雅思听力此前也考查到过关于某种植物或水果，比如香蕉的种植和栽培，这样的部分，大部分都是大家比较熟悉的事物，但这次考查的passion fruit究竟为何物，很多同学一点概念都没有，英汉词典的解释为西番莲果，西番莲的一种可食果实。好像还不是能够比较全面的了解这究竟是个什么东东。笔者查阅了大量的原版外文资料，总结了一下passion fruit的方方面面。 Common Names: Passion Fruit, Granadilla, Purple Granadilla, Yellow Passion Fruit The passionfruit is a vigorous, shallow rooted, perennial vine that climbs by means of tendrils. There are two types of passionfruit. They are the yellow passionfruit which is suited to tropical conditions, and the purple passionfruit which grows best under sub-tropical conditions. The yellow passionfruit is tolerant to most of the soil borne pests and diseases that affectthe purple type, and is more prolific, bearing larger, heavier fruit with more juice, which has a higher acid content than the purpletype. The flavour of the purple type is preferred over that of the yellow type. Origin: The purple passion fruit is native from southern Brazil through Paraguay to northern Argentina. It has been stated that the yellow form is of unknown origin, or perhaps native to the Amazon region of Brazil, or is a hybridbetween P. edulis and P. ligularis . Cytological studies have not borne out the hybrid theory. In Australia the purple passion fruit was flourishing and partially naturalized in coastal areas of Queensland before 1900. In Hawaii, seeds of the purple passion fruit, brought from Australia, were first planted in 1880 and the vine came to be popular in home gardens. |
