枫杨秋季扦插繁殖技术的研究
|
摘要
为了研究秋季不同的处理方法对枫杨硬枝和嫩枝扦插生根的影响以及扦插生根与插穗内营养物质含量之间的关系,分别以枫杨的硬枝和嫩枝为实验材料,从3种不同种类的外源生长调节剂及浓度等方面研究了不同处理分别对硬枝和嫩枝生根的影响,同时测定了枫杨扦插不同时期的可溶性糖和可溶性蛋白质的含量。结果表明:枫杨硬枝的扦插成活率高于嫩枝,其中最适合硬枝扦插的外源生长调节剂为IBA+ABT2 000 mg/L,生根率高达94.22%,生根效果指数为15.11;最适合嫩枝扦插的外源生长调节剂为GGR1 000 mg/L,生根率为48.20%,生根效果指数为2.81。枫杨硬枝和嫩枝扦插都是以皮部生根为主。生根过程中插穗基部的可溶性糖含量先急剧下降后缓慢升高,蛋白质含量变化趋势总体呈下降—升高。
In order to study the effects of different treatments on the rooting of hardwood and twig of Pterocarya stenoptera C. DC in autumn, and the relationship between rooting and nutrient content in cuttings, the hardwoods and twig of Pterocarya stenoptera C. DC were used as experimental materials. The effects of different treatments on hardwood and softwood were studied in different types of external growth regulators and concentrations. The contents of soluble sugar and protein in different stages of Pterocarya stenoptera C. DC cuttings were also determined. The results showed that the rooting rate of hardwood cuttings was higher than that softwood. The most suitable external growth regulator for hardwood cuttings was IBA+ABT2 000 mg/L, and the rooting rate was as high as 94.22%and the rooting effect index was 15.11. The most suitable external growth regulator for softwood was GGR1 000 mg/L, the rooting rate was 48.20%, and the rooting effect index was 2.81. The hardwood and softwood are mainly rooted in the skin. During the rooting process, the soluble sugar content in the base of the cuttings decreased sharply and then increased slowly, and the trend of protein content decreased and increased.
