清远笔架茶植物组织培养育种与常规育种方式的比较

Comparison of Plant Tissue Culture Breeding and Conventional Breeding of Bijia Tea

通过利用笔架茶的种子胚、侧芽作为外植体进行植物组织培养育苗与常规的播种、扦插两种育苗方式进行比较试验,用种子胚、用侧芽作外植体进行植物组织培养育苗,育苗率分别为89.63%±1.68和94.43%±2.25,用种子进行常规播种育苗和用穗条进行扦插育苗,育苗率分别为75.33%±2.08和85.67%±1.53。结果显示,植物组织培养技术育苗明显优于常规播种和扦插两种育苗方式。

In this paper, we use seed embryos and lateral buds of Bijia tea for the comparison of methods between plant tissue culture, conventional seeding and cuttage breeding. It carried out that the induction rates of plant tissue culture were 89.63%±1.68 when using seed embryos and 94.43%±2.25 while we used lateral buds. And when we used seed embryos for regular breeding and cuttage breeding, the induction rates were 75.33% ±2.08 and85.67% ±1.53. The results showed that plant tissue culture technology was superior to conventional seeding and cuttage breeding methods.
