摘要： 实验以不同季节的茎尖(含茎段)为材料,采用不同基本培养基,研究确定西洋杜鹃组织培养适合的基本培养基类型,植株再生的可能途径,以及适宜的培养条件。结果表明:①低盐分浓度及高比值NH4+/NO3-的基本培养基Read培养基适合西洋杜鹃;②最适外植体为摘花芽后萌发的顶芽茎尖;③最佳取材时间为3~5月;④培养条件:温度25±2℃,光照16h/黑暗8h,光照强度1500~2500lx。

Abstract: In view of studying the suitable type of medium, probable way of explant regeneration and suitable condition of culture for tissue culture in R. hybridn, a experimentation was established in which shoot tip from different seasons and a series of different medium were employed. The results are as follows:①Read medium with low mineral salt concentration and high ration of NH4+/NO3- is suitable for R. hybridn microculture; ②The optimal explants are shoot tips of end buds excised from R. hybridn in 3~5 months; ③All the cultures are kept under the temperature of 25±2℃, illuminated for 16 hours per day, and light intensity was 1500~2500lx.

Key words: R. HYBRIDN, TISSUE CULTURE, RAPID PROPAGATION
