植物生长调节剂和扦插基质对紫椴嫩枝扦插生根的影响
Effect of Plant Growth Regulators and Cutting Medium on Rootingof the Tilia Amurensis by Softwood Cutting
摘要
Abstract
In order to screen a set of the cutting propagation technique and new substrate of promoting rooting rate in Tilia amurensis,the effects of plant growth regulators(IBA,ABT and NAA),their concentrations(500,1000,1500mg),and the substrate types(inorganic and organic substrate)on the quality of softwood rooting were studied.The results showed that the IBA had significant influence on its rooting rate of the best value 56% when quickly dipped the Tilia amurensis in IBA 1000mg for 15 seconds.The rooting rate of river sand was the highest in inorganic substrate with the rate up to 51%.The highest rooting rate in the organic substrate was No.21(peat and needle)with the rate up to 60%.关键词
