“…The pigment concentrations in the leaves of plants are closely associated with photosynthesis. Many previous studies have found that the Chl a, Chl b, and Car contents usually decline under flooding conditions, along with a reduction of photosynthesis [15,49,61]. However, the Chl a, Chl b, and Car contents in this study were unchanged, which could ensure the normal operation of photosynthesis.…”

Salix viminalis L., a dioecious species, is widely distributed in riparian zones, and flooding is one of the most common abiotic stresses that this species suffers. In this study, we investigated the morphological, anatomical, and physiological responses of male vs. female plants of S. viminalis to flooding. The results showed that the plant height and root collar diameter were stimulated by flooding treatment, which corresponded with higher dry weight of the stem and leaf. However, the dry weight of the underground part decreased, which might be due to the primary root having stopped growing. The little-influenced net photosynthesis rate (Pn) under flooding treatment could guarantee rapid growth of the aboveground part, while the unaffected leaf anatomical structure and photosynthetic pigment contents could ensure the normal operation of photosynthetic apparatus. Under a flooding environment, the production ratio of superoxide free radical (O2∙-) and malondialdehyde (MDA) contents increased, indicating that the cell membrane was damaged and oxidative stress was induced. At the same time, the antioxidant enzyme system, including superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and ascorbate peroxidase (APX), and osmotic adjustment substances, involving proline (Pro) and solute protein (SP), began to play a positive role in resisting flooding stress. Different from our expectation, the male and female plants of S. viminalis performed similarly under flooding, and no significant differences were discovered. The results indicate that both male and female plants of S. viminalis are tolerant to flooding. Thus, both male and female plants of S. viminalis could be planted in frequent flooding zones.

“…Under waterlogging, O 2 in the soil is rapidly depleted, resulting in hypoxic or anoxic conditions (Kuai et al, 2015; Shaw and Meyer, 2015). Anoxic conditions will cause crop physiological drought responses such as wilted leaves (Wang, 2010); induce anaerobic respiration, thereby rendering the energy supply insufficient and increasing the content of toxic substances such as lactic acid, alcohol, and reactive oxygen species (Jackson and Ram, 2003; Mustroph and Albrecht, 2007; Zhou et al, 2017; Andrade et al, 2018); and improve the balance of endogenous hormones, such as by increasing the contents of abscisic acid and ethylene (Wang, 2010; Zhang et al, 2016b). The consequences of anoxic conditions include limited photosynthesis and nutrient uptake (Hocking et al, 1987; Bange et al, 2004) and endangered normal growth of cotton and boll formation, which result in a decreased yield (Christianson et al, 2010; Kuai et al, 2015).…”

The objectives of this study were to determine the influence of waterlogging alone, drought alone, and alternating drought and waterlogging on cotton (Gossypium hirsutum L.) yield and yield components. Water deficit and waterlogging experiments were conducted at the flowering and boll‐setting stages of cotton. The lint and cottonseed yields were reduced after waterlogging alone, drought alone, and alternating drought and waterlogging. The lint and cottonseed yields under alternating drought and waterlogging were greater than those under drought alone. When alternating drought and waterlogging, the drought stage decreased the lint and cottonseed yields, whereas the waterlogging stage had a compensatory effect. The decrease in the number of opening bolls might be the major reason for the observed decrease in lint and cottonseed yields. Waterlogging alone, drought alone, and alternating drought and waterlogging all led to an increase in the proportion of the boll wall biomass and a decrease in the proportion of the fiber biomass of cotton bolls. The proportion of the seed biomass of cotton bolls always decreased, except under alternating drought and heavy waterlogging in 2015. The fiber/seed biomass ratio decreased, except under drought alone in 2015. These findings might provide data to support the prevention of cotton yield loss under drought and waterlogging.

“…LDH and ADH are mainly involved in anaerobic metabolism, under hypoxia environment, LDH is first activated to produce lactate, ADH is subsequently activated and then ethanol metabolism is started (Xu et al 2016). Previous studies indicated that the activity of LDH, ADH, PDC in submerged parts of crops were higher than normal growth environment, which improve the acclimation ability of the crops to hypoxia stress (Kato-Noguchi and Morokuma 2007;Yin 2009;Ou et al 2017;Zhou et al 2017;Du et al 2018). Under hypoxia stress, maize seedlings produce glycolysis and fermentation-related transitional peptides and anaerobic peptides such as LDH, ADH, and PDC.…”

Waterlogging stress is one of the most natural stress, which due to excessive rainfall or low-lying terrain, and limits crop growth and yield. Our objective was to study the morpho-anatomical and physiological characteristics of a paired near-isogenic lines of waxy corn under waterlogging stress. This experiment was implemented in pots with a paired of near-isogenic lines differing in waterlogging tolerance: Zz-R (waterlogging-resistant) and Zz-S (waterlogging-sensitive). Root morphology features, anaerobic respiratory enzyme activity, and tissue anatomical characteristics were measured at 0, 2, 4, 6 and 8d in the control and waterlogging conditions. The result indicated that waterlogging induced a decrease in the root length, volume and surface areas of the two waxy corn inbred lines, the total root length, root volume, and root surface area of the Zz-R showed less reduction than the Zz-S. Waterlogging stress influenced significantly by the parenchyma cells in cortex of root between Zz-R and Zz-S. Zz-R can also maintain a higher level of anaerobic respiratory enzyme activity under waterlogging stress. The different reaction between the paired near-isogenic lines may be responsible for higher tolerance of Zz-R than Zz-S. These results can provide a certain theoretical basis of the resistance evaluation and breeding to the resistant varieties.
