“…This may be due to higher concentration of Na + ions. It is well known that salinity can affect germination of seeds either by creating osmotic potential which prevent water uptake, or by toxic effects of ions on embryo viability (Lisjak et al, 2015;Wu et al, 2015;Henschke, 2016). This is also partly confirmed in our study, whereas the highest percentage of abnormal seedlings (21%) was found at pH 8.5.…”

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.

“…However, these authors described the resistance features at salinity levels between 15 and 30 g NaCl•dm -3 . Henschke [2017] defined S. caerulea and S. nutans as a halophyte, and in those grass, RWC did not decrease under the influence of salinity. Glenn [1987] also found that Spartina sp.…”

The aim of the present study was to examine physiological and morphological characteristics of Spartina pectinata 'Auremarginata' in response to various soil salinity conditions. Investigating the plant's response and time-point of potential adjustment to salinity stress will help determine the suitability of the species for growing in the roadsides. The effect of various levels of salinity on S. pectinata 'Aureomarginata' was examined. The NaCl was applied at five different levels (g•dm-3): 0 (control), 15, 30, 45, 60. The plant response was analysed after 14, 28, 42 and 56 days of the experiment. The highest concentration showed the strongest negative effects, which were indicated by a decrease in net photosynthesis rate (P N), stomatal conductance (g s), transpiration rate (E), specific leaf area (SLA), relative water content (RWC) and the number of shoots, number of young shoots and length of mature shoots. Plants have even some types of adjustment to stress conditions, at medium levels. This was especially valid for P N and g s after 28 days of the experiment. Principal component analysis revealed negative relationship of salinity level with P N , g s , E, RWC, SLA, number of young shoots and number of shoots, whereas a positive relationship was recorded with CMS, C i , number of young leaves and leaf chlorophyll content (SPAD).

“…В таких условиях, к весне, концентрация солей в почве на близлежащих территориях резко повышается, что является причиной угнетения растительности, в первую очередь травянистой, имеющей поверхностную корневую систему. Высокая концентрация солей приводит к нарушению синтеза хлорофилла и, как следствие, к уменьшению размеров листьев, постепенному их увяданию в акропетальном направлении и гибели растений [27,34,42]. Поэтому злаки, приспособленные к произрастанию в условиях повышенной засолённости и отличающиеся высокой засухоустойчивостью (Calamagrostis epigejos (L.) Roth, Leymus arenarius (L.) Hochst, Leymus racemosus (Lam.)…”
