| 1. | The chromosome karyotype analysis on agropyron crestatum 冰草染色体组型分析 |
| 2. | Physiological and biochemical changes in rosana western wheatgrass seed during seed deterioration 蓝茎冰草种子劣变过程中生理生化变化 |
| 3. | ( 3 ) wheatgrass could reduce water dissipation by shutting up stoma and let some leaves wither 3 、冰草植株在干旱条件下关闭气孔,以减少水分散失,叶片萎蔫,以减少蒸腾面积。 |
| 4. | Grass varieties grown include timothy hay , smooth brome grass , meadow brome grass , wheat grasses , tall fescue , orchard grass and wild rye 栽培的牧草品种包括梯牧草无芒雀麦草草地雀麦草冰草高羊茅野茅和野麦。 |
| 5. | ( 3 ) wheatgrass could control na + transport to upground by withholding na + in root which can keep the balance of ion of upground 3 、冰草植株通过将na ~ +截留在根部,控制na ~ +向地上部分的运输,以维持植株代谢旺盛部位的离子平衡。 |
| 6. | ( 2 ) wheatgrass could restrain the growth of upground of plants more than that of underground , so the plant could absorb more water and reduced transpiration 2 、冰草植株对地上部分生长的抑制大于对地下部分生长的抑制,这样可以增强根系吸水,较少叶片的蒸腾失水。 |
| 7. | Not only is it an important forage grass , but also has an important ecological and genetic value because of its drought - resistant , cold - resistant and barren - tolerant traits 冰草不仅是一种重要的牧草,而且由于它的抗旱、抗寒和耐荒漠的特性,又是一种具有重要生态和遗传价值的植物材料。 |
| 8. | The highest biomass of aneurolepidium dasystachys appeared in august , while that of stipa bungeana appeared in may . the sequence of the highest biomass per area was : aneurolepidium dasystachys } achnatherum splendens } stipa bung 7 、对照牧草厚穗冰草于8月份生物量达到高峰,本氏针茅则于5月份达到高峰期。 |
| 9. | The reasons of strong salt resistance had three aspects : ( 1 ) wheatgrass could reduce the potentiality penetration in cell by increasing the osmoregulatotory substance , so the plants could absorb more water by roots 得出冰草植株耐盐有三个原因: 1 、冰草植株能够增加可溶性渗透调节物质,以降低细胞渗透势,保持植株根系吸水。 |
| 10. | Prairie grassland accounts for thirty percent of the total area . level and boundless , aneurolepidium , needlegrass and wheatgrass mainly grow there . it has a high quality herbage , making it good pastureland 又称高平原草原,约占呼伦贝尔草原总面积的30 % ,地势平坦,一望无垠。主要草种有硷草、针茅、冰草,牧草质量高,是牛羊最理想的放牧地。 |
