摘要
通过对感染苜蓿霜霉病植株的株高、鲜重、分枝数、生殖枝数和花序数的测定,研究了苜蓿霜霉病对苜蓿生长的影响.结果表明:感染苜蓿霜霉病的苜蓿植株与健康植株相比,其株高、鲜重、分枝数、生殖枝数和花序数分别下降了10.40％～36.50％、18.61％～64.55％、4.92％～36.87％、17.90％～86.15％和17.75％～87.50％,叶片含水量和叶绿素含量分别下降了7.48％～43.02％和28.42％～68.63％.
Abstract
By measuring the plant height,fresh weight,number of branches,number of reproductive branches and inflorescences of plants infected with alfalfa downy mildew,the effects of alfalfa downy mildew on alfalfa growth were studied.The results showed that the plant height,fresh weight,number of branches,reproductive branches and inflorescences of alfalfa plants infected with alfalfa downy mildew decreased by 10.40％～36.50％,18.61％～64.55％,4.92％～36.87％,17.90％～86.15％and 17.75％～87.50％,respectively.The water content and chlorophyll content of the leaves decreased by 7.48％～43.02％and 28.42％～68.63％,respectively.
