Effect of Root/Leaf Temperature Differentials on Root/Shoot Ratios in Some Pasture Grasses and Clover

Twelve pasture species were grown in the same aerial environment, but with five constant soil temperatures ranging from 5 to 35 °C, to determine the influence of root temperature on the weight of roots per unit weight of foliage (R/S ratio). This ratio varied by a factor of 2 to 8 within species. Us... View More
