烟草气候斑点病研究与综述

Tobacco Weather Fleck Disease

烟草气候斑点病是以臭氧为主的大气污染所致的一种非浸染性叶斑病害，对烟叶的产量和质量都有很大影响，20世纪80年代以来逐渐成为我国烟叶生产的主要病害之一。

Tobacco weather fleck is a kind of un-infectious diseases of tobacco leaf , which decrease the quality and the yield of tobacco leaf .

选择抗性不同的6个烤烟基因型，采用P（×P-1）/2双列杂交遗传交配设计方法，分析了烟草对气候斑点病的抗性（病情指数）和气孔导度的遗传方式。

Six tobacco ( Nicotiana tabacum ) genotypes were selected as the parents of P ×( P-1 ) / 2 incomplete diallel cross to determine combing ability and genetic model of stomatal conductance on tobacco leaves and disease resistances to weather-fleck .
