“…This is the main reason for the rapid decline of photosynthetic rate in WL-sensitive plants and the constant photosynthetic rate in WL-tolerant plants in the early stage of hypoxia stress. But after a long time of hypoxia treatment, the decrease of Fv/Fm and qp suggested that the PSII reaction centers were largely damaged and closed possibly because ROS accumulation destroyed the chloroplast structure and photosynthetic enzymes (Cherif et al 2010, Wu et al 2015, Keller et al 2019. Here, the limitation of maximal photochemical efficiency could be explained by SPAD and spectral curve characteristic parameters.…”

The objectives of the present study were to compare the dynamic of the growth and photosynthetic characteristics of cotton varieties contrasting in waterlogging (WL) tolerance when subjected to hypoxia stress. The growth of the WL-sensitive genotypes was notably inhibited by WL, mainly as a result of a significant reduction in the net photosynthesis (PN) after two days of hypoxia treatment; in the tolerant varieties, no significant changes in PN were observed until 8 d after hypoxia onset. The intercellular CO2 concentration and maximal photochemical efficiency of PSII significantly declined, and the nonphotochemical quenching increased in the sensitive varieties. Infrared thermography showed that a low stomatal conductance resulted in an increased leaf temperature under hypoxia stress. Spectral image analysis suggested that the pigment content and water content rapidly decreased in the leaves of the sensitive varieties. It is concluded that maintaining stomatal opening through the interaction of ethylene and abscisic acid may be an important strategy to improve waterlogging tolerance in cotton.Additional key words: chlorophyll fluorescence; Gossypium hirsutum; hyperspectral image; infrared thermal image.

“…Previous investigations observed that the grain yield after seedling waterlogging much lesser than that of the late growth stages (Wu et al, 2015), because waterlogging inhibited the growth of early tilling and disrupted the suitable establishment of the large spikes (Malik et al, 2002;Dickin et al, 2009), and it affected the long-term growth and physiology of the wheat (Malik et al, 2002). However, other studies foundthat seedling waterlogging did not significantly affect the grain yield because of thelong-term recovery after waterlogging (Cannell et al, 1980;Dickin et al, 2009).…”

“…Our results were consistent with their experimental results. In addition, whether grain yield is substantially reduced because of seedling waterlogging remains controversial (Dickin et al, 2009;Wu et al, 2015). Further research is thus necessary to determine the effects of seedling waterlogging on wheat yield in the YR.…”

“…In this area, precipitation normally exceeds the water requirement of wheat, and is irregularly distributed on spatial and temporal scales. Moreover, a rice-wheat rotation system is generally conducted in the YR, resulting inwater-saturated soil because of frequent rainfalls and excessive irrigation during the rice-growing season (Wu et al, 2015). Because of the increase of extreme climate eventsin the recent years, the frequency of rainfall intensity has increased and this increases the frequency of waterlogging (Schumacher & Johnson, 2006;Shao et al, 2013).…”

“…At the agronomic level, typical responses to waterlogging include decreased plant height; inhibited antioxidant capacity of leaves and roots; relatively low levels of photosynthesis, respiration, and transpiration; and reduced growth of the roots and shoots; and reduced tillers, kernel number, and grain yield (Brisson et al, 2002;Jiang et al, 2006;Olgun et al, 2008;Hossain & Uddin, 2011). In addition, the severity of waterlogging's unfavourable effectson wheat growth depends on several factors, such assoil and weather conditions (Setter & Waters, 2003), cultivars grown (Dickin et al, 2009;Haque et al, 2012), cultivation technologies (Wu et al, 2013), growth stage of the plants (Shao et al, 2013;Wu et al, 2015), depth of water levels (Malik et al, 2001), and severity and duration of waterlogging (Collaku & Harrison, 2002;Malik et al, 2002). …”

Waterlogging is a major constraint on wheat (Triticum aestivum L.) production, especially in the Yangtze River Basin of China (YR). A container experiment was designed to investigate wheat-seedling growth and short-term recoveryin response to waterlogging. Cultivars commonly grown in theYR from three different decades, namely, Yangmai 1 (1970s), Yangmai 158 (1990s), and Yangfumai 4 (2010s), were selected. Seedling waterlogging significantly postponed leaf development, as well as decreased the number of tillers and adventitious roots per plant, seedling height, leaf area, specific leaf dry weight, shoot dry weight, root dry weight, and root/shoot ratio. After a 20-day recovery phase, the leaf stage, seedling height, and root/shoot ratio recovered to the control level, whereas the adverse effects of waterlogging on the number of tillers per plant, leaf area, and shoot dry weight intensified. Significant differences were found in seedling growth among the three wheat cultivars. Yangfumai 4 showed the highest number of adventitious rootsper plant and the highest specific leaf dry weightbut the lowest seedling height, leaf area, and dry weights of shoots and roots. However, Yangfumai 4 showed the lowest percentage decrease in all growth parameters after both waterlogging and recovery. These results suggested thatimprovement inadventitious root numberper plant and specific leaf dry weight may be indicators ofresistance to waterlogging in wheat.
