| [effects of environmental stress on seedlings root growth and nodulation of leguminous shrubs in the dry valley of minjiang river]. | a field investigation was made to understand the seedlings root nodulation, biomass accumulation, root length, and fine root percentage of sophora davidii, indigofera lenticellata and campylotropis polyantha along an altitudinal gradient on two contrasting sloped hills (north zongqu and south jingzhoushan) in the dry valley of minjiang river. in the meantime, a greenhouse experiment was conducted to study the adaptation responses of 2 month-old s. davidii and c. polyantha seedlings root nodulati ... | 2009 | 19947198 |
| [dynamics of sophora davidii population in a hilly region closed for thirty years in loess plateau]. | taking wild grass ground as the reference, this paper studied the dynamics of sophora davidii population on the sunny, semi-sunny and semi-shady slopes of hilly region in loess plateau after 30 years closed for reforestation, and analyzed the age structure, spatial distribution pattern, life table, and survival curve of the population. the results showed that s. dvidii population in the region belonged to progressive type, with more young and less old individuals. among the three habits, semi-su ... | 2006 | 16706034 |
| [eco-anatomical characteristics of sophora davidii leaves along an elevation gradient in upper minjiang river dry valley]. | this paper studied the eco-anatomical characteristics of sorphora davidii leaves at the elevations of 1,650, 1,750, 1,850 and 1,950 m in the upper reaches of minjiang river dry valley. the indices investigated were leaf length (ll), leaf width (lw), ll/ lw, leaf area, leaf thickness, leaf epidermal thickness, leaf palisade mesophyll thickness (p), leaf spongy mesophyll thickness (s), p/s, leaf cutin membrane thickness, leaf stomatal density and area, leaf epidermis cell density and area, and lea ... | 2006 | 16689224 |
| [niche characteristics of dominant populations of sophora davidii community in loess gully region]. | based on field investigation data and employing levin and niche proportional similarity formulae, this paper calculated the niche breadth, niche proportional similarity, and niche overlap of 13 dominant species of sophora davidii community in loess gully region. the results showed that the niche breadth of the dominant populations of sophora davidii community decreased in order of sophora davidii (0.964), artemisia giraldii (0.775), arteniisia gmelinii (0.664), thenmeda triandra var. japonica (0 ... | 2005 | 16515163 |
