Abstract:1.The best terms for storage of the Pinus tabulaeformis seed accelerated germination by sack conditioned air with silica gel transom are as follows:a.The normal atmospheric temperature (18—20℃);b.The rate of water absorbtion about 13%;c.The oxygen content 5—7% in room air and carbon dioxide content 6—8%.Under the conditions mentioned above,the split Pinus tabulaeformis seed by accelerating germination is stored after 15 days,its germination percentage also had more than 85 percent. 2.The accelerated germination seed emerged earlied 5—20 days in comparison with the not accelerated germination seed sown in control area in broadcast seedling afforestation test.It‘s rate of germination raised 21.4 to 49.7 percent,the date of emergence shortened 13 to 20 days,and also the emergence demended rainfall less.Owing to the long growing time the xylary tissues of the seedling increased the same year. Its survival rate over wintering and afforestation raised 16.03 and 14.13 percent in average respectively.
