“…Nitrogen (N) is the most important nutrient for stone fruit trees (ROMBOLÀ et al, 2012); it is the second most exported mineral element through fruits yielded by peach trees (TAGLIAVINI et al, 2000) and the most exported one through leaves and twigs (XILOYANNIS;CELANO;NUZZO, 2006). Therefore, N fertilization is essential to peach trees, since it may interfere in aspects related to vegetative growth, productivity and fruit quality (DOLINSKI et al, 2005;FALGUERA et al, 2012;FERREIRA et al, 2018;DOLINSKI et al, 2018).…”

Nitrogen, which is considered the most important nutrient for peach trees, may interfere in both quantitative production characteristics and quality of fruits. This study aimed at evaluating the effect of the combination of doses of N fertilization and different periods of cold storage on physico-chemical and phytochemical characteristics of peaches in post-harvest. The experiment had a randomized complete block design in a 4x3 factorial scheme, i. e., four doses of fertilization (0, 60, 120 and 180 Kg N ha-1) and three periods of storage (on the harvest day, on both the 15th and the 30th storage days at 1±1ºC, each followed by a day of simulated commercialization at 20±1ºC). The following aspects were evaluated in fruits yielded by peach trees of the genotype Cascata 1067: fruit color, soluble solid content, titratable acidity, pulp firmness, mass loss, total phenolic compounds and antioxidant activity. Different periods of cold storage and doses of N fertilization were found to affect epidermis luminosity, pulp firmness and titratable acidity of fruits. Peaches may be stored at low temperatures for 15+1 days. After that, loss of fruit firmness increases. N fertilization affects neither the soluble solid content nor the epidermis color of peaches, but both parameters are influenced by storage. Values of phenolic compounds and antioxidant activity decrease when there is N increment in the soil and when longer storage is carried out. Results suggest that peach composition may be affected by cultural practices, such as N fertilization, in harvest and after storage.

“…Nutritional requirements of fruit species at full production vary strongly depending on species and adopted rootstock, increasing significantly as a function of production volume (ROMBOLÁ et al, 2012). 'Capdeboscq' is widely used as a rootstock in southern Brazil due to its high germination capacity and fast development of seedlings in nursery stage (FINARDI, 1998); it originated from the cross between cv.…”

Phosphorus is part of several organic compounds in plant metabolism such as nucleotides and phosphoproteins, in addition to participating in metabolism and energy storage. This study aimed to evaluate the response of peach trees cv. Sensação to phosphate fertilization and establish the critical level of this nutrient in soil and leaves. The experiment was conducted in the 2016 and 2017 cycles in a commercial orchard located in Morro Redondo, RS, Brazil. The experimental design was a randomized block design with four replications. Peach trees were fertilized with increasing doses of phosphorus (P) of 0, 20, 40, 60, and 80 kg ha −1 of P 2 O 5 as triple superphosphate. In the two evaluated cycles, samples of soil at a depth of 0-20 cm and leaves were collected to determine mineral contents. The data were submitted to analysis of variance by the F test (P<0.05), and when the effects were significant, regression equations were adjusted. P application increased the contents of this nutrient in the soil. Leaf P contents were not affected by fertilization, as well as productivity and yield components. Thus, the critical level of P in soil and peach leaves could not be established. In soils where P contents are classified as medium and high, there is no need to apply this nutrient.

“…Estudos envolvendo nutrição em diferentes combinações copa e porta-enxerto auxiliam na recomendação de genótipos mais adequados às condições edafoclimáticas de uma região, na recomendação racional de fertilizantes, na redução de custos e na mortalidade de plantas, melhora a qualidade dos frutos, aumenta a produtividade e permite ampliar o cultivo para diferentes tipos de solo (TSiPOURiDiS et al, 2002;ROMBOLÀ et al, 2012). A avaliação de nutrientes nas folhas das copas também identifica a eficiência dos porta-enxertos na absorção e na translocação desses nutrientes, bem como os sintomas de incompatibilidade de enxertia entre os genótipos (REiGHARD et al, 2013).…”

