摘要: 通过爬山虎扦插繁殖研究,以梯度溶液NAA处理爬山虎嫩枝,温度和相对湿度分别保持在15~20℃和45%~49%,在总孔隙度为37.81%的纯沙基质1和总孔隙度为47.61%的沙土基质2上配合Hoagland营养液进行培养。培养3个月发现10-7NAA的溶液处理的爬山虎实验样品的成活率最高;新生根冠重量比例随NAA浓度的升高有缓慢降低的趋势;NAA浓度小于10-6时纯沙基质2比沙土基质1中爬山虎样品的成活率高,NAA浓度大于10-6时纯沙基质2比沙土基质1中爬山虎样品的成活率低。对爬山虎扦插繁殖的条件进行的初探,希望能供同类研究参考。

Abstract: According to the study of sticking and reproducing Parthenocissus Tricuspidata,sticking and reproducing primarily,using it’s young branches which are treated at 10-3、10-4、10-5、10-6、10-7、10-8 concentration NAA solution in series and living on different culture media with the gross cavity of 37.81% pure-sand and 47.61% mixed sand-soil.After culture in 3 months with Hoagland nutrition solution,it’s found that the samples treated at 10-7NAA has the highest surviving rate;there is the downtrend of the rate of new root-calyptra with the decline of NAA concentration;the surviving rate of pure-sand medium is higher than the surviving rate of mixed sand-soil medium when NAA concentration less than 10-6 ,and on the contrary when NAA concentration more than 10-6.This article reseaches the conditions of sticking and reproducing Parthenocissus Tricuspidata, and gives several pieces of advice which are shown of the enclosures for the peer’s reference.
