摘要

背景:当矿物质营养素过量或不足时,它们对植物的影响可能是严重的,可以被认为是一种非生物胁迫。在这项研究中,我们报告了大麦品种的激素水平如何响应硼的毒性作用,硼是一种必需的植物微量营养素。材料与方法:以两种不同品种的大麦(Hordeum vulgare) (Vamik Hoca和Efes 98)为研究材料。硼以三种不同浓度(0、10、20 ppm)施用于从种子生长四周的植物。收获植株,测定茎根长度和茎根干鲜重含量。叶绿素、总蛋白、内源IAA和ABA含量分析。结果:植物的生长发育随硼浓度的增加而降低。随着硼浓度的增加,两个品种的可溶性总蛋白含量均有所增加。硼处理使两个品种的内源IAA含量增加。施用10和20 ppm硼后,Vamik Hoca品种的内源ABA含量增加,而Efes 98的内源ABA含量下降。不施用硼导致两个品种内源IAA和ABA含量增加。结论:两个品种对硼的反应不同,Efes 98可能比Vamik Hoca品种对硼的抗性更强。

Does boron affect hormone levels of barley cultivars
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 a n d 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.
