概括
叶卷曲疾病是由白传播的病毒引起的,可以通过Capsicum annuum系列DLS-Sel-10进行管理. 这条线显示,对叶卷曲病毒 (ChiLCV) 的耐受性随着年龄的增长而增加,白不太喜欢它.
科学领域:
- 植物病理学 植物病理学
- 昆虫学 昆虫学是一门学科.
- 遗传学 遗传学 是一个
背景情况:
- 叶子病是热带地区热生产的主要威胁.
- 这种疾病主要是由白 (Bemisia tabaci) 传播的贝戈莫病毒引起的,特别是叶卷曲病毒 (ChiLCV).
- 多个贝戈莫病毒可能会导致这种疾病,使管理策略复杂化.
研究的目的:
- 描述Capsicum年菜系列DLS-Sel-10对叶卷曲病毒 (ChiLCV) 的耐药性.
- 为了比较DLS-Sel-10的抵抗水平,阶段和性质与易受感染的品种 (Phule Mukta).
- 评估DLS-Sel-10作为白载体的宿主潜力.
主要方法:
- 现场选Capsicum annuum线条以确定耐受性来源.
- 用ChiLCV对DLS-Sel-10和不同生长阶段易受感染的品种进行感染测定.
- 昆虫食试验评估白对DLS-Sel-10的偏好与敏感品种的偏好.
主要成果:

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

38.2K
The chi-square test is a statistical hypothesis test. It is used to check whether there is a significant difference between an expected value and an observed value. In the context of genetics, it enables us to either accept or reject a hypothesis, based on how much the observed values deviate from the expected values.
The chi-square test was developed by Pearson in 1990.
The first step of performing a Chi-square analysis is to establish a null hypothesis, which assumes that there is no real...
