| 摘 要： | 以翅果油树(Elaeagnus mollis Diels.)当年生枝条为材料,对影响插穗生根的插穗规格、母树年龄、扦插时间、基质种类、激素种类及其处理时间等因素进行了系统研究.结果表明:翅果油树嫩枝扦插宜于6月下旬进行,将直径(d)和长度(l)分别为3mm＜d＜5mm和8cm＜l＜13cm的插穗扦插于蛭石和珍珠岩按1: 1(V/V)组成的复合基质中,扦插效果好,生根能力强;嫩枝插穗具有显著的位置效应和年龄效应,2年生母树中段插条制作的嫩枝插穗生根率为82%;外源激素处理是提高嫩枝插穗生根能力的一个必要措施,且以100和500mg·L-1的IBA分别处理240和1min的插穗生根效果最好.

| Abstract: | The soft branches of Elaeagnus molli were used as materials to study rooting ability of green-wood cutting.The effects of cutting scale,mother plant age,cutting date,type of culture medium,concentration and treating time of exogenous hormone,and cutting position on the rooting rate of cuttings were studied by randomized complete block design.Results indicated that the optimal date of green-wood cutting was late June,and the cuttings with a diameter of 3~5 mm and a length of 8~13 cm had a strong rooting abil... |
