摘要
在 "Bolshiye Mochazhiny "地区发现了萨拉托夫州三种珍稀保护植物(Gladiolus tenuis、Iris halophila 和 Dactylorrhiza incarnata)的族群。这些物种在邻近地区(坦波夫州、沃罗涅日州、奔萨州等)也受到保护。这些物种具有很高的观赏价值,这是植物生态范围狭窄之外的另一个因素。G. tenuis、I. halophila 和 D. incarnata 对水分和土壤肥力的要求较高,数量较多,并具有创造性。所研究植物的种群有一个自我更新的过程,这并没有受到人为因素的阻碍,因为该地区远离居民点,有些地方还是沼泽地。稀有物种的形态指数与其生物学特性相符。物种种群的个体发育状况以单峰谱为特征,其中世代分化个体所占比例较高:G. tenuis为49.4%,D. incarnate为40.0%,I. halophila为62.2%。根据 T. A. Rabotnov 的分类,所研究物种的种群属于正常的不完全型。根据 L. A. Zhivotovsky 的 delta-omega 分类法,G. tenuis 和 D. incarnata 的种群属于老龄种群;而 I. halophile 的种群属于老龄种群。所研究的珍稀植物种群在时间和空间上都很稳定。有必要宣布 "Bolshiye Mochazhiny "地块为具有地区重要性的自然遗迹。
Status of rare plant cenopopulations of the tract “Bolshiye Mochazhiny” in Balashov district, Saratov region
Cenopopulations of three rare and protected plants of the Saratov region (Gladiolus tenuis, Iris halophila, and Dactylorrhiza incarnata) were found in the tract “Bolshiye Mochazhiny”. These species are protected in neighboring regions as well – the Tambov, Voronezh, Penza regions and others. The species are of high ornamental value, which is another factor besides the narrow ecological amplitude of the plants. G. tenuis, I. halophila, and D. incarnata are demanding to moisture and soil fertility, have high numbers, and create aspects. In the cenopopulations of the studied plants a process of self-renewal proceeds, which is not hampered by anthropogenic factors, as the tract is far from settlements and is swampy in some places. The morphometric indices of the rare species correspond to their biology. The ontogenetic status of the species cenopopulations is characterized by a single-vertex spectrum with a high proportion of individuals of generative fractions: 49.4% for G. tenuis, 40.0% for D. incarnate, and 62.2% for I. halophila, respectively. According to T. A. Rabotnov’s classification, the cenopopopulations of the studied species are normal incomplete-membered. According to L. A. Zhivotovsky’s delta–omega classification, the cenopopulations of G. tenuis and D. incarnata are old; while that of I. halophile is aging. The studied cenopopulations of rare plants are stable in time and space. It is necessary to declare the tract “Bolshiye Mochazhiny” a natural monument of regional importance.
