| الوصف: | Hydromorphic soils have a low drainage capacity and are used mainly for the cultivation of irrigated rice.This condition favors the development of anaerobic microorganisms that produce phytotoxic substances. The objective of thisstudy was to evaluate the response of rice mutants to the phytotoxicity caused by butyric acid under anaerobic conditions. Theexperiment consisted of four treatments arranged in a randomized block design. Plants of 40 families were grown in ahydroponic system and the measured variables were root length and length of aerial part (LAP), number of roots (NR) androot dry matter (RDM) and aerial part dry matter (DMAP). The analysis of variance was performed, the relative performancecalculated and linear regressions were fitted. Only the treatment effect for NR and effect of interaction for LAP were notsignificant. Root length was most affected by the acid and the regressions expressed positive as well as negative effects for acidtolerance in the mutant families. |
