摘要
通过对时间、扦插基质、植物生长调节剂和插穗部位4个因素对白玉仙茶两个品系进行扦插繁殖研究。结果表明白玉仙茶Ⅱ扦插成活率比白玉仙茶Ⅰ高15%,且生长势明显;夏季嫩枝扦插,分别比白玉仙茶Ⅰ冬季和春季扦插成活率提高13%和23%,但对白玉仙茶Ⅱ作用不明显;扦插基质为1/2普通苗床土+1/2黄沙的成活率比全部用黄心土的约高5%;合适浓度的植物生长调节剂IBA对扦插成活促进明显,但高浓度反而有抑制作用;插穗部位几乎不影响扦插成活率。
Effects of cutting time, cutting substrate, plant growth regulators and shoot position for cuttings on cutting propagation were studied using eultivars Baiyuxian tea Ⅰ and Ⅱ. The results showed that the survival rate of cuttings Baiyuxian Tea Ⅱ was 15 % higher than Baiyuxian Tea Ⅰ. The survival rate of cutting from summer shoots was 13% and 23% higher than those from winter and spring shoots in cultivar Baiyuxian tea Ⅰ.
