摘要
采用L16(44×23)正交试验的方法研究了激素、激素浓度、处理时间和枝条部位等因素对兔眼蓝浆果2个品种绿枝插穗生根的影响。结果表明:影响兔眼蓝浆果插穗生根的主导因素是枝条部位,其次是品种和激素种类,激素浓度的影响最小;枝条上部的插穗生根率和生根数极显著优于中、下部,上部平均根长极显著高于下部;‘园蓝’(‘Gardenblue’)的生根率和平均根长显著高于‘灿烂’(‘Brightweel’),2个品种的生根数差异达极显著水平;激素GRR处理的插穗生根较好。兔眼蓝浆果绿枝扦插的最佳处理组合为:插穗选用‘园蓝’枝条上部,在激素GRR 100 mL.L-1中处理1 s,扦插生根率达92.31%。
Factors influencing the rooting ability of Vacciniurn ashei cuttings were investigated by means of orthogonal test （44 × 23）. The results showed that brachches position was the main factor then were varietys of the blueberry and type of hormone. Hormone concentration had the least impact on rooting. The rooting rates and average root lengths with top part of branch were significantly higher than those with middle and lower parts of branchs. The rooting rate and average root length of ‘Gardenblue＇were significantly higher than those of ‘Brightweel＇,and the difference reached most significant level. GRR treatment was suitable to cutting rooting. The optimal treatment was that selecting top branch of ‘Gardenblue’ as cutting, treating with 100 mL·L^-1 GRR 1 s, and the rooting rate of cuttings reached 92.31%.
