Abstract

The present work aimed to evaluate the survival and the vegetative vigor of adult selected genetic material of Ilex paraguariensis A.St.- Hil. grafted directly in the field. The grafting was accomplished in approximately 3 year-old understocks, and the material collected was close to the base of two selected trees with around 70 years old. The grafting method used was the top cleft, in which 48 plants were grafted with material of each one of the two plus trees. The survival data were obtained at 60 and 90 days after the grafting, and of growth (amount and total length of sprouts) at 90 and 120 days after the grafting. It could be concluded that: there was a decrease in the survival of the grafts in function of the number of days after the grafting; the used plus trees presented different behaviors in the survival percentage; the surviving grafts plants demonstrated a good growth vigor. It is presupposed that the low percentile of success (about of 40%) is linked to the high physiologic age of the plus trees, besides less favorable environmental conditions when compared with the grafting in the nursery.
