4) rooting ability
生根能力
1.

提高杉木优良无性系插穗生根能力
2.
The rooting ability of rolB transformed clones of Populus tomentosa.;

3.
The cutting propagation trial was designed in 5 cutting length treatments which were 6 cm,9 cm,12 cm,15 cm and 18 cm respectively,aiming at revealing the correlation of the cutting length to three main technological factors such as rooting ability,survival rates of young plants and roots increment.
结果表明,不同插穗长度对箭胡毛杨生根能力、成活率和根生长量均有影响,但其中12、15、18 cm插穗长度间差异不显著。
5) rooting ability
生根力
1.
ABA content in stems increased with donor age,(IAA+GA+ZR)/ABA in stems decreased with donor age and the trend was similar to the change trend of rooting ability,the relationship between(IAA+GA+ZR)/ABA and rooting traits was significant,so(IAA+GA+ZR)/ABA could be used as an index of rooting ability.
结果表明:不同株龄插穗生根性状及插穗茎和叶中激素含量差异均达极显著水平,叶中激素含量对插穗生根力没有直接影响;插穗茎中生根抑制激素(ABA)含量随株龄增长而增加,生根促进激素与抑制激素的比值(IAA+GA+ZR)/ABA却随株龄的增长而递减,与生根力随株龄的变化趋势一致,且该比值与生根性状紧密相关,因此可作为评价母株(无性系)生根力的指标;插后13～32d是插穗愈伤组织形成和不定根诱导的关键期,此期生根促进激素消耗量大,茎中含量大幅度降低,进入根伸长生长阶段,含量上升;外源IBA促进插穗生根的机制在于通过外源激素的刺激,在不定根诱导期,插穗茎中ABA含量大幅度降低,从而有利于不定根的发生和发育。
