LED光质对植物组织培养影响研究进展

Application of light-emitting diodes(LEDs) in in vitro plant tissue culture:A review

发光二极管(LED)作为一种比传统光源更为有效的替代光源,越来越多地被应用于植物组织培养中。近年来学者围绕LED光源在植物组织培养中的应用进行了大量的研究,并已证明植物组织培养过程的各个阶段均受到LED光质的调控。该文就LED光质调控植物组织培养的研究现状进行概述,重点介绍了LED光质对植物愈伤组织的诱导和分化、组织培养苗增殖、生长发育和生根壮苗等方面的影响,并对今后LED光质调控的研究进行了展望。

As a new and effective lighting systems,light-emitting diodes（ LEDs） has been extensively used in plant tissue culture.To investigate effects of LEDs on plants,lots of studies have been conducted,which has proved that various stages of plants grown in vitro have been regulated by light quality of LEDs. This article gives an review of the effects of light quality of LEDs on the growth and differentiation of plant callus,seedlings multiplication,the growth and development of plants and rooting in vitro,and also describes the prospects of the study on light quality of LED in the future.
