Effect of water stress induced by PEG 6000 on in vitro germination of Phaseolus vulgaris L. cv. ‘ICA Pijao’ seeds
Journal Title: Biotecnología Vegetal - Year 2015, Vol 15, Issue 4
Abstract
The common bean (Phaseolus vulgaris L.) production has been very important in Cuba, however, several factors affect the yield of this crop and not all cultivars of beans respond the same way to the stressful conditions. The aim of this study was to determine the effect of water deficit induced by PEG 6000 on the cultivar ‘ICA Pijao’. The results showed that increasing concentrations of PEG 6000, reduced the percentage of P. vulgaris cv. ICA Pijao in vitro germination, which confirmed that this stressor agent could be useful to elucidate the physiological response and concentrations PEG 6000 to be used in bioassays to evaluate the plant response in this cultivar should be less than 18 %.
