Abstract
Bean plants grew in the greenhouse until approx. 15 days old at which time they were transferred to a dark room thermostatted at 25[degree]C. One of the primary leaves was placed in a sugar soln. and the petiole of this leaf was jacketed with a temp. control unit. In each expt. the petioles of one group of plants were subjected to a temp, program of 40[degree]C followed by 25[degree]C, and in a 2d group to 5[degree]C followed by 25[degree]C, and in a 3d group to a constant temp. of 25T. The alternating temps. were applied in a 12 hr.-12 hr. cycle for a total of 81 hrs. The maximum rate of transport of carbohydrates, as measured by stem elongation, occurred under a constant temp, program of 25[degree]C.This publication has 1 reference indexed in Scilit:
