ABT处理和插穗长度对栝楼扦插苗质量的影响

栝楼是雌雄异株植物，在人工栽培过程中，扦插快繁技术能有效控制雌雄株合适比例；本试验研究了ABT不同浓度（0mg/l、50 mg/l、100 mg/l和200 mg/l）、100 mg/l浓度时不同浸泡时间（10min、20 min、40 min和60 min）和不同插穗长度（1节、2节和3节）对扦插生根率和移栽成活率的影响。实验结果表明：在用珍珠岩做基质时，栝楼扦插快繁适合的条件是：选用当年生的2节插穗，用100mg/l浓度的ABT粉浸泡40分钟；该处理条件下，插穗具有100%的生根率和99%的移栽成活率以及较好的综合经济效益

The effects of different ABT treatment and length of cuttings on the quality of trichosanthes cutting seedlings

In order to effectively utilize cutting technology for producing high-quality Trichosanthes seedlings and controlling an appropriate proportion of male and female plants, the study examined the effects of different ABT concentration （0 mg/L, 50 mg/L, 100 mg/L and 200 mg/L）, different soaking time under 100 mg/L ABT（10 min, 20 min, 40 min and 60 min） and different cuttings length （1 node, 2 nodes and 3 nodes） on cuttings rooting rates and transplant surviving rate. The results show that： When using perlite as matrix, the optimum condition of cuttings propagation is selecting one-year branchs with 2 nodes as cuttings and soaking them with 100 mg/L ABT for 40 minutes, under which, the 100% rooting rates of cuttings and 99% transplant surviving rate of seedlings were obtained.
