枸杞的扦插繁殖

PROPAGATION OF LYCIUM CHINENSE BY CUTTAGE

以细叶枸杞为试材 ,研究了枸杞的扦插繁殖。结果表明 :绿色嫩枝不宜作扦插材料 ,木质化、半木质化插条用2 0 0mg/kgNAA或IBA处理 30～ 6 0min或用 5 0 0mg/kgH3 BO3 处理 30min均可提高生根率和平均生根条数 ,但降低平均根长度。

Cuttage propagation of Chinese wolf-berry(Lycium chinense) was studied. The results showed that greenwood, cuttings, i.e. tender shoots with green leaves, were not suitable for cuttage propagation. Lignified or semi-lignified hardwood cuttings, treated with NAA or IBA at 200 mg/kg for 0.5～1.0 h., or with H 3BO 3 at 500 mg/kg for 0.5 h., rooted readily. The auxin treatments increased rooting rate and root number, but decreased root length.
