“…A better efficiency in B nutrition for a given species may be due to one or more mechanisms, such as: (1) ability to acquire B from the soil or growth medium; (2) the pattern of internal redistribution after B uptake; and (3) distinct B utilization efficiency (Rerkasem & Jamjod, 1997). Differences in B nutritional efficiency have been frequently reported among species and genotypes of the same species (Bellaloui & Brown, 1998;Subedi et al, 1999;Stangoulis et al, 2000Stangoulis et al, , 2001.…”

SUMMARYUnderstanding the magnitude of B mobility in eucalyptus may help to select clones that are more efficient for B use and to design new practices of B fertilization. This study consisted of five experiments with three eucalyptus clones (129, 57 and 58) where the response to and mobility of B were evaluated. Results indicated that clone 129 was less sensitive to B deficiency than clones 68 and 57, apparently due to its ability to translocate B previously absorbed via root systems to younger tissues when B in solution became limiting. Translocation also occurred when B was applied as boric acid only once to a single mature leaf, resulting in higher B concentration in roots, stems and younger leaves. The growth of B-deficient plants was also recovere by a single foliar application of B to a mature leaf. This mobility was greater, when foliar-applied B was supplied in complexed (boric acid + manitol) than in non-complexed form (boric acid alone). When the root system of clone 129 was split in two solution compartments, B supplied to one root compartment was translocated to the shoot and back to the roots in the other compartment, improving the B status and growth. Thus, it appears that B is relatively mobile in eucalyptus, especially in clone 129, and its higher mobility could be due to the presence of an organic compound such as manitol, able to complex B.Index terms: micronutrient, forest nutrition, translocation, polyol.(

“…Boron efficiency has been reported to be qualitatively inherited and under the control of a single gene for a number of species including celery, tomato, and red beet [11][12][13] . Jamjod et al 29 reported that both additive and dominant gene effects were involved in controlling B efficiency in bread wheat but more complicated genetics of B efficiency than a single gene was suggested for wheat 30 .…”

“…Different selection criteria may identify different mechanisms. In case of B efficiency, the extent of variation for each genotype or plant species was considered with respect to the physiological nature of the efficiency mechanisms, the genetic basis of inheritance, screening techniques and the practical implications of the genotypic variations 30 . Mechanisms for B efficiency differ with the genotypes being compared and with the intensity of deficiency.…”

Genotypic variation for response to boron (B) deficiency in wheat (Triticum aestivum L.) was determined as grain set index (GSI, %) and found to be controlled by two major genes, Bo d 1 and Bo d 2. Breeding for B efficiency may be enhanced by molecular markers associated with quantitative trait loci (QTL) for B efficiency. Two mapping populations, (Bonza × SW 41) BC2 and Fang 60 × Bonza, were made from Bonza (B inefficient), SW 41 (B moderately inefficient), and Fang 60 (B efficient) parents. Leaf samples from F2 plants from each cross were used for DNA analysis. GSI was measured in F2-derived F3 families. Seven hundred and eighty-seven simple sequence repeat (SSR) markers were used. Bulked segregant analysis and QTL analysis were performed to identify the chromosomal location for B efficiency. One QTL for B efficiency was identified and mapped in (Bonza × SW 41) BC2F3, and was found to be flanked by two SSR markers, gwm192, and gwm165. This QTL is located on the long arm of chromosome 4D between gwm165 and gwm192. This QTL region corresponded for 21% of the variation in GSI, suggesting that the chromosome segment of SW 41 parent containing the Bo d 2 locus was inherited by the progenies and that is located on 4D. Additional markers and further examination are required to locate Bo d 1, the other B efficient gene. Linked markers will enable applications of marker-assisted selection for B-efficient genotypes in wheat.

“…The different performance to B indicates the difference of B efficiency of ''Newhall'' navel orange plants grafted on the two rootstocks. A wide range of genotypic variations in B efficiency has been found in numerous species of crops and other domesticated plants (Rerkasem and Jamjod 1997). Variation in B efficiency in plant species and genotypes may be due to their different mechanisms and ability to acquire B from the soil and to distribute and utilize B in the plant (Marschner 1995).…”

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.
