Tolerance to flooding during germination and early growth of weedy rice. [Abstract].

ABSTRACT: Flooding is an important method for weedy rice control. The reduction of the flooding effect ongermination and initial growth of weedy rice has been observed, which compromise the efficiency of flooded rice systems. The objectives of this study were to establish a methodology for the selection of weed rice populations with flooding tolerance, to evaluate the expression of genes associated to flooding in cultivated rice, and to investigate the effect of temperature and soil depth on tolerance to flooding in weedy rice.
