摘　　要：为了解决油茶组培苗根系发生困难的问题,将油茶无菌短枝组培苗分别扦插在运用"0.618黄金水位"原理制作的"黄金杯"和扦插常用的传统营养杯中,两种营养杯中分别填入以1︰1的珍珠岩与草炭的混配基质、细河沙及红心土,就不同营养杯和不同基质处理对油茶组培苗生根的影响情况进行了对比试验。结果表明:采用1︰1的珍珠岩与草炭的混配基质,将油茶无菌短枝组培苗扦插在运用"0.618黄金水位"原理制作的"黄金杯"中,可使油茶组培苗在30天内发生出10.68条/株、平均根长为7.52㎝的根系,其发根率为100%。To solve the different problem of root system development of tissue culture seedlings in Camellia oleifera,tissue culture seedling from C.oleifera asepsis short-branches were planted in ＂gold cups＂ made with the ＂0.618 gold level＂ principle and traditional nutrition cottage cups,filled with fine sand,red soil and mixed substrate of pearl stone and plant ash（1 ︰ 1）,and the effects of different nutrition cups and substrates on rooting of tissue culture seedlings in C.oleifera were compared.The results showed that taking the mixture of pearl stone and plant ash（1 ︰ 1） as substrate,tissue culture seedling from C.oleifera asepsis short-branches in ＂gold cups＂ made with the ＂0.618 gold level＂principle,had 10.68 roots per plant within 30 days,average root length was 7.52cm,and the rooting rate reached 100%.
