Photosynthesis, Carbohydrate Metabolism, and Export in Beta vulgaris L. and Phaseolus vulgaris L. during Square and Sinusoidal Light Regimes.
Rates of photosynthesis, sucrose synthesis, starch accumulation and degradation were measured in sugar beet (Beta vulgaris L.) and bean (Phaseolus vulgaris L.) plants under a square-wave light regime and under a sinusoidal regime that simulated the natural daylight period. Photosynthesis rate increased in a measured manner in direct proportion to the increasing light level. In contrast to this ...
متن کاملEffect of Rapid Changes in Sink-Source Ratio on Export and Distribution of Products of Photosynthesis in Leaves of Beta vulgaris L. and Phaseolus vulgaris L.
Effects of increasing sink-source ratio on rate of translocation and net carbon exchange were studied by darkening all but one source leaf of Beta vulgaris L. or one primary leaf of Phaseolus vulgaris L. Rates of export of labeled material and patterns of its distribution among sinks were studied by means of GM detectors. Changes in export and import rates were compared with adjustments in star...
متن کاملZinc Nutrition and Starch Metabolism in Phaseolus vulgaris L.
The effect of Zn nutrition on leaf starch metabolism was studied in two navy bean (Phaseolus vulgaris L.) varieties, Sanilac and Saginaw. Sanilac is much more susceptible to Zn deficiency than is Saginaw. The variables examined in these two strains were starch content, the activity of soluble starch synthetase (ADP-glucose: starch alpha-4-glucosyltransferase, EC 2.4.1.b), and the size and numbe...
متن کاملDiurnal Pattern of Translocation and Carbohydrate Metabolism in Source Leaves of Beta vulgaris L.
Transitions in carbohydrate metabolism and translocation rate were studied for evidence of control of export by the sugar beet (Beta vulgaris L. Klein E.) source leaf. Steady-state labeling was carried out for two consecutive 14-hour light periods and various quantities related to translocation were measured throughout two 24-hour periods. Starch accumulation following illumination was delayed....
متن کاملWATER ABSORPTION IN BEAN SEEDS (Phaseolus vulgaris L.) DURING PROCESSING
The purpose of this paper was to estimate and to evaluate the hydration curves of three kinds of dry bean varieties (Phaseolus vulgaris L.), besides adjusting the Peleg’s model to the experimental values under several soaking temperatures. Bean seeds of pinto, black and red kidney varieties were soaked in distilled water in the temperatures of 20, 30, 40 and 50 °C. The constant C1 (Peleg rate c...
