科学领域:

环境科学环境科学
农业学是一种农业学.
植物生理学植物生理学

背景情况:

(Pb) 污染对环境和健康构成重大风险,需要有效的土壤整治策略.
生物炭 (BC) 显示了减轻Pb毒性的潜力,而三糖 (Tre) 提高了植物的应激耐受性,但其在Pb毒性减轻中的作用尚未被探索.

研究的目的:

调查BC和Tre在减轻大米植物Pb毒性的联合作用.
评估BC和Tre联合应用对大米产量,生理参数和Pb积累的影响.

主要方法:

大米植物接受了控制,Pb压力,Pb + BC,Pb + Tre和Pb + BC + Tre处理.
测量了关键的生理指标,包括叶绿素,相对含水量 (RWC),甲 (MDA) 和过氧化 (H2O2).
分析了土壤和植物组织中的Pb度,以及土壤营养素的可用性.

主要成果:

压力显著降低了大米产量,叶绿素和RWC,同时增加了植物和土壤中的MDA,H2O2和积累.
无论BC和Tre都单独减轻了Pb的毒性,但它们的联合应用产生了更好的结果.
同时应用BC和Tre增强了光合作用颜料,含水量,蛋白和蛋白质合成以及抗氧化活性,同时减少了Pb的吸收和转移.

结论:

同时应用BC和Tre是修复受Pb污染的土壤的实用和有效策略.
这种综合方法通过减少Pb的毒性,可用性和吸收,显著提高了大米的生产力.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Plant Breeding and Biotechnology

Plant Breeding and Biotechnology

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

Responses to Salt Stress

Responses to Salt Stress

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.
