Determination of the Effects of Salt (Nacl) Stress on Germination in Some Barley (Hordeum Vulgare L.) Varieties
(Univ Namik Kemal, 2022) Altuner, Fevzi; Oral, Erol; Baran, Ishak
This study was carried out on the germination properties and seedling parameters effects of some NaCl doses (control (0) -50-100-150-200 mM) applied to three barley (Hordeum vulgare L.) cultivars (Kral-97: V1 - Altikat: V2 and Larende: V3). The study was carried out in the Laboratory of field crops Department of the Faculty of Agriculture of Van Yuzuncu Yil University in 2019 according to the experiment two way completely randomized design in petri dishes with 4 replications. In this study, germination and seedling characteristics of the barley cultivars under salt stress such as germination power (%), germination rate (%), germination index (%), average germination time (days), sensitivity index (%), root length (cm), stem length (cm), fresh root weight (mg), fresh stem weight (mg), dry root weight (mg) and dry stem weight (mg) were investigated. According to results of germination parameters; the effects of cultivars on germination rate and average germination time were significant. The effects of salt doses on all germination parameters were significant. The effects of varieties and NaCl interactions on the differences in all parameters were significant. According to the average, the lowest germination power and germination rates were taken from 150 mM NaCl applications and therefore it was observed that these two properties decreased by 15.56% compared to control (0). The effects of salt doses and interactions between varieties and salt doses on all parameters were significant, while the effects of varieties other than hypocotyl length were insignificant and the effects on all remaining parameters were significant. Increased salt doses have been observed to have a negative effect on all parameters. According to Salt dose averages, compared to the control group, the most affected trait from salt applications was the average germination time (82.1%) and the least affected trait was the root age weight (28.7%). It was determined that the Larende cultivar had a more salt-resistant performance in terms of all its properties, followed by the Kral-97 variety in general.
Effect of Salt Stress (Nacl) in the Triticale (X Triticosecale Wittmack) Applied Pretreatment of Gibberellic Acid
(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2019) Altuneri, Fevzi; Oral, Erol; Tuncturk, Ruveyde; Baran, Ishak
The research was conducted to determine the properties of gibberellic acid pre-treatments that reducing the negative effects of salt stress on the seeds germination of triticale (x Triticosecale Wittmack) plant under salt stress. In the study, four different gibberellic acid (0, 100, 200 and 300 ppm) and salt applications at 0, 50, 100 and 200 mM (NaCl) concentrations, a factorial experiment was conducted in completely randomized design (CRD) with four replications, In research, germination power (%), germination rate (%), germination index (%), average germination time (days), sensitivity index (%), root length (cm), stem length (cm), root fresh and dry weight (mg), shoot fresh and dry weight (mg) values were examined. According to the result of the research; when the salt concentrations increase, the germination and growth parameters of triticale were inhibited. It was seen that increasing doses of gibberellic acid pre-treatments have significant and positive effects on the germination and growth parameters of triticale seeds under salt stress. The best germination properties of triticale seeds were obtained from 300 ppm giberellic acid + 0 mM (control) salt combination.
The Impact of Salt (Nacl) Stress on Germination Characteristics of Gibberellic Acid (Ga3) Pretreated Quinoa (Chenopodium Quinoa Willd.) Seed
(Kahramanmaras Sutcu Imam Univ Rektorlugu, 2020) Oral, Erol; Altuner, Fevzi; Tuncturk, Ruveyde; Baran, Ishak
This research was conducted to examine the effects of gibberellic acid (GA3), which was treated to quiona (Chenopodium quinoa Willd) seeds before germination, on the germination and the seedling growth under saline conditions. Quinoa Titicaca variety, four different GA3 (0.0, 100, 200 and 300 ppm), and four different salt (0.0, 100 mM, 200 mM and 400 mM NaCl) concentrations of exposed stress. Germination power (%), germination ratio (%), germination index (%), mean germination time (day), sensitivity index (%) as of the second day of the research, and radicula length (cm), plumula length (cm), radicula fresh weight (mg), radicula dry weight (mg), plumula fresh weight (mg), and plumula dry weight (mg) on the 14th day were examined. The results indicated that the increasing doses of salt prevented germination and growth parameters of kinoa (Chenopodium quinoa Willd.) seeds. It was observed that the doses of GA3 (Gibberellic acid), which increased gradually before the doses of salt, affected germination and growth positively and significantly. The best results of germination characteristics of wheat seed were obtained from the combination of 300 ppm Gibberellic acid + 0 mM (control) salt.
