摘要
摘要目的是研究天然信号分子水杨酸(SA)和枯草芽孢杆菌(Bs)对 Willd.金盏花植物材料(叶片)中光合色素(PhSP)比例及其装饰性的作用效果。研究方法利用分光光度法,分析了生长季节期间,在俄罗斯科学院联邦研究中心(乌法)巴什基尔农业科学研究所从巴什科尔托斯坦共和国耕地土层中分离出的枯草芽孢杆菌菌株及其与水杨酸结合的影响下,色素(叶绿素a、叶绿素b和类胡萝卜素)含量的动态变化。科学新颖性。研究了单独使用枯草芽孢杆菌菌株以及与水杨酸一起使用对巴什基尔中乌拉尔地区金盏花的生理参数和装饰特性的影响。研究结果对动态(萌芽期、开花期和结果期)中 PhSP 的含量和比例进行了分析。结果表明,在开花期,给 C. alliariifolia 植物接种枯草芽孢杆菌会显著增加类胡萝卜素的含量。在结果期,Bs + SA 试验变体的 PhSP 含量最高。双因素方差分析表明,对于所研究的指标,因素A(植被期)、因素B(不同的实验方案)以及两个因素(A × B)的总影响程度对金钟罩叶片样本中PhSP含量的显著影响具有统计学意义。研究发现,接种枯草芽孢杆菌菌株能最大限度地提高开花量和铃兰花花序密度等指标,从而提高 C. alliariifolia 在巴什基尔-西乌拉尔条件下的装饰性。
Impact of biological growth regulators on the ratio of photosynthetic pigments of Campanula alliariifolia
Abstract. The purpose is to study the effectiveness of the action of the natural signaling molecule salicylic acid (SA) and Bacillus subtilis (Bs) on the ratio of photosynthetic pigments (PhSP) in plant materials (leaves) of Campanula alliariifolia Willd. and its decorativeness. Methods. Using spectrophotometric techniques, an analysis was carried out of the dynamics of the content of pigments (chlorophyll a, chlorophyll b and carotenoids) under the influence of a strain of the bacterium Bacillus subtilis, isolated at the Bashkir Scientific Research Institute of Agriculture of the Federal Research Center of the Russian Academy of Sciences (Ufa) from the arable soil layer of the Republic of Bashkortostan, and its combination with salicylic acid during the growing season. Scientific novelty. The influence of the B. subtilis strain separately and together with salicylic acid on the physiological parameters and decorative properties of Campanula alliariifolia in the conditions of the Bashkir Cis-Ural was studied. Results. The content and ratio of PhSP in dynamics (phases of budding, flowering and fruiting) were analyzed. It was revealed that inoculation of C. alliariifolia plants with Bacillus subtilis significantly increases the amount of carotenoids during the flowering phase. During the fruiting phase, the maximum content of PhSP was noted in the Bs + SA variant of the experiment. Two-factor analysis of variance showed that the significant influence of factor A (vegetation phase), factor B (different experimental options), and the degree of total influence of two factors (A × B) on the content of PhSP in samples of campanula leaves is statistically significant for the studied indicators. It was found that inoculation with the B. subtilis strain maximized indicators such as the abundance of flowering and the density of bellflower inflorescences, thereby improving the decorativeness of C. alliariifolia in the conditions of the Bashkir Cis-Ural.
