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.

ABSTRACT.- 'GVU Yvyrá' is a new apple cultivar developed and released by "Grupo Viveros del Uruguay". Trees are rustic, vigorous, with good branch growth behavior, and presenting a low chill requirement. It presents early flowering, starting around September 1st, and its harvest begins before January 15th (in southern Uruguay). Large to very large fruits, with cone shape, approximately 90% red-brown blush and sweet, yellow colored flesh, and a good cold storage potential. Since most commercial apple cultivars need cross-pollination to obtain an efficient production, they are planted together with at least two cross-compatible cultivars. However, due to the 'GVU Yvyrá' early and large period of flowering, the best pollinizers for this cultivar remain unclear. The aim of this study was to evaluate different potential pollinizers for the new cultivar 'GVU Yvyrá' by controlled pollination on a commercial orchard in Uruguay. Treatments consisted of self-pollination (with and without emasculation), and controlled cross-pollination with six different early blooming cultivars. Phenology of all cultivars, and fruit set after the different treatments were evaluated. All genotypes had coincident flowering with 'GVU Yvyrá', differing in the timing of blooming stages (beginning, full and end of bloom). Whereas 'Princesa' and 'Eva' had the beginning, full and end of bloom similar to 'GVU Yvyrá', 'Anna' flowering coincided with the beginning of 'GVU Yvyrá' bloom, and 'Duquesa' flowering coincided with the end of 'GVU Yvyrá' bloom. Self-pollination rates of 'GVU Yvyrá' did not provide commercially profitable fruit set and production showing fruit set rates of 0% (for emasculated flowers) and around 5% (for non-emasculated flowers). Fruit set ranged from around 25% with 'Duquesa' pollen to around 55% of fruit set for 'Eva' pollen. Regardless the cultivars utilized as pollinizer, all the genotypes are efficient for 'GVU Yvyrá' flower fertilization and fruit set and can be used as pollinizers in a commercial orchard. © 2022 International Society for Horticultural Science.
