香蕉寒害研究进展

寒害是我国香蕉生产最主要的自然灾害之一,我国大部分地区的香蕉常年都受其危害,造成大量的损失。解决香蕉的寒害问题,关键在于提高香蕉的抗寒力。综合有关文献,概述了20年来我国在香蕉寒害方面研究取得的主要进展,包括香蕉寒害症状及与寒害相关的气象指标和区划、香蕉寒害产生的机理及抗寒力指标、抗寒防寒栽培技术等。此外,就香蕉寒害研究存在的问题进行简单的阐述并对香蕉寒害未来的研究,特别是抗寒品种选育的研究进行展望。

Advances in research on chilling injury in banana

The banana chilling injury is one of the most principal natural disasters in our country. In a majority of banana producing regions a great deal of loss in common years in banana were resulted in by the chilling injury .In order to solve the problem, the linchpin is to increase the cold hardiness of banana. This paper synthesizes a lot of literatures, reviews the recent research progress in chilling injury in banana(Musa spp.)in the last 20 years. It includes the symptoms of banana chilling injury, the weather index and the agro-climatic delimitation which was correlated with banana chilling injury,the occurring mechanism of banana chilling injury, the index of cold resistance,the cold protection cultivating techniques etc. In addition, the problems in banana chilling injury research are simply discussed and the prospect of the future research on banana chilling injury, especially the breeding method of cold resistance cultivar in banana are discussed.
