凹脉金花茶和东兴金花茶的繁殖试验研究

Studies on the Reproductive Methods of Camellia impressinervis and C. tunghinensis

对凹脉金花茶和东兴金花茶进行播种、扦插、嫁接、空中压条4种方法繁殖试验。结果表明：凹脉金花茶和东兴金花茶种子播种发芽率达859／5以上；6月份扦插比2月份扦插的生根率高209／6～30％，100mg·L^-1NAA处理对插条的根系萌发有明显的促进作用；嫁接繁殖以10月份为宜，凹脉金花茶10月嫁接的成活率达70％以上；采用空中压条方式繁殖，凹脉金花茶和东兴金花茶都容易生根，繁殖的植株易形成一定的冠幅，可加快成苗的速度。

The reproductive experiment of two golden camellias species Camellia impressinervis and C. tunghinensis was carried with four different test methods：direct seed sowing, cutting, grafting and air layering. The results showed that the seed germinating rates of the two golden camellias reached more than 85%. The rooting rate of cutting in the June was 20%-30% higher than those in the February, in which and the treatment dipped in 100 mg·L^-1 NAA had better effect on promoting rooting rate. The best month of engraftment was in October, and the survival rate of graft of C. impressinervis reached more than 70%. Air layering could easily produce rooting system, and the reproduced individuals had a relative rapid crown growth.
