| Abstract: |
| The effects of NaCl stress on germination of Isatis indigotica Fort.seeds were studied by culturing them in culture dishes.The result showed that the germination percentage,germination energy,germination index(GI),viability index(VI) decreased with the increasing of NaCl concentration stress.The growth of seedling treated with NaCl concentration indicated that praline content,MDA content and the cytoplasm increased remarkably with the increasing of NaCl concentration,but the radical length,hypocotyl length,fresh weight of radical,hypocotyl and cotyledon decreased. |
