The response of legume seedlings to light intensity, temperature and soil moisture

, : The response of legume seedlings to light intensity, temperature and soil moisture. Diss. Abstr, 16: 12, 2270

This study of the response by seedlings of lucerne, red clover and birdsfoot trefoil was carried out during 1955-6 using (a) controlled climate chambers with 200-1200 ft. candles of light, temperatures of 60-90 degrees F. and 4 soil-moisture levels, and (b) a greenhouse and an air-conditioned laboratory in which treatments included 4 growth periods of" varying length before exposure to various light quantities, 5 quantities of light per day and growth periods of 15 and 30 days under the light treatments. The responses of the tops and roots to the 200-1200 f.c. were curvilinear and linear, respectively. At 600 f.c. and 60 degrees F., top growth of the 3 species was much greater, root growth of lucerne less than twice and of red clover 4 times greater than that attained at 1200 f.c. and 90 degrees F. The response of tops and roots of the 3 species to 5 quantities of light per day was linear when the light treatments were of varied duration at intensities of 1200 and 200 f.c.
