Microelements play an important role in the production of horticultural plant seeds. A great attention was devoted to titanium, which according to the literature, accelerates germination of pollen grain, thereby increasing the yield of fruit and seeds as well as improves the health status and quality of seeds. The research was carried out to determine the effect of Tytanit containing 0.85% of titanium applied at different stages of onion plant development on the yield and quality of the obtained seeds. The research was conducted in 2003-2005 in the field of Research Institute of Vegetable Crops and Research Institute of Pomology and Floriculture. The experiments were designed in three randomized blocks, in three repetitions and with three onion cultivars: Sochaczewska, Supra and Błońska. Tytanit was applied before sowing (during seed soaking) or during vegetation period as a foliar spray from the beginning of flowering till the seed harvest at the concentration of 0.04% - 600 dm3 water∙ha-1. The treatments were performed at three different stages of plant development, every 7-10 days. Independently of the stage of plant development, the application of Tytanit significantly increased the yield of onion seeds of all the examined cultivars. The highest onion seed yield was obtained after spraying plants with this chemical during full flowering. Similarly, foliar application of Tytanit during full flowering of onion plants significantly improved the quality of seeds. This chemical also significantly increased the weight of 1000 seeds as well as their germination in all the examined cultivars in comparison with the control. The onion seeds obtained after the application of Tytanit during full flowering are characterized by better health status.
Foliar application of growth regulators or fertilizers containing biostimulators can influence the uptake and accumulation of mineral elements by plants. A pot experiment carried out in two annual series (year of experiment I and II) examined the effect of various concentrations of Tytanit applied once or twice against mineral fertilization (NPK), in comparison with the control object (without fertilization) and the object with mineral fertilization (NPK), on the total content of potassium, calcium, magnesium and sodium in petioles and leaf blades of celery. The experiment involved the application of various concentrations of Tytanit, ranging from 0.001% to 3.6%. The content of selected elements in the plant material was determined after dry mineralization, using the ICP – AES method. The total content of potassium in petioles of celery fertilized with NPK + 3.6% was higher or the same as in the control and in plants fertilized with NPK (I and II series). The results were similar in the case of leaf blades (except for series I). The highest concentration of Tytanit (3.6%) resulted in a reduction of the total calcium content in both of the tested parts of celery and magnesium in petioles, compared with the control. On the other hand, the total content of sodium increased along with the growth of the fertilizer concentration. The highest bioaccumulation of calcium was observed in celery cultivated in the object without fertilization (control). A significantly higher potassium content (mean from both series of research) and over two-fold higher content of calcium were found in celery leaf blades than in petioles, while a higher content of magnesium and sodium appeared in petioles than in leaf blades. The values of (K+Na) : (Ca+Mg) ratios in leaf blades were found to be over two-fold higher than in petioles of celery fertilized with Tytanit.
Doświadczenie połowę przeprowadzono na krzewach odmiany uprawnej ‘Flamingo’ w latach 2002-2004. Tytanit stosowany był w formie oprysku w czterech stężeniach 0,01; 0,02; 0,04 i 0,06%, przy dwóch częstotliwościach oprysku 4 i 8 w okresie wegetacji. Oprysk Tytanitem w stężeniach 0,01-0,04% korzystnie oddziaływał na masę krzewu, liczbę pędów II-ego rzędu oraz średnicę pędów. Zwiększona częstotliwość opryskiwania roślin w okresie wegetacji nie miała istotnego wpływu na badane cechy.
An experiment was conducted to determine the effect of Asahi SL (0.1%), Tytanit (0.04%) and their mixture (Asahi SL + Tytanit), used three times to spray strawberries, on the number of runner transplants, fruit yield, weight of one berry and extraction content in fruit. Compared with the control, only the combination of Asahi SL and Tytanit significantly increased the number of runner transplants. Asahi SL significantly increased fruit yield but, when applied in combination with Tytanit, it did not increase the effectiveness of spraying. The yield of strawberries treated with Tytanit only was similar to the control. Neither of the chemicals examined in the experiment significantly increased the weight of one berry or extraction content in fruit. Tytanit and Asahi SL displayed an anti-stress effect by increasing the weight of one berry at the first dates of fruit harvest.

The healthiness analysis of Sparaxis sp. corms was carried out in the years 2002-2003 on the experimental fields of The Agricultural University near Lublin. Plants were cultivated in trials treated with: Asahi SL (sodium nitrophenole derivates), Tytanit (tytanium), herbicides: Afalon 450 SC (linuron), Devrinol 450 SC (napropamide), Stomp 400 SC (pendimethaline) and in control trial without treatment. The healthiness was evaluated after digging and after storage. Among fungi isolated from sparaxis corms after digging and storage, the species Fusarium oxysporum predominated. The corms infected with it were deformed, wrinkled and covered with brown, scaby lesions. This species also dominated among fungi isolated from all the trials, regardless a preparation applied. The disease index values ranged within 6.0 - 9.25 after digging and within 9.25 - 15.75 after storage respectively. There was no a marked positive effect of a used preparation on the healthiness of sparaxis corms.
Celem doświadczenia polowego było zbadanie wpływu dolistnego stosowania wybranych stymulatorów wzrostu (Asahi SL, Bio-algeen S 90) oraz nawozów dolistnych (Mikrosol U Tytanit) na wielkość i jakość plonu surowca tymianku (Thymus vulgaris L.). Zastosowane stymulatory wzrostu oraz nawóz dolistny przyczyniły się do lepszego wzrostu roślin oraz zwiększyły masę nadziemną tymianku. Aplikacja preparatów dolistnych zwiększyła plony surowca o 2,2-23,5%. Spośród porównywanych preparatów najbardziej efektywne okazało się łączne stosowanie Asahi SL z Mikrosolem U oraz Tytanitu z Mikrosolem U. Zastosowane preparaty dolistne spowodowały nieznaczne obniżenie zawartości olejku w surowcu. Uzyskano wzrost plonu olejku z jednostki powierzchni (największy po zastosowaniu łącznie Asahi SL z Mikrosolem U oraz Tytanitu z Mikrosolem U).
