植物调节剂促进橡胶树籽苗芽接苗接穗萌发与生长研究

摘要

In order to impro ve the survival rate of the Mini-Budding seedling and Shorten seed seedling bud grafting seedling stage of rubber tree, 4 kinds of plant hormones were used for germination test and 2 kinds of plant regulator were used for growth test, respectively. The results showed that 400μmol/L 6-BA and 200 μmol/L GA3 can both promote the grafting seedling germination as well as shorten germination time. 500 μmol/L NAA and 20 μmol/L Zeatin did not affect for germination. After germination, 10~40μmol/L Zeatin and 50 μmol/L DA-6 has the effect of promoting growth, and improve the photosynthetic efficiency of and chlorophyll contents. This study lay a good foundation for research and development of new growth regulator for grafting seedling.%为缩短橡胶树籽苗芽接苗育苗期，加快籽苗芽接苗接穗萌发与生长，采用4种植物激素对橡胶树籽苗芽接苗的萌发情况和2种植物调节剂对籽苗芽接苗生长情况的影响进行研究。结果表明：400μmol/L 6-BA和200μmol/L GA3均有促进籽苗芽接苗萌发、缩短抽芽时间的作用。500μmol/L NAA和20μmol/L ZT对萌发没有作用。萌发后，10～40μmol/L ZT和50μmol/L DA-6有促进接穗增长的作用，并提高叶片光合效率和叶绿素含量。
