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.

Diverse practices related to livestock intensification often have a deep impact on grassland diversity. Moreover, alternative degraded states that are hardly reversible can be observed, resulting in low-diversity communities, dominated by invasive alien species. Therefore, the need arises to understand aboveground vegetation dynamics in these communities, and the potential of the seed bank to revert this degradation. In this study, we evaluated the impact of overseeding alien legumes coupled with phosphorus fertilization over natural grasslands, in terms of aboveground vegetation composition and soil seed bank. This was performed in a long-term experiment (23 years) in eastern Uruguay with three treatments: (1) native grasslands and native grasslands overseeded with alien legumes and fertilized at a (2) moderate or (3) high phosphorus dosage. Vegetation surveys were done in 2009 and 2019 to evaluate changes, and the seed bank was sampled in 2019. Native grasslands had higher total richness, native species richness and abundance for both years, as well as a higher species turnover in both temporal and spatial dimensions. The dominant species in overseeded treatments was the invasive alien grass Cynodon dactylon. The seed bank was similar between treatments in terms of seed density and richness, but differed in composition, with a higher abundance of alien species in the overseeded grassland. Seed banks showed low similarity with the aboveground vegetation. The overseeded grassland appears to be in a degraded state of low species diversity, with low turnover and invaded by alien species. The seeds in the soil appear to be insufficient to revert this condition and might be a hindrance for restoration due to the high abundance of alien species. Grasslands that have been degraded by long periods of fertilization and overseeding legumes present a great challenge for ecological restoration, since invasive alien species should be controlled before native species are reintroduced.
