Plants typically adapt to hypoxia stress through various anatomical adjustments. Gas space formation in roots and/or leaves helps plants to deliver oxygen. Nitric oxide (NO) triggers aerenchyma formation in the plants. In the current study, we evaluated the effects of sodium nitroprusside (SNP, as a donor of NO) on strawberry under waterlogging conditions. ‘Albion’ cultivar strawberry plants were planted in pots. At 1 month after planting, plants underwent waterlogging stress by placing pots within plastic containers filled with either water or a 100-μmol SNP solution. The waterlogging condition was applied to the plants 2 h after SNP treatment. Control plants were kept under optimal soil moisture conditions. Some of the plants were delicately uprooted at 1 and 2 days after causing the stress and a 14-day recovery period was followed under well-drained conditions. Waterlogging stress depressed strawberry growth and hampered chlorophyll biosynthesis. The SNP treatment improved the growth, cortical cell expansion, and xylem conduit diameter under waterlogging conditions. Moreover, SNP increased the fruit quality properties and fortified the durability of spongy parenchyma in unstressed scenarios while specifically hindering spongy cells from amplifying gas formation during stressful periods.
