光谱与光密度影响马铃薯试管薯诱导发育的研究进展
Study on the growth and development of potato microtuber by light intensity and light quality
摘要
Abstract
Potato mirco-tuberization is a key technology applied in building modern seed industry of virus-free seed potatoes factory production. However,the technology is subjected to the low quality of microtuber induction and the small individual quality. The development of in vitro microtuber includes the three stages of strong plantlets culture in rooting,microtuber induction and expansion, and is controlled by the factors such as genetype,physical environment and exogenous hormones and so on. As physical environmental factors,light drives plant life activity,light intensity and light spectral play a vital role in regulating the microtuber induction,matter accumulation of expansion and photosynthate translocation. In recent years,people have realized that the optimization of light environ-mental factors is one of the feasible ways to improve the yield and quality of microtubers.Microtuber which is the storage organ of plant is used as a mode organ to probe the regulation mechanism of spectral distribution on the development process of storage organ. This research is beneficial to understanding the knowledge of spectral distribution on the regulating the development process of the storage organ and will be helpful in increasing the yield and quality of microtubers.关键词
