摘要
通过对6年生兴安落叶松、4年生长白落叶松和10年生杂种落叶松的嫩枝扦插试验证明,10年生杂种落叶松生根率最高达90％,在84种组合生根素中有7个组合生根率超过70％,并筛选出两种适宜嫩枝扦插的基质和1个最易生根的杂种优良无性系。
The experiments rooting of twig cuttings with 6 years old of Larix gmelinii, 4 year old of Laris__olgensis and 10 years old of some hybrids larch, enviroments and treatments are described which achieved good rooting results, The best rooting rate of hybrids at 10 years old larch can be reached to 90%, 7 compositions of rooting hormones for inducing rooting of twig cuttings grade over 70%, which accounts for 84 composition, Two composition of rooting medium have been selected, that is suitable for rooting of twig cutting, also one hybrid larch which is the easiest for rcoting has been discovered.
