| Abstract: |
| To further elucidate the mechanism of xylem pH as a root signal under drought stress,a study was conducted on relative water content,Proline content and Malondialdehyde content of Vicia faba leaves under different pH buffer treatments.The results showed that for leaves in vitro,relative water content was the highest under pH 6.5;Pro content was higher under acidic treatment;and Malondialdehyde content was the highest under pH 5.0 treatment.For the whole plant treatment,relative water content was the highest under 5 h pH 6.5 treatment,or 12 h under pH 5.0 treatment;Pro content was the highest under 5 h pH 5.5 treatment,but little change under 12 h treatment;Malondialdehyde content decreased a little under 5 h treatment,or did not change under 12 h treatment. |
