    Evaluating the post flooding recovery recovery potential and growth response of different Solanum Aethiopicum (shum) genotype

    The increasing occurrence of flooding events due to climate change poses a serious threat to crop production in sub-Saharan Africa, where Solanum aethiopicum Shum serves as an important leafy vegetable for food, nutritional and income security. This study evaluated the post-flooding recovery potential and growth responses of three Solanum aethiopicum Shum genotypes E11, E15, and E16 under controlled flooding conditions at Uganda Christian University. A randomized split plot design was used, subjecting plants to two weeks of partial submergence followed by recovery monitoring for a period of 14days. Results revealed significant genotypic variations in recovery time and, survival rates as measured using physiological parameters (such as chlorophyll content), and morphological traits (including leaf area, root length, and biomass accumulation). Genotype E11 exhibited the fastest recovery and highest survival rate (99.17%), while E16 demonstrated superior biomass production and root development. Analysis of the physiological traits showed that E15 and E16 maintained higher chlorophyll content during the recovery phase, indicating efficient restoration of photosynthetic capacity. Morphological recovery strategies differed, with E11 focusing on fewer but larger leaves, and E15 and E16 were favouring new leaf proliferation. These findings highlight the genetic diversity in flooding tolerance among Solanum aethiopicum Shum genotypes and underscore the potential for breeding flood-resilient cultivars to ensure food security in flood-prone regions.
