The spraying with titanium is one of the agronomic practices used to stimulate the flowering, bearing of fruit and production of strawberry plants. The aim of the study was to assess the influence of titanium treatment (Ti4+-ascorbate) on L-ascorbic acid, total polyphenol, antioxidant activity, and phenolics profile of six strawberry fruit cultivars. The experiment was carried out on a commercial plantation where basic fertilization and protection of plants followed the recommendations for the species. The chemical composition of strawberries, as a response to titanium treatment, was differential and cultivardependent. A significant increase of total polyphenol content was noted only in ‘Elkat’ berries. The treatment resulted in the increase of L-ascorbic acid in all the cultivars, except for ‘Kent’. However, the influence of Ti on the antioxidant activity of strawberries against ABTS (2,2’-azinobis-(3-ethylbenzothiazoline-6sulfonic acid) and DPPH (2-diphenyl- 1-picrylhydrazyl) radical was differential. Only in treated ‘Elsanta’ fruit a significant enhancement of scavenging both radicals was observed. Moreover, the treatment caused a significant increase of total anthocyanin content in ‘Kent’, ‘Selva’ and ‘Senga’ fruit, and a significant decrease of these compounds in ‘Dukat’ berries. Regarding total proanthocyanidins, the only significant change was a decline observed in treated ‘Elsanta’ berries. The applied treatment exerted no considerable effect on ellagic acid and p-coumaric acid content in any of cultivars tested

This study evaluated the development of above and under ground parts of strawberry plants cvs. 'Fern' and 'Camarosa1 in a glasshouse using perlite, forest soil, finpeat, peat, finpeat+perlite (1:1) and peat+perlite (1:1) as substrates. The effects of different growing media on development of above and under ground parts of plant were statistically significant. The highest number of primary roots per plant, length of the most developed roots and number of crowns per runner were obtained from perlite, finpeat+perlite and peat medium, respectively, in both cultivars. The runner length, number of runners per plant, leaf area, fresh root weight and dry root weight varied between cultivars according to growth medium. In general peat, finpeat or finpeat+perlite gave the best results in terms of above and under ground parts of plants in both cultivars. Some important properties such as water retention capacity, cation exchangeable capacity, pH, porosity etc. of growing media using in this study were also determined.

The influence of the addition of Potassium Ekosorb to black soil and sandy soil on water content in soils, gas exchange in leaves and yielding of strawberry plants cultivar Senga Sengana, Dukat, Kent and Elsanta was estimated in a field experiment. The obtained results show that the addition of hydrogel increased content of water in both types of soil; however, the effect was on average twice higher in black soil than in sandy soil. The highest stomatal conductance of leaves, photosynthesis and transpiration were observed in plants cultivated in both black and sandy soil with the addition of 3 g dm⁻³ of hydrogel. The addition of higher dose influenced in an ambiguous way on the values of analyzed features of leaves. Yet, regardless of the applied dose of Ekosorb, the stomatal conductance, transpiration and photosynthesis of plants cultivated in black soil were 1.8–2.9 times higher than in sandy soil. The highest yields of fruit on both types of soil were obtained from plants which took advantage of presence of 3 g dm⁻³ of hydrogel. The application of 6 g dm⁻³ influenced on decreasing of plant yields. The weakest reaction on both types of soil occurred in strawberry cultivar Elsanta.

In intensive fruit production, in order to obtain high yields, it is necessary to use high fertilization rates as well as plant protection products. An alternative to that kind of production is presented by natural stimulators of plant growth and development called biofertilizers, biopreparations, biostimulators or phytostimulators. They are preparations of natural (plant or animal) origin, harmless to humans and the environment. Biostimulators contain biologically active substances, i.e. plant hormones, enzymes, macro- and microelements, and other compounds that stimulate the growth and development of plants. New approaches to agriculture tend to use environmentally friendly and safe products with a broad spectrum of activity. Nowadays many preparations offered for crop production are designed not only to fertilize the plants and stimulate their growth, but also to protect them from diseases or pests. Phosphite-containing products act as fertilizers or fungicides, and sometimes as biostimulants. "Resistim" is an activating stimulant and fertilizer composed of a potassium phosphite and natural betaines. Vol. 18(1)2010: 111-124 The aim of the study was to evaluate the influence of "Resistim" on the growth and development of three strawberry cultivars (Fragaria x ananassa Duch.). Two of them are short-day cultivars: 'Honeoye' and 'Elsanta', while 'Selva' is a day-neutral cultivar. The experiment was established in October 2008 under controlled conditions in a glasshouse and was carried out for three months. The plants were planted into a mixture of sandy mineral soil and peat in rhizoboxes enabling visualization of root growth and development. The plants were fertilized with standard NPK fertilization (N - 1.02 g, P - 1.9 g, K - 0.78 g per rhizobox), "Resistim" at the dose of 0.2% and 0.4% and NPK (N - 1.02 g, P - 1.9 g, K - 0.78 g) with "Resistim" at the dose of 0.2% and 0.4%, andwatered by an automatic, computer-controlled watering system. Control plants were not fertilized. The data obtained showed significant differences in the responses of the cultivars to "Resistim" treatment 'Honeoye' was the most responsive, although the other two cultivars also responded positively to the treatment with "Resistim". Further field research is required to determine whether the supplemental application of "Resistim" can be beneficial for strawberry fruit production.

Pollen viability of 11 strawberry cultivars differing of photoperiodic sensitivity was investigated. During whole flowering period, average content of fertile pollen of everbearing fruit cultivars (‘Ostara’, ‘Geneva’, ‘Mara des Bois’, ‘Rapella’) amounted 28.5% and remained at the same level, whereas day-neutral cultivars (‘Selva’, ‘Tango’, ‘Evita’, ‘Irvine’) in third decade of June and July decreased at 35.2% in comparison to May level. Radiolographic analysis of plump seeds of 5 strawberry cultivars confirmed close relationship between pollen fertility and the plump of seeds.

The study involved three strawberry cultivars: 'Senga Sengana', 'Kent' and 'El- santa', planted in the spring of 2003 in a row system in the Pomological Orchard of RIPF in Skierniewice, Poland. The experiment was carried out in 2006 on 4-year-old plants as a continuation of the project Cost 631. The strawberry plants were mulched with a peat substrate, or sawdust, or pine bark, or compost or rye straw, and inoculated with a mycorrhizal preparation Mycosat. The mulches were replenished every year in the same amount during the flowering of the plants. The results of the experiments indicate that the combinations used did not, in general, cause a significant change in the yielding of plants during the experimental period presented. An exception were the plants of the cultivar 'Kent' mulched with straw, which produced a significantly lower yield, by 18.4% on average, in comparison with the control plants or those mulched with bark. Plants of the cultivar 'Elsanta' mulched with compost or sawdust were characterized by a significantly greater mean fruit weight (by an average of 1.5 g) compared with the control. On the whole, the use of the mulches and the mycorrhizal product contributed to an increase in the number of fruits of the class 'Ekstra'. Significant differences were found on the plots of 'Senga Sengana' mulched with straw or inoculated with the mycorrhizal substrate, from which, on the average, 71% more class 'Ekstra' berries were collected than from the control plants (non- mulched). The experiments confirmed the cultivar-specific differences in yield between the strawberry cultivars studied. At comparable yields, they differed significantly in terms of the number and mean weight of the fruits collected.
