| 摘 要： | 以1年生红皮花桑为材料,采用盆栽的方法,研究了不同水分条件下条墩桑幼苗的生物量、荧光参数、净光合速率、气孔导度、蒸腾速率及水分利用效率的变化.结果表明:随着干旱胁迫程度的增加,植株地上部分的生物量和总生物量逐渐降低,但光合产物向根部的分配比例逐渐增大,根冠比逐渐增加;叶片的荧光参数Fo、Fv和Fv/Fm逐渐降低;气孔导度、蒸腾速率、净光合速率和水分利用效率逐渐下降.

| Abstract: | One-year-old Morus alba seedlings were cultivated in pots containing soil with different water contents to study the biomass,chlorophyll fluorescence parameters,net photosynthesis rate,stomatal conductance,transpiration rate and water use efficiency of the seedlings in response to diverse water stress.The results showed that the aboveground biomass and total biomass decreased with increasing water stress.However,more photosynthetic products were transferred to the roots in relation to the aboveground parts ... |
