[ Method] C. album seedlings grown to 6th leaf stage were conducted osmotic stress treatment with PEG6000 osmotic whose concentration was set up as 0, 5%, 10% and 20% and the various physiological indices of the 3rd -5th function leaves in upper plant were determined after being treated for 0, 1,3, 5, 7 and 9 d. [ Result] Under osmotic stress with 5% PGE, the relative water content （RWC） of C. album reduced less. Under osmotic stress with 10%, the RWC in seedling leaves of C. album decreased to 62% on the fifth day and the leaves began to wither. Under osmotic stress with 20%, the RWC in seedling leaves of C. album decreased to 61.9% on the third day and the leaves appeared withering, and the RWC decreased to 48.6% on the 7th day and the leaves were dry and yellow. Proline contents in seedling leaves of C. album under osmotic stress with 5%, 10% and 20% PEG were 7.64, 10.9 and 29.4 times of CK on the 7th day. [ Conclusion] C. album hed some adaptability to moderate osmotic stress, but the PEG osmotic stress with high concentration and long time might lead to severe damage on C. album.展开更多

In addition, the amylase activity was measured. The results showed that the four Canavium album Raeuseh cultivars were sensitive to NaCI stress in varying de- grees. When the NaCI concentration was less than 0.8%, the seed germination rates of the four Canavium album Raeuseh cultivars were all higher than 90%. However, with the increased NaCI concentration, the water intake by seed germina- tion was inhibited, the amylase activity was decreased, and the germination rate, germination index and vigor index were all trended to be decreased, which differed among the four test cultivars. When the NaCl concentration was less than 0.4%, the seedling growths of the four Canavium album Raeuseh cultivars were not af- fected. But when the NaCI concentration was increased, the critical salinities inhibit- ing radicle growth were different among the four cultivars （Huiyuan, 1.0%; Chayao No.1, 1.2%; Sanfang, 1.4%; Frantoio, 1.6%）. Among the four test cuttivars, the sen- sitivities to NaCl stress ranked as Huiyuan 〉 Chayao No.1 〉 Sanfang 〉 Frantoio.展开更多
