This study evaluates the effects of different selenium levels (VI) in the form of sodium selenate (25, 50, 150 and 300 mg.dm–3) on the selected parametres in seedlings of garden pea (Pisum sativumL.) varieties (‘Flavora‘, ‘Oskar‘, ‘Exzellenz’ and ‘Jumbo‘) grown in Petri dishes. Tested indicators included seed germination, roots length, content of photosynthetic pigments – chlorophyll a and b, green biomass weight in early growth stages and acute toxicity expressed as IC50value. The study has proved a significant positive effect of selenium. During the germination, selenium doses reached 25 mg.dm–3in ‘Exzellenz’ (100 %) and ‘Flavora’ (95 %) varieties; and 50 mg.dm–3in ‘Oskar’ (the germination began 54 hours after sowing) and ‘Exzellenz’ (the germination began 48 hours after sowing) compared with a control sample. Regarding the root growth, ‘Oskar’ variety may be considered as the most resistant variety considering the value of acute phytotoxicity determined by probit analysis (1274.1 mg.dm–3). Statistically significant effect of selenium on photosynthetic pigments content has been recorded in ‘Jumbo’ and ‘Oskar’ varieties (chlorophyll a with IC50values of 1808 and 2440.1 mg.dm–3). Selenium showed a statistically significant negative effect on biomass weight and the lowest doses of acute phytotoxicity were recorded (29.9 – 42.5 mg.dm–3). The results of acute phytotoxicity confirmed that utilized levels of selenate between 50 and 100 mg.dm–3of garden pea plants are the safest for foliar application.

Experimental Field

Pea (<em>Pisum sativum</em> L.) is the second most important grain legume crop in the world which has a wide array of uses for human food and fodder. One of the major factors that determines the use of field pea is the yield potential of cultivars. Presently, pre-sowing inoculation of pea seeds and foliar application of microelement fertilizers are prospective solutions and may be reasonable agrotechnical options. This research was undertaken because of the potentially high productivity of the 'afila' morphotype in good wheat complex soils. The aim of the study was to determine the effect of vaccination with <em>Rhizobium</em> and foliar micronutrient fertilization on yield of the afila pea variety. The research was based on a two-year (2009–2010) controlled field experiment, conducted in four replicates and carried out on the experimental field of the Bayer company located in Modzurów, Silesian region. experimental field soil was Umbrisol – slightly degraded chernozem, formed from loess. Nitragina inoculant, as a source of symbiotic bacteria, was applied before sowing seeds. Green area index (GAI) of the canopy, photosynthetically active radiation (PAR), and normalized difference vegetation index (NDVI) were determined at characteristic growth stages. The presented results of this study on symbiotic nitrogen fixation by leguminous plants show that the combined application of Nitragina and Photrel was the best combination for productivity. Remote measurements of the pea canopy indexes indicated the formation of the optimum leaf area which effectively used photosynthetically active radiation. The use of Nitragina as a donor of effective <em>Rhizobium</em> for pea plants resulted in slightly higher GAI values and the optimization of PAR and NDVI. It is not recommended to use foliar fertilizers or Nitragina separately due to the slowing of pea productivity.

<p>Salinity stress is one of the most important plant stresses in Iran. In this regard, a factorial experiment was conducted to investigate the effects of salinity stress on the garden pansy. The investigated factors were containing sodium selenate (0, 2, 4 and 8 mg l<sup>-1</sup>), its method of application (foliar and soil applications) and salinity stress (0, 3 and 6 dS m<sup>-1</sup>). The obtained results indicated that salinity leads to the significant reduction in morphological traits, chlorophyll a and b contents. Under the salinity of 6 dS m<sup>-1</sup>, when sodium selenate was used in the soil, the fresh and dry mass of flower increased by 11.34 and 10.39 %, respectively, compared to the control. However, the use of sodium selenate by foliar application led to the increasing fresh and dry mass of garden pansy’s flower by 25.10 and 25.41 %, respectively. Also, the content of chlorophyll a increased by 12.93 % under the salinity of 6 dS m-1 with applying 8 mg l<sup>-1</sup>sodium selenate compared to the case of non-application. The superoxide dismutase activity decreased by 26.13 % compared to the non-sodium selenate usage treatment. In conclusion the foliar application of sodium selenate at the concentraion of 8 mg l<sup>-1</sup> resulted in the garden pansy’s growth improvement.</p>

Calendula Officinalis L

Effect of gibberellic acidon marigold (Calendula Officinalis L.) was evaluated in a pot culture experiment. A factorial experiment based on completely randomized design including 12 treatments and four replications was carried out. Main factor was foliar application stages (first, second and third) and sub factor included different concentrations of GA3(0, 50, 150 and 250 mg L-1). Results showed that foliar application of GA3had positive effect on photosynthetic pigments. Effect of different concentrations of GA3on chlorophyll a was significant (p<0.01). Chlorophyll a content was enhanced by increase in GA3concentration up to 250 mg L-1 treatment of 250mg L-1 resulted in production of 7.78­µg/L-1chlorophyll a, the index which was to some extent dropped in other concentrations. Different concentrations of GA3 had significant effect on chlorophyll b (p<0.01). Chlorophyll b was increased by increase in GA3concentration up to 250mgL-1. the highest rate of total chlorophyll content and total pigment in three times of application and one application of 250 mg L-1 was 14.6 and 15.4 µg/L-1 respectively; whereas the lowest chlorophyll and pigment content was observed in one foliar application of control treatment with mean value as 4.67 and 5.5 µg/L-1.

The paper presents the results of the effect of different fertilizers on concentration of photosynthetic pigments in leaves of juvenile seedlings of Eastern black walnut (Juglans nigra L.). The seedlings were produced in 2014 in the seedling nursery of Institute of forestry in Belgrade. The trial was set up in a random block system with three types of fertilizers and a control in three replications. Three types of pigments have been examined: chlorophyll a, chlorophyll b and carotenoids. The leaf sampling was carried out in the beginning of June 2014. The highest concentration of photosynthetic pigments was found in the leaves of seedlings treated with the preparation Osmocote® Exact Standard 5-6 M and the lowest in the seedlings which were not treated. The highest mean value had chlorophyll a (0.522mg/g) in treatment with Osmocote® Exact Standard 5-6 M and the lowest mean value had chlorophyll b (0.213mg/g) in the control sample. The results showed that the concentration of photosynthetic pigments in leaves of Eastern black walnut juvenile seedlings varied depending on the fertilizer that was applied. Based on the obtained results it can be concluded that the proper fertilizer can increase the concentration of photosynthetic pigments in leaves and therefore the intensity of photosynthesis which contributes to increasing the biomass production.
