The Effect Of Light On The Growth Of Soybean Seedlings, Mary Abrahamsen, T. W. Sudia
The Effect Of Light On The Growth Of Soybean Seedlings, Mary Abrahamsen, T. W. Sudia
Journal of the Minnesota Academy of Science
ABSTRACT- During the course of 13 days of germination and growth, the dry weights of roots, hypocotyl, and epicotyl increased in soybeans grown both in the light and in the· dark. The roots of etiolated 13-day-old soybeans were only 50 per cent of the weights of roots from similar plants grown in the light. The epicotyls of etiolated plants were only 18 per cent of the dry weight of epicotyls of light-grown plants, but the hypocoyl weights of etiolated plants were greater than those grown in the light. Cotyledon dry weight of light-grown plants was reduced by 70 per cent …
Distribution Of Foliar Applied P-32 From The Leaves Of Soybean At Various Ages, George E. Ahlgren, Theodore W. Sudia
Distribution Of Foliar Applied P-32 From The Leaves Of Soybean At Various Ages, George E. Ahlgren, Theodore W. Sudia
Journal of the Minnesota Academy of Science
Transport patterns of phosphorus-32 from the cotyledons, primary leaves and the first five trifoliate leaves of soybean were determined at various ages of these organs. The transport patterns studied indicate the same general pattern for each leaf. There is initially a bidirectional movement from the leaf that increases in its upward component as the leaf becomes older, followed by a sharp drop in the upward component and P'" transport becoming essentially unidirectional downward in the stem. At fruit development, phosphorus-32 transport becomes quite specific for fruit at the axil of a particular leaf. Contiguity to sites of high metabolic activity …
