“…In contrast, ABA stimulates root growth (Sharp et al 1994). In a study with carrot (Daucus carota L.) root callus under boron stress, ABA content increased (Demiray and Dereboylu 2006). Our results showed that boron deficient application groups had higher hormone content than excess boron applied groups.…”

Background: When mineral nutrients are present in excess or in inadequate amounts, their effects can be severe in plants and can be considered as abiotic stress. In this study, we report how hormonal levels in barley cultivars respond to the toxic effect of boron, an essential plant micronutrient. Materials and Methods: Two different barley (Hordeum vulgare) cultivars (Vamik Hoca and Efes 98) were used as a study material. Boron was applied in three different concentrations (0, 10, 20 ppm) to plants that had grown from seeds for four weeks. Plants were harvested, stem-root length and stem-root dry-fresh weight content were determined. For further analysis, chlorophyll, total protein, endogenic IAA and ABA content analyses were carried out. Results: According to the data obtained, plant growth and development decreased with increasing boron concentrations. With increasing boron concentrations, soluble total protein increased in both cultivars. Boron application led to increased endogenic IAA content in both cultivars. 10 and 20 ppm boron application led to increased endogenic ABA content in Vamik Hoca cultivar whereas endogenic ABA content decreased in Efes 98. Absence of boron application led to increased endogenic IAA and ABA content in both cultivars. Conclusions: As a result, the response to boron is different in the two cultivars and Efes 98 may be more resistant to the toxicity than Vamik Hoca cultivar.

“…[22] Similarly, in a study with carrot (Daucus carota L.) root callus under boron stress, the ABA content also increased. [26] It is presumed that ABA might bind to an apoplastic locus of ABA perception site, inducing an internal calcium-based signal transduction cascade, causing stomatal closure. [27,28] This is a well-known cellular response to abiotic stress conditions.…”

Potato crop production in Turkey ranks on the thirteenth place in the world. Toxicity is a problematic issue for some parts of the Turkish soils. Hence, it is very important to clarify the physiological responses of plants to toxic mineral stress. In this study, two different potato cultivars À Solanum tuberosum cv. Resy and Solanum tuberosum cv. Agria À were used as a study material. Excess boron was applied in two different concentrations (5 mmol/L and 12.5 mmol/L) 32 days after planting the tubers. Plants were harvested at the end of 15 days of excess boron application. Chlorophyll fluorescence (Fv/ Fm) was measured. Shoot height and shootÀroot fresh weight contents were determined. Analyses were carried out for the contents of the endogenous hormones indole-3-acetic acid (IAA) and abscisic acid (ABA) by using gas chromatographymass spectrophotometry (GS-MS). According to the obtained data, plants' shoot height did not change, whereas the shoot's fresh weight decreased significantly with increasing of the boron concentrations in cv Resy, by applying 12.5 mmol/L boron. With 12.5 mmol/L boron, the photosynthesis was negatively affected in both cultivars. Boron application led to increased endogenous IAA and ABA content in both cultivars. As a result, cv. Resy showed more resistance to excess boron. Findings on the hormone metabolism and chlorophyll fluorescence in different cultivars will shed a light on understanding the physiological response to excess mineral stress.

“…Three types of modified MS medium (Murashige & Skoog, 1962) were used. Nutritional variants were set: (1) -basic MS supplemented with the addition of 310 mg of H3BO3 and 25 mg of nicotinic acid (Demiray & Dereboylu, 2006); (2) -basic MS medium of Styrax with 0.5 mg of BAP plus 1 mg of NAA and 10 mMol of thiamine pyrophosphate chloride (cocarboxylase) to initiate callus; (3) -basic MS medium supplemented with 0.5 mg of BAP plus 1 mg of NAA as control medium, as a second medium, and as a third medium.…”

The stem tissue of Styrax officinalis L. distributed in West Anatolia was induced with agents such as boric acid and cocarboxylase (thiamine diphosphate), extensive stimulators of resin channels, in order to increase the amount of benzoin volatile oil. While the benzoin content was 120% in the induction medium to which excess boron and niacin were added, it increased to 231% when cocarboxylase (thiamine diphosphate) was added to the medium. Benzoin content of Styrax from petiole calli was 166%. HPLC-DAD results revealed that benzoin resin was present in 90% of the stems of Styrax officinalis distributed in West Anatolia. The major components of excess boron-and niacin-induced stem calli were hexane (58.33%), 3-methyl 2-pentene (16.10%), and cyclohexane (8.88%). Hexane (62%), methyl cyclopentane (19.09%), cyclohexane (12.04%), 2-hexanone (0.04%), ethylbenzene (0.03%), and benzene and 1-chloro-2-methylpropyl benzene (propene) were identified by the cocarboxylase application and GC-MS method. With enzyme application, while the percentages of decane and benzyl alcohol decreased, the cyclohexane ratio increased to 12.04%. Acetone (0.03%), ethyl acetate (4.10%), and dichloro methane (0.17%) contents were high as well.
