Changes in root anatomical structures at successive cycles of selection (cycle 1 to cycle 18, alternating) were observed in the study of maize (Zea mays L. cv. Saracura-BRS 4154) capable to survive and produce in temporarily flooded soils; this cultivars was developed by the Maize and Sorghum National Research Center through stratified phenotypic recurrent selection for cultivation wetland soils. Field trial was carried out and flooding of the soil was initiated at the six-leaf stage; the soil was flooded with water (20-cm deep) three times per week. Root sample was collected, fixed, and selected for observation in photon microscope. A gradual increase in the number of aerenchyma, the proportion of vascular cylinder, smaller metaxylem, and phloem and epidermis width, and a decrease in exodermis and cortex were observed in successive selection cycles. Such phenotypic changes impart the flood tolerance ability to this maize cultivar.

Four pigeon pea genotypes (ICPH-2431, PARAS, UPAS-120, H09-33) were raised in polythene bags filled with half kg soil + FYM manure mixture. Waterlogging, salinity and waterlogging + salinity treatments were given for 8 days and observations were recorded 1 day after removal from treatment in 20 and 40 day old plants. Significant decline in percent survival was observed under waterlogging and combined treatment in 20 and 40 day old plants. Decline in total sugar content and non reducing sugar content was observed under all three treatments in 20 and 40 day old plant leaves. In roots, an initial increase in total soluble sugar content was observed with waterlogging and salinity treatment. Non reducing sugar content also decreased under all the three treatments. An increase in sucrose synthase and alcohol dehydrogenase activity under all three treatments and formation of aerenchyma in roots under waterlogging and combined treatment was also observed. Waterlogging and salinity in combination was more deleterious compared to alone treatments. Roots were more sensitive to all the stresses as compared to leaves. ICPH performed best among all the genotypes.

“…Moreover, submergence also inhibits the diffusion of O 2 in order to prevent plant for doing aerobic respiration (Jackson and Ram 2003;Sauter 2013;Kato et al 2014). Pourabdal et al (2008) state that increasing the submergence period will gradually reduce the amount of soluble sugar. This is consistent with the results of this study that dissolved sugar levels tend to decline with the longer submergence period.…”

Abstract. Rachmawati D, Maryani MM, Kusumadewi S, Rahayu F. 2019. Survival and root structure changes of rice seedlings in different cultivars under submergence condition. Biodiversitas 20: 3011-3017. Submergence affects plant growth and fitness in natural and agricultural ecosystem. Plant survival to submergence is strongly influenced by the water level and duration of submergence. The objective of this study was to determine the survivalysiological and root anatomical changes of two rice cultivars seedlings to submergence The experiment used completely randomized design with three factors, cultivar (IR-64’ and ‘Inpara 5’), depth and duration of submergence. Depth of submergence consisted of 3 levels: without, partial and complete submergence. Fourteen days old seedlings were treated for 5, 10 and 15 days of submergence. The observed parameters were seedling survival, chlorophyll content, soluble sugar and starch content, plant biomass, and root anatomical structure. The results showed that seedlings survival of ‘IR-64’ and ‘Inpara 5’ decreased by increasing depth and duration of submergence. Increasing depth of submergence decreased chlorophyll content, soluble sugar content and plant biomass. Anatomically, depth and duration of submergence showed a greater increased in root cortex thickness, aerenchyma tissue diameter and the percentage of cortex to be aerenchyma of rice ‘IR-64’ and ‘Inpara 5’. Fifteen days of complete submergence significantly decreased seedlings survival and increased the diameter of aerenchyma in both ‘IR-64’ and ‘Inpara 5’.
