Morphological characteristic of fiber flax seedlings regard to different pH water solution and temperature

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.

Generative production and evaluation of ornamental plant potential of an endemic flax species for ecological landscape applications

“…The result obtained is consistent with the statement of Buranjı et al (2019), who found that the minimum germination temperature for Linum species is 2-3 C, and the optimum germination temperature is 16-18 C. Similarly, Veerhoff (1940) reported in his study on two flax cultivars that germination rates decreased significantly as the germination medium temperature increased, as in our study. In addition, there is literature which states that high temperatures slow down germination in some species (Alba et al, 2016;Núñez & Calvo, 2000).…”

“…In addition, contrary to the results we obtained in the taxon L. pamphylicum subsp. olympicum , Buranjı et al (2019) obtained a better germination rate with 20°C treatment (88%) compared to 15°C treatment (85%) on L. usitatissimum . In a study by Varga et al (2020), it was determined that L. usitatissimum seeds did not differ in germination with medium temperatures of 10°C (58%) and 20°C (59%) on the 7th day of the experiment under different salt stress conditions.…”

“…In the earlier studies with various Linum species, it has been stated that different temperature regimes affect seed water absorption and biochemical reactions, resulting in extensive differences in seed germination rate and speed (Buranjı et al, 2019; Stefanello et al, 2017). In our study, 15°C treatment generated statistically higher germination rates than 20°C temperature treatment established with cold–wet stratified seeds at 4°C for 3 months.…”

“…According to the results, it was thought that there are intrinsic dormancy (physiological dormancy as indicated by an increase in germination rate after application of GA 3 ) and exogenous dormancy caused by physical conditions in line with the report of Ashrafi et al (2013) that was found similar dormancy for L. album seeds. According to Buranjı et al (2019), Carta et al (2013), and Kırmızı et al (2018), there is physiological dormancy in Linum seeds and pretreatments are needed to break this dormancy. For example, Linum radiola seeds need time to ripen (Carta et al, 2013), Linum perenne seeds need vernalization (Meyer & Kitchen, 1994), L. olympicum seeds need cold stratification and long, dark conditions (Kırmızı et al, 2018), and Linum catharicum seeds need light and cold stratification (Milberg, 1994).…”

Yield and Yield Criteria of Flax Fiber (Linum usititassimum L.) as Influenced by Different Plant Densities

“…It is one of the oldest fiber plants in the world and is used in the production of environmental friendly durable composite materials [2,3] and paper [4] with its non-fiber wastagess. The seeds of flax plants are directly used as food in dietary products [5], as industrial oil [6], cooking oil, and the remaining residues containing rich nutritional contents are used as a food supplement [7] and as animal feed [8].…”
