The Principles and Effect of Handling Seeds of Pinus massoniana by IDS Method

Researches were conducted on the sucking and losing water rate of different quantity of Pinus massoniana Lamb and how long time it needed to keep balance during moister incubation under the same condition. Pinus massoniana Lamb seeds which had GP 74% and GE 57% were disposed by use of IDS technique.The GP of the other seeds in the house increased to 92% and the GE to 81% after removal of filled dead seeds from the sample.the results of vigor testing showed that IDS technique did not bring the bad influence upon the vigor of Pinus massoniana Lamb seed,and on the contrary markedly increased the vigor index.
