| Abstract: | The effect of salinity stress on the germination rate of tree seed show that the two kinds of salts(NaCl and NaCl KCl) both have harmful influence on the seed germination as well as seedling growth. With the salinity concentration rising, the germination rates fall and the seedling growing worsen. Additionally compared with the compound salts ( NaCl KCl), single salt(NaCl) is stronger to hinder the seed germination and seedling growth, which indicates that K can alleviate the negative effect of Na . Finally, the concept of index of salinity tolerance is put forward. |
