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.

ABSTRACT.
Pear is a temperate crop, which grows in mild winter regions, and may present several development anomalies, which can negatively affect yield and fruit quality. To overcome these obstacles and achieve economically satisfactory yields, the use of bud break promoters has shown promising results. The most used promoters are hydrogen cyanamide (HC), mineral oil (MO) and Erger®. The present study aimed to evaluate the effectiveness of HC, MO and Erger® following different chilling hour accumulation on bud break of 'Hosui' pear. 'Hosui' pear shoots were collected with 103 chill hours (CH) and conditioned in cold storage at 4±1°C for 0, 6, 12, 18, 24 and 30 days. For each date, shoots were cut as single bud cuttings, where the following treatments were applied in four replications of ten cuttings: control (water), HC 1%, MO 5%, Erger® 3% + calcium nitrate 3%, and HC 0.5% + OM 3%. After these, they were forced in a growth chamber until bud break, which was assessed every two days to estimate the bud break percentage and average bud break time. Bud break percentage showed no difference between treatments when submitted to 0 and 6 days (247 CH) of cold storage. After 12 days (391 CH), HC and HC + MO increase bud break percentage compared to the control. Those exposed to 18 days (535 CH) and treated with HC and HC + MO showed no significant difference in the bud break percentage compared to the control, whereas Erger® and MO significantly decreased the bud break percentage compared to other treatments. The average bud break time of HC treated cuttings was advanced the most and control delayed the most. When cuttings were subjected to low chilling hour accumulation, HC and HC + MO were more effective in bud break compared to Erger® and the control, while with higher chilling hour accumulation, the bud break promoters were dispensable.
