| 摘 要： | 进行了黑龙江西部半干旱地区17种乡土园林地被植物的25℃恒温和15℃12h与25℃12h变温2个处理的种子发芽试验，计算了发芽率、发芽势、发芽指数、日均发芽率。结果表明，12种地被植物在25℃恒温和15／25℃的条件下种子发芽率高于70％，可选择种子繁殖；15／25℃交替变温对地被植物种子发芽有促进作用。 |

| Abstract: | Experiments of seed germination of constant temperature of 25 ℃ and 2 treatments of variable temperatures of 15 ℃ 12 h and 25 ℃ 12 h were conducted in the west semi-arid area of Heilongjiang Province.The germination rate,germination energy,germination index,daily mean germination rate were calculated.The result shows that the germination rate of 12 species of ground cover plants under 15/25℃ and constant temperature of 25 ℃ are higher than 70%.Seed propagation should be selected under upper temperature.Variable temperatures of 15/25℃ have promotion on seed germination of ground cover plants. |
