Effect of Low Soil Temperature and Soil Disturbance on Early Root Growth and Mycorrhizal Association in Cotton

J. C. Zak and B. L. McMichael


 
ABSTRACT

The growth and survival of cotton seedlings on the Southern High Plains have been shown to benefit from their association with arbuscular mycorrhizal (AM) fungi. Seedlings that quickly developed mycorrhizal were better able to survive wet soil conditions than plants with low levels of AM colonization. The study presented here is part of an ongoing effort to understand how management practices in cotton production systems and abiotic conditions on the Southern High Plains interact to impact the survival and production of AM inoculum from year to year. Specifically we examined the effects of soil disturbance, soil temperatures, and soil moisture on AM colonization of cotton.
