“…In most studies, phenolic production decreases at high nitrogen availability and increases under nitrogen deficiency. 30 This trend was not followed by M. cauliflora, which showed no correlation in total phenol/ tannin contents with nitrogen levels; this phenomenon has also been reported for tannins in Colophospermum mopane (J. Kirk ex Benth.) J. Léonard (Fabaceae).…”

O conteúdo foliar de fenóis totais e de taninos, bem como a composição química dos óleos essenciais em populações de Myrciaria cauliflora cultivadas em seis diferentes sítios de amostragem indicou a presença de quatro grupos de amostras de acordo com as características químicas da folha e do solo de cultivo. O grupo I incluiu as amostras oriundas do solo franco-arenoso (S1), caracterizado pela maior e menor percentagem de g-eudesmol (11,55%) e germacreno D (20,48%), respectivamente, e alto conteúdo de fenóis totais (136,68 mg g -1 ) e taninos (60,72 mg g -1 ). O grupo II, rico em elemol (4,61%), incluiu as amostras cultivadas nos solos franco-arenoso-argilosos (S2, S3 e S6), enquanto que as amostras dos solos argilosos S4 (grupo III) e S5 (grupo IV) apresentaram as mais elevadas percentagens de germacreno D (III: 27,20%; IV: 26,83%) e os mais baixos teores de elemol (2,12-2,55%), fenóis totais (79,69 e 111,77 mg g -1 ) e taninos (34,04 e 44,51 mg g -1 ). A análise de redundância canônica revelou como o balanço de nutrientes do solo e das folhas influenciou a distribuição dos constituintes químicos nos diferentes agrupamentos. A variação química parece ser determinada por fatores ambientais.Foliar contents of total phenols and tannins and the essential oil composition of Myrciaria cauliflora populations cultivated in six sampling sites have shown the presence of four clusters related to soil types and foliar nutrients. Cluster I included samples which originated from sandy loam soil (S1) with the highest and lowest percentages of g-eudesmol (11.55%) and germacrene D (20.48%), respectively, as well as high total phenol (136.68 mg g -1 ) and tannin (60.72 mg g -1 ) contents. Cluster II, rich in elemol (4.61%), included all the samples cultivated from clay sand loam soils (S2, S3, and S6), whereas clay soils S4 (cluster III) and S5 (cluster IV) had the highest amounts of germacrene D (III: 27.20%; IV: 26.83%) and the lowest levels of elemol (2.12-2.55%), total phenols (79.69 and 111.77 mg g -1 ), and tannins (34.04 and 44.51 mg g -1 ). The canonical redundancy analysis revealed the relationship between chemical balances in the soil and leaf nutrients in different clusters. Chemovariations may be environmentally determined.Keywords: Myrciaria cauliflora, essential oil, phenol, chemical variability, environmental influence, multivariate analysis Introduction Jaboticaba, also known as guaperu or sabara, is a small native Brazilian fruit of the cauliflorus Myrtle (Myrtaceae). It is grape-like in appearance and texture, although its skin is thicker and tougher, and its color varies from grown to deep purple or black due to high anthocyanin content. 1 The ripened berries are highly perishable -postharvest decay occurs within 2-3 days -which is a problem for both transport and storage. 2 The plant is distributed in southern and central Brazilian regions and consists of about nine species of trees and shrubs, among which Myrciaria cauliflora (Mart.) O. Berg. and M. jaboticaba (Vell.) O. Berg. are the most widely cultivated ...

“…Owuor et al (1987) reported that the quality of black tea deteriorated with increased nitrogenous fertilizer ranging from 450 to 600 kg ha -1 N. The polyphenol derivatives such as theaflavins and thearubigins also decreased with increased N levels (Owuor & Odhiambo, 1994). Soil-applied N delayed the onset of tannin production, while foliar-applied urea at the time of tannin accumulation inhibited the process of tannin biosynthesis (Haukioja et al, 1998). In contrast, the results of this study showed that condensed tannins significantly decreased with higher rates of N application from 300 to 500 kg ha -1 N, probably due to a trade-off between the synthesis of phenolics and proteins.…”

“…The protein competition model (Jones and Hartley 1999) also suggests that the regulation of protein and phenolic synthesis are tightly linked due to the use of the same precursor phenylalanine. Therefore, plant cells do not appear to be capable of simultaneously synthesising proteins and phenolics at the same rate (Haukioja et al 1998). …”

(1) Increased atmospheric nitrogen deposition has shifted plant dominance from ericaceous plants to grass species. To elucidate the reduced competitiveness of heather, we tested the hypothesis that additions of nitrogen reduce the concentrations of phenolics and condensed tannins in ericaceous leaves and retard mycorrhizal colonisation in ericaceous plants. We also tested the negative effects of reduced light intensity on carbon-based secondary compounds and mycorrhizal colonisation in ericaceous plants. (2) We performed a field inventory at three heathland sites in the Netherlands varying in nutrient supply and light intensity. Leaves of ericaceous plants and grasses were collected and analysed for concentrations of tannins, phenolics and nutrients. Similarly, we took root samples to record mycorrhizal colonisation and soil samples to measure the soil mineralisation. In addition, we conducted two-factorial experiments with Calluna vulgaris plants, in which we varied fertiliser and shade levels under greenhouse and field conditions. (3) The field inventory revealed that nitrogen addition and shading both negatively affected the concentration of total phenolics. The total phenolics and condensed tannin concentrations were positively correlated (P \ 0.001), but in the field experiment, the condensed tannins were not significantly affected by the treatments. Our results provide the first evidence that the carbon nutrient balance can be used to predict the amount of total phenolics in the dwarf shrub C. vulgaris. (4) In the field experiments, shading of plants resulted in significantly less mycorrhizal colonisation. Only in the greenhouse experiment did addition of nitrogen negatively affect mycorrhizal colonisation. (5) Our results imply that increased atmospheric nitrogen deposition can depress the tannin concentrations in ericaceous plants and the mycorrhizal colonisation in roots, thereby reducing the plants' competitiveness with respect to grasses. Additionally, if ericaceous plants are shaded by grasses that have become dominant due to increased nitrogen supply, these effects will be intensified and competitive replacement will be accelerated.
