The aim of this study was to determine the influence of different pH values of water solution (pH 4.5, 5.5, 6.5, 7.5 and 8.5) and temperatures (10, 15 and 20 ºC) on fibre flax seed germination and seedlings morphological characteristic (seedling root and stem length and total seedling length). The study was conducted in the controlled conditions by rolled filter paper in 4 replicates for 7 days. The average germination rate of flax seed was 84%. The highest germination rate was found at 20 ºC (88%) which was very significant (P<0.01) as compared to germination rate at 10 ºC where it was decreased by 9%. The highest share of normal seedlings was determined at pH 5.5 (70%) and the lowest at pH 8.5 (59%).There was no statistically significant influence of different pH on morphological characteristic of fibre flax seedlings (seedling root and stem length and total seedling length). The statistically significant difference (P<0.01) was determined in the length of the seedlings depending on the temperature, whereby after 7 days the largest seedlings were developed at 20 ºC (14.4 cm) and the shortest at 10 ºC (2.1 cm). In general, the lowest pH value (4.5) as well as the highest pH value (8.5) in this study resulted in a lower share of normal and healthy seedlings (63% and 59% respectively) and compared with seedlings of other pH values they developed a smaller root and stem.

This study analyzes the dynamics of sugar beet root, crown, and leaves fresh and dry matter (FM and DM, respectively) accumulation per plant and their mass ratio at different plant densities and nitrogen fertilization. The biennial field trials were set as four different planting densities (60,000, 80,000, 100,000 and 140,000 plants ha-1) and three methods of nitrogen application in spring: control – without nitrogen fertilization (N0), presowing only (N1), and presowing with topdressing (N2). Close to the maturation, the mean DM of the whole root, crown, and leaves on September 20, 2014 amounted to 28.8, 7.3 and 4.0 t ha-1, respectively, whereas it amounted to 20.7, 4.1 and 2.3 t ha-1 in 2015, respectively. Moreover, with regard to the plant densities, the highest root DM was at 140,000 and 100,000 (31.6 t ha-1 in 2014 and 22.4 t ha-1 in 2015), compared to the wider plant densities of 80,000 and 60,000 plants ha-1 (22.4 t ha-1 in 2014 and 18.1 t ha-1 in 2015). Nitrogen fertilization positively influenced on dry matter accumulation, but it was different within the years. On September 20, 2014, a presowing fertilization (N1) increased the root DM by 17%, compared to the control, whereas in 2015 the presowing with topdressing (N2) increased the root DM by 30%. The root-to-leaves FM ratio amounted to 1:3.9 on May 30, 2014, whereas it amounted to 1:0.1 on September 20, 2014. The leaves FM was at its largest on June 20, 2015, when the root-to-leaves ratio amounted to 1:1.1, and gradually decreased to 1:0.1 on September 20, 2015.

In this research there were studied the effects of NaCl-induced salinity and environment temperatures on germination and seedlings growth of domestic poppy. The study was conducted in the controlled conditions in the plant growth chamber. There were applied different concentrations of NaCl (0 mM (control), 50 mM, 100 mM and 150 mM) and environment temperatures (10°C, 15°C and 20°C). The 50 seeds of domestic poppy cultivar (Detkovac) were sown in 4 replicates on the filter paper. The germination energy was determined on the 5th day and total germination rate and seedlings morphological characteristic were determined on the 10th day. At the 5th day germination energy was on average 28%. It was interesting to note that at the 10°C there were no germinated seeds after 5 days at all salinity treatments and also, at the salinity level of 150 mM NaCl at every temperature. The average germination rate (on 10th day) of domestic poppy seeds were 52% and it varied from 30% (150 mM NaCl and 20°C) to 90% (0 mM NaCl and 15°C). Different salinity of water solution had a very significant (p<0.01) influence on stem, root and total length (cm) of seedlings. The average root length was 1.3 cm and it varied from 0.9 cm (100 mM NaCl) to 1.8 cm (0 NaCl). The average stem length was 1.8 cm. The longest stem was found at control (2.7 cm), and between 50 and 100 mM of NaCl the difference was not significant and stem length averaged 1.4 to 1.3 cm depending on the temperature. Average total poppy seedlings length of this study was 3.0 cm and it varied from 4.5 cm at the control to 2.3 cm at 100 mM NaCl. With regard to temperatures, there was no significant differences found in root and total length of poppy seedlings, but the differences were very significant (p<0.01) for stem length. The longest poppy seedlings were measured at 20°C and 0 mM NaCl (4.9 cm), while at 10°C and at 0 or 50 mM NaCl, seedlings were less than 0.1 cm. Seeds were not germinating at all on 10°C on both, 100 and 150 mM NaCl. Generally, salinity reduced germination energy and germination rate and seedlings length. Results may indicate that seeds are mainly affected by osmotic stress and therefore it is not recommended to cultivate poppies on soils with excess salts
