摘要:

【目的】分析不同砧木对克瑞森无核葡萄光合性能影响,为筛选优良适宜克瑞森无核葡萄的砧木品种提供参考。【方法】以7种不同砧木5BB、5C、101-14MG、110R、SO4、188-08和贝达嫁接的6年生克瑞森无核和克瑞森无核自根苗为试材,采用SPAD502测定相对叶绿素含量;TPS-2光合仪测定光合参数,运用直角双曲线修正模型和弗伦德利希模型等数据模型对数据拟合,计算饱和光强、光补偿点等指标。【结果】不同砧木嫁接的克瑞森无核及自根苗之间叶片指标存在显著或极显著差异。101-14MG嫁接的克瑞森无核的叶面积和SPAD值最大,达146.85 mm2和44.99,砧木5BB嫁接的克瑞森无核的最大净光合速率最高,达到了17.68 μmol/(m 2·s)。其次为101-14MG,为16.01 μmol/(m2·s),略小于5BB嫁接的,118-08嫁接的克瑞森无核净光合速率最低,为12.31 μmol/(m2·s)。在暗呼吸速率方面表现较好的砧木品种是188-08和贝达,暗呼吸速率仅为1.36和1.33 μmol/(m2·s)。101-14MG嫁接的克瑞森无核光补偿点最高,为95.58 μmol/(m2·s),其次是110R,克瑞森无核自根的光补偿点最低,为45.92 μmol/(m2·s)。砧木101-14MG、5BB嫁接的克瑞森无核及克瑞森无核自根有较高的内禀量子效率和表观量子效率。砧木贝达嫁接的克瑞森无核光能利用率最大,为 1.850%,其次是5BB嫁接的克瑞森无核的光能利用率,为1.625%。【结论】砧木101-14MG明显提高了接穗克瑞森无核葡萄叶片单叶面积和叶绿素含量,砧木101-14MG和5BB砧木嫁接克瑞森无核的叶片最大净光合速率、量子效率、光适应范围等较其它砧木表现优良,较有利于提高接穗克瑞森无核葡萄叶片的光合作用。

Abstract:

【Objective】 To analyze the effects of different rootstocks on photosynthetic performance of Crimson seedless grape with a view to providing reference for the selection of excellent rootstocks suitable for the grape. 【Methods】 SPAD502 was used to determine the relative chlorophyll content of 6 year old Crimson seedless and Crimson seedless self-root seedlings grafted with 7 different rootstocks, 5BB, 5C, 101-14MG, 110R, SO4, 188-08 and Beta. The TPS-2 photosynthetic apparatus was used to measure the photosynthetic parameters, and data models such as right-angle hyperbolic correction model and Freundlich model were used to fit the data, and the saturation light intensity and light compensation point were calculated. 【Results】 The results showed that there were significant or extremely significant differences in leaf indexes between different rootstocks of scion Crimson seedless and self-root seedlings. The leaf area and SPAD of the 101-14MG grafted Crimson were the highest, reaching 146.85 mm2 and 44.99, and the maximum net photosynthetic rate of the stock 5BB grafting was the highest, reaching 17.68 μmol/(m 2·s). The second rate was 101-14MG, which was 16.01 μmol/(m2·s), slightly less than that of 5BB grafting. The net photosynthetic rate of Crimson without nucleation was the lowest in 118-08 grafting, which was 12.31 μmol/(m2·s). Rootstocks with good performance in dark respiration rate were 188-08 and Beta, with dark respiration rate of only 1.36and 1.33 μmol/(m2 ·s). The 101-14MG grafted Crimson nucleus-free light compensation point was the highest (95.58 μmol/(m 2·s)), followed by 110R, and the lowest (45.92 μmol/(m2·s)). The Crimson and the Crimson without nucleus were grafted with stock 101-14MG and 5BB. The utilization rate of Crimson without nucleus was the highest (1.850%), followed by that of Crimson without nucleus (1.625%) with 5BB grafting. 【Conclusion】 The results showed that rootstock 101-14MG significantly increased the leaf area and chlorophyll content of scion Crimson seedless grape. The maximum net photosynthetic rate, quantum efficiency and light adaptation range of rootstock 101-14MG and 5 BB grafted with Crimson seedless grape were better than those of other rootstocks, which is beneficial to improve photosynthesis of scion Crimson seedless grape leaves.
