研究了贝达、1103P、101-14、3309C、140Ru、5C、SO4和抗砧1号等8种葡萄砧木对87-1叶片的栅栏组织厚度、海绵组织厚度、叶片厚度、栅/海比、比叶重、叶绿素含量和净光合速率的影响。结果表明,贝达/87-1和1103P/87-1砧穗组合的海绵组织、叶片厚度显著厚于其他砧穗组合;栅栏组织厚度以140Ru/87-1、1103P/87-1和贝达/87-1砧穗组合最厚;比叶重以贝达/87-1和1103P/87-1砧穗组合最大。叶绿素含量、叶绿素a、叶绿素b含量和净光合速率,同样是贝达/87-1和1103P/87-1砧穗组合最大。综上,87-1以贝达和1103P做砧木,其叶片质量与光合性能最佳。此外,不同砧穗组合的叶片厚度、栅栏组织厚度、海绵组织厚度、叶绿素总含量、叶绿素a、叶绿素b含量和比叶重与其净光合速率呈显著正相关关系。
The effects of eight grapevine rootstocks including Beida, 1103P, 101-14, 3309C, 140Ru, 5C, SO4 and Zigou 1 on the thickness of palisade tissue, thickness of sponge tissue, leaf thickness, Specific leaf weight, chlorophyll content and net photosynthetic rate. The results showed that the thickness of the sponge tissue of combination of Beida / 87-1 and 1103P / 87-1 was significantly thicker than that of other scion / panicle combinations; the thickness of the palisade tissue was 140Ru / 87-1,1103P / 87-1 and Beida / 87-1 rootstock combination is the thickest; specific leaf weight in the combination of Beida / 87-1 and 1103P / 87-1 scion maximum. Chlorophyll content, chlorophyll a, chlorophyll b content and net photosynthetic rate were the highest in combination with Beida / 87-1 and 1103P / 87-1 roots. In summary, 87-1 with Beida and 1103P as rootstocks, the leaf quality and photosynthetic properties of the best. In addition, leaf thickness, palisade tissue thickness, sponge tissue thickness, total chlorophyll content, chlorophyll a, chlorophyll b content and specific leaf weight were positively correlated with net photosynthetic rate.
