科学家们表示：“实际上，以往的研究低估了临界温度。

The threshold temperature has been substantially underestimated in previous studies.

因此，选育不育临界温度低、育性相对稳定的实用光温敏核不育系，探讨不育系育性转换规律、育性遗传规律及生理生化特性，在理论和实践上都具有重要意义。

So it is very important for the theory and practice to research and insight the fertility alteration, fertility inheritance and physiological and biochemical characters of PTGMS lines.
