辽东栎苗木早期生长与光的关系

In order to inquire into the relationship between the seedling growth of Quercus liaotungensis and light, using green wire entanglement shading, we set up four light condition (eg. full light, 50% of full light, 30% of full light, nonlight)to study the rate of emergence of seedlings, the height growth of nursery stock, the diameter near the earth's surface of nursery stock, the rate of net photosynthesis, transpiration and the obstruction of stoma under different light condition. The result showed that the seedling growth of Quercus liaotungensis was not suited to grow under full light, but under 50% of full light. Under 50% of full light, the rate of emergence of seedlings was the hightest . In addition , under this condition , the fastest growth of on height and the diamter near the earth's surface. At the same time the rate of net photosynthesis and transpiration was the most effective. So a conclusion was drawn that the seedling growth of Quercus liaotungensis was affected.
