在60年代引进西孟加拉的香芽蕉无性系中,有‘Giant Governor’、‘Kabuli’和‘Robusta’等,其中以‘Giant Govern-or’得以普遍推广种植。品种的改变相应地带来了产量的提高,这是因为此品种不仅具有高产的潜力,而且又适于密植。然而,因品种布局发生了改变,病害问题亦随之而变化。近来在西孟加拉淤积地发生的一些新病害,例如由芭蕉尾孢菌(Cercospora musae)引发的叶斑病以及一种可能由病毒引发的束顶病的发病率正是由于香芽蕉无性系的栽种而有了提高。
In the 1960s, the introduction of the West Bengal sprout banana clones, there are ’Giant Governor’, ’Kabuli’ and ’Robusta’, etc., which ’Giant Govern-or’ to promote the general planting. The change in variety leads to a corresponding increase in yield as this variety not only has the potential of high yield, but also is suitable for close planting. However, due to changes in the distribution of varieties, disease problems have also changed. Recently some new diseases, such as leaf spot caused by Cercospora musae and a possible virus-induced bundle-roof disease, occurred in siltation in West Bengal precisely because of the And planting has improved.
