ABSTRACT

The objective of this work was to evaluate the technical feasibility of budding in A. angustifolia
in two rootstocks establishment, performed in two seasons of the year. In October and April,
patch and flute budding techniques were carried on rootstocks kept indoor (greenhouse) and
established outdoor (field), with grafts of adult female plants. The percentage of survival,
percentage of shoots and number of shoots up to 300 days after budding (DAB) were evaluated.
The patch budding performed in October showed the greatest grafts survival rates (82%) and
percentage of shoots in the grafts (64%) at 180 DAB. The flute budding showed highest number
of shoots (2.7 at 120 DAB and 3.5 at 180 DAB) when compared to patch budding. The use of
the patch budding is recommended in spring, not requiring a controlled environment for the
rootstocks. After 180 DAB there were no losses of grafted plants.
