一、前言目前我国油橄榄引种驯化工作,在大规模引种、栽培的基础上,应加速新品种的选育工作,以培育出适应我国气候特点的地方品种,使引种驯化任务,早日完成。 1964年从阿尔巴尼亚大批引入的苗木,至1970年前后,都已开花结实;结实种子起源的第二代苗木,又已开花结实。由于引进品种间、或同一品种不同个体间遗传性上存在很大差异,再加上我国气候条件不同,反应是不同的,分化是剧烈的。在一般当中尚不乏个别珍贵植株;它们枝叶繁茂、结实可观,增产幅度有逐年上升之势。而生长差的,十多年来 I. Introduction At present, on the basis of large-scale introduction and cultivation, the introduction and domestication of Olive in China should speed up the breeding of new varieties to cultivate local varieties that adapt to the climatic characteristics of our country so as to complete the task of introduction and domestication as soon as possible. The seedlings introduced in large quantities from Albania in 1964 have flowered before and after 1970; the second-generation seedlings, which are of strong seed origin, have flowered again. Due to the introduction of species, or the same species of different individuals there is a large genetic differences, coupled with the different climatic conditions in our country, the reaction is different, the differentiation is dramatic. In general, there is no shortage of individual precious plants; they lush foliage, strong and substantial, the rate of increase has been rising year by year. Poor growth, more than a decade
