英文摘要 | Photosynthesis and growth characteristics of Parthenocissus quinquefolia were measured under differing soil water availability within a pot. Decreased soil moisture significantly reduced the leaf relative water content (RWC) and the above- and below-ground biomass. However, more biomass was allocated to the root than to the leaf Net photosynthetic rate (P-N), stomatal conductance (g(s)), and transpiration rate (E) were also significantly decreased but water use efficiency (WUE) was increased. Midday depressions in P-N and g, were not evident for the well-irrigated plants. With the lower water availability, midday reductions in P-N and g, were much more marked and the duration of the depression was longer. Additionally, the P-N-irradiance response curves also indicated that water supply affected photosynthesis capacity. The growth and photosynthetic response of P. quinquefolia to water supply indicated that this species could resilient to water availabilities and adapt to Hunshandak conditions very well. |
