The physiological and biochemical parameters and elemental composition of Hypogymnia physodes lichen samples from various phytocenoses differing in lighting conditions and atmospheric humidity were studied. A significant increase in the chlorophyll a and nitrogen contents, the maximal pheophytinization coefficient, and the minimum content of phenolic compounds were observed in H. physodes thalli under severe shading conditions in a spruce forest. Most of these biochemical parameters reached their minimum values with high insolation in birch and pine forests except for the content of phenolic compounds, which reached the maximum value. ICP–AES analysis of H. physodes thalli detected 20 elements (Al, B, Ba, Ca, Cd, Cr, Cu, Fe, K, Mg, Mn, Mo, Na, Pb, Sn, Sr, Tl, V, W, Zn) that were found in lichen samples from all studied natural phytocenoses except for Mo, which was absent in samples from a black alder forest. The maximum concentrations for almost half of the elements (Al, B, Fe, K, Mo, Na, Sn, Ti, V) were determined in samples from the spruce forest where the thalli were more often and consistently hydrated because of the high and more stable humidity level. A complex system of correlation relationships was established based on an analysis of cross-correlations of the physiological and biochemical parameters and the metal concentrations in the samples. The results indicated a high coordination of various physiological processes. Chlorophyll a played a crucial role in maintaining their consistency with changing environmental conditions. Its content was associated with a more significant number of different parameters and elemental concentrations.

不同植物群落的低氧健身操的复杂理化分析

研究了在光照条件和大气湿度不同的不同植物群落下的低氧健身藻地衣样品的生理生化参数和元素组成。在严重的遮荫条件下,在云杉林中观察到拟南芥的叶绿素a和氮含量,最大的脱镁叶绿素化系数和最小的酚类化合物含量显着增加。在桦木和松树林中,这些生物化学参数中的大多数达到了最小值,但酚类化合物的含量却达到最大值。拟南芥的ICP-AES分析检测到20种元素(Al,B,Ba,Ca,Cd,Cr,Cu,Fe,K,Mg,Mn,Mo,Na,Pb,Sn,Sr,Tl,V,W ,Zn)是在所有研究过的天然植物素的地衣样本中发现的,但Mo除外,而黑al木森林的样本中却没有Mo。在来自云杉林的样品中确定了几乎一半元素(Al,B,Fe,K,Mo,Na,Sn,Ti,V)的最大浓度。湿度水平更稳定。基于对生理和生化参数与样品中金属浓度的互相关分析,建立了复杂的相关关系系统。结果表明各种生理过程的高度协调。叶绿素a在维持其与不断变化的环境条件的一致性中起着至关重要的作用。
