| 摘 要： | 介绍了青海云杉硬枝扦插插穗生根的三种类型,主要研究IBA(吲哚-3丁酸)的不同浓度和不同处理时 间对青海云杉硬枝插穗生根的影响,以及不同单株间插穗生根情况的差异。比较了IBA对青海云杉1年生硬 枝进行不同处理的生根差异、萌芽情况和插穗腐烂情况,找出了较好的促进青海云杉插穗产生更多高质量根 的．IBA浓度和处理时间的组合(IBA 250 mg·kg-1处理12 h);并且对IBA不同浓度,不同处理时间与插穗生 根之间的关系以及衡量扦插效果的不同指标间相关性均进行了分析,讨论了在IBA处理下插穗上部芽的萌发 与插穗生根之间的关系。 |

| Abstract: | Three rooting types of Picea crassifolia hardwood cutting were introduced. The influence of IBA( Indole 3-butyric acid) with various concentrations and treatment time on its rooting and the difference in rooting among individual cuttings were studied. The rooting, sprouting and cutting rot of one-year-old P. crassifolia hardwood cutting treated with IBA were compared and the optimal combination of IBA concentration and treatment time ( IBA 250 mg. kg-1, treatment time 12 hours) ,which could promote P. crassifolia hardwood cutting to produce more and better roots, were determined. The relationship between treatment time and rooting of hardwood cutting and the correlation of indexes measuring the rooting efficiency were analyzed. Also,the relationship between the budbreak of the apical buds and rooting of cutting of cutting were discussed. |
| Keywords: | Picea crassifolia hardwood cutting IBA (Indole 3-butyric acid) |
