引言在树木育种工作中,人们已将辐射技术用于诱导突变,改良对病虫的抗性。同位素示踪技术也已经用于优良植物基因型的选择和评价。虽然赞比亚野生的、多种用途的林木果树具有很大的生产潜力,但它们也有其本身所固有的一些缺点,如生长缓慢,果实中果肉百分率低以及易生虫和感染病原菌。我们这次试验是赞比亚首次将辐射诱变技术应用于改良林木的一些不良性状。这份报告报道了 Uapaca kirkiana 树生长表现的早期观察 Introduction In tree breeding efforts, radiation technology has been used to induce mutations and improve resistance to pests and diseases. Isotope tracing techniques have also been used for the selection and evaluation of good plant genotypes. Although the wild, multi-purpose forest trees in Zambia have great potential for production, they also have some inherent disadvantages such as slow growth, low percentage of fruit in the fruit, and susceptible and pathogenic bacteria. Our experiment is the first time that Zambia has applied radiation-induced mutagenesis to some undesirable traits of improved trees. This report reports early observations of the growth performance of Uapaca kirkiana trees
