Hydric and saline stress on Phaseolus lunatus L. seeds

Functional properties of proteins from Lima bean (Phaseolus lunatus L.) seeds.

Functional properties were identified for the total globulin (TG), 7S and 11S fractions of Lima bean (Phaseolus lunatus L.) seeds. The 11S component accounted for 58.3% of TGs and the 7S for 41.7%. Solubility was higher in the 7S fraction, especially at alkaline pHs. Water-holding capacity was similar (3 g water/g sample) in both globulin fractions. Oil-holding capacity was higher in the 11S fr...

Ecogeography, demography, diversity and conservation of Phaseolus lunatus L. in the Central Valley of Costa Rica

Abscisic Acid Accumulation in Developing Seeds of Phaseolus vulgaris L.

Free and bound abscisic acid (ABA) in the pod, seed coat, and embryo were determined separately throughout seed development of Phaseolus vulgaris L. cv. ;Taylor's Horticultural.' An internal standard method of gas-liquid chromatography was used for ABA quantification. In the embryo, two peaks of free ABA occurred at days 22 (1.18 micrograms per gram or 5.5 micromolar) and 28 (1.74 micrograms pe...

WATER 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...

Evidence for two gene pools of the Lima bean, Phaseolus lunatus L., in the Americas

The lima bean, Phaseolus lunatus L., is a bean species with a broad distribution in the Americas that rivals that of common bean (P. vulgaris). In order to better understand the organization of genetic diversity and the pattern of domestication in lima bean, a review was conducted of the available information on the geographic distribution of wild and cultivated forms of this species. In additi...
