摘要
香蕉果皮组织可溶性糖随着香蕉采后后熟过程中，含量逐渐增加；但当果实出现明显病症时含量略有下降。多巴胺在香蕉采收时含量较高，但随着炭疽病发生明显下降。外源多巴胺在抑制芭蕉炭疽菌的同时也抑制了果实采后炭疽病的发生。对“黑油身”和“６３－１”两个抗性不同的品种分析表明，前者多巴胺含量较高、可溶性糖较低，与其较强的抗病性相一致。
The content of soluble sugars in banana(cv.“63 1”) peel increased gradually during ripening, but it decreased a little when the fruits showed obvious disease symptoms. The content of dopamine was higher at harvest (1 48 mg/g FW), and then decreased markedly during the incidence of anthracnose. The treatment with a concentration of 500 mg/L dopamine inhibited the development of anthracnose while exogenous dopamine suppressed the growth of Colletotrichum musae . Compared with the variety of “63 1”, the higher dopamine and the lower soluble sugars were observed in the variety of “Heiyoushen”, which was associated with a stronger resistance to the disease. A possible relationship between ocurrence of anthracnose and dopamine and soluble sugars of postharvest fruit of banana has been discussed.
