Abstract

The effects of ultrasonic wave and polyethylene glycol（PEG） osmotic treatments on germination and the metabolic mechanism during initial germinating stages of Pinus tabulaeformis seeds were studied through an orthogonal design（L934）. The results showed that：PEG osmotic adjustment and ultrasonic treatments have different effects on the seed germination and the metabolic mechanism during initial germinating stages of Pinus tabulaeformis seeds. The effect of PEG promotes seed germination，which increases with the increment of PEG soluble concentration，and 20% PEG solution significantly promotes seed germination and significantly increases the content of soluble sugar and soluble protein during the initial germinating stages. The germination rate and germination index could be significantly increased，the decomposition of starch could be accelerated，and the content of soluble protein could be increased during initial germinating stages after the seeds treated with 59 kHz ultrasonic wave on 10 min. The best treatment combination of ultrasonic and PEG osmotic adjustment treatment was：the seeds soaked in 20% PEG solution for 24 h，and then treated with 59 kHz ultrasonic wave for 10 min. ［Ch，3 tab. 17 ref.］
