番木瓜试管苗生根的研究进展

Research progress of test-tube seedling rooting in papaya

试管苗诱导生根培养是番木瓜组织培养的关键技术。不定根的数量和质量是试管苗成功驯化的关键性因素。通过查阅文献,总结了国内外近几十年来番木瓜组织培养中不定根诱导的研究进展,主要从品种差异、外植体来源、培养基、植物生长调节物质、培养程序等方面进行综述,并对其进一步的研究方向进行展望,旨在为番木瓜组培生根技术的深入研究提供一些策略和思路。

Inducing root culture of test-tube seedlings is the key technique of tissue culture of papaya.The quantity and quality of adventitious roots are the key factors for successful domestication of test-tube seedlings.In this paper,the research progress of adventitious root induction in tissue culture of papaya in recent decades was summarized from the aspects of variety differences,source of explants,medium,plant hormones,culture procedures and so on,and the future research direction was prospected,in order to provide some strategies and ideas for further research on tissue culture rooting techniques of papaya.
