THE RELATIONSHIP BETWEEN SEED QUALITY AND SEEDLING QUALITY OF KOREAN PINE
The seedling quality of korean pine(Pinus koraiensis Sieb. ct Zucc.) is affected by the seed quality. The results of experiments in nursery suggest that the weight of 1000 seeds should be used as a main indexfor evaluating the level of seed quality. Different size of cone would produce different seed quality. The small cones (less than 10cm in length) in which the seed quality is poor should not be used for cultivating seedlings.
