Dissemination pathways of common bean (Phaseolus vulgaris) cultivars from their areas of domestication to other parts of the Americas were determined using phaseolin type, as determined by 1-dimensional SDS/PAGE. Common bean cultivars of lowland South America exhibited approximately equal numbers of'S' and "T' phaseolin types. "S" cultivars of that region may have been introduced along a route starting in Middle America and leading into Colombia, Venezuela, and eventually Brazil. "T'phaseolin cultivars in lowland South America may have been introduced directly from the Andes or indirectly by European immigrants. In the southwestern U.S.A., most of the cultivars showed an 'S'phaseolin, confirming the Middle American origin of these cultivars, as suggested previously by the archaeological record. In northeastern U.S.A. and Canada, the 'T" and 'C" phaseolin types were more frequent than the "S" phaseolin cultivars. While most of the former were possibly introduced into that region by European immigrants, most of the latter may have been introduced by the pre-Columbian Indian populations. Seed size analysis revealed that 'T" or "C" phaseolin cultivars had significantly larger seeds than 'S" phaseolin cultivars, as had been observed previously in Middle America and the Andes. The phaseolin types of commercial seed types and of early northeastern U.S. cultivars are discussed. |

This study aimed to test controlled levels of water deficiency in soil in mango trees, under microsprinkling irrigation, in semi-arid conditions, and to evaluate its effect in the productivity and fruits quality. The deficits were applied in the phases I, II and III of growth of the fruit, during the productive cycles of the mango tree in 2006 and 2007. The experiment in both cases was arranged in an entirely random design with 10 treatments and 3 repetitions, in the year I, and with 8 treatments and 3 repetitions in the year II. The values of soil water potential, of the treatments submitted to regulated deficit irrigation (RDI), were placed in the range of 0 to -0.011 MPa, showing that the soil humidity varied between the saturation and the field capacity, not characterizing deficit water condition. The average values of stem water potential (Ψstem) varied between -0.90 and -1.74 MPa, evidencing significant effect (p <0.05) just for T1 (without irrigation), T7 and T8 (RDI with 30% of the ETc in the phases II and III, respectively). Through the variance analysis, significant differences were not verified among productivity, number of fruits per plant and size of the fruit, in none of the experiments, what indicates the possibility of reduction of the water use in the irrigation of the mango tree without significant losses of productivity and fruit quality. |
