| 摘 要： | 采用60℃20s热水喷淋处理(HWRB)、拮抗菌(罗伦隐球酵母)浸泡处理(108个细胞/mL的孢子悬浮液)及2者结合处理先锋樱桃果实,研究各处理对果实常温贮藏5d后的自然发病率、腐烂指数和感官品质及对接种扩展青霉或灰葡萄孢霉后果实伤口的发病率和病斑直径的影响。结果表明,HWRB处理能显著抑制果实的自然发病率及腐烂程度,拮抗菌的效果次之,而结合处理的抑制效果最好;各处理均未影响果实的品质。对接种扩展青霉的果实,结合处理能够有效减少伤口94%的腐烂和病斑直径的扩大,且效果好于HWRB及拮抗菌单独处理;对接种灰葡萄孢霉的果实,拮抗菌能够显著抑制伤口的发病率和病斑直径,而HWRB处理则能完全抑制伤口的发病,结合处理并未带来更好的效果。总之,HWRB处理结合拮抗菌能够成为一种理想的控制樱桃果实采后腐烂的处理方法。

| Abstract: | The effects of HWRB (hot water rinsing and brushing) treatment, yeast antagonist dipping (Cryptococcus laurentii, 108 cells per mL), alone and in combinations, for the control of natural infections, and its effects on postharvest quality after 5 days' ambient temperature storage and control of inoculation with Penicillium expansum and Botrytis cinerea rot on harvested Van sweet cherry were tested. Results showed that HWRB treatment alone or in combination with yeast antagonist could significantly inhibit fruit natural decay incidence and severity, and the combination treatment of HWRB with the application of yeast antagonist had the best inhibiting effect; HWRB and yeast antagonist treatment applied separately or in combination did not affect fruit quality after storage. The combination treatment gave 94% decay inhibition and also reduced wound lesion diameter of fruit inoculated with Penicillium expansum, more effectively than HWRB or yeast antagonist treatment alone. However, yeast antagonist application alone could significantly decrease wound decay development and lesion diameter of fruit inoculated with Botrytis cinerea, while HWRB treatment alone completely inhibited wound decay caused by Botrytis cinerea, and the combination treatment showed no additional effect. Overall, the combination of HWRB and yeast antagonist treatment could be an ideal alternative to chemicals for the control of postharvest decay of sweet cherries. |
