研究的目的:
- 评估不同根茎 (西红,茄子,夜) 对Cyphomandra betacea (tamarillo) 幼苗的生长和积累的影响.
- 确定最有效的根茎来增强Se污染土壤中种植的tamarillo中的吸收.
主要方法:
- 在Solanum lycopersicum (西红),Solanum melongena (茄子) 和Solanum nigrum (夜色) 的根茎上移植Cyphomandra betacea的切片.
- 移植和非移植幼苗之间的生长参数,光合作用活性,酶活性和Se含量的比较.
- 分析了根茎生物质,酶活动和子 Se 含量之间的相关性.
主要成果:
- 所有根茎都增加了后代生物量,番茄的增加率最高 (146.1%).
- 夜影根茎显著增加了后裔中的Se含量,而番茄和茄子没有.

Responses to Salt Stress
13.1K
Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

Adaptations that Reduce Water Loss
25.5K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
