| 摘 要： | 对烟草花叶病损失的田间试验和统计分析结果表明:单株烟叶的产量、产值的损失率与病害级别显线性函数关系;田间的产量、产值的损失率与病株率、病情指数的关系为逻辑斯蒂模型。花叶病的发生,使受害株叶片中的蛋白质含量升高,糖含量下降,品质明显降低。

| Abstract: | Based on field experiments the tobacco yield and economic losses analyzed due to tobacco mosaic virus disease were studied by statistical methods. The results showed that the relationship between the yield loss and disease grade,and between the economic loss and the grade could be described with linear functions. The relationship between yield loss and disease incidence,between yield loss and disease index,between economic loss and disease incidence,and economic loss and disease index could be described with logistic model. The analysis of chemical composition indicates that the contents of sugar in injured leaves are reduced, but the contents of protein are increased. |
