In this research, the fermentation broth produced from seven strains of endophytic fungi was sprayed on tomato plants at seedling stage. This process was carried out under Ca(NO3)2 stress, with comparison to the commercial microbial fertilizer to study the physiological and biochemical characteristics of tomato seedling. The results showed that most of the fermentation broths have no phytotoxicity and could improve salt resistance of tomato. The fermentation broth of strain Schizophyllum sp. DL12 displayed the best effects which increased the chlorophyll content (0.244 mg g−1 FW), soluble protein (31.48 µg g−1 FW), proline content (305.6 µg g−1 FW), peroxidase (21.78 µg g−1 FW min−1) and catalase (0.345 µg g−1 FW min−1) activities in leaves significantly as compared with control (CK) and commercial microbial fertilizer. These findings indicated that fermentation broth of Schizophyllum sp. DL12 has bright prospects of applications.
