PHYSIOLOGICAL QUALITY IN BEAN SEEDS

The bean crop stands out because it is a species widely cultivated throughout Brazil. To achieve success in relation to its production and productivity is essential to establish an adequate stand, and thus crucial the use of seeds with good levels of physiological quality, since the propagation of the bean is via seeds. Physiological quality covers concepts related to the attributes of viability and vigor, which are commonly determined by methodologies that evaluate the performance of seed samples under controlled conditions. Bed Bugs attack the bean crop in the flowering and grain filling stages, compromising the quality of the seeds; the tetrazolium test detects bed bug damage, allowing the identification of whether it has reached the tissues of the embryonic axis.
