补充资料:热带和亚热带果树
适宜于无霜冻或少发生霜冻的温暖地区生长的果树。主要分布在南纬30°至北纬30°之间。热带果树是常绿树,多数每年落叶一次,在季节改变时由新叶代替老叶。主要种类有椰子、香蕉、杧果、菠萝、棕枣、番木瓜、油梨、番荔枝、腰果等,对低温很敏感。亚热带果树中既有常绿的也有落叶的种类,生长在冬季比较寒冷但为期很短地区的,一般营养生长期较长。主要种类有柑橘、无花果、龙眼、荔枝、枇杷、杨梅、油橄榄、石榴等,其中有的稍耐霜冻。但二者的分类并不严格,各国的标准也不一致。由于引种驯化和育种工作的发展,现在不少果树的栽培分布已与自然分布或原产地有很大差别。如香蕉、菠萝等热带果树已在亚热带地区栽培生产,以致更难以严格区分。一般常将热带和亚热带果树相提并论。 这一大类果树在果树生产中有重要地位。如柑橘、香蕉、椰子的世界年产量仅次于温带果树的葡萄,经常分别居第 2、3、4位。果实除供生食外,也是制罐、蜜饯、香精油及其他加工工业的重要原料。中国的热带和亚热带果树的种质资源十分丰富,但除香蕉、菠萝和柑橘类少数几种果树外,其开发研究尚不及温带果树。
