摘要
用0.1,1,10,100,1000mg/L5种不同浓度的水杨酸(SA)浸种处理木槿种子,研究SA对木槿种子萌发及幼苗抗低温的影响。结果表明浓度为10mg/L和0.1mg/LSA处理,分别对木槿种子的发芽率和发芽势均有所提高,其余浓度则有抑制作用;SA处理后幼苗在2℃低温条件下可溶性蛋白含量和可溶性糖含量均提高,丙二醛(MDA)降低,说明SA处理可增强木槿幼苗的抗低温能力,且以10~100mg/L的处理效果较好。
The experiment studies the effects of SA on seeds germination and Anti-cold of Hibiscus syriacus Ls eedlings by using five different concentration(0.1,1,10,100,1000 mg/L)of Salicylic Acid(SA)to soakH ibiscus syriacus L Seeds.The results indicated that 10mg/L and 0.1mg/L SA improves the Hibiscus syriacus LS eeds germination rate(GR)and germination power(GP),but other concentration SA is prohibitive;the contento f proteins and the content of carbohydrate were increased,while content of MDA was declined in Hibiscuss yriacus L seedlings in 2℃.Result from cluster analysis shows that SA can enhance Anti-cold of Hibiscuss yriacus L Seedlings,and 10~100 mg/L SA is the best treatment.
