Photoassimilates are likely to be limiting for root growth under the following conditions:
Olow light intensities, moderate nitrogen fertilization rates, and optimum temperatures for shoot growth.
Ohigh light intensities, high nitrogen fertilization rates, and high temperatures for shoot growth.
Olow light intensities, high nitrogen fertilization rates, and optimum temperatures for shoot growth.
Ohigh light intensities, moderate nitrogen fertilization rates, and high temperatures for shoot growth.
