    Description

    Water relations and root growth of shortleaf pine (Pinus echinata Mill.) were studied four weeks after seedlings from a half-sib family had been transplanted to one of three regimes of soil water availability at a root zone temperature of either 15 or 20 °C. About one-third of the variation in new root growth was explained by the root zone environment. The interaction between root zone temperature and soil water availability accounted for 10% of the variation in new root growth. In the most favorable root environment, new roots averaged 620 mm2 of projected surface area. Leaf water potential increased exponentially with new root projected surface area, becoming constant at about 300 mm2. Leaf conductance and root system water flux increased linearly with new root growth.
