~(14)C—乙烯利在茶树上喷洒后,其沉积量叶比花高2倍左右。而消失速度比花快,喷洒后第3天消失约达42％,以后逐渐缓慢,喷洒后第50天叶部乙烯利残留量在1ppm以下。 ~(14)C—乙烯利在以通过茶树的根部和茎部进入茶株,并运转到其他部分,而在各部位的积累量不同,花>叶,在花中花柄>花瓣。~(14)C—乙烯利可以从叶面进入叶的组织,但运转出去的量很少。 茶树枝条在含有~(14)C—乙烯利水培液中培养后,捕集从茶树枝条上~(14)C—乙烯利所释放出来的~(14)C—乙烯,而未发现~(14)CO_2。
~ (14) C-ethephon sprayed on tea trees, the amount of leaf deposition is about 2 times higher than the flower. The disappearance of speed faster than the flowers, spraying the first 3 days disappeared about 42%, gradually slow after the first 50 days after spraying ethephon residues below 1ppm. ~ (14) C-Ethephon entered the tea plants through the roots and stems of tea trees and ran to other parts. However, the accumulation of C-ethephon differed in different parts of the flowers. ~ (14) C-ethephon can enter the leaf tissue from the foliage, but is rarely run out. After the branches of tea tree were cultured in the culture medium containing ~ (14) C-ethephon, the ~ (14) C-ethylene released from the ~ (14) ) CO_2.
