Abstract
Although it has been suggested that the maximum axial growth pressure of roots is temperature-dependent, this has not previously been tested experimentally. In this paper we report the temperature-dependence of the maximum axial growth pressure of completely mechanically-impeded roots of pea (Pisum sativum L. cv Meteor). Maximum growth pressures were somewhat lower at 15 and 20°C than at 10, 25 or 30°C, but there was no overall trend for maximum growth pressure to increase or decrease with temperature. Turgor pressure in unimpeded roots varied little with temperature and we suggest that cell wall tension in completely impeded roots also varies little with temperature.
