JA is a crucial signal molecule in inducing cambia to differentiate the secondary laticifer, and a local high level of JA in cooperating with other plant hormones, especially cytokinin, is prerequisite for the secondary laticifer differentiation.

研究表明，茉莉酸是誘導(dǎo)乳管分化的關(guān)鍵信號(hào)分子91pao国产在线观看，局部高水平的茉莉酸是誘導(dǎo)維管形成層細(xì)胞分化次生乳管所必需的，同時(shí)需要其它激素的協(xié)同作用无修正小视频在线观看视频。

By using the "mechanical wounding"experimental system estabilished by us, and light- and electron microscopy, autoradiography and radioisotope technique, immuno-fluorescence localization, homologous clone and RACE technique, in situ mRNA hybridization and ELISA et al., we investigated the relationship between the transportation of exogenous JA and the secondary laticifer differentiation, the relationship between the producton and accumulation of endogenous JA and the laticifer differentiation from cambia, and the effect of appling exogenous jasmonates on the natural rubber production.

Rubber trees initiate laticifer differentiation in June and July while no laticifer differentiation occur during the periods from November to May under natural conditions on Hainan Island. Application of jasmonates induced laticifer formation in both immature and mature rubber trees. Tapping and/or pre-tapping enhanced the ability of vascular cambia to differentiate the secondary laticifers.
