Seedlings of beans (Phaseolus vulgaris), corn (Zea mays), and tomatoes (Lycopersicon esculentum) were grown in the greenhouse and then exposed to controlled freezing conditions in a growth chamber. Variables were adjusted to determine the influence of plant water potential, freezing time, and external dew formation on the seedlings' susceptibility to frost injury. Freezing, detected visually an...

INTRODUCTION Common beans {Phaseolus vulgaris), owing to their nutrient-dense attributes, offer a potential to be developed as multiple-use products. However, in general, the consumption of beans has rarely gone beyond traditionally processed bean products and their uses. The reason for this stagnancy in the growth of processed bean consumption may be linked to 2 antinutritional factors found i...

Introduction: Snap bean is a vegetable cultivated by small farmers in some mountainous and hillside regions of Colombian. Since the research of snap bean has not had the same importance as common beans in Colombia, little competitive varieties, compared to the quahty of the Blue Lake variety have been released, with a culti-variety with low tolerance to the biotic constraints of the tropic (Sil...

The purpose of this research was to elucidate the genetic control of orange corona color in carioca common beans (Phaseolus vulgaris). We made four crosses between carioca group cultivars that differed in respect to the presence or absence of an orange hilum corona color. The F2, F3, F1BC11, F1BC21, F2BC11 and F2BC21 phenotypic segregations were evaluated with a chi-square test which fitted wit...

The interaction between polygalacturonase-inhibiting proteins (PGIPs), produced by plants, and endopolygalacturonases (PGs), produced by fungi, limits the destructive potential of PGs and can trigger plant defense responses. This study aimed to i) investigate variation in the expression of different common bean (Phaseolus vulgaris L.) genotypes and its relationship with resistance to white mold...

Identity recognition systems allow plants to tailor competitive phenotypes in response to the genetic relatedness of neighbours. There is limited evidence for the existence of recognition systems in crop species and whether they operate at a level that would allow for identification of different degrees of relatedness. Here, we test the responses of commercial soya bean cultivars to neighbours ...
