摘要
垂叶榕树(Ficus benjamina)和琴叶榕树(F.lyrata)是美国广泛栽培的观叶植物,现已由一些公司和实验室进行大规模商品性快速繁殖生产。在生产中常采用一般嘌呤型细胞分裂素(CTK)类生长调节剂如BAP或2 ip等来促进芽的繁殖。
Thidiazuron (TDZ) was ussed as a cytokinin in micropropagation of two Ficus species for comparison of its activity was compared with BAP, a purinetype cytokinin. In the cultures of F. lyrata, TDZ in concentrations ranged from 0.01 to 0.02 mg/L could stimulate micropropagation. When the concentration of TDZ exceeded 0.2 ml/L, the shoots became somewhat malformed and vitrified in both species. Our result revealed that the cytokinin activity of TDZ in stimulation of shoot proliferation was higher than that of BAP in the cultures of F. benja-mina, but not in F. lyraia.
