栒子扦插繁殖研究

Study on Cutting Propagation of Cotoneaster tibeticus Klotz

以栒子为试材,研究了50、100、200、300mg/L 4种浓度的ABT-1号和NAA对当年生半木质化的栒子枝条生根率、生根长度和生根粗度等指标的影响,以期探讨ABT-1号和NAA对嫩枝扦插繁殖效果。结果表明:2种生长素均可促进枝条生根,其中200mg/L ABT-1号和NAA溶液处理的效果最好,生根率分别达到90.5%、87.8%,生根长度分别达到3.52、3.48cm,生根粗度分别达到0.25、0.24cm。

Taking Cotoneaster tibeticus Klotz as test materials,effects of 50,100,200,300mg/L four concentrations of ABT-1and NAA on rooting rate,root length and root coarseness and other indicators of current-year numbers and semi-woody branches of Cotoneaster tibeticus Klotz were studied,in order to research ABT-1and NAA reproductive impact on softwood cuttings.The results showed that two kinds of growth hormone could promote rooting branches,which the effect of number 200mg/L ABT-1and NAA were the best solution treatment,rooting rate reached 90.5%,87.8%,root length reached 3.52 cm,3.48 cm,rooting roughness reached 0.25 cm,0.24 cm.
