TAVARES, Antonio C. S. et al. Effects of waterlogging on physiological indexes of sugarcane. []. , 41, 1, pp.241-250. ISSN 0871-018X.  https://doi.org/10.19084/RCA17036.

In sugarcane cultivation, waterlogging is an acute problem particularly where surface drainage facilities are not adequate. Physiological indexes were studied in sugarcane (Saccharum sp. cultivar RB 867515 genotype) at normal and logging water. A greenhouse experiment was conducted in a randomized blocks design, arranged in factorial scheme (5 x 3 + 1) x 4, which are, 5 demotion velocities of the water table (30 cm depth in 3, 6, 9, 12 and 15 days) and, 3 plant growth stages (67, 210 and 305 days after planting - DAP) + a control (irrigation without waterlogging) with 4 replications. The analysis results indicated that logging water stress condition to different downgrade rate of water table did not interfere on average absolute growth rate, liquid assimilation rate and growth rate of sugarcane. The highest relative growth and leaf area ratio were obtained when water logging soil condition occurs at 210 DAP.
