Simple Summary: This research article investigates the ploidy's impact on daylilies' (Hemerocallis spp.) response to water deficit conditions. By analyzing the morphological and physiological changes in diploid and tetraploid plants under drought stress, this study aims to elucidate the adaptive mechanisms that contribute to their differential tolerance levels. The results reveal distinct responses in the chlorophyll content, flavonoid accumulation, and nitrogen balance between the two ploidy groups, highlighting the superior stress resistance of tetraploid daylilies. The conclusions emphasize the importance of considering ploidy in understanding plant responses to drought stress and suggest the potential for cultivating drought-tolerant varieties to mitigate water scarcity challenges. This study's insights hold significant value for society by informing strategies for sustainable floriculture, enhancing greenery resilience to climate change, and promoting water-efficient plant breeding practices. This study aimed to understand the differences in the performance of diploid and tetraploid daylily cultivars under water deficit conditions, which are essential indicators of drought tolerance. This research revealed that tetraploid daylilies performed better than diploid varieties in arid conditions due to their enhanced adaptability and resilience to water deficit conditions. The analysis of the results highlighted the need to clarify the specific physiological and molecular mechanisms underlying the enhanced drought tolerance observed in tetraploid plants compared to diploids. This research offers valuable knowledge for improving crop resilience and sustainable floricultural practices in changing environmental conditions. The morphological and physiological parameters were analyzed in 19 diploid and 21 tetraploid daylily cultivars under controlled water deficit conditions, and three drought resistance groups were formed based on the clustering of these parameters. In a high drought resistance cluster, 93.3% tetraploid cultivars were exhibited. This study demonstrates the significance of ploidy in shaping plant responses to drought stress. It emphasizes the importance of studying plant responses to water deficit in landscape horticulture to develop drought-tolerant plants and ensure aspects of climate change. [ABSTRACT FROM AUTHOR] |
