1) matermal stock age
母株龄
2) stock age
母株年龄
1.
The results indicated that the cutting propagation media,stock ages and planting time had obvious affection on rooting rate and root increment of Phoebe bournei,but different concentrations of rooting reagents had no obvious affection on rooting rate and root increment of Phoebe bournei.
结果表明:扦插基质、母株年龄、扦插时间对闽楠生根率及根生长影响显著,不同生根促进剂浓度对生根率及根生长无显著影响;各因素的最佳组合为:1年生母株穗条经ABT1#800 mg。
3) donor age
株龄
1.
The relations among donor ages,endogenous hormone contents and rooting,and the positive effects of exogenous IBA on hormone contents and rooting of Larix kaempferi cuttings were studied.
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。
4) maternal plants
母株
1.
The results showed that the quality of the maternal plants with 2 years old that had been cultivated in the three different nutrition levels had significant difference.
油松扦插繁殖时,在采穗母株年龄、插穗枝条年龄、扦插方法均相同的情况下,存在成活率不稳定的现象。
5) plant age
植株年龄
1.

产地和植株年龄对苦参干燥根中氧化苦参碱含量的影响(英文)
6) Old plant
