| Abstract: |
| In this study, we analyzed the cadmium（Cd）accumulation characteristics of different Cd-tolerant Lentinula edodes strains and the physiological changes in Lentinula edodes fruiting bodies at different developmental stages under Cd stress. As exogenous Cd stress was added, and Cd content changed, malondialdehyde（MDA）and soluble protein content in fruiting bodies at different developmental stages were explored. The results show that Cd stress affected the agronomic characteristics and yield of the fruiting bodies of the two strains, but different Cd tolerant strains were affected differently. The diameter and thickness of the cap of strain 4606 decreased significantly after Cd stress, but the other agronomic traits showed no significant difference. After Cd exposure to strain 4625, the number of fruiting bodies and the yield per rod decreased significantly, and the weight of a single mushroom and the weight of cap increased significantly. The Cd content in the fruiting bodies of unit dry mass of the two strains decreased significantly with the extension of growth and development time. After Cd stress, the MDA content of strain 4606 increased significantly in the growth period, decreased significantly in the mature period, and decreased extremely significantly in the parachute stage. The protein content of the 4606 strain control group and the Cd stress treatment group decreased significantly with a longer growth time, and that of the 4625 strain control group and the Cd stress treatment group increased significantly at first and then decreased significantly over time. The protein content of the 4606 strain at the open capillary stage was significantly reduced, but there were no significant difference in the other stages. In conclusion, the physiological responses of fruiting bodies to Cd stress of different Cd-tolerant strains of Lentinula edodes were different. Therefore, varieties with low Cd absorption should be selected for agricultural production. |
