| 1. | It reflects the timing of vegetative shoot extension vis-a-vis flower development .
它反映了营养小枝的伸长同花的发育在时间上的矛盾。 |
| 2. | Some cultivars also form fruit buds on the tips of the current season's vegetative shoots .
一些栽培品种也在当年的生长枝的顶端形成花芽。 |
| 3. | Wardlaw reproduced to the same scale photographs of the vegetative shoot apex of many primitive and advanced land plants .
沃德劳以同样的放大倍数复制了许多原始的和进化的陆生植物营养茎尖的照片。 |
| 4. | Morphology and cytohistological zonation appeared different between cone apex and the vegetative shoot apex
雌球果原基与营养茎端在外部形态及内部细胞组织学分区结构有明显差异。 |
| 5. | The average photosynthesis rate of vegetative shoots at all radiation gradients was 1 . 35 times sizes of reproductive shoots . the transpiration rates of shoots were increasing with the intensity of simulated photosynthetic radiation
两种类型植株蒸腾速率日变化趋势基本一致，在9 10时达到最大值，随着气温和叶温的升高，气孔导度的降低，水分供应的减少，蒸腾速率逐渐减小。 |
| 6. | With intensifying of simulated photosynthetic radiation , the photosynthesis rates for all the shoots were increasing before radiation intensity reached 1200 - 1400 mol - m - 2 - s1 and 1000 - 1200 mol - m - 2s - 1 respectively for vegetative shoots and reproductive shoots
由此可见，大气污染、烟雾和气溶胶导致的有效光辐射的减小对贝加尔针茅的光合积累影响较小，而水分利用效率则能有所提高。 |
| 7. | In order to explore the influence of ecological factors on plant physiological characteristics , we carried out a series of experiments on stipa baicalensis community . with the increasing of co2 concentrations , the transpiration rate of stipa baicalensis , either for vegetative shoots or for reproductive shoots were significantly increasing . the average transpiration rates of vegetative shoots were 1 . 77 times sizes of reproductive shoots
生殖枝与营养枝光合速率均随模拟光辐射强度的增强而增大，营养校与生殖校分别在光辐射强度为1200 1400umol ? m士s ‘及1000 1200umol ? m毛s1时达到光合速率的最大值，营养枝光合速率均值为生殖枝的1 |
| 8. | The average photosynthesis rate of vegetative shoots was 1 . 72 times sizes of reproductive shoots . despite of differences in the physiological functions , the water use efficiency of vegetative and reproductive shoots had a linear increasing with the co2 enrichment . so we draw a conclusion that co2 enrichment can obviouely promote the water use efficiency of c3 plants
29倍；模拟光辐射强度从0增至800umol ? m zs ”过程中，两种类型植株水分利用效率均呈骤增趋势，模拟光辐射强度超过800nmol ? m ”毛’ ‘后，水分利用效率增幅不大，甚至有所下降。 |
