“…The influence of rootstock on the mineral composition of leaves in the scion is well known in citrus plants (Eaton and Blair 1935). In the present study, plants grafted on trifoliate orange had a higher B concentration than plants grafted on citrange (Table 2).…”

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.

Sunzinary. Studies The concept of intraspecific variation in mineral element acctnmuilation in plants has only recently been recognized in its broad scope.
