摘要
楸树（Catalpabungei C．A．Mey．）为紫蒇科（Bignoniaceae）梓属（Catalpa Scop．）落叶乔木，生长速度快，其树干通直、材质坚韧，既可观花又能观果，是优质用材、行道树和园林观赏的常用树种之一。近年来，研究者对楸树的耐盐性、品种选育以及繁殖技术等进行研究并获得了一定的成果阻。
Abstract： Sprouting capability of two-year-old branches from 28 clones of Catalpa bungei C. A. Mey. were compared, and sprouting capability of C. bungei ＇Jinsi＇ branch with different diameters and effects of bed temperature and room temperature on sprouting capability of C. bungei branch were analyzed. The results show that sprouting capability of C. bungei and C. bungei ＇ Jinsi＇ branches are higher with the values of 6.4 and 5.8, respectively. Sprouting capability of C. bungei ＇ Sanlie＇ , C. bungei ＇ Xinye＇ and C. bungei ＇ Changguo＇ branches are lower with the values of 1. O, 1.3 and 1.4, respectively. The branch sprouting capability relates to branch diameter, temperature, relative humidity and sprouting time. The suitable sprouting condition of C. bungei branch is preliminarily confirmed, that is, branches with diameter above 1.5 cm under bed temperature 15 ℃ -20 ℃, room temperature 20 ℃-25 ℃ and relative humidity about 70% sprout for 50 d.
