Resumo: | The pre-germinated rice growing system demands genotypes with a higher capacity of initial development in an anaerobic environment. Having in mind the need for better knowing the characteristics of the cultivars El Paso 144, BR IRGA 409, BR IRGA 410, IRGA 416, IRGA 417 and Bluebelle, this paper reports a comparative study of the enzymatic activity of glutamate oxaloacetate transaminase (GOT), esterase (EST), and malate dehydrogenase (MDH), in the rice seedling shoots through electrophoresis. The treatments consisted in germination and development of the seedlings during 14 days at the temperatures of 20, 25 and 30oC under both aerobic and anaerobic conditions. The analysis of the electrophoresis gels leads to conclude that: a) The IRGA 417 seedlings stands out against the other cultivars because of its higher level of activity of the enzymes studied under the anaerobic treatment at the temperature of 20o C; and b) The great variability found in the enzymatic systems studied for the different genotypes and treatments used allow to recommend that studies of genotype x environment interaction use biochemical systems, in order to assist in the search for genotypes that are able to overcome environmental stress. |

O sistema de cultivo de arroz pré-germinado demanda genótipos com maior capacidade de desenvolvi- mento inicial em ambiente anaeróbico. Com o intuito de contribuir para o conhecimento das características dos genótipos El Paso 144, BR IRGA 409, BR IRGA 410, IRGA 416, IRGA 417 e Bluebelle, foi realizado um estudo comparativo das enzimas glutamato oxaloacetato transaminase (GOT), esterase (EST), e malato desidrogenase (MDH) na parte aérea de plântulas de arroz através de eletroforese. Os tratamentos consistiram de germinação e desenvolvimento das plântulas durante 14 dias sob as temperaturas de 20, 25 e 30oC, em condições de aerobiose e de anaerobiose. A análise dos géis permitiu concluir que as plântulas de IRGA 417 destacam-se das demais por apresentarem maior atividade das enzimas estudadas no tratamento anaeróbico com temperatura de 20 oC; e que a grande variabilidade das isoenzimas específicas em diferentes genótipos permite recomendar que os estudos de interação genótipo x ambiente utilizem sistemas bioquímicos para auxiliar na identificação de genótipos capazes de superar estresses ambientais.
