“…Ltda) at pH water 4.5. Plants were irrigated with an adequate volume of nutrient solution according to Hoagland and Arnon (1950), prepared in deionized water (< 1 μS), containing five B concentrations 0, 3, 12, 25, and 50 mg L −1 supplied as H 3 BO 3 , based on previous experiments by Meriño-Gergichevich et al (2017). Plants were grown under the greenhouse conditions with air temperature 20-25°C, 16 h photoperiod, 70-80% relative humidity, and a photosynthetic photon flux density of 450-500 μmol photons m −2 s −1 .…”

“…Recent studies indicate that the nutrient status of fruit crops may depend on B supply, the genotypic constitution, planting age, and the sampling moment during the season (Strik and Vance 2015;Wang et al 2015;Meriño-Gergichevich et al 2016). Previously, Meriño-Gergichevich et al (2017) reported changes in macronutrient composition and increased radical scavenging activity (RSA) in the leaves and roots of highbush blueberry plants grown under excessive B concentration (> 400 μM). However, there is not enough information about the composition of phenolic compounds and antioxidative capacity in highbush blueberry plants in response to increasing B exposure.…”

Highbush blueberry (Vaccinium corymbosum L.) is beneficial for human health due to its bioactive properties. Agronomic management includes boron (B) addition to promote its growth and development. We aimed to provide new insights into the effects of B supply on the phenolic profile and antioxidative capacity in the leaves of two common cultivars, Brigitta and Legacy. Seedlings of Brigitta and Legacy were supplied with different B concentrations (0-50 mg B L −1). After 30 days, leaf biomass and B content, the activity of phenylalanine-ammonia-lyase (PAL, EC 4.3.1.24), the phenolic profile, and radical scavenging activity of methanolic extracts (oxygen radical absorbance capacity (ORAC), reducing 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing-antioxidant power (FRAP)) were analyzed. Tolerance to B was assessed by the lipid peroxidation level and superoxide dismutase (SOD, EC 1.15.1.1) activity. Leaf biomass in cultivars increased at 3 mg B L −1 , while Legacy was more sensitive to higher B treatments than Brigitta, which was evidenced by increased lipid peroxidation and decreased SOD activity. Boroninduced inhibition of PAL activity was higher in Legacy. Cultivar-specific differences observed in hydroxycinnamic, flavonoid, and anthocyanin profiles of leaf extracts were related to radical scavenging capacities. The results indicate different B requirements in the two blueberry genotypes, which should be considered before B application to obtain an optimal antioxidant composition. Boron supply increased the accumulation of flavonoids in Brigitta and hydroxycinnamates in Legacy. Higher tolerance to excess B in Brigitta may be related to higher antioxidative capacity and SOD activity than Legacy.

“…In a general way, edaphic concentrations of B in the soil solution ranging from 5 to 100 mg L −1 are toxic for many species, though a large degree of tolerance can be observed among species (Maas 1990;Ferreyra et al 1997) and even genotypes (Papadakis et al 2003;Papadakis et al 2004;Cervilla et al 2007;Landi et al 2013aLandi et al , 2013b Electronic supplementary material The online version of this article (https://doi.org/10.1007/s42729-019-00054-7) contains supplementary material, which is available to authorized users.

Boron (B) is an essential micronutrient for plant growth and development, but in soil of arid and semiarid environments, B frequently exceeds the plant requirements. B toxicity hampers plant performances and productivity even though there is a lack of information about changes in leaf sugar metabolism and nutrient partitioning provoked by B excess, especially in tree sugar alcohol-producing species where B is highly mobile. In current experiment, hydroponically grown loquat seedlings were subjected to increasing B levels (25, 50, 100, 200, and 400 μΜ) in the nutrient solution for 69 days. B excess caused visible symptoms in the upper part of loquat shoots (leaves and stem), typical symptoms usually found in species where B is highly phloem mobile. Furthermore, Β excess caused significant (i) reduction of plant growth, leaf number, and stem diameter; and (ii) alterations in macro-and micronutrient allocation patterns in different plant organs, e.g., decrease of K, P, Mn, and Mg concentration in roots. Younger fully expanded leaves of B-treated seedlings showed a decline of sucrose paralleled by increments of glucose and fructose concentration in leaves, alteration of leaf pigment composition, and increased peroxidation of lipid bilayers (higher malondialdehyde by-products). Our observations suggest that loquat is very sensitive to B excess and B toxicity can affect dramatically the plant physiology and biochemistry, thus leading to changes in sugar patterns, a reduced growth and, eventually, a reduced productivity of this species.

“…Despite the plants from T3 having a low nutrient content in the shoots, there were no visual symptoms of leaf deficiency. It is possible that 'hidden hunger' was present with this treatment, characterised when plants are deficient in a specific nutrient without presenting visible symptoms, the deficiency being detrimental to plant growth (Meriño-Gergichevich et al, 2017). This was evidenced by the smaller growth of the 'Okinawa Roxo' plants in T3 when compared to T1 (Ns1) and T2 (Ns2).…”

The aim of this study was to evaluate the efficiency of nutrient uptake, accumulation, distribution and use, and its relationship with growth variables, chlorophyll content, and root and shoot dry-weight partitioning in the ‘Okinawa Roxo’ peach rootstock, submitted to different nutrient solutions and substrates. The experimental design was completely randomised, with four treatments and five replications. The treatments were T1: Ns1 = Souza et al. nutrient solution (2011), applied to a sand substrate; T2: Ns2 = Hoagland and Arnon (1950), applied to a sand substrate; T3: Commercial Substrate + H2O; and T4: Control, Sand + H2O. Ninety days after transplanting (DAT), morphological, physiological and nutritional parameters were determined in the ‘Okinawa Roxo’ rootstock, together with the correlation between nitrogen concentration and nitrogen balance index, and the chlorophyll content and index. The greatest zinc content was detected in the shoots of the ‘Okinawa Roxo’ plants, at more than 80% of the accumulated total. Treatments T1 and T2 (nutrient solutions Ns1 and Ns2 respectively) made it possible to obtain ‘Okinawa Roxo’ plants with the best morphophysiological characteristics, being ready for grafting three months after transplanting in a greenhouse. The use of the Ns1 nutrient solution resulted in greater efficiency in the uptake and use of the nutrients nitrogen (N), potassium (K) and iron (Fe). The N and Total Chlorophyll concentrations in the leaves of the red-leaved peach tree can be estimated indirectly with a chlorophyll meter, and are an accurate indication of the nutritional status of the plant in relation to nitrogen content.
