摘要
试验以药效稳定的生长素IBA对草原樱桃根段进行扦插前处理 ,分析了药剂浓度、处理时间、处理部位对根插生根、发芽的影响。结果表明 ,生长素IBA对草原撄桃根插的生根率和发芽率都有显著的促进作用。不同IBA处理浓度对草原樱桃生根率无显著差异 ;对发芽率和平均生根数存在明显差异 ,IBA的浓度变化和处理时间与发芽率呈负相关 ,而与平均生根数呈正相关。IBA处理根段极性下端生根、发芽效果好。
In this experiment ground cherry root sections were treated with auxin IBA before root cutting, the rooting and budding effects of chemical concentration, treatment time and treatment position on root cutting were studied. The results indicated that there were no differences on rooting rate and significant differences on budding rate and average root number. IBA concentration and treatment times were negative correlation with Budding rate of root section and positive correlation with average root number. IBA treatment on the under side of root section is good for rooting and budding.
