本试验致力于研究一些果树和砧木硬枝插条的愈伤和生根问题。全部工作是在河北农业大学温室中,并在弥雾条件下进行的。对以下几方面进行了研究:IBA、IAA、NAA 和2,4—D对插条愈伤和生根的影响,芽萌发与生根的关系,环境因子对生根的影响。结果认为,许多种材料有生根反应,但其中猕猴桃、文冠果和毛樱桃可分别达到40%、56.7%和64.7%的生根率。葡萄很明显是成功的。 This experiment is devoted to the callus and rooting of some hardwood cuttings of fruit trees and rootstocks. All work is in the greenhouse of Hebei Agricultural University, and carried out under misting conditions. The effects of IBA, IAA, NAA and 2,4-D on calli callus and rooting, the relationship between bud germination and rooting, and the effects of environmental factors on rooting were studied. The results showed that many kinds of materials had rooting reaction, but the kiwifruit, the fruit of Xanthoceras sorbifolia and the cherry could achieve the rooting rates of 40%, 56.7% and 64.7% respectively. Grapes are obviously successful.
