Abstract: Five 5.5-year-old hybrid families seedling ortets in larch nursery of Maojingba forest farm,Hebei Province,were used as regenerating materials in this experiment,the effect of IBA concentration and soaking time on rooting of semi-hardwood cuttings of hybrid larch and the response of different hybrid families to auxin treatment were systematically studied,and the genetic parameters of rooting under different auxin treatments were estimated. The results showed that suitable IBA treatment had an ob... More
