五.应用问题人们一定要问,组织培养有什么用呢?即是说,应用组织培养可以研究那些问题呢?这一节就预备在这方面作一些说明。首先,还想先说明一个问题,即利用组织培养作实验有那些优点,同时还有什麽缺点。用植物来做实验,所遇到的第一个问题,就是个体间的差異问题,亦即个体间遗传性的差異。所以常常要培养纯系品种,而培养纯系品种不僅需要很长久的时间,而且也是很困难的。如果所用品种个体间的差異太大,就很难得到预期的结果。利用组织培养做材料,就可以解决这个问题。前面已经提到过,如何建立组织培养的无性繁殖系,並说明了
V. Application issues People must ask, what is the use of organizational training? That is, the application of organizational training can study those problems? This section is prepared to make some explanations in this regard. First of all, also want to explain a problem, that is, the use of tissue culture for experiments have those advantages, but also what are the shortcomings. The first problem we encountered when experimenting with plants was the problem of differences among individuals, that is, the genetic differences among individuals. Therefore, it is often necessary to cultivate pure lines, while cultivating pure lines not only takes a long time, but also is very difficult. If the difference between individuals used in the species is too large, it is difficult to get the desired result. The use of tissue culture materials, we can solve this problem. As mentioned earlier, how to establish a clonal line of tissue culture has been explained
