ROOT TEMPERATURE EFFECT ON APPARENT RESISTANCE TO WATER IN THREE CUCURBIT SP.
Higher root temperature resulted in an increase in plant growth, transpiration and exudation rates; leaf water potentials and stomata conductance were also raised at the higher soil temperatures.
Calculated apparent root resistance for the whole plants and the detopped root systems indicated a reduction in resistance with elevation of temperature. This effect was strongest in the lower temperatures.
It was also found that melons were most sensitive to low root temperature.
