- 阐明谷物填充过程中的温度与特定质量参数之间的关系.
- 为优化种植实践和育种耐热品种提供见解.
主要方法:
- 实地实验是在三个生长季节 (2020-2022) 的两个地点进行的.
- 分析了小麦的质量参数,包括谷物蛋白质含量,湿质,SDS沉量和Zeleny沉量.
- 测量了谷物产量,并与播种日期和环境温度建立了相关性.
主要成果:
- 延迟播种日期导致谷物蛋白质含量增加和湿质,但SDS和Zeleny沉积量减少,表明质强度降低.
- 谷物填充期间的较高温度,与播种延迟相关,对质质量产生了负面影响.
- 在所有实验条件下,观察到环境温度和谷物产量之间存在负相关性.
结论:
- 早期播种日期有利于更高的谷物产量和更优质的谷物质量,这是由于在较冷的条件下延长谷物填充.
- 延迟播种日期导致尽管蛋白质含量增加,但质强度受损.
- 优化播种日期和开发耐热的小麦品种是减轻气候变化对小麦生产影响的重要策略.

02:16Light Acquisition
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...
