This research had as objective to evaluate the root system and development of citrus plants, originated from open and protected nursery systems. The roots were evaluated by the trench profile method with six replications for each nursery system, applying the SIARCS 3.0 software to determine root amount and distribution. Twenty plants were selected to evaluate vegetative development. A randomized design and the test t of Student were used for statistical analysis. The plants originated from open nursery system were superior to those from screen house regarding the root effective distance in the inter-rows and total amount of roots. The diameter and volume of the canopy were superior for plants originated from open nursery system.
