-6）对草莓叶片光合作用和果实品质的影响。结果表明，与对照相比，10和20mg·L^-1的DA-6提高了叶片的Pn和Gs。在处理后7～21d，20mg·L^-1的DA-6显著提高了叶片的Rubisco活性和可溶性蛋白含量。在整个处理过程中，40mg·L^-1的DA-6对叶片Pn、叶绿素含量和Rubisco活性有抑制作用，但与对照差异不显著。10、20和40mg·L^-1的DA-6处理都能提高果实品质．其中20mg·L^-1处理显著提高了果实品质。
The effects of DA-6 at different concentrations on leaf photosynthesis and fruit quality were studied in strawberry. The results showed that DA-6 of 10 and 20 mg· L^-1 could increase leaf photosynthetic rate and stormatal conductance compared with control. Moreover, 20 mg · L^-1 DA-6 significantly enhanced Rubiseo activity and soluble protein content from 7 to 21 days after treatment. However, the results also indicated that 40 mg· L^-1 DA-6 had inhibiting effects on leaf photosynthetic rate, chlorophyll content and Rubisco activity and no significant differences found with control during the whole treatment period. On the other hand, DA-6 applied in different concentrations all increased the quality of strawberry and 20 mg·L^-1DA-6 showed the remarkable effect.
