The impact of growth conditions on the fluorescent characteristics of the leaves of the vegetable and cultivated oilseed forms of soybean (Glycine max (L.) Merr.), which were introduced in central Russia for the first time, was studied. The following parameters of fluorescence induction were used: NPQ (nonphotochemical fluorescence quenching), qP (photochemical fluorescence quenching), Q_y (actual quantum yield of photochemical reactions in photosystem II), Qy_max (maximum quantum efficiency of photosystem II), and Rfd (vitality coefficient). Using soybean plants in the flowering and technical ripeness phases as an example a direct relationship between nonphotochemical quenching and the Rfd indicator (r = 0.95), as well as an inverse relationship between the F_v indicator with photochemical quenching (r = –0.89 and r = –0.78 in the flowering and technical ripeness phases, respectively) was shown. The biochemical parameters were studied and their correlation with the photosynthetic parameters of the leaves of vegetable forms of soybean was analyzed. As an example, the accumulation of antioxidants had approximately the same moderate degree of correlation (r = 0.40) with Qy_max, Rfd, and qR_stat. At the end of the growing season, the correlation of the vitality coefficient in the technical ripeness phase with the productivity of vegetable soybean in the phase of full biological ripeness, namely, the weight of the plant (including the underground part), the number of beans per plant, and the weight of seeds per plant, were analyzed. There was a stable positive correlation between these indicators from r = 0.78 (with the mass of the plant and the mass of seeds from the plant) to 0.90 (with the number of beans per plant). The vitality coefficient has practical significance, playing the role of a quantitative characteristic of plant productivity, which makes it possible to use PAM fluorimetry in the assessment of the physiological state of a plant organism and its economic efficiency.

研究了生长条件对首次引入俄罗斯中部的蔬菜和栽培油籽形式大豆（Glycine max (L.) Merr.）叶片荧光特性的影响。使用以下荧光诱导参数：NPQ（非光化学荧光猝灭）、qP（光化学荧光猝灭）、Q _y（光系统 II 中光化学反应的实际量子产率）、Qy _max（光系统 II 的最大量子效率）和Rfd（活力系数）。以处于开花和技术成熟阶段的大豆植物为例，说明非光化学淬灭与Rfd指标 ( r = 0.95)之间的直接关系，以及F _v指标与光化学淬灭之间的反比关系( r = –0.89 和r = –0.78 在开花和技术成熟阶段，分别）。研究了生化参数，并分析了它们与植物性大豆叶片光合参数的相关性。例如，抗氧化剂的积累与Qy具有大致相同的中等相关程度 ( r = 0.40)_max、Rfd和qR _stat。生长季末技术成熟期活力系数与全生物成熟期植物性大豆生产力的相关性，即植株重量（含地下部分）、分析了每株植物的豆类和每株植物的种子重量。从r来看，这些指标之间存在稳定的正相关关系= 0.78（植物的质量和植物种子的质量）到 0.90（每株植物的豆数）。活力系数具有实际意义，起着植物生产力的定量特征的作用，这使得利用PAM荧光法评估植物生物体的生理状态及其经济效益成为可能。
