近年来,植物组织培养已取得很大进展。利用自发或人工诱发的遗传变异是组织培养的主要目标。细胞培养技术为在大的细胞群中选择突变体提供了新的可能。本文描述了在愈伤组织生长期间诱发的四种突变,并证明早抽穗、白化、矮秆和不育这四种突变是按顺序独立诱发的。 In recent years, great progress has been made in plant tissue culture. The use of spontaneous or artificial induced genetic variation is the main goal of tissue culture. Cell culture techniques offer new possibilities for selecting mutants in large cell populations. This paper describes four mutations induced during callus growth and demonstrates that four mutations, early heading, albino, dwarf and infertility, are independently induced sequentially.
