Conteúdo: 	Stunted and chlorrotic citrus seedlings growing in fumigated nurseriesin California and Florida werenonmycorrizal, and Endogone spores were not found associated with their roots; whereas seedlings growing normally in scattered areas or these nurseries were mycorrizal, and Endogone spores were present. Stunted plants from nurseries grew normally after inoculation with Endogone mosseae, an endomycorrizal fungus. Noninoculated citrus seedlings grew poorly in steamed, autoclaved, or methyl-bromide-treated soil in greenhouse experiments. Plants inoculated with E.mosseae produced  excellent growth in these treated soil. Inoculation also improved the growth of citrus seedlings in an Illinois field plot that had been fumigated with methyl bromide. All mycorrizal planthad a greater dry weight and a higher percentage of phosphorus than did nonmycorrhizal plants. Stunting and chlorosis of citrus in fumigated or heat-treated soils have previously attributed to soil toxicity. Our evidence indicates that the major cause of this problem is inadequate nutrition brough about by the killing of mycorrhizal fungi.
