Propaga？？o de abacateiro via estacas estioladas

this research aimed to test a method of avocado propagation from etiolated cuttings in recipients with different heights. the experiment was carried out in an intermittent mist chamber. the experimental design was in randomized blocks with a 3x4 factorial and three replicates. two methods of sap obstruction (girdling or strangulation) and four heights of containers (10, 15, 20 or 25 cm) were tested. after 250 days, there was no effect of container heights on the survival, the number of developed leaves, plant height and diameter of the seedlings formed from etiolated cuttings. there was a higher survival rate and number of leaves in girdled cuttings as compared to control plants; cuttings obtained from the strangulation treatment had intermediate behavior. the previous bark girdling or strangulation of etiolated avocado branches increased survival and plant growth for the propagation of selection viam？o cuttings.
