【摘要】 萘乙酸浸泡葡萄苗木根系12h,可有效地提高根系皮层内淀粉酶活性,从而促进淀粉向还原糖的转化,有利于新生根中蛋白质合成。萘乙酸处理使葡萄根系皮层中含水量和可溶性物质增加,处理显著地增加了新根量,但抑制前期地上部枝叶生长。更多还原

【Abstract】 After soaked in NAA solution for 12h, the activity of amylase in cortex of grape seedling roots was efficiently enhanced, thus transformation from starch to reducing sugar was accelerated, and the synthesis of protein in the new roots was promoted. The treatment also made the moisture content and the content of soluble substances in root cortex increase. Although the growth of shoots and leaves at the preceding stage was inhibited, the number of the new roots was notably increased.更多还原
