| 2. | Study on the community ecological characteristics of defoliated broadleaved forests of shiren mountain natural reserve 河南省石人山自然保护区落叶阔叶林群落生态特征 |
| 3. | Study on characteristics of faded and defoliated foliage in soil and water conservation ecological rehabilitation region in zichuan 淄川水土保持生态修复区枯落物持水特征研究 |
| 4. | The light saturation point was lower of defoliated plants than that of non - defoliated plants . with reduced light irradiance , light saturation point also decreased 叶损失植株的光饱和点要低于未受损植株,随光照强度的降低,植株的光饱和点逐渐下降。 |

| 7. | Look at the jungles in brazil , the environmental abuse there , the destruction of the forests there , the rain forests . the land is being defoliated and that results in floods . and these are not unrelated to the problem of overpopulation 在巴西丛林里,也有环境破坏的问题,他们破坏那里的雨林区,在土地上施放落叶剂造成水灾,这和人口过多的问题也有关系。 |
| 8. | Both reduced irradiance and defoliation caused decreased slm ( specific leaf mass ) . ( 4 ) generally , chlorophyll content and chlorophyll concentration increased with reduced light levels , the ratio of chlorophyll a to chlorophyll b of defoliated plants was higher than those of controlled plants , while in latter period , the results were contrary to that of the former period ( 4 )叶绿素含量和浓度总体上都随光照水平的降低而升高,叶绿素a / b在高光条件下显著大于低光水平下的植株,叶损失植株的叶绿素a / b值处理初期小于未受损植株,处理后期则大于未受损植株。 |
| 9. | The quantity of increased leaf efficiency contributed to the aboveground biomass gain after defoliated are different at different irradiance . at the initial stage , the increased leaf efficiency of defoliated plants contributed more to biomass increment of aboveground under higher light level than those under lower irradiance . as the treatment time extended , the contribution to growth of increased leaf efficiency of plants under intermediate light level went beyond those under full irradiancy ( 2 )叶受损的植株叶效率显著高于未受损植株;光照强度越高,植株的叶效率越高;受损植株增加的叶效率在不同光照条件下对生长的贡献大小不同,处理初期,全光照下叶损失植株增加叶效率对地上部分的生物量增加贡献大于中度光照,大于低光照下植株,随处理时间的延长,中度光照下的植株增加叶效率对生长的贡献逐渐超过了全光照下植株。 |
| 10. | The process of initial culture showed quite difference in various hostas . h . ventricosa and h . " so sweet " were easier , while h . " frances williams " and h . " gold standard " were difficult . using shoot tip ( peak bud ) as explant was proved the effective method for improving survival ratio when hostas would defoliate or have defoliated in autumn or winter rather than in summer 玉簪属不同种类的组培初代建立存在着一定的差异,如h . ventricosa和h . ‘ sosweet ’较容易建立,而h . ‘ franceswilliams ’和h . ‘ goldstandard ’比较困难;应在冬季玉簪属植物将要落叶或已落叶后取茎尖(顶芽)进行初代建立,最好避开夏季,来提高初代建立的成活率。 |
