dc.description.abstractAn inbred resistance to fungal pathogens, genetic selection for ear leaf phosphorus content and the amount of mycorrhizal inoculum present in the soil at planting time were tested in regard to mycorrhizal formation in Zea mays, A significant inverse correlation between increased resistance and decreased mycorrhizal formation were observed in the five tested inbred lines. This first test verified the results demonstrated by Starke in 1979, A Spearman rank correlation was performed and was significant at the 95% level. A direct correlation was observed, during two separate tests, between high-low ear leaf phosphorus content in six inbreds and their ability to form mycorrhizal associations. As the percent of ear leaf phosphorus content increased, the percent of mycorrhizal colonization also increased. The Spearman rank correlation was significant at the 95% level. Vesicular-arbuscular mycorrhizal inoculum levels were not found to be a limiting factor in mycorrhizal formation. At ten weeks, equal levels of colonization were observed when inoculated with initial inoculum amounts at planting time.en_US
