背景情况:
- 土壤 (Cd) 污染对食品和料生产构成风险.
- 众所周知,向日 (Helianthus annuus) 强烈地积累.
- 人类食品种子中Cd的监管限制对公共健康至关重要.
研究的目的:
- 要量化三种在Cd丰富土壤中种植的日种子品种中的 (Cd) 含量.
- 调查种子洗对向日种子内Cd分布的影响.
- 探索日中Cd积累和转移的遗传变异性.
主要方法:
- 三种向日品种 (ES Biba,Extrasol,Vellox) 在石灰质土壤中田间种植,每日1毫克Cd/kg.
- 在整个种子和种子部分 (核和树皮) 中总Cd含量的定量.
- 分析不同品种的内核和船体之间的Cd分布.
主要成果:
- 这三种向日品种中的Cd含量都超过了监管限制的0.5毫克Cd/kg.
- 种子清洗并没有改变总Cd含量,但在船体的费用上稍微增加了内核Cd.

C4 Pathway and CAM
45.5K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Adaptations that Reduce Water Loss
25.6K
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.
