Effects of Meloidogyne incognita on Nitrogen Fixation in Soybean.
The effects of a North Carolina population of Meloidogyne incognita on N fixation on root-knot-susceptible 'Lee 68' and moderately resistant 'Forrest' soybean were evaluated 50, 75, I00, and 135 days after inoculation with nematodes. Nematodes stimulated N fixation in Lee 68 by 50 days and in Forrest by 75 days. At all other intervals, N fixation was either depressed or unaffected by nematodes....
متن کاملSpatial and Temporal Interactions of Meloidogyne incognita and Soybean.
The spatial and temporal dynamics of Meloidogyne incognita, relative to soybean shoot and root growth in field microplots, were determined at 11 sampling dates during a growing season. The population dynamics of M. incognita on soybean were dependent on initial population (Pi), soil moisture, and root spatial distribution. Final egg and juvenile population densities were greatest in plots with ...
متن کاملThe Influence of Temperature on Meloidogyne incognita on Soybean.
The effects of temperature and initial inoculum density of Meloidogyne incognita on soybean growth and nematode reproduction were investigated in greenhouse temperature tanks and in controlled-growth chambers. The interactions of initial inoculum density (P(i)) and soil temperature in effects on shoot growth were adequately described by multiple-regression models. At the highest temperatures (3...
متن کاملRelative Virulence of Meloidogyne incognita Host Races on Soybean.
Sensitivity and host efficiency of susceptible ('Lee 68', 'Coker 156') and resistant ('Bragg', 'Centennial', 'Forrest', 'Lee 74') soybean (Glycine max (L.) Merr.) cultivars for races of Meloidogyne incognita (Mi) were determined in greenhouse experiments. Eight Mi populations collected from the southeastern United States were utilized. All Mi races reproduced readily on Lee 68 and Lee 74 and mo...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
