    Opis:
    The present research was conducted to evaluate the effects of salinized water with NaCl on seed germina- tion of Periwinkle and Corn Poppy. Treatments were: A) H2O- distilled water (control); B) sodium chloride solutions (5, 10, 20, 40 and 80 mM). Application of the highest NaCl concentration (80mM) significantly reduced germination percentage and mean germination time of both species, although increased the day of 50% germination. Increment of salinity concentration was led to the reduction of radicle length in Periwinkle. The seedling fresh weight and water content and radicle length of Corn Poppy were decreased in both levels of 20 and 80 mM, and seedling dry weight was unaffected by treatments. It is concluded that both species are tolerant to NaCl salinity up to 80 mM during germination stage.

    Opis:
    The herbicidal potentials of the aqueous extracts of the leaves of Senna siamea and Pinus carribaea on the germination and seedling growth of Euphorbia heterophylla were investigated. The results showed that the leaf aqueous extracts of the two plants brought about considerable inhibition on the germination of E. heterophylla seeds and reduction in the radicle and plumule lengths of E. heterophylla seedlings. The degree of inhibition increased with increase in the concentration of the extracts, thus suggesting that the effect of the extracts were concentration dependent. The results obtained revealed that the inhibition was pronounced in both extracts such that no germination of E. heterophylla seeds and plumule occurred until 48hrs and 96hrs of the experiment respectively. It was apparent that Senna siamea extracts had more inhibitory effect on E. heterophylla seeds than those of Pinus carribaea treated seeds as no radicle growth was clearly observed in the Senna siamea treated seeds until 72hours experimental time whereas in Pinus carribaea treated seeds, radicle growth was observed at 48hours of the experiment. Statistical analysis (P < 0.05) revealed that significant differences were observed in the germination, radicle and plumule lengths of the two extracts treated seeds when compared to the control experiments. The inhibitory effects of the aqueous extracts derived from the leaves of Senna siamea and Pinus carribaea might be useful in the control of E. heterophylla in farmlands. Further studies should be carried out to ascertain the bio- herbicidal potentials of these plants.

    Opis:
    The aim of the study was to determine the effect of soil contamination with diesel oil on the early development of three species of the Fabaceae family (Medicago lupulina L., Lotus corniculatus L., Trifolium repens L.). These species have a wide ecological range and they often occur on extensively used lawns. For these reasons, the knowledge on their tolerance to soil pollution with diesel oil can be of great importance in the creative and conservative cultivation of these plant species and their seed production for establishing the greenery of communication routes. The studies were carried out under controlled laboratory conditions. The soil substrates were composed of the loamy sand mixed with diesel oil in an amount of 2.5 g and 5.0 g per 1 kg of absolute dry mass of soil. The germination dynamics were analyzed. The measurements were conducted twice a day for 12 days after sowing. The development of seedlings was determined on the basis of the length, diameter, area and volume of the radicle. These features were determined on 20-day-old seedlings of the tested species. For the analysis of plant material, the technique of the scanned image was used in the “WinRhizo PRO 2009” software. It was proven that the tested species have various tolerances for the petrol oil in the soil and demonstrate various defense mechanisms under the stress conditions. The least changes of the seed germination rate on the soil with diesel oil against the control were indicated for L. corniculatus. The defense strategy of that species relied on the radicle development through increasing the diameter and – in consequence – the surface and the volume. M. lupulina also showed good germination capacity in the presence of diesel oil, but the radicle was shorter in comparison to the control. The germination rate of T. repens in the contaminated soil was significantly reduced. The recommendation for using not only L. corniculatus, but also M. lupulina on the contaminated areas should be taken into consideration.
