【 摘 要 】

To reduce costs associated to ex vitro adaptation of arrow cane (Gynerium sagitatum Aubl.) plants Cv “Criolla”, the effect of three substrate mixes (Peat, peat + river sand and peat + rice husk) on survival, plant height and substrate associated plant cost were evaluated. Plants were micropropagated in semisolid MS medium supplied with 0,5 mg L-1 BAP. After medium removal, plants were transferred on 72-plug plastic trays filled with the respective substrate treatment. Trays were covered with translucent plastic covers during three days. Thereafter, plants were maintained in a 50% light shade house, fog irrigated twice a day for 1 minute each during 8 weeks. Treatments were distributed with a block randomized design. Data were analyzed with ANOVA and means were separated with Tukey´s mean separation test. Results allowed to evidence that peat + sand resulted in significant increase in survival, plant height and >35 decrease in substrate associated plant cost during adaptation to ex vitro conditions.
