“…In these studies, the authors found respectively, a reduction in germination when the seeds were submitted to potentials of -1.0 and -0.8 MPa. Similar data were found when simulating osmotic potentials induced by mannitol and PEG on germination in seeds of the beetroot, from a potential of -0.4 MPa (MACIEL et al, 2015). In another study, Silva et al (2011) found that carrot seeds had little tolerance to water stress simulated by PEG, with a maximum limit for germination at a potential of -0.3 MPa.…”

“…The authors found that a decrease in osmotic potential reduced seedling dry weight from a potential of -0.5 MPa. A reduction also found in Maciel et al (2015), in seeds of the beetroot submitted to solutions of mannitol and PEG at a potential of -1.4 MPa, when the germination process was inhibited and normal seedlings were not found.…”

“…However, when using mannitol, there were normal seedlings from both seed lots up to a potential of -0.6 MPa, but with smaller lengths and less percentage germination than at the other potentials, reaching zero germination at -0.8 MPa. Maciel et al (2015) found that water deficit induced by solutions of PEG and mannitol at potentials of from -0.8 MPa, did not allow shoot development in beetroot, and noted only protrusion of the primary root.…”

“…In the literature, several vegetable species have been studied in relation to the effects of water deficit on germination and vigour, such as the lettuce (Lactuca sativa) (BERTAGNOLLI et al, 2003), carrot (Daucus carota) (SILVA et al, 2011), cucumber (Cucumis sativus) (MATIAS et al, 2015) and beetroot (Beta vulgaris) (MACIEL et al, 2015). However, for A. oleracea, information on the effects of water deficit on the germination process is nonexistent, which makes it necessary to understand the behaviour of this species when subjected to conditions of water deficit.…”

Water availability influences plant metabolism during the various stages of development, especially in the period between germination and seedling emergence. The aim of this study was to evaluate the effect of water deficit during the germination process on seeds of A. oleracea. The experiment was carried out in a completely randomised design, with four replications of 50 seeds. The treatments were arranged in a 5 x 2 factorial scheme, with the first factor consisting of the osmotic potentials (-0.2, -0.4, -0.6, -0.8 and distilled water for the potential 0.0 MPa) and the second factor consisting of two lots of seed. The germination test was carried out on substrates moistened with solutions of mannitol and polyethylene glycol (PEG 6000) at the various potentials, in a Biochemical Oxygen Demand (BOD) germinator at a temperature of 30°C and under constant light. The test was evaluated daily for 14 days, considering the seeds that had a root length equal to or greater than two millimetres as having germinated. The variables under analysis were germination, germination speed index, seedling length and seedling dry weight. The germination process of A. oleracea is compromised at water potentials of -0.2 MPa and -0.4 MPa when submitted to PEG and mannitol respectively. Seeds from Lot 1 were more tolerant to the water deficit than were those from Lot 2.
