摘要： This study investigated the effectiveness of Bletilla striata polysaccharide (BSP) in inhibiting Botrytis cinerea (B. cinerea) growth and maintaining postharvest quality of 'Red Globe' grapes. The research revealed that BSP at a concentration of 20 mg mL-1 exhibited significant inhibitory effects on the mycelial growth, spore germination, and germ tube elongation of B. cinerea. BSP treatments substantially enhanced the activities of key resistance-related enzymes, and led to increased levels of total phenolics and flavonoids, thereby improving the disease resistance of fruit. The application of a BSP coating film proved effective in mitigating decay and maintaining the overall quality of 'Red Globe' grapes during storage. These findings collectively demonstrate BSP's potential as a promising agent for suppressing B. cinerea growth, enhancing fruit quality, and managing postharvest diseases in grape.
