荒漠区珍稀和野生果树的引种驯化

能在热带荒漠地区进行商业化栽培的作物种类是有限的,园艺作物尤其如是。本研究的目的就是通过引种驯化为热带荒漠区开发新品种。我们以下述两个来源的多年生植物为基础:干旱区和半干旱区人民食用的有营养价值的水果或干果的野生植物种;第二是从当地市场或栽培者那里能收集到的珍稀种类。以色列的内盖夫荒漠气候条件变幅宽广,水土类型多样,是本项研究的理想地点。本研究利用内盖夫的异质特点对向荒漠区引种驯化的不少植物的适宜性进行了预选试验。本文总结了从1984年开始的4年工作,并叙述了总的进展,详细介绍了六种预选植物。

Introduction and Domestication of Rare and Wild Fruit and Nut Trees for Desert Areas

The range of crops that can be grown commercially in hot desert regions is very limited. This is specially true for orchard erops. Our research program is to develop new crops for hot desert areas through introduction and domestication. Israel's Negev desert,with its broad spectrum of climatic conditions and types of soil and water, is an appropriate site for such a project. We have set out to exploit the Negev's variation to test the suitability of a number of plant candidates for introduction and domestication in desert areas. This is our first report on the project, and summarizes four years of work starting from 1984. We will describe our activities in general and give some details regarding six of our plant candidates.
