Cutting Propagation Test of Shoots of Sapindus mukorossi Gaertn

In order to solve the problem of rapid propagation of Sapindus mukorossi Gaertn seedlings, research on the cutting propagation of S. mukorossi Gaertn was conducted. The results showed that the rooting rate of cuttings of the ten clones ranged from 30.9% to 83.0%. Among them, the rooting rate of cuttings of clones SM01 and SM06 was higher than that of other clones, and there were significant differences between different clones in the rooting rate of cuttings. The rooting rate of the semi-lignified shoots having two leaves could be improved significantly. The treatment of the cuttings by GGR6 solutions had significant effects on their rooting rate.

无患子扦插繁殖技术研究

对插穗木质化程度、生根粉浓度和浸泡时间为主要因素的无患子扦插繁殖技术作了初步研究。结果表明:木质化插穗的根系最发达,生根数多;GGR浓度为200 ppm浸泡60分钟或ABT浓度400 ppm浸泡20分钟后能明显促进无患子插穗生根,成活率最高,成活率分别达到了91%和94%。

不同试剂处理对无患子扦插生根的影响

[目的]研究不同化学试剂、不同浓度和不同时间的处理对无患子扦插生根的影响。[方法]以无患子半木质化枝条为材料,研究ABT1号生根粉、吲哚丁酸在不同处理条件下无患子扦插生根和发育的影响。[结果]ABT1号生根粉处理后的效果要优于吲哚丁酸,在浓度为200 mg/kg,处理时间为3 h下生根率达到最高,为78.3%。而根的后续生长情况与试剂处理无明显联系。[结论]不同激素处理能促进根的萌发,但对根的生长无明显影响。

无患子的扦插研究

为了探索更优化的繁育技术,进行了无患子扦插繁殖试验.采用不同年龄、不同部位、不同生长调节剂、不同浓度处理无患子穗条按单因素试验设计进行扦插试验,调查成活率、生根率、生根数和根长度,计算根系指数和根系效果指数,并分析.结果表明:用800ppm生根粉处理过的无患子枝条梢部进行扦插,其生根率、生根数和平均根长效果最好,分别为33.33%、6.3根和48.6cm,根系效果指数达5.6.用无患子靠近顶芽的枝条作为插穗,有较好的成活率和生根率.
