Effects of SNP and Zn2+ on the Growth of Cotton Seedling under Salt Stress Conditions
To research the effects of soaking seeds using compound of SNP (NO donor) and Zn2+ on the cotton(Gossypium spp.) seedling growth under salt stress,taking Lu 21 as materials,the effects of compound of SNP and Zn2+ on germination rate, germination potential,seedling leaf conductivity,root activity,POD activity,SOD activity,chlorophyll content,proline content and MDA content of cotton under salt stress were studied. The results showed that,under salt stress conditions,SNP and Zn2+compounds could significantly improve the germination rate,germination potential,root activity,POD activity,SOD activity, chlorophyll and proline content of cotton seed,and reduce the conductivity and MDA content of seedling leaves. The com-pounds of 0.10 mmol/L SNP and 20 mg/L Zn2+ had the best effect.
