The results showed that NAA at low concentrations 0.1~0.2 mgL^(-1 was more beneficial for root induction, the rate of rooting was up to 100%. 1/4MS was more suitable to deal with the plantlet rooting and form small bulb. The optimal ratio of IBA and AC for rooting was 2.0 mgL^(-1) IBA+0.1%AC. The in vitro growth of plantlets were the strongest, and survival rate was 100% after incubating at 4℃ for 4 weeks when the diameter of bulblet was ≥9 mm.

你可于5月至6月间，选择节间较短的当年生半木质化枝条，自基部切下作插穗，顶端保留3片至5片小叶，若枝条过长，亦可截去顶梢，扦插介质可用兰花泥。高山腐殖土。蛭石。珍珠岩或黄心土等，厚约15厘米至20厘米，下铺7厘米至8厘米的排水层；把介质喷湿后，将插穗插入基质中，插穗入土深度约为穗长的1/2，家庭少量扦插也可选用大花盆盛装介质代作扦插苗床。插后加盖塑料薄膜保湿，温度控制在25℃至30℃之间，加设荫棚遮挡阳光，或挪放于树荫下，始终保持扦插基质湿润，东鹃约过1个月即可生根，而西鹃则要60天至70天才能生根。9月后可减少遮荫时间，并追施稀薄尿素液一次，浓度约为0.2%，10月下旬即可上盆。

The results of the treatment with hormones indicated: Soaked in solution of 200ppm IBA for 5 minutes and quickly dipped into the No. 3 ABT rhizogenesis powder solution, the survival rate and the growth of"Kerman"seedlings are enhanced and accelerated; quickly dipped into the No. 3 ABT rhizogenesis powder solution of 200ppm and 400ppm, the survival rate and the growth of UCBI and P. atlantica are advanced greatly.
