Abstract
【Objective】This study was carried out to explore the effects of Polyethylene glycol(PEG-6000)stress on seed germination,seeding root ability and drought resistance condition of eight cultivars of fava bean.【Method】Different osmotic potential of PEG-6000(-0.09,-0.24,-0.43,-0.66,-0.85and-1.20 MPa)were used to simulate drought stress.The indicators of seed germination were measured and change rules were analyzed.【Results】With the increase of PEG-6000 concentration,the germination rate,germination vigor,germination index,growth of plumule and germ dry weight of the fava bean seeds decreased generally.Low concentration of PEG improved seed germination of some fava bean variety materials.As the drought intensified,seed germination rate,germination vigor and germination index decreased and the growth of plumule and radical were inhibited.【Conclusion】The suitable PEG-6000 concentration for drought resistance identification was 15%.The larger PEG-6000 concentration was,the more severely the seed germination and seeding root ability of fava bean were influenced.The comprehensive evaluation on drought resistance of fava bean according to subordination function method indicated thatthe drought resistance ability were ranked as Qinghai 13 Gadadou Lincan 9 Maya Qingcan 15 Lincan 6 Qinghai 12 Qingcan 14.
