摘  要：
以2个在山东广泛种植的品种为材料,研究了银杏种子发芽特性及其与含水量、贮藏方式的关系。结果表明:新鲜龙眼种子的发芽势、发芽率分别为81.7%、85.1%,新鲜梅核种子的发芽势、发芽率均为90.5%;但随着种子干燥脱水,种仁硬化,种子发芽力和活力迅速降低,种子含水量降低到30%以下,发芽力基本丧失。与新收获的种子相比,沙藏半年后种子的发芽力、活力略有提高,种子含水量也有所提高;而在冰箱塑料袋中贮藏半年后,虽种子含水量降低不明显,但发芽力、活力均显著降低。2种贮藏方式都未降低种子无胚率。

摘  要：
With two common varieties of Shandong province as the test materials, the relationship among germination characteristic and moisture content and storage methods was studied in Ginkgo Seeds. The results showed that the germination energy of seeds in Longyan and Meiheafter were 81.7 % and 90.5% respectively, the germination percentage of seeds after harvested in Longyan and Mei- heafter were 85.1% and 90.5% respectively; the germination energy and germination percentage of seeds reduced rapidly with dehydra- tion of seeds, and the seed moisture content was less than 30%, basically its germination ability lost. By comparison with newly harvested seeds, the germination ability,vigor and moisture content of seeds increased slightly after half- year sand storage; the germination ability and vigor of seeds decreased significantly after half- year freezer storage, but the decrease of its moisture content was not obvious. The rate of embryoless seeds after stored had no change with seeds before stored.
