Abstract
he objective of this study was to evaluate the grafting of rubber tree seedlings produced on a suspended workbench in full sun, at three different times. One of the major problems in the production of seedlings on a suspended workbench is related to grafting (grafting time and type of bud used). In order to evaluate better times for grafting, an experiment was carried out in a seedling nursery in Mendonça, São Paulo State, Brazil, produced on a suspended workbench in full sun. The design used was randomized blocks, with three grafting times, and for each time, 15 plants were grafted, with four replications. The results were submitted to analysis of variance (ANOVA) and Tukey's test to compare means using a 5% significance level. Grafting index × grafting time was evaluated. There was a significant difference between the grafting time and the grafting index ranged from 68.3% to 95%, depending on the grafting time. It is concluded that climatic factors influence grafting index. Keywords: Graft. Hevea brasiliensis. Clime.
