Effects of soil moisture, temperature and nutrient availability on the population dynamics of Mucor piriformis.

ABSTRACT :

 

The effects of soil moisture, temp. and nutrient availability on the population dynamics of M. piriformis were studied using moisture levels from -0.1 to -40 kPa, temp. from -1 to 25 deg C, and 3 nutrient levels adjusted with pear juice. All 3 factors affected the population dynamics of M. piriformis in soil. Few interactions were observed consistently. Populations of M. piriformis were higher in soil at -0.1 kPa than in drier soils. Propagule density was highest in soil at 5 and 10 deg during the first 30 d of the study but was greater at -1 and 5 deg during the last 30 d. Propagule density consistently increased as soil nutrient concn increased. Results are discussed in relation to dynamics of M. piriformis in pear orchard soils.
