| 摘 要： | 为了获得最佳的黑果枸杞优良种质资源的繁殖方法,对其不同繁育方式进行了探索。结果表明:实生繁育和嫩枝扦插是黑果枸杞成活率较高的繁育方式。条播、撒播、容器播种苗的出苗率差异不明显。1年生实生苗的移栽可有效促进侧根的伸长。嫩枝扦插用不同质量浓度(200、300、400、500、600 mg/L)的NAA与GGR处理插穗,最佳处理为GGR 500 mg/L,成活率为(84.00±9.17)%,平均新生枝长(5.13±1.57)cm,平均新生根长(2.85±0.94)cm。硬枝扦插效果不佳。

| Abstract: | In order to obtain the optimal propagation method of ifne germplasm resources inLycium ruthenicum, different breeding manners were researched. The results showed that seedling breeding and softwood cutting were the breeding way with higher survival rate ofL. ruthenicum. Seedling rates had no signiifcant differences among strip sowing, scatter sowing and container sowing. Transplanting one-year-old seedling could effectively promote lateral root elongating. In addition, effects of different mass concentrations of NAA and GGR solutions on softwood cutting were researched. 500 mg/L GGR treatment had the best effects, the survival rate was (84.00±9.17)%, the average length of new branch was (5.13±1.57) cm, and the average length of new root was (2.85±0.94) cm. The survival rate of hardwood cuttings was low. |
