| 摘 要： | 利用不同浓度的GGR6对南方红豆杉插穗进行处理,通过扦插成活率、生长量、生物量的调查和测定,结果为 流水对插穗进行前处理12 h后,用20 mg·L-1的GGR6溶液浸泡5 h,扦插后插穗成活率大幅度提高,分别高出相 同浓度的2,4-D和萘乙酸处理25.5％和16．2％,为空白对照的2倍。成活苗木的高度和粗度均高于其它处理。表 明用GGR6处理插穗能够提高红豆杉的扦插成活率,并可以促进高生长和径生长。用多菌灵提前处理插穗,能够降 低GGR6的作用效果。 |

| Abstract: | Investigation of survival rate and testing of increment and biomass of Taxus chinensis var. mairei seedlings by using cuttings treated with different concentrate of GGR6 showed that GGR6 could increase survival rate, height and diameter of seedling. While the cuttings were dipped in the GGR6 of 20 mg·L-1 for 5 hours after they were treated with water for 12 hours, the survival rate of the cuttings was 25. 5% and 16. 2% higher than the survival rate of cuttings treated by the same concentrate of 2,4-D and naphthylacetic acid, two times of the survival rate of seedling dipped in water. Both the height and diameter of the living seedlings treated with GGR6 were higher than that of other treatment. The result of this test also showed that it could reduce the effect of the GGR6 to dip quicksets in carbenazim before the quicksets were dipped in the GGR6. |
