When concentrations of polyethylene glycol(PEG)raised to 15%,germination speed,germination exponent,vitality exponent,sprout length decreased in diffent extent.
结果表明 :随着水势的下降 ,其发芽率在轻度水分胁迫下有所上升 ,然后降低 ,随 PEG浓度上升到 15 %时 ,发芽率、发芽速度、发芽指数、活力指数、芽长等都出现不同程度的降低。
This paper expounds the process and method of the germination test of the seeds of gleditia sinenssis, and draws a conclusion that the germination speed of the seeds treated with concentrated sulphuric acid for 40 min is higher, the germinating capacity of the seeds marinated in high-temperature water is higher, and the geminating capacity of the seeds accelerated in heat zone is high.
阐述了皂荚种子发芽试验的过程及试验方法,得出40min浓硫酸处理种子发芽速度快、高温水浸种发芽率较高、高温层积催芽发芽率高的结论。
The result showed that as water potential decreased,germination percentage,speed of germination,germination index,vigor index,sprout length,roots length,R/S(ratio of root to shoot),fresh and dry weight of plant decreased in different extent.
结果表明,随着水势的下降,发芽率、发芽速度、发芽指数、苗高、根长、根茎比、幼苗干、鲜重等都出现不同程度的降低。
The germination rate,germination capacity and mean germination speed of Hippophae rhamnoides seeds were obviously improved after the seeds were soaked with different concentrations of the natural brassinolide (NBR).
用不同质量浓度的天然油菜素内酯 (NBR)处理贮藏 4年的沙棘种子后 ,发现天然油菜素内酯对沙棘种子的发芽率、发芽势及平均发芽速度有明显的促进作用。
The effect of C19 supernatant on the germination rate of cucumber seeds was studied, the result showed that 100 × dilution improved the germination rate of cucumber seed significantly.
制备产嗜铁素细菌C19的培养液,并稀释成10倍,100倍,1000倍液浸种黄瓜种子,观察测算其发芽速率,结果表明100倍的菌夜处理后黄瓜种子发芽率最高,同时能较明显促进芽的生长。
