以2年生盆栽山葡萄品种“双优”为试材,利用14C示踪技术对山葡萄不同生育时期、不同部位同化产物的运转分配规律进行了研究,结果表明:山葡萄同化产物从开花到果实着色前以叶片为分配中心,从果实着色起果实成为同化产物分配中心,采收后由于养分回流主蔓和根系是同化产物分配中心。同化产物的运转方向遵循着向上大于向下、同侧大于对侧和集中供应生长中心的原则。
Taking “Shuangyou”, a 2-year-old potted grape variety as test material, 14C tracing technique was used to study the distribution of assimilation products during different growth stages and assimilation in different parts of grapevine. The results showed that: Leaves for the distribution center, the fruit from the fruit coloration become assimilation product distribution center, after harvest due to nutrients return to the main vine and root is the assimilation product distribution center. The direction of operation of the assimilate product follows the principle of upward upward, downward downward, ipsilateral greater than contralateral and centralized supply of growth centers.
