摘要
以大樱桃＂吉塞拉＂为试材,研究了IBA对大樱桃试管苗生根的效应关系。结果表明：（1）IBA对大樱桃生根的静态指标（平均根长、分化率与生根系数）与动态指标（分化速度与增殖速度）的效应均极其显著（P〈0.01）;（2）随着IBA浓度的增加大樱桃生根各指标呈现先升高后降低的趋势,各指标二次回归曲线趋势近似相同。经回归分析,当IBA的添加量分别在1.3791~1.4231 mg/L与1.2931~1.4239 mg/L之间,大樱桃＂吉塞拉＂5号与6号可以获得较好的生根效果。
Using Gisela as experimental materials, the effect of IBA on rooting of in vitro cherry were re- searched. The results showed that： （1） IBA had significant influence on static index of average length, differentiation ratio and rooting coefficient and dynamic index of differentiation speed and regeneration speed of Gisela （P〈0.01）; （2） The root Indexes increased firstly and decreased subsequently with the concentration of IBA increased and the trend of quadratic regression equations was similar. Through regression analysis, rooting in vitro ＇Gesila 5＇ and ＇Gesila 6＇ was better when the concentration of IBA was 1.3791 ~ 1.4231 mg/L and 1.2931 ~ 1.4239 mg/L, respec- tively.
