Abstract: (33 Views) |
The stress caused by waterlogging significantly impacts the growth intensity and performance of various plant species. This study investigated the effects of different levels of abiotic waterlogging stress on several morphological and biochemical parameters of Rosa chinensis “Old Blush” under greenhouse conditions. The results indicate that the response of the Chinese rose to waterlogging stress varies depending on the stress level and duration when compared to the control group. A noticeable reduction in leaf chlorophyll content, along with an increase in enzyme activity and leaf EC content were observed under waterlogging conditions. The response of the stomata exhibited a trend toward closure with increased duration of waterlogging stress. Overall, these findings enhance our understanding of the biochemical responses in leaf cells related to carbon dioxide absorption through plant stomata. This knowledge may contribute to a better understanding of the mechanisms of resistance to waterlogging stress in the Chinese rose. |
