| 英文摘要 | We used populus yunnanensis dode., a native dioecious species in southwestern china, as a model species to study morphological, physiological, biochemical and ultrastructural responses to drought, salinity and their combination. females exhibited more growth inhibition, gas exchange rate depression and reactive oxygen species (ros) accumulation; higher lipid peroxide levels, lower osmotic adjustment capacity and ascorbate-glutathione cycle enzyme activities; and more damage to cell organelles than did males under drought, salinity and especially under their combination. in addition, we found sex-specific responses in total chlorophyll content (tc), carotenoid concentration and carbon isotope composition under different osmotic stresses. our results indicated that: (1) females are more sensitive and suffer from greater negative effects than do males under drought, salinity and especially under their combination; (2) sexual differences in adaptive responses to drought, salinity and their combination are context dependent; and (3) sex-specific reactions under a combination of stresses are distinct from single-stress responses. thus, these results provide evidence for adaptive differentiation between sexes in responses to osmotic stresses and in the sensitivity to environmental change. |
