ABSTRACT.
Plants were propagated by fruits and cuttings. Cuttings were rooted in two seasons: autumn (May 19, 1992), in a field nursery under plastic cover, and spring (September 14, 1992) in plastic containers under shade. Seeds were sown in a field nursery under plastic cover on June 8, 1992. Plants were taken to the field on November 25, 1992, planted at a spacing of 30 x 40 cm. For the three treatments, the mortality of plants after transplanting was 42, 4 and 46% respectively. Within each treatment, plants were harvested on February 5, 1993, November 12, 1993 and November 3, 1994. Dry matter yield was measured for plants propagated by cuttings in autumn, for plants propagated by cuttings in spring and for plants propagated by seed. The results were 154 g/plant, 235 g/plant and 215 g/plant respectively. If compared to plants obtained by the same methods, but which were only harvested on one occasion (December 23, 1993), dry matter yields were respectively 174, 199 and 251 g/plant. These results were not subject to statistical analysis. |

ABSTRACT.
Flower induction and differentiation are complex phenomena not fully understood in pear trees. Ethylene is a plant hormone that seems to play an important role in flower induction. Exogenous ethephon (Eth) and naphthaleneacetic acid (NAA) applications have shown promising results to increase return bloom and yields in some pear cultivars. The objective of this study was to evaluate the effect of Eth and NAA on return bloom, yield and shoot length of 'Rocha' pear trees in southern Brazil. The study was performed during 2015/2016 and 2016/2017 growing seasons, using a five-year-old 'Rocha' pear orchard grafted on 'BA29' quince rootstock. Treatments consisted of untreated control, Eth 100 mg L‑1; NAA 5 mg L‑1; NAA 7.5 mg L‑1; NAA 10 mg L‑1; Eth 100 mg L‑1 + NAA 5 mg L‑1; Eth 200 mg L‑1 + NAA 7.5 mg L‑1; Eth 300 mg L‑1 + NAA 10 mg L‑1 applied at 40 + 60 + 80 days after full bloom (DAFB); Eth 150 mg L‑1 + NAA 7.5 mg L‑1 applied at 60 + 70 + 80 + 90 DAFB; and Eth 150 mg L‑1 + NAA 7.5 mg L‑1 sprayed at 40 + 60 + 80 + 100 DAFB. Shoot length in the year of application, return bloom, number of fruits tree‑1, yield (kg tree‑1 and Mg ha‑1) and average fruit weight the following season were assessed. Return bloom and yield were increased when trees were sprayed with Eth 100 mg L‑1 at 40 + 60 + 80 DAFB and Eth 150 mg L‑1 + NAA 7.5 mg L‑1 at 40 + 60 + 80 + 100 DAFB. NAA sprayed alone did not increase return bloom and yield. These results suggest that only ethephon was effective to increase return bloom, since NAA alone had no effect. Shoot length was reduced by all treatments compared to the untreated trees.
