Abstract
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.
