| 摘 要： | 研究了6-BA 对葡萄果实生长及碳、氮同化物运输、分配的影响。结果表明, 果穗浸蘸100 或200 mg/L 6-BA , 均可明显提高坐果率, 对果粒大小、可溶性固形物含量影响较小。6-BA 处理14CO2饲喂叶,抑制了饲喂叶14CO2同化物的输出, 但6-BA 处理饲喂叶上方正在生长的“库叶”, 则增加了饲喂叶同化物的输出。62BA 在盛花和盛花后10 d 浸蘸花序2 次, 增加了饲喂叶14CO2 、14C - 谷氨酸(14C2Glu) 向穗轴及果实的输入。

| Abstract: | For 7-year-old Grape (Vitis vinifera ×V. labrusca cv. Fenghou) , inflorescence were treated with 6-BA at the rate of 100 , or 200 mg/ L in full bloom. The results showed that 62BA treatment markedly increased fruit set. However, there was no significant effect of 62BA treatment on fruit length (L) or fruit diameter (D), L/D ratio and total soluble solids of the fruit juice. Both 1 or 32year2old grape potted (V. vinifera ×V. labrusca cv. Jingya) were used as materials to test for the effect of 62BA on translocation and distribution of carbon (14CO2) and nitrogen 〔14C2Glutamic acid (14C2Glu) 〕assimilates. The result showed that 14CO2-fed leaves of 12year-old‘Jingya’grape with foliar daub at the rate of 50 mg/L 6-BA inhibited translocation of 14CO2-assimilates from fed2 leaves. However , leaves over 14CO2 2fet leaves with foliar daub at the rate of 50 mg/ L 62BA increased translocation of 14CO2-assimilates from 14CO2-fet leaves. For 32year-old‘Jingya’grape, inflorescence were treated with 6-BA at the rate of 200 mg/ L in full bloom and it repeated 10 days after the first treatment. Translocation of 14CO2- assimilates or 14C2- Glu-assimilates from 14CO2- or 14C2-Glu2treated leaves to fruits were enhanced, distribution of 14CO2- or 14C2- Glu assimilates to stem and other leaves were decreased. |
