“…Titanium exerts a beneficial effect on various plant physiological processes, leading to earlier and higher crop production. Titanium applied via roots or leaves stimulates plant growth in a species-specific manner (Dumon and Ernst, 1988;Pais et al, 1991;Carvajal and Alcaraz, 1998;Du et al, 2010). According to Jabłoński (2000), a double Tytanit ® application in the dose of 0.3 dm 3 *ha -1 in the early crop potato culture (formation of basal side shoots stage -BBCH 21-23 and in the beginning of flowering -BBCH 61) can increase the marketable tuber yield by 1015%.…”

“…Although in this form it is not bioassimilable, when applied in a watersoluble, pHstable Ti-chelate organic acids form such as ascorbate, citrate or malate, it has a beneficial effect on various physiological processes, i.e. it stimulates the chlorophyll biosynthesis and the activity of many enzymes (catalase, peroxidase, lipoxygenase and nitrogen reductase) and the uptake of some nutrients for plants, as well as accelerates plant growth, increases crop yield and improves the crop quality (Dumon and Ernst, 1988;Pais et al, 1991;Carvajal and Alcaraz, 1998;Hrubý et al, 2002;Du et al, 2010).

The growing period for early potatoes is extremely short, only 50-80 days from planting to harvest. To obtain a high marketable tuber yield in such a short period good conditions for plant growth must be ensured. In modern agriculture, plant growth stimulants have been gaining increasing importance. Although titanium (Ti) is neither a major nor minor nutrient for plants, it is classified as a beneficial element for plant growth. This paper analyses the effect of dose (0.2 dm ) on the yield and yield components of very early-maturing potato cultivars ('Lord' and 'Miłek'). Potatoes were harvested 75 days after planting (the end of June). Tytanit ® caused an increase in the tuber number and tuber weight per plant, particularly under stress conditions, although the effect of cultivars was not consistent. The growth stimulant did not have any effect on the average tuber weight. Following the application of Tytanit ® , the total tuber yield was higher, on average, by 2.26 t*ha -1 (7.5%), and the marketable tuber yield (diameter above 30 mm) by 1.88 t*ha -1 (6.4%). The tuber number per plant was higher when Tytanit ® was applied at the dose of 0.2 dm 3 *ha -1 . Potato plants produced greatest tubers when Tytanit ® was only applied in the leaf development stage (BBCH 1416). With double Tytanit ® applications, i.e. in the leaf development stage and with repeated treatment in the tuber formation stage, both the tuber number and tuber weight per plant were lower. The Tytanit ® application contributed to improved marketable value of the early potato yield due to a decreased share of small tubers (diameter below 40 mm) and an increased share of large tubers (diameter above 51 mm) especially in a year with a periodical water shortage in the tuber growth period. The examined very earlymaturing potato cultivars showed a differential response to Tytanit ® . The growth stimulant had a greater effect on the tuber number and tuber weight per plant for the 'Lord' cultivar. Following the Tytanit ® application, the total tuber yield of 'Lord' cultivar was higher , on average by 3.71 t*ha -1 (12.7%) and marketable tuber yield by 3.22 t*ha -1 (11.4%). Tytanit ® caused an increase in tuber yield of 'Miłek' cultivar only in year with the highest air temperature and water shortage in June -the total tuber 441

“…Within the human body it is used for dental and orthopedic prosthetics [3, 4]. The metal, however, remains largely unappreciated for its biological importance despite many examples of its benefit to plants [5–8] and animals [9–11]. This response partly stems from the belief that Ti is nonessential to humans.…”

Despite its natural abundance and widespread use as food, paint additive, and in bone implants, no specific biological function of titanium is known in the human body. High concentrations of Ti(IV) could result in cellular toxicity, however, the absence of Ti toxicity in the blood of patients with titanium bone implants indicates the presence of one or more biological mechanisms to mitigate toxicity. Similar to Fe(III), Ti(IV) in blood binds to the iron transport protein serum transferrin (sTf)1, which gives credence to the possibility of its cellular uptake mechanism by transferrin-directed endocytosis. However, once inside the cell, how sTf bound Ti(IV) is released into the cytoplasm, utilized, or stored remain largely unknown. To explain the molecular mechanisms involved in Ti use in cells we have drawn parallels with those for Fe(III). Based on its chemical similarities with Fe(III), we compare the biological coordination chemistry of Fe(III) and Ti(IV) and hypothesize that Ti(IV) can bind to similar intracellular biomolecules. The comparable ligand affinity profiles suggest that at high Ti(IV) concentrations, Ti(IV) could compete with Fe(III) to bind to biomolecules and would inhibit Fe bioavailability. At the typical Ti concentrations in the body, Ti might exist as a labile pool of Ti(IV) in cells, similar to Fe. Ti could exhibit different types of properties that would determine its cellular functions. We predict some of these functions to mimic those of Fe in the cell and others to be specific to Ti. Bone and cellular speciation and localization studies hint toward various intracellular targets of Ti like phosphoproteins, DNA, ribonucleotide reductase, and ferritin. However, to decipher the exact mechanisms of how Ti might mediate these roles, development of innovative and more sensitive methods are required to track this difficult to trace metal in vivo.

“…The overwhelming majority of titanium is poorly available for plants, because it is present mostly in the form of minerals (as TiO 2 or FeTiO 3 ) that are insoluble in water. Titanium is classified as a beneficial element for plants, which can promote or improve the growth and development of some plant species or under specific growth conditions [Pais 1983, Dumon and Ernst 1988, Pais et al 1991, Carvajal and Alcaraz 1998]. Titanium under ordinary circumstances is not taken up by plants; however, when applied as Ti-chelate organic acids such as ascorbate, citrate and malcate, it has a beneficial effect on various physiological processes.…”

A condition for achieving a high potato tuber yield on an early harvest is to provide plants with good growth conditions. In modern horticulture, plant growth stimulants have been gaining increasing importance. This study examined the effect of dose (0.2 dm 3 ha-1 or 0.4 dm 3 ha-1) and date (leaf development stage-BBCH 14-16, tuber formation stage-BBCH 41-43, leaf development stage and tuber formation stage) of Tytanit ® application (8.5 g Ti in 1 dm 3) on the growth of very early-maturing potato cultivars ('Lord', 'Miłek'). Following the Tytanit ® application, the plants were higher and produced a greater aboveground biomass and tuber weight, however, the leaf weight ratio (LWR) and leaf area ratio (LAR) were lower than in the cultivation without the growth stimulant. Tytanit ® had a greater effect on the leaf weight ratio (LAR) and tuber weight for the 'Lord' cultivar. Tytanit ® dose had no effect on the plant growth. A double Tytanit ® application resulted in a reduction in the length and weight of stems and tuber weight. The date of Tytanit ® application had no effect on the weight of leaves. The leaf area ratio (LAR) was the highest when Tytanit ® was only applied in the tuber formation stage, and the leaf weight ratio (LWR) was the highest when Tytanit ® was applied twice. A positive correlation was found between the tuber weight and the LWR and LAR.
