摘要
[目的]研究不同整型方式对设施葡萄叶片光合作用和果实品质的影响。[方法]以4年生红提葡萄为试材,其整形方式设FI型、L型、V型和扇型(CK)4种,对不同整型葡萄中部叶片的平均叶面积、叶绿素含量、光合速率、Rubisco活性和果实品质进行测定与比较。[结果]与传统的扇形整型方式相比,L型和FI型整型方式明显提高葡萄的叶面积和平均单果重;在果实迅速膨大期,L型还显著提高叶片的叶绿素含量、气孔导度和Rubisco活性,使叶片的光合速率显著提高;L型、FI型和V型整型方式均不同程度提高葡萄平均单果重和可溶性固形物含量,降低果实可滴定酸含量。[结论]4种整型方式中,以L型叶片的叶绿素含量、Rubisco活性和光合速率最高,平均单果重和可溶性果形物含量也最高。
[ Objective] The research aimed to study the effects of different shaping modes on the photosynthesis and quality of grape in greenhouse. [ Method I With 4-year-old Vitis vinifera var. Red Globe as the tested material, 4 kinds of shaping modes were set up as FI type, L type, V type and fan type （CK） and the mean leaf area, chlorophyll content, photosynthesis rate, Ruhisco activity in the leaves on the middle part of grape trees with different shaping modes and their fruit quality were determined and compared. [ Result] Compared with the traditional shaping mode of fan type ,the types of L and FI could significantly increase the leaf area and the average berry weight and the L type could significantly increase the chlorophyll content, stomatal conductance and Rubisco activity of leaves and increase the photosynthesis rate of leaves at last in the rapid growth period of berry; all the shaping types of L, FI and V could increase the average berry weight and the soluble solid content in fruit to different degree and decrease the of titrab]e acidity content in fruit. [ Conclusion ] Among 4 kinds of shaping modes, the chlorophyll content, Rubisco activity and photosynthesis rate of ]eaves treated with L type were highest as well as the average berry weight and the soluble solid content in fruit treated with L type were highest.
