“…Regarding B in roots, its correlation with the applied amount of B was linear in both limed and acidic soils (r 2 equal to 0.96 and 0.90, respectively). In line with this, similar effects of B addition on B accumulation in roots were reported for olive (Chatzissavvidis and Therios, 2010), grapevine (Yermiyahu et al, 2006) and citrus (Papadakis et al, 2004). Rootstock B concentration exhibited similar positive responses to added B, as those found for leaves and roots.…”

Two year-old apple plants (Malus domestica cv. Red Chief Delicious) were grown in an acidic and limed soil, and fertilized with B (0, 1, 3 and 5 mg kg -1 soil). Fresh matter weight of plants was positively correlated with the applied B only in acidic soil. The number of nods, plant height, stem diameter, and shoot length were not particularly affected by either B additions or liming. The length of internodes of the plants grown in limed soil showed a positive correlation with the amount of added B, but the opposite effects were observed in the acidic soil. Boron and K concentration in leaves showed a positive correlation with added B in both soils. Leaf N and Fe concentrations were negatively affected by B additions in soils, while leaf Mn and Zn concentrations were also affected by added B and soil pH, reflecting thus their soil mobility. Chlorophyll content in leaves was reduced at high B treatments, only in plants grown in the acidic soil. Our results show that added B even in our high B-content acidic soil did not cause any detrimental effects on apple plants, and that liming seemed to buffer trace metal excesses, characteristic of any acidic soil.

“…Boron availability is dependent on soil pH and Chl concentration on B, thus there was the observed link between pH and Chl. Other researchers, who studied apple plantlets and mandarin plants treated with B, also reported the same decreasing trend with added B (Mouhtaridou et al, 2004;Papadakis et al, 2004).…”

“…Abiotic stresses, such as toxicity, can promote the disorganization of the thylakoids, which negatively affects the chloroplast structures and reduces the production of photosynthetic pigments, such as CHL b (Papadakis et al, 2004;Wang et al, 2011). Decrease in the CHL b level were described by Han et al (2009) working with Citrus grandis under the stress of B in nutrient solution.…”

Glutathione, a peptide frequently associated with the antioxidant mechanism of plants against reactive oxygen species, and proline, an amino acid whose function is related to cellular homeostasis, can both contribute to improve plant tolerance under situations of abiotic stress, such as boron toxicity. Aims of this research were to (i) quantify the oxidant and antioxidant compounds, (ii) evaluate the photosynthetic pigments, (iii) determine amino acids and PRO, and (iv) determine whether GSH and PRO contribute to the tolerance mechanisms in young Schizolobium parahyba var. amazonicum plants under B toxicity. This experiment tested five boron levels (25, 50, 100, 150 and 250 µM B), being evaluated physiological and biochemical variables. The values reported to proline levels presented significant variation for treatments with 50, 100, 150 and 250 µM B, with increases for the 150 and 250 µM B levels, being 45.2 and 52.4%, respectively. This study found that boron toxicity promoted similar behaviours in both the leaves and root, which included progressive increases in hydrogen peroxide, electrolyte leakage, amino acids and proline, and decreases in total glutathione, chlorophyll a, chlorophyll b and total chlorophyll, confirming that proline but not glutathione actively participates in the tolerance mechanism of young Schizolobium parahyba plants exposed to boron toxicity.

“…Boaretto et al (2008) studied the variation of Valencia sweet orange trees budded on Rangpur lime or Swingle citrumelo in response to B and suggested B concentration in Swingle was higher than that in Rangpur. And rootstock can also greatly affect the scion's tolerance to B toxicity (Papadakis et al 2004) and deficiency (Boaretto et al 2008). In addition, interaction of scion-rootstock combination was also reported in other plants, such as melon (Edelstein et al 2005), apple (Wojcik et al 2003), olive (Chatzissavvidis et al 2008), and pear (Sotiropoulos et al 2006).…”

Boron (B) deficiency is widespread and serious in navel orange orchards in southern Jiangxi in China and has been considered an important soil constraint to citrus yield and quality. It has been observed that there was great variation in responses to different B supply levels between ''Newhall'' navel orange grafted on citrange and trifoliate orange. The aim of this work was to compare the different responses of the two scion-rootstock combinations under different B stresses (low and high) in young citrus trees. ''Newhall'' navel orange grafted on citrange or trifoliate orange were incubated in nutrient solution containing different levels of B (0, 0.5 and 5.0 mg L À1 ), of which 0 and 5.0 mg L À1 were considered as deficient and excessive B and 0.5 mg L À1 was considered as an appropriate level of B. The experiment was carried out in a greenhouse for 117 days. The results showed that, under low B or high B conditions, better growth performance was observed in ''Newhall'' plants grafted on citrange than in those grafted on trifoliate orange, suggesting that citrangegrafted plants were more tolerant to deficient and excessive B than the plants grafted on trifoliate orange. Boron seemed to be preferentially translocated to the new leaves (leaves from current year), and resulted in normal growth of young leaves under limited B supply. Boron distribution in different plant parts indicated that there was a restriction in translocation of B from roots to scion tissues (stems and leaves of scion) under limited B availability. The relatively high B concentration observed in plants grafted on trifoliate orange suggested higher demand for B than those grafted on citrange. There existed a balance within the B forms to maintain normal growth. Thus, R value (R ¼ semi-bound B/free B) was much higher in citrange-grafted plants than in trifoliate orange-grafted plants under the same B supply level. This explained why citrange-grafted plants had less B but produced relatively more dry mass at cellular level. These results suggested that the utilization efficiency of B of citrange-grafted plants was probably greater than trifoliate orange-grafted plants.
