“…However, in contrast to the present research findings, in oak [10] and peach trees [11] substantial retranslocation of Zn during senescence was reported. Also Sanchez et al [16] found a retranslocation of foliar applied Zn before leaf fall. However, this retranslocation was with 5e7% of leaf absorbed Zn relative small.…”

“…Our understanding of the factors that determine the ultimate efficacy of foliar applications remains poor and the response of plants to foliar Zn applications is highly variable (Fernández and Brown, 2013). Many reports indicate that foliar application of Zn may significantly increase the concentrations of Zn in the applied leaves but may have little effect on foliar concentrations in non-sprayed tissues or tissue that develop subsequent to the foliar application (Zhang and Brown, 1999; Mirzapour and Khoshgoftar, 2006; Sanchez et al, 2006). The factors that control the uptake and subsequent translocation of foliar applied nutrients out of the leaf, and the effect of spray formulation on these processes are poorly understood (Bukovac, 1985; Adamec, 2013; Fernández and Brown, 2013).…”

“…The factors that control the uptake and subsequent translocation of foliar applied nutrients out of the leaf, and the effect of spray formulation on these processes are poorly understood (Bukovac, 1985; Adamec, 2013; Fernández and Brown, 2013). While various approaches have been used to determine the efficacy of foliar applied nutrients using stable and radioactive isotopic labeling (Wittwer and Teubner, 1959; Bukovac, 1985; Sah and Brown, 1998; Boaretto et al, 2001; Sanchez et al, 2006), it remains challenging to determine the pathways of mobilization from leaf to shoot and to monitor the influence of foliar formulation on phloem loading and micronutrient transport.…”

Enhancing nutrient uptake and the subsequent elemental transport from the sites of application to sites of utilization is of great importance to the science and practical field application of foliar fertilizers. The aim of this study was to investigate the mobility of various foliar applied zinc (Zn) formulations in sunflower (Helianthus annuus L.) and to evaluate the effects of the addition of an organic biostimulant on phloem loading and elemental mobility. This was achieved by application of foliar formulations to the blade of sunflower (H. annuus L.) and high-resolution elemental imaging with micro X-ray fluorescence (μ-XRF) to visualize Zn within the vascular system of the leaf petiole. Although no significant increase of total Zn in petioles was determined by inductively-coupled plasma mass-spectrometer, μ-XRF elemental imaging showed a clear enrichment of Zn in the vascular tissues within the sunflower petioles treated with foliar fertilizers containing Zn. The concentration of Zn in the vascular of sunflower petioles was increased when Zn was applied with other microelements with EDTA (commercial product Kick-Off) as compared with an equimolar concentration of ZnSO4 alone. The addition of macronutrients N, P, K (commercial product CleanStart) to the Kick-Off Zn fertilizer, further increased vascular system Zn concentrations while the addition of the microbially derived organic biostimulant “GroZyme” resulted in a remarkable enhancement of Zn concentrations in the petiole vascular system. The study provides direct visualized evidence for phloem transport of foliar applied Zn out of sites of application in plants by using μ-XRF technique, and suggests that the formulation of the foliar applied Zn and the addition of the organic biostimulant GroZyme increases the mobility of Zn following its absorption by the leaf of sunflower.

“…This may be because a decrease in the concentrations of relative immobile nutrients Cu and Fe occurred during the dry hydrological cycle 2005/2006 ( Barker and Pilbeam 2007;Correia et al 2008). On the other hand, once within peach trees Zn is quite mobile (Sanchez, Weinbaum, and Johnson 2006), and it had also greater concentrations in plant tissues in year 1 compared to year 2. The result can be probably a dilution effect because in year 2, fruit yield was relatively greater and reproductive and vegetative growth was more vigorous.…”

During the cultivation period of 2005-2007, a project was carried out in the region of Eirinoupolis, prefecture of Imathia, Macedonia, northern Greece. The study investigated the application of boron (B) timing (flowering, fruit set, fruit growth) and method (soil and foliage) on the vegetative growth, fruit yield and quality, and nutritional status of the cling-stone peach variety Andross. The cultivar was grafted onto an 8-year-old rootstock GF 677. The results showed that the greatest marketable yield (135 kg tree -1 ) was achieved in peach trees where B was applied on soil during the flowering stage in combination with a balanced nitrogen-phosphorus-potassium (NPK) basal application. Boron concentration in fruits of that treatment was increased in both cultivation years compared to most of the applied treatments. Foliar application of B at flowering, fruit set, and fruit growth, primarily in combination with foliar calcium (Ca) application, showed fruits to be less affected by cracking andMonilinia over all treatments. However, foliar application of Ca did not significantly promote leaf or fruit Ca concentration.
