铈元素和阿斯匹林对棉花老化种子发芽的影响

Effects of Ce(NO_3)_3 and Aspirin on the Germination of Aged Cotton Seed

用不同浓度的Ce(NO3) 3和阿斯匹林 (Asp .)复配后对棉花老化种子进行处理 ,结果表明 ,一定浓度的Ce(NO3) 3和Asp .能够明显提高棉花老化种子的发芽率、发芽指数、活力指数、幼苗长度 ,并降低其相对电导率 ,但二者互作效果没有达到显著水平 ,其中以 1 0 μg/mlCe(NO3) 3+ 60mg/LAsp .复配处理效果最好。

Treatments on aged cotton seed with different combination of Ce(NO 3) 3 and Aspirin(Asp.) showed that the suitable concentration of Ce(NO 3) 3 and Asp.could improve some characteristics of aged cotton seed such as germination percentage,germination index,vigour index and the length of seedling,and decrease it's relative conductance of the solution of soaking seeding.Though their interaction effects were not significant among all the treatments,the combination of 10μg/ml Ce(NO 3) 3 and 60 mg/L Asp.was the best.
