Drought stress is one of the leading abiotic stresses that have a devastating impact on sustainable agricultural policy as a result of the decrease in crop yield. For this reason, hormones or growth regulators can be used to grow plants that can adapt to morphological and physiological changes caused by stress. Triacontanol (TRIA) is a hormone that...
Drought, which adversely affects plant growth and continuity of life and reduces product yield and quality, is one of the most common abiotic stresses at the globally. One of the polyamines that regulates plant development and reacts to abiotic stressors, including drought stress, is Putrescine (Put). This study compared the physiological and molec...
Agricultural crop affected preliminary and the most prominent by the adverse effects of global climate change have to adapt to various abiotic factors that will occur as a result of climate fluctuations in the near-future and struggle to survive. Among abiotic factors, the one of the greatest impact on plant stress is high temperature. Therefore, t...
Effects of exogenous spermidine (Spd) (10µM) application on the biochemical enzymes and molecular effects in the Burakbey cultivar of barley were investigated both normal (distilled water) and drought (-6,30 mPA PEG 6000) conditions. It is obvious that
drought stress applied to barley cultivars negatively affected plant metabolism and inhibited pla...
Cadaverine (Cad), which has an independent synthesis pathway compared to other polyamine (PA) types, contributes to the health of plants by regulating plant growth and development, abiotic stress tolerance and antioxidant defense mechanisms.

Abstract. The objective of the present study was to with all details explain of the efficiency of L-ascorbic acid (L-AsA) also known as vitamin C on cytotoxicity and geno-toxicity induced by salt stress in the barley apical meristems. As a result of the statistical analysis salt stress caused a significant (P ≤ 0.05) decrease in mitotic index of ba...
The effects of exogenous polyamines were investigated in Hordeum vulgare L. Bülbül-89 exposed to drought stress about mitotic activity, chromosome behaviors, cell cycle, and total protein content. In this study, drought stress had a reducing effect on the mitotic index and caused chromosomal abnormalities. All of the polyamines applied under drough...
Drought, which is increasing day by day with the effect of global climate change, is one of the most common environmental stresses that prevent the growth and development of plants and reduce the yield and quality of crops.

Barley seeds were kept in to 28mg/L volumes of humic acid and distilled water (control) for 24h at room temperature. Then, the seeds germinated in different salt concentrations (0.25, 0.30, 0,35 M) inside petri dishes. After the root tips were 0.5–1 cm long, they were fixed with Carnoy for 24h. To determine the effect of humic acid and salt on mito...
Over many years there have been challenging questions in plant evolutionary biology that study correlations between genome size (GS) and changing ecological parameters or climatic parameters such as latitude, longitude, or altitude. It is still a contradictory question to give an idea about genome size and altitude above sea level or geographical l...
