Abstract Background In recent years, the alternating occurrence of high temperature and waterlogging disasters in South China from July to August has seriously reduced the yield of single cropping rice. Studying the changes in anatomical structure of the rice root system could provide theoretical basis for understanding the mechanisms of high temperature and waterlogging stress in rice plants.Results To examine the effects of high temperature and waterlogging stress on root anatomical structure of rice at booting stage, six treatments of rice plants were set up: high temperature stress (T1), high temperature × light waterlogging stress (water depth of 10 cm; T2), high temperature × heavy waterlogging stress (water depth of 15 cm; T3), light waterlogging stress (water depth of 10 cm; T4), heavy waterlogging stress (water depth of 15 cm;T5), and regular irrigation with shallow water (water depth of 0–5 cm) except at harvest maturity (CK). The interaction of high temperature and waterlogging stresses at the booting stage promoted earlier formation of the aeration tissue in rice roots and had a certain degree of continuity. High temperature inhibited the increase in rice root diameter, stele diameter, thickness of the outer root layer, and vessel diameter. Compared to the CK, root diameter and stele diameter under high temperature stress (T1) were decreased by 29.09% and 15.28%, respectively, at the booting stage, whereas high temperature × heavy waterlogging (T3) affected only the vessel diameter, reducing it by 14.11% compared with that in the CK. The increase in rice root diameter, stele diameter, thickness of the outer root cortex layer, and vessel diameter were inhibited under stress at the booting stage. Compared with high temperature stress, the interaction of high temperature and waterlogging stress alleviated the inhibiting effect of the changes in the root system on water and nutrient transport.Conclusion Therefore, under high temperature weather conditions after a rainstorm, water level of the surface of paddy fields should be maintained at about 10–15 cm for 5 days to alleviate the effect of high temperature on rice growth and reduce the loss of nitrogen and phosphorus.
