Abstract:

The objective of this paper is to establish a set of high quality, high effective and lost-cost rapid propagation production technology about the virus-free potato plantlet. This experiment investigated that the effects of different mediums and light-temperature condition on virus-free potato rapid propagation used the ‘Zhongshu1’. The results showed that the MS and 1/2MS was the most suitable for rapid propagation because of their well and vigorous growth among five mediums. The high temperature and intense light (T3) was the best condition for rapid propagation among 4 different light-temperature conditions, and the sunny side lab room (T2) was preferable for rapid propagation because of adequate utilization of natural light-temperature. The MS/T3 appeared the best performance while there were no significant differences in the growth index among the 4 combinations. However, the 1/2MS/T2 was the preferable substitute because it can adequately utilize the natural light-temperature and reduce the cost.
