盐分和母树大小对黑松海防林种子萌发和幼苗早期生长的影响
Effects of sea water salinity and mother tree size on the seed germination and seedling early growth of Pinus thunbergii coastal protection forest
摘要
Abstract
Pinus thunbergii is the main forestation tree species of coastal protection forests in northern Shandong Peninsula of China. Its seed germination and seedling early growth were stud-ied under the conditions of different water salinity (0, 0. 02, 0. 04, and 0. 08 mol·L~(-1)) and mother tree sizes. With increasing sea water salinity, the seed germination rate, root-and plu-mule length, and the dry weights of root and plumule decreased significantly. Mother tree size had little effects on the seed germination rate, but affected the root-and plumule length and the plumule dry weight significantly. The interaction of sea water salinity and mother tree size affect-ed the root-and plumule length significantly, but less affected the germination rate and the dry weights of root and plumule.关键词
