“…plants between B0 and B05 (Table 1) (Papadakis et al 2003;Boaretto et al 2008). Nevertheless, the root growth defects were observed and could be ascribed to the inhibition of root elongation through limiting cell enlargement and cell division in the growing zone of root tips (Cakmak and Rö mheld 1997).…”

“…However, they are not synthesized in citrus plants. In this species, sucrose is the predominate forms (Boaretto et al 2008). More recently, increasing evidence showed that nonsugar alcohol-producing plants could transport boric acid preferentially to young tissues only under B deficiency (Matoh and Ochiai 2005;Huang et al 2008), suggesting that plants are capable of sensing B level and regulating B distribution within the plant.…”

“…Taylor and Dimsey (1993) found a strong effect of rootstocks of navel citrus on B concentration in orange leaves. 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).…”

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.

“…This result was also observed for potassium (Cao et al 2012a) and manganese in C. oleifera (Cao et al 2012b). About 20 to 35% of boron content in the new parts of orange trees come from plant reserves (Boaretto et al 2008). In the field, when boron was sprayed once on the leaves, about 4% of the fruit boron was derived from the foliar fertiliser (Leite et al 2007).…”
