Medium with higher concentration sucrose can promote bulblet enlargement but inhibit bulblet formation. The best matrix for the highest surviving rate and best growth situation was pearlite/soil (3:1). The number of bulb scales surviving and regenerating decreased significantly as the increasing of days after the treatment of high temperature 37oC. The regeneration rate can be about 40% for 20days. The effectiveness of eliminating LSV with the method got to more than 95% which was significantly higher compared with the control.

蛭石：土、珍珠岩以及珍珠岩：土作为基质时，均能达到较高的成活率和株高，但在珍珠岩：土为3：1作为基质移栽组培球，其成活率和生长状况最佳。37℃热处理随着处理天数的增加，处理后培养鳞片的成活率和子球再生率显著下降，但处理20天子球再生率只能达40%左右，但LSV检出率明显低于未处理的种球，脱毒率达95%以上。

Efficiency:It uses Zhu Ji pearl fresh water and hydrolyzes into power,which maintains effective ingredient to the further extend.It can provide abundant water to skin,and its butterfat,vitamin and minerals can be easily absorbed by your skin.
