概括
切尔科斯波拉叶斑 (CLS) 的严重程度并没有显著影响甜菜的储存腐烂或呼吸. 观察到储存病原体反应的品种差异,这表明未来品种开发的潜力可以减少收获后损失.
科学领域:
- 农业科学 农业科学
- 植物病理学 植物病理学
- 收获后生物学 收获后生物学
背景情况:
- 甜菜 (Beta vulgaris) 存储时间长 (长达200天),因此容易因呼吸和腐烂而失去糖分.
- 叶斑Cercospora (CLS) 是一种可能使甜菜倾向于增加储存腐烂的疾病,影响作物产量和利能力.
研究的目的:
- 为了研究季节性Cercospora叶斑 (CLS) 严重性对甜菜中收获后储存腐烂的影响.
- 评估CLS在储存期间对甜菜根呼吸的影响.
- 为了识别存储病原体的易感性潜在的品种差异.
主要方法:
- 现场和收获后的研究是使用指定高或低CLS严重程度的甜菜进行的.
- 用Fusarium graminearum, Botrytis cinerea或Penicillium vulpinum接种了根切片,并评估了腐烂症状.
- 在存储期间,在不同的CLS级别和品种中测量了根呼吸率.
主要成果:
- 在商业品种中,在CLS水平之间没有发现存储腐烂易受性的显著差异.
- 对于腐烂的CLS影响是不一致的,并且在储存时间点和生殖质中通常不显著.
- 之前的CLS水平在储存期间没有影响甜菜根呼吸率.
- 与其他测试的病原体相比,Botrytis cinerea会引起更严重的腐烂症状.
- 观察到品种对储存病原体的反应有显著差异.
结论:
- 在经过研究的条件下,季节性CLS的严重程度似乎不是在糖中存储腐烂的重要诱导因素.
- 品种选择在甜菜的储存成功中起着至关重要的作用,病原体耐药性的显著差异.
- 了解种类对储存病原体的反应是开发改进的甜菜品种和尽量减少收获后损失的关键.

Overview of Metabolism
29.6K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

C4 Pathway and CAM
45.3K
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.
