In dormant period of vascular cambia activity , mechanical wounding with small scale had little effect on inducing secondary laticifer differentiation .
但在形成层活动的休眠期，小面积的机械伤害不能诱导萌条的次生乳管分化。
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 .
Another potential advance came this week as cambia , a non-profit group in australia , and that country 's queensland university of technology unveiled the global initiative for open innovation .
The effect of season changes in vascular cambia activity , development stage of new shoots and terminal buds , and intensity of mechanical wounding on secondary laticifer differentiation induced by mechanical wounding in rubber tree was investigated by means of experimental morphological techniques so as to optimize the experimental system for secondary laticifer differentiation induced by mechanical wounding .