“…Embora tenha sido proposta a análise química de ramos dormentes (JOHNSON et al, 2006) ou de flores (ZARROUK et al, 2005), a análise foliar de nutrientes em meados do verão é a prática padronizada e utilizada no mundo todo para determinar o estado nutricional das frutíferas (JOHNSON et al, 2006). A análise foliar de nutrientes, complementada com a expectativa de produtividade, a exportação de nutrientes pela poda verde, a poda de inverno e a queda das folhas permitem a reposição racional de nutrientes às plantas (TAGLiAViNi et al, 2000;FREiRE, 2002;SBcS/cQFS, 2004;ROMBOLÀ et al, 2012).…”

“…Em frutíferas de caroço, os teores de nutrientes foliares em plantas adultas variam em função da cultivar-copa, porta-enxerto, método de propagação (mudas enxertadas ou autoenraizadas), época de amostragem, idade da folha, carga produtiva da planta, ambiente pedoclimático e técnicas culturais aplicadas (COUVILLON, 1982;KNOWLES et al, 1984;BROWN;cUMMiNS, 1989;BOYHAN et al, 1995;ZARROUK et al, 2005;LEONEL et al, 2011;ROMBOLÀ et al, 2012;REiGHARD et al, 2013). No Brasil, especialmente nos últimos 25 anos, diversos genótipos e cultivares têm sido estudados como porta-enxertos para frutíferas de caroço, em diferentes condições edafoclimáticas (cAMPO DALL 'ORTO et al, 1992;DE ROSSi et al, 2004;MAYER et al, 2006;GALARÇA et al, 2012).…”

RESUMO-Teores de nutrientes foliares indicam o estado nutricional da planta, auxiliam na recomendação de adubação e, em plantas frutíferas enxertadas, podem indicar combinações de copa/porta-enxerto incompatíveis. O objetivo do presente trabalho foi avaliar os teores de nutrientes foliares na cv. Maciel de pessegueiro, enxertada em cinco porta-enxertos ('Aldrighi', 'capdeboscq', 'Flordaguard', 'Nemaguard' e 'Okinawa'). Dois pomares experimentais, localizados no município de Pelotas-RS, foram avaliados no 2° e no 3° anos após o plantio, respectivamente, nos anos de 2012 e 2013. conclui-se que os porta-enxertos 'Aldrighi', 'Capdeboscq', 'Flordaguard', 'Nemaguard' e 'Okinawa' não influenciaram nos teores foliares de P e de Mn da cv. Maciel, em ambos os pomares e anos de avaliação; o porta-enxerto 'Nemaguard' reduz os teores foliares de Mg da cv. Maciel, sem alterar a classe de interpretação agronômica; embora os teores foliares de N, Fe, Zn e B tenham sido abaixo do normal ou insuficientes, em praticamente todas as amostras de ambos os pomares e anos de avaliação, os porta-enxertos testados não influenciaram nestas interpretações. Termos para indexação: macronutrientes, micronutrientes, análise foliar, Prunus spp., Rosaceae. LEAF NUTRIENT CONTENT OF PEACH ON FIVE ROOTSTOCKSABSTRACT -Leaf nutrient content indicate the nutritional status of the tree, assist in fertilizer recommendation and may indicate incompatible scion/rootstock combinations in budded fruit trees. The objective of this study was to evaluate leaf nutrient contents of 'Maciel' peach budded on five rootstocks ('Aldrighi', 'Capdeboscq', 'Flordaguard', 'Nemaguard' and 'Okinawa'). Two experimental orchards located in Pelotas, Brazil, were evaluated on the 2 nd and 3 rd years after planting, respectively in 2012 and 2013. We concluded that 'Aldrighi', 'Capdeboscq', 'Flordaguard', 'Nemaguard' and 'Okinawa' rootstocks did not influence P and Mn leaf content on 'Maciel' peach scion, in both orchards and years of evaluation; 'Nemaguard' rootstock reduces Mg leaf content of 'Maciel' peach scion, but does not change the class of agronomic interpretation; although N, Fe, Zn and B leaf content were below than normal or insufficient in almost all samples from both orchards and years of evaluation, these studied rootstocks did not influence leaf nutrient interpretations.
