摘要
为研究不同的碱盐溶液浓度对王不留行种子萌发的影响,试验使用不同浓度(20、40、60、80 mmol/L)的碳酸氢钠与碳酸钠混合碱盐溶液(摩尔比9∶1)胁迫处理,测定种子的发芽势、发芽率、发芽指数、简化活力指数等指标.结果发现,当混合溶液碱盐浓度为20 mmol/L时种子的发芽势、发芽率和发芽指数最高,随着碱盐浓度升高时种子萌发指标和简化活力指数相应降低.由此可知,王不留行对低浓度的碱盐溶液有一定的耐受性,高浓度的碱盐溶液则抑制种子萌发.
Abstract
In order to study the effect of different concentrations of alkali salt solutions on the germination of Semen Vaccariae seeds,experiments were conducted using different concentrations(20,40,60,80 mmol/L)of sodium bicarbonate and sodium carbonate mixed alkali salt solutions(molar ratio 9∶1)for stress treatment.The results of the measurements of germination potential,germination rate,germination index,simplified vitality index and other indicators of the seeds revealed that the highest germination potential,rate and index of the seeds were observed when the alkaline salt concentration of the mixed solution was 20 mmol/L.As the alkaline salt concentration increased,the germination index and simplified vitality index of seeds decreased accordingly.It can be inferred that Semen Vaccariae has a certain tolerance to low concentration alkaline salt solutions,while high concentration alkaline salt solutions inhibit seed germination.
