RESUMO
The aim of the present work was to evaluate the vegetative development of citrus rootstock seedlings cultivated under greenhouse conditions with two irrigation systems. The experiment was conducted at the Estação Experimental Agronômica , Universidade Federal do Rio Grande do Sul, located in Eldorado do Sul, Rio Grande do Sul, Brazil, from September 2003 to April 2004, totalizing 225 days of experimentation. The experimental design was a split-plot, in a 2x3 factorial, with 4 replications of 22 pots each. In the main plot the irrigation systems was evaluated (micro sprinkler and capillarity) and in the split-plot the citrus rootstocks [Trifoliate orange - Poncirus trifoliata (L.) Raf., 'C37' citrange - P. trifoliata x Citrus sinensis (L.) Osb. cv. Pêra and 'Rangpur' lime - C. limonia Osb.] were evaluated. The main result showed in conditions of greenhouse citrus rootstock seedlings presented a great vegetative development under irrigation by capillarity in relation to the micro sprinkler. The evaluated citrus rootstock seedling display different vegetative developments, where the 'C37' citrange was more vigorous.
