不同嫁接方法和生长调节剂处理与白玉芒嫁接成活率关系的研究

目的]研究嫁接方法与生长调节剂协同作用对白玉芒嫁接成活率的影响,为白玉芒种苗的繁育提供理论基础。方法]以海南本地芒一年生苗木作砧木,白玉芒一年生枝条作接穗,通过不同浓度的生长调节剂ABT(2505、001、000 mg/L)I、BA(501、002、00 mg/L)处理白玉芒的接穗,分别运用补片芽接和劈接两种嫁接方法进行嫁接处理。结果]在多种处理中,以ABT 500 mg/L劈接处理的嫁接成活率最高,达73.3%;以ABT 1 000 mg/L的芽接处理效果较好,达60.0%;以IBA 100 mg/L劈接处理的嫁接成活率较好。结论]上述生长调节剂与补片芽接和劈接两种嫁接方法组合的3种处理均与清水对照下相应方法的嫁接成活率差异显著,且方法操作简便易行,可在生产中推广应用。

Study on the Correlation between the Treatments with Different Grafting Methods and Growth Regulators and the Grafting Survival Rate of Baiyumang

Objective] The research aimed to study the effects of the synergistic action of grafting method and growth regulator on the grafting survival rate of Baiyumang and provide the theoretical foundation for breeding the seedlings of Baiyumang.Method] With one-year-old seedlings of local mango in Hainan as rootstock and one-year-old branches of Baiyumang as scions,the scions of Baiyumang were treated with different concn.of growth regulators ABT(250,500,1 000 mg/L)and IBA(50,100,200 mg/L) to make grafting by using 2 kinds of grafting methods including patch budding and cleft grafting.Result] Among all kinds of treatments,the grafting survival rate in the cleft grafting treatment with 500 mg/L ABT was highest(73.3%).The effect of bud grafting with 100 mg/L IBA was better(60.0%).The grafting survival rate in the cleft grafting treatment with 100mg/L IBA was better.Conclusion] The grafting survival rate in above 3 kinds of good treatments of combining the 2 kinds of growth regulators and 2 kinds of grafting methods including patch budding and cleft grafting had significant difference from that in control group with clean water by the corresponding method,which was simple to operate and could be popularized and applied in the production.
