Effects of Mediums on New Shoot Growth and Root Development for Hardwood Cuttings from Malus prunifolia
摘要
Abstract
Using annual branches selected from Malus prunifolia as materials, the effects of river sand, mixed substrate(turfy∶perlite∶vermiculite = 2∶2∶1) and turfy soil as mediums on new shoot growth and root development were studied by hardwood cuttings technology in the study. The results showed that in the three kinds of mediums, the new shoots began to germinate from the second week, and the basal callus developed from the third week. The turfy soil as medium had the best cuttage effect, and the mixed substrate was next. The numbers, length, diameter and fresh weight of new shoots from Malus prunifolia reached the maximum with the turfy soil treatment at the fifth week, and their mean values were 3. 67, 49. 54 mm, 2. 02 mm and 1. 2 g. The numbers, length and diameter of the new roots also showed the best performance in turfy soil at the fifth week, and the mean values were 37. 00, 32. 09 mm and 1. 33 mm. At the fifth week, the fresh weight of the new shoots and the numbers, length and diameter of the new roots reached a very significant level respectively compared with the other two kinds of mediums, but the other indexes had no significant differences.关键词
