The effect of different biostimulators on morphological and biochemical parameters of micropropagated Hosta ’Gold Drop’
Published July 29, 2019
22-29.

During in vitro multiplication of Hosta ‘Gold Drop’, 20 g l-1 sucrose, 5.5 g l-1 agar and 4 concentrations (0.1-0.8 ml l-1) of Ferbanat L, Kelpak, Pentakeep-V were added to half-strength Murashige and Skoog (MS) basal medium. As compared to the control and other biostimulators, plants with lower per...oxidase activity, larger fresh weight, more, longer shoots and roots, larger leaves were developed on medium containing Kelpak. The best concentration was 0.4 ml l-1 for in vitro rooting, shoot formation, plant weight and ex vitro chlorophyll, carotenoid level, peroxidase activity. Pentakeep was the less efficient biostimulator, increasing of its concentration mostly decreased root and shoot values (furthermore, abnormal callus formation was observed, as non-wanted effect), chlorophyll content and sizes (length, width) of leaves, not only during in vitro propagation but also (as after-effect) acclimatization because of the high mortality and weakly developed survivor plants.

The effect of Ferbanat L nano-fertilizer on the growing of Petunia x grandiflora ’Musica Blue’
Published September 7, 2014
107-109.

During our experiment, the effect of Ferbanat L concentrations were examined by Petunia x grandiflora ‘Musica Blue’ production. The leaf and shoot length, number of flower buds, diameter of flowers, and the date of appearing the first buds were measured. The solution of Ferbanat L in 0.1 % concentration was the most effective on shoot lengt...h (21.7 cm). Remarkable increase was observed by the other treatment groups as well comparing to the control group (5.6 cm), the plants treated with solution of Ferbanat L 0.2% (16.5 cm) and 0.3% (14.4 cm) had significant effect as well. The nano-fertilizer had not positive effect on the other examined parameters as leaf and flower size, number of flower buds or chlorophyll content. The culture period shortened five days.

Boistimulator effect of stress tolerant rhizobacteria on horticultural models
Published April 22, 2014
83-87.

The tolerant bacteria for abiotic stresses such salinity, drought, and different pH have been used as a good tool to improve plant growth in sustainable agriculture. A pot experiment was conducted to evaluate the potential of isolated stresstolerant bacteria for red mud-polluted soil on growth performance of giant reed plants with increasing co...ncentrations of NaCl 0.0; 0.1; 0.2; 0.3; 0.5; 1.0% under gnotobiotic conditions. At the same time biostimulator potential of isolated bacteria was observed in case of radish in vitro germination experiment under salt stress. It was found that the observed bacterial strain can tolerate the salt and pH moderately however it is resistant against hydrogen-peroxide caused oxidative stress in high concentration (up to 2640 mM). Molecular identification, basis on 16S rDNA showed 98% similarity to the Bacillus aryabhattai bacterial strain. The isolated strain alleviated the negative effect of salt (0.05%) for the radish seed germination. However in higher salt concentration (≥0.1%) the bacterial mitigating effect vanished. The inhibition of increasing salt concentration for giant reed plantlets was also alleviated by halotolerant bacteria treatment (≥0.5%).

Effect of Fertileader® Vital on green pea maturation
Published July 25, 2013
57-59.

The changes of tenderness of three green pea varieties with different maturity were studied after Fertileader® Vital fertilizer treatment. The fertilizer treatment caused signifi cant differences in the tenderness of treated plants in every year. After the second measuring time; the treated plants showed better quality than the control ones. T...he treated varieties kept their tenderness longer due to this foliar fertilizer, the yield have better quality so even better suited to the requirement of canning industry. Use of Fertileader® Vital is of an economic importance because high economic benefi t can be realized in one hectare after Fertileader® Vital treatment. By using this foliar fertilizer 12,840 HUF extra profi ts can be realized by producing green peas of I. quality class instead of yield with II. quality category. This extra profit could increase to 447,840 HUF considering that green peas belong still to the II. quality class after fertilizer treatment when the quality of non-treated plants are no more suitable for the canning industry.

Comparative study of effects of a complex fertilizer and a biostimulator on macroelement content of leaf and fruit quality on sweet cherry (Prunus avium)
Published September 19, 2007
91-94.

In this study. we are partly focusing on consumer acceptance of fruit, like fruit cracking, weight and flavours, and maturation, fruit density and content of nutrients which are undelie consumer acceptance, and important equally to the growers and marketers. the results on the dynamics of N-uptake corresponded ti thephenological phases of cherr...y and independent on the applied treatments. Younger leaves contain more N than elder due to the effective N uptake of young leaves. Based on the measurements conducted in June, the P content of leaves was in low P supply category at the control and the Benefit treatment, while was in the lower range of optimal category at Damisol treatment. According to our measurements, the K of cherry leaves decreases continuosly until September, expcept the control at which it increased from the end of June to September. the fruit weight was increased significantly by applying Benefit PZ. the best results for fruit cracing observed at Benefit treatment too. The best result for fruit density was observed at Damisol treatment.
