needed as replicates for studying tolerance genes in rootstock breeding programs ( Falconer and Mackay, 1996 ). Germination is an important stage in the life cycle of species growing under stress conditions, because this stage determines the soil

more costly than NH 4 + assimilation. Common bean responds to osmotic stress by osmotic adjustment, which enhances stress tolerance ( Sassi et al., 2010a , 2010b ). A previous study with common bean cultivars showed the relative sensitivity of cv

, ‘Latitude 36’ under 8 d drought stress; lane 7, ‘Premier’ under 8 d drought stress. All lanes were loaded with 20 μg buffer-soluble protein. Our results suggest that dehydrin polypeptides of 16 and 23 kDa play a role in drought tolerance of bermudagrass. The

increased water deficit stress tolerance by reducing g S in bedding plants ( Park et al., 2016 ; Waterland et al., 2010a , 2010b ). Stress tolerance can be enhanced by imposing a single stressor in advance of later stresses. Earlier stress can result in

). It should be noted, however, that the sensitivity or tolerance to stress can be uncoupled from germination rate or uniformity. In other words, sensitivity to stress as displayed by a loss of germination ability (i.e., reduced germination percentage
