油橄榄的适应性育种—实生选育和经济性状早期鉴定的研究

<正>本文介绍了适应性育种的方法和程序,并根据江苏省植物研究所油橄榄实生选择二十年的工作,提出了油橄榄适应性育种中抗寒性,丰产性和果实品质等三方面的选育指标,研讨了经济性状早期鉴定中的若干问题——叶片形态和电阻值的变化规律与抗寒性的关系,枝叶形态与耐涝性的关系,主干粗度和树冠结构与丰产的关系,叶形指数与果实品质指数的关系等,以便为提高选育效率提供依据。

ADAPTIVE SELECTION AND BREEDING OF OLIVES,A RESEARCH ON SEEDLING SELECTION WITH SPECIAL REFERENCE TO EARLY DETERMINATION AS REGARDS ITS ECONOMIC CHARACTERISTICS

Twenty years studies have been carried out on adaptive seedling selection of olives. In this paper, the process and method of selection are discussed. Selection indexes on cold resistance, productivity and fruit quality are raised. Correlations are studied between (l) leaf characters and frost resistance, (2) electric resistance of 1-year-old branches and frost resistance, (3) external characters of branches and leaves and water-logging resistance, (4) stem diameter and precocity, (5) leaf size and precocity, (6) leaf index and precocity, (7) stem diameter and productivity, (8) crown structure and productivity, (9) leaf index and fruit quality index, etc.
