马铃薯剪枝扦插是扩大繁殖脱毒种薯的一项重要技术,一株试管脱毒苗假植成活后可以连续剪取两三个枝条进行扦插繁殖。我们应用ABT生根粉在马铃薯剪枝扦插中进行试验,达到生根快,生根多、根势强的目的。 1、材料和方法品种为紫花白,剪取试管苗假植后50天的顶部嫩枝,留2—3个小叶片。由《山西农业科学》编辑部提供ABT3号生根粉。将3号生根粉首先在酒精中溶解开,用自来水配成50ppm的溶液。
Potato pruning is an important technology to expand the propagation of virus-free seed tubers, a test-tube virus-free seedlings survive after planting can cut two or three consecutive cuttings for cutting propagation. We use ABT rooting powder in potato pruning cutting trials to achieve rapid rooting, rooting, root strong purpose. 1, Materials and methods Variety of purple white, cut the top shoots of test tube seedlings after 50 days of planting, leaving 2-3 small leaves. By the “Shanxi Agricultural Sciences” editorial ABT3 No. rooting powder. The 3 rooting powder first dissolved in alcohol, dubbed 50ppm solution with tap water.
