Abstract:
'Williams' is the most cultivated pear in Uruguay and requires more than 900 chill hours to exit from the endodormancy. When this condition is not satisfied, the application of budbreak promoters is necessary to facilitate the bud swelling. The experiments were carried out in a pear orchard of 'Williams' (Pyrus communis L.) located in the Experimental Station INIA Las Brujas, during the 2017-2018 season. The objective of the study was to evaluate the effect of budbreak promoter applications on budbreak. Two experiments were performed: Experiment 1 consisted in the application of Erger® 4%, Erger® 2% and mineral oil 4%, in two dates: August 15, 2017 and September 1, 2017. Experiment 2 consisted in the application of Erger® 8% and hydrogen cyanamide 1% on August 15, 2017 and Erger® 4% on September 28, 2017. In 2017 chill units in Uruguay were 187, while the average for the last 20 years is 843. Thus chill requirements of 'Williams' pears were not met. Because of the inadequate chill accumulation (32% of the chill units NDASH CU or 78% of the total chill portions NDASH CP), no difference was observed in the final budbreak among the treatments, and the budbreak percentage never exceeded 20% for any treatment. Analyzing the budbreak discriminated per type of shoot (vegetative spurs, reproductive spurs and one-year shoots), no significant differences were observed among the treatments except for vegetative buds in experiment 1, where the treatments with mineral oil achieved a higher final budbreak (20%).

ABSTRACT.- Feathering in apple nursery trees is a critical operation used to increase the quality of planting material. Plant growth regulators (PGR) could be used to form feathers in apple nursery trees. The main goal was to study the impact of different PGR and concentrations on feathering promotion in different nursery apple trees. The study had three different trials where the specific aims were to study the impact of: i) different rates of 6-benzyladenine (6-BA); ii) different PGR (6-BA and 6-BA + GA4+7) on feathering promotion, and; iii) 6-BA on feathering promotion and prohexadione calcium (P-Ca) on trunk thickening under greenhouse conditions. Both 6-BA and 6-BA + GA4+7 were effective inducing feathering in the different cultivars tested. 6-BA reduced final young plants grafted height only in one out of three seasons, reducing an average of 15 and 10 cm on 'Early Red One' and 'Fuji' apple nursery trees, respectively. P-Ca reduced tree growth rate 4-5 weeks after sprayed, but the difference did not persist until the end of the season. Trunk diameter was not affected by the different plant growth regulators and concentrations tested. 6-BA alone or in combination with GA4+7 is an efficient tool to feathering formation in different nursery apple cultivars and conditions. © 2023, Sociedade Brasileira de Fruticultura.

Os reguladores vegetais podem ser utilizados para a formação de ramos laterais em mudas de macieira. A 6-benziladenina (6-BA), aplicada isoladamente ou combinada com giberelinas 4 + 7 (6-BA + GA4+7), é o PGR mais frequentemente utilizados para aumentar a formação de ramos laterais em mudas. O objetivo principal do estudo foi estudar o impacto dos reguladores vegetais e concentrações na ramificação lateral de diferentes mudas prode macieira. O estudo contou com três diferentes experimentos cujos objetivosespecíficos foram estudar o impacto de: i) diferentes concentrações de 6-BA; ii)diferentes reguladores vegetais (6-BA e 6-BA + GA4+7) na promoção de ramificação lateral, e iii) 6-BA na promoção de ramificação lateral e da prohexadiona cálcica (P-Ca) no diâmetro de troncoem ambiente protegido. Tanto a 6-BA quanto a combinação de 6-BA + GA4+7 foram eficazes naindução de ramos laterais em mudas, nas diferentes cultivares de macieira testadas. A6-BA reduziu a altura final das mudas apenas em um dos três anos, reduzindo em média de 15 a 10 cm a altura de mudas de macieiras 'Early Red One' e 'Fuji', respectivamente. A P-Careduziu a taxa de crescimento das plantas 4-5 semanas após a pulverização, mas a diferença não persistiu até ao final da estação de crescimento. O diâmetro do tronco não foi afetadopelos diferentes reguladores vegetais e pelas concentrações testadas. A 6-BA sozinha ou emcombinação com a GA4+7 é uma ferramenta eficiente para a indução de ramos laterais emdiferentes cultivares de macieiras e condições.
