The seed of Pinus elliottii seeds under the natural conditions is necessary for the next year or even three years to achieve germination. In this paper, the seeds of the seeds without acupuncture are used to study the permeability (permeability and permeability) Time agglutination treatment, different concentrations of GA3 solution and chromatography treatment and other aspects of the experiment to find the factors that impede the seed germination, to understand the seeds of the seeds without acupuncture, and to understand the germination and physiology of seeds without acupuncture. The results showed that the low temperature and stratification treatment of the seeds without the first warm temperature was more favorable to the physiological maturation and germination of the seeds.
