Abstract
Studies were conducted to determine the effect of externally applied growth hormones on winter rye (Secale cereale var. cougar). The rye was grown under the snow in a specially prepared tunnel on a mountain side near Logan, Utah. These plants showed a remarkable ability to grow at 0°C. Three growth hormones, kinetin, gibberellic acid (GA), and auxin (indole-3-acetic acid) were externally applied to rye seedlings growing in the tunnel. These seedlings were alter weighed, measured and tested for soluble protein content. The three hormone treatments had no significant effects on the fresh weights or shoot lengths of the rye. GA however, had a significant effect on the soluble protein content of the young shoots. Shoots treated with GA showed a marked decrease in soluble protein content. Kinetin and IAA had no significant effect on the soluble protein content of the rye.
