“…However, when the seeds of lentil and faba bean were exposed to low oxygen partial pressures at 1.0 and 2.5 kPa oxygen for 6 days, the seeds of both legume species had low percent germination at <17 % ( Fig. 6 ), similar to that shown for soybean ( Tian et al 2005 ; Nakajima et al 2015 ). Therefore, anoxia and hypoxia experiments give an indication that oxygen availability to seeds plays a key role for waterlogging tolerance in small seeds over large seeds when partially buried in the first several millimetres of the soil.…”

“…Crop species also show different responses to hypoxic conditions during germination ( Al-Ani et al 1982 , 1985 ; Nakajima et al 2015 ; Yasin and Andreasen 2016 ). Seeds of wheat and field pea geminated at a very low oxygen partial pressure of 0.1 kPa but seeds of flax ( Linum usitatissimum ) failed to germinate under the same conditions ( Al-Ani et al 1985 ).…”

Legume seeds, when relay sown following rice, may suffer from soil waterlogging and the associated hypoxia or even anoxia. This study evaluated the tolerance of grain legume species, grass pea (three genotypes), lentil (two genotypes), faba bean (two genotypes) and field pea (one genotype), to soil waterlogging in a glasshouse, to anoxia and hypoxia in temperature-controlled room at germination and seedling stages. Changes in oxygen in the surface layers of soil, with time after waterlogging, were measured by microelectrode profiling. The soil profiling showed that soil oxygen declined and then stabilised by the fourth day after waterlogging and oxygen was not detected at 8 mm below the soil surface. Germination of seeds under waterlogging for up to 12 days and seedling survival after the soil was drained for up to 36 days, were measured in pot experiments. Seed germination and/or survival in anoxia (N2-flushed solutions) and hypoxia (1.0 and 2.5 kPa oxygen) were evaluated, and so were post-anoxia or post-hypoxia recoveries, all in comparison with aerated controls. Lentil had higher seedling emergence (55%) than the other species during soil waterlogging. However, lentil had lower seedling survival (9%) than grass pea (28%) during recovery following soil drainage. Grass pea seeds were more tolerant of anoxia and of hypoxia than the seeds of the three other species. In conclusion, grass pea, with higher percent germination and seedling survival during recovery, is more tolerant to waterlogging and subsequent soil drainage than the three other grain legume species. Grass pea was also more tolerant of hypoxia and of anoxia at the seed germination stage. These findings demonstrate the superior waterlogging tolerance of grass pea in relay sowing, as compared with the other grain legumes.

“…Similar results were found by Sung (1995) in a study with soybeans wherein water excess for longer than 24 and 48 hours reduced emergence by 50% and 100%, respectively. Therefore, water excess in sunflower crops during germination might be harmful right after sowing, as already seen for soybean seedlings (Nakajima et al, 2015). This might be explained by an increase in respiration rate and enzyme activity after the first seed imbibition peak, causing a high demand for O2 what potentiates seed damages (Orchard & Jessop, 1984).…”

“…Plant emergence of sensitive species such as wheat, soybeans, and maize is strongly affected by water excess (Lucas et al, 2015;Zaidi et al, 2012;Sung, 1995;Nakajima et al, 2015). High air temperatures have a major effect on seed germination of these species (Zaidi et al, 2012;Nakamura et al, 2012;Nakajima et al, 2015), however, few species have evolved to germinate and grow in anoxic environments (Orchard & Jessop, 1984). Rice (Oryza sativa L.) is a good example of it for being able to germinate under anoxic conditions, as amylase enzymes break down the starch under O2 absence (Yamauchi et al, 2013).…”

Sunflower crops are grown in different regions worldwide. However, the stress caused by water excess in the soil impairs this crop growth and yield. The aim of the present study was to determine the response of sunflower plants to long periods of water excess during initial development stages. Water excess treatments were applied at the initial development of these plants at the sowing day, three days after sowing, at plant emergence, and at V2 and V4 stages. The treatments had different duration periods (0, 48, 96, 144, 192, and 240 hours) and were applied at three sowing dates. The current experiment is factorial and was carried out according to a completely random design. Two plant pots, treated under greenhouse conditions, made up the experimental units. Plant emergence, leaf area, plant height, shoot dry mass, maximum root length, main root length and root dry mass were herein assessed. Water excess is more harmful to sunflower plants during the sowing-emergence period. It substantially reduces emergence, plant density, shoot and root growth, even after 48-hour stress. Moreover, water excess leads to the formation of adventitious and secondary roots.

“…Germplasms of wild soybeans are thought to be useful materials for breeding to enhance stress tolerance, because much of the diversity in cultivated soybeans has been lost during the genetic bottleneck that occurred during domestication (Kaga et al, 2012;Lam et al, 2010). In fact, accessions that still resemble their wild relatives have high tolerance to various stresses; these include Peking, which tolerates pre-germination waterlogging (Muramatsu et al, 2008;Nakajima et al, 2015); JWS156-1, which tolerates salt stress (Hamwieh & Xu, 2008); and PI468917, which has high drought tolerance (Seversike et al, 2014). Sakazono et al (2014) reported that some wild soybeans also had a high ability to develop roots under waterlogging during early growth stages.…”

Soybean is often damaged by hypoxia caused by waterlogging at the seedling stage. Hypoxia severely inhibits root development and retards plant growth. We aimed to clarify phenotypic variation in root development under hypoxia condition at the seedling stage using diverse soybean accessions. Root development in 162 accessions was evaluated in hydroponic culture. Substantial changes under hypoxia were investigated by means of WinRHIZO analysis before and after the treatment. We found significant phenotypic variation in hypoxia tolerance in root among the 162 accessions. A principal components analysis indicated an association between hypoxia tolerance and the country of origin. We found three new accessions which have a high ability to develop roots under hypoxia (Kokubu 7, Maetsue zairai 90B, and Yahagi). Root development in selected accessions was also evaluated in soil culture. Root development levels in hydroponic and soil culture were significantly correlated. These results will provide important information on waterlogging damage in regions where waterlogging occurs. The three accessions with hypoxia-tolerant roots might be useful for genetic improvement of waterlogging tolerance of modern soybean varieties.
