摘　　要：Waterlogging has occurred more frequently in recent years due to climate change,so it is a huge threat to crop yield and quality.Sweet cherry,a fruit tree with a high economic value,is sensitive to waterlogging stress.One of the most effective methods for enhancing the waterlogging tolerance of sweet cherries is to select waterlogging-tolerant rootstocks.However,the waterlogging tolerance of different cherry rootstocks,and the underlying mechanism remains uncharacterized.Thus,we first evaluated the waterlogging resistance of five sweet cherry rootstocks planted in China.The data showed that‘Gisela 12’and‘Colt’were the most waterlogging-sensitive and-tolerant among the five tested varieties,respectively.Oxygenation effectively alleviated the adverse impacts of waterlogging stress on cherry rootstocks.Moreover,we found that the waterlogging group had lower relative water content,Fv/Fm value,net photosynthetic rate,and higher antioxidant enzyme activities,whereas the oxygenated group performed better in all these parameters.RNA-Seq analysis revealed that numerous DEGs were involved in energy production,antioxidant metabolism,hormone metabolism pathways,and stress-related transcription factors.These findings will help provide management strategies to enhance the waterlogging tolerance of cherry rootstocks and thereby achieve higher yield and better quality of cherries.
