本研究以牛皮杜鹃组培苗为供试植物，通过多因子交叉重复试验对影响牛皮杜鹃组培苗快速生长的各主要因素及其水平的作用进行了探讨，旨在探索并建立一种牛皮杜鹃种苗快速生长的调控方法。结果表明：最适合牛皮杜鹃组培苗快速生长的主要因素及其水平是光照时间为13 h· d-1、营养液追施间隔时间为21～22 d、光照强度为700～800 lx和温度为26℃。经过25 d的调控处理，牛皮杜鹃组培苗纵向生长高度和横向直径分别达到17．6 cm和6．0 mm，对照组仅分别达到8．8 cm和2．0 mm；50 d后纵向生长高度和横向直径分别达到26．0 cm和7．4 mm，而对照组仅分别达到10．2 cm和2．9 mm。初步得到牛皮杜鹃种苗速生的优化组合，该组合将有利于牛皮杜鹃种苗的快速生长。

We used the plantlets of Rhododendron chrysanthum Pall.to study the main factors with different levels by repeated experiments with multi factorial for establishing a control system of plantlets fast growing of R.chrysanthum.The the main factors with levels for plantlets fast growing of R.chrysanthum are under the light hours of 13 h· d-1 , the interval time of topdressing nutrient solution of 21-22 days, the light intensity of 700-800 lx and the temperature of 26℃.The longitudi-nal growth height and transverse diameter of plantlets of R.chrysanthum were 17.6 cm and 6.0 mm in 25 d, and 26.0 cm and 7.4 mm in 50 d, respectively.The growing height and stem diameter of contrast plant were only 8.8 cm和2.0 mm in 25 d, and 10.2 cm and 2.9 mm in 50 d, respectively.We got the optimization for plantlets fast growing of R.chrysanthum.
