- 园艺科学 园艺科学
- 植物生理学 植物生理学
背景情况:
- 环境波动和作物绩效的变化会对农业生产和质量标准产生重大影响,特别是对于利率较低的生产者来说.
- 这些挑战往往在作物季节结束时变得更加强烈,因为条件不太理想.
- 这项研究研究了草 (Fragaria × ananassa) 在不同季末条件下的营养质量.
研究的目的:
- 评估收获时间,道微气候和个体间植物变异对草营养质量的影响.
- 为了评估喷的黑激素在缓解季末质量下降方面的有效性.
- 了解导致水果质量在商业草生产中的变化因素.
主要方法:
- 在三周间隔的地中海生产道中进行了两次收获,该道分为几个块.
- 监测了环境因素,包括道内的光辐射.
- 评估了各个植物之间的营养含量变化.
- 分析了水分含量,抗氧化能力和与成熟相关的荷尔蒙.
- 评估了黑激素应用的影响.
主要成果:
- 季末的收获对水果水合,抗氧化能力和成熟激素产生了负面影响.

02:45Biological Clocks and Seasonal Responses
34.6K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

02:27Background and Environment Affect Phenotype
6.5K
Although the genetic makeup of an organism plays a major role in determining the phenotype, there are also several environmental factors, such as temperature, oxygen availability, presence of mutagens, that can alter an organism’s phenotype.
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
