Abstract
BACKGROUND: Botrytis cinerea and Rhizopus stolonifer, two main postharvest pathogens, cause great loss of strawberry fruits.Here, the effects of poplar buds extracts, a main plant source for Chinese propolis, on disease control were investigated in vitro and in vivo.
RESULTS: The HPLC profile of poplar buds ethanol extract (PBEE) was almost identical to that of propolis ethanol extract (PEE),with the active flavonoids identified as pinocembrin, chrysin and galangin. PBEE exhibited similar inhibitory activities on spore germination of both pathogens compared with PEE, and PBEE also strongly inhibited the mycelial growth of the pathogens. In vivo, PBEE could effectively reduce decay of strawberry fruits stored at 13 °C. Although the weight loss was slightly increased, the contents of total soluble solid, titritable acid, vitamin C and total anthocyanins were significantly higher in PBEE treated fruits than those of the control.
CONCLUSION: PBEE had the similar antifungal activity with propolis and had great potential as an alternative to propolis to control strawberry fruits diseases.
Keywords: strawberry; poplar buds; propolis; antifungal activity; postharvest diseases

摘要:杨树芽作为蜂胶替代物对草莓果实采后病害控制的效应灰霉菌和根霉菌是草莓果实两大主要采后病害真菌,给生产带来很大损失。中国蜂胶的胶原植物杨树芽提取物,对草莓果实病害的离体和活体控制效果进行了研究。结果表明,杨树芽的乙醇提取物和HPLC图谱几乎与蜂胶乙醇提取物完全相同,均含有松鼠素、白杨素和高良姜素。杨树芽提取物对两病原菌孢子萌发表现的抑制活性与蜂胶提取物相似,且能强烈抑制两种真菌菌丝生长。活体结果表明,杨树芽提取物能有效减少草果果实在13度下的腐烂。尽管处理轻微增加了果实失重,但可溶性固形物、可滴定酸、Vc、总花色苷含量显著高于对照果实。结论:杨树芽提取物有与蜂胶相似的抗真菌活性,可以作为蜂胶替代物在控制草莓病害中应用。
