1·The two-part rubber tree (Hevea brasiliensis) is a superior clone grafted on a seedling family.
在橡胶树优良有性系实生苗上嫁接优良无性系，即形成两合树。
2·In natural rubber cultivation, planting materials adopted are the high yielding Grafted Hevea Brasiliensis.
天然橡胶生产栽培中采用的种植材料是高产芽接树。
3·This result indicates that the self-rooting juvenile-type clone of Hevea brasiliensis is a fast growing and high yielding planting material.
说明橡胶自根幼态无性系是一种速生、高产的种植材料。
4·The rubber tree (Hevea brasiliensis) has been an important economic crop which has a large-scale cultivation in the tropical and subtropical regions, and 99% natural rubber comes from it.
巴西橡胶树是热带、亚热带地区大范围种植的一种重要的产胶植物，99%以上天然橡胶来源于巴西橡胶树。
5·The relationship between the effect of exogenous jasmonic acid (JA) on the induction of secondary laticifer differentiation and the distribution of JA in the seedling of Hevea brasiliensis Mull.
中的分布和运输的特点，并分析其与机械伤害和外施茉莉酸对巴西橡胶树次生乳管分化的诱导效应之间的关系。
