ABSTRACT
This research determines the best nursery environment for the development of Schizolobium parahyba (Vell.) - Guapuruvu. Seeds germinated in substratum of vermiculite, and later were transplanted for plastic bags ( 12 x 21 cm), with fertilized substratum of vermiculite and sand (1:1). After acclimatization, the plants were assigned to three environments : (1) whole sunny day; (2) half sunny day, and (3) all shaded day. At each 15 days fertilizations were accomplished, and 3 samples of each environment were withdraw at 15th, 30th, 60th, 90th and 120th days. The variables analyzed were : Height of the aerial part, Diameter, Green weigh and Waterless weigh of aerial and roots parts. The results indicates that the environmental conditions (2) presentes larger averages on variables and that the plants of this species grow better in nursery environment with half day of sun and, therefore, with some shade influence.
Key words:
guapuruvu; nursery; shade influence
