| 1. | Plants generally absorb and translocate relatively small amounts of arsenic into aboveground parts .
植物常常将少量的砷吸收和转移到地上部分。 |
| 2. | The growth of the aerial portion was closely related to the supply of available calcium in the soil .
地上部分的生长、与土壤有效钙的供应密切相关。 |
| 3. | Studies on chemical components of cirsium segestum
竹叶防风地上部分的化学成分研究 |
| 4. | There were higher chi content and lower chi a / b ratio in leaves of seedling growing under k . candel forest than those growing at bare tidal flat
低盐下桐花树幼苗中五种离子都趋于分配到地上部分，以提供枝叶生长 |
| 5. | The ratio of biomass in different layer was almost the same in different periods and the majority of biomass distributed in ocm to 100cm above ground
地上部分生物量主要集中在0 - 100cm ，各时期产量结构趋势几乎相同。 |
| 6. | The gmdreba , gmdrebb and gmdrebc genes were expressed at different level in aerial parts of soybean , but undetectable in root
基因gmdreba ， gmdrebb和gmdrebc在大豆地上部分分别呈不同水平表达，而在根中检测不到它们的表达。 |
| 7. | ( 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。 |
| 8. | The result show that defoliation ca n ' t reduce but increase leaf efficiency , and moderate shade will improve plants " aboveground growth
本实验结果表明适度叶损失不但不会降低，相反会增加植株的叶效率，适度遮荫会改善叶损失植株地上部分的生长。 |
| 9. | Sonneratia ) that protrudes well above soil level the aerial part is covered with lenticels through which gases can diffuse to and from the highly developed system of intercellular airspaces
地上部分被有皮孔，气体可以通过皮孔从细胞间隙的高度发达系统间进出。 |
| 10. | ( 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。 |
