“…It was noted that the yellowing of leaves will start on the older leaf and the leaf tips will start to yellow, followed by the leaf blade. This observation is also similar to Shin et al (2016) observation that waterlogging at the early growth stage of maize, leaves turned yellow and the lower ones started senescing. This yellowing of leaves is an indication of chlorophyll reduction due to waterlogging.…”

Background: This study aimed to determine the effects of different waterlogging duration imposed at the V2 leaf stage and assess the impact of waterlogging on maize growth during the recovery period, identify susceptible and tolerant lines and traits conferring tolerance to waterlogging at the early seedling stage. Methods: The study was arranged in a Split-plot RCBD and replicated three times. Intercharacter and waterlogging durations to maize growth parameters were correlated to determine the degree of the linear relationship using Pearson’s product moments correlation and simple linear regression analysis. Result: The result shows that the different waterlogging durations negatively influenced the maize growth parameters regarding plant height and root length. These parameters became shorter and did not recover after waterlogging stress was removed. Therefore, plant height and root length are traits sensitive to waterlogging stress. The USM Var 10, BRK and T. Monkayo obtained a high degree of leaf greenness, heaviest shoot and root dry matter compared to other evaluated maize lines. Maize with greener leaves, taller plant height, longer root length and high total dry matter accumulation could be a good criterion in selecting a parent material in the maize waterlogging breeding program.

“…Under normal soil conditions, this trait shows poor expression, but, there is significant increase in this traits (Shah et al, 2012, andZaidi et al, 2007) (Campbell et al, 2015 andShah et al, 2012). Foliar senescence was also approved to be the most common and immediate symptom of water-logging (Shin et al, 2016). Further, days to 75% dry husk and days to silking correlated to yield which was partly in accordance with the findings of under ESM stress.…”

A critical assessment of 32 maize hybrids with two replications for excessive soil moisture stress (ESM) was carried out during Kharif 2019-20. The plants were exposed to waterlogging stress for 12 days at the flowering stage by maintaining a water level of 3-5 cm. High genotypic coefficient of variation (GCV) and phenotypic coefficient of variation (PCV) were attained for maize plants with adventitious roots and senescence percentage after stress. High heritability along with high genetic advance was determined for number of plants with adventitious roots, senescence percentage, plant height and 100 kernel weight. Plant yield depicted a highly significant positive genotypic and phenotypic correlation with plant height, ear height, number of plants with adventitious roots and number of kernels per row, along with a significant negative correlation with senescence percentage. Kernels per row and plant height manifested the highest positive direct effect on plant yield at phenotypic and genotypic levels, respectively, reflecting that the characters can be considered for plant selection under ESM stress.

“…Waterlogging causes root hypoxia, thus indirectly affecting the growth and development of shoots (Qi et al, 2012). Waterlogging inhibited the growth of plant shoots which resulted in the reduction of plant height (Shin et al, 2016). Waterlogging at seedling stage inbibits seedling growth whereas reduction in plant height is directly related to flooding duration (Liu et al, 2013).…”

“…In response to waterlogging stress, maize root cells cleave to form aeration tissue for maintaining oxygen diffusion and high absorption efficiency (Zaidi et al, 2003). Most of the previous studies which are related to aboveground response of maize to waterlogging showed that plant height, dry weight and leaf photosynthesis severely got affected by waterlogging (Ren et al, 2016b;Shin et al, 2016;Wang et al, 2012). Lipid peroxidation caused chloroplastic membrane destruction is one of the responses of plants to waterlogged conditions.…”

Maize is extremely sensitive to waterlogging stress. A pot experiment was conducted to study the morpho-physiological characteristics of 18 differrent maize cultivars (widely grown in South China) under waterlogging stress at seedling stage. Results showed that maize shoot growth was inhibited in terms of plant height and dry weight whilst leaf chlorophyll contents were also decreased under waterlogging stress. Root length, root hairs, root surface area and root volume were also declined under waterlogged conditions. Furthermore, activity of antioxidants i.e., superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) were increased considerably under waterlogging stress compared to control. The soluble protein content also increased in some maize cultivars whereas malondialdehyde (MDA) contents were found to be decreased in some cultivars that may be due to higher antioxidant enzyme activities. Furthermore, the principal component analysis (PCA) showed that the coefficients of comprehensive indices (Z) for protein contents, SOD, POD and CAT were higher in Z1, the soluble protein content and MDA content in Z2 while the SPAD and F v /F m values in Z3 were remained higher than other parameters.
