The assessment of bio-ecological features of plants <i>Tulipa biebersteiniana</i> Schult. et Schult. fil. in the model forest habitats of the Krasnosamarsky forest

The paper presents some preliminary results of the monitoring ofTulipa biebersteinianaSchult. et Schult. fil. plants (category of rare and endangered plant species). By summarizing the available sources of science literature we have compiled a general description of morphological and bio-ecological species characteristics. The results of the field study fulfilled in 20122015 in two population groups of the Krasnosamarsky forestry (Samara region) were used to determine morphometric parameters ofTulipa biebersteinianaplants. The data also helped us to assess the variability level and to make a comparison with plant quantitative traits given in the literature. It was found that the shoot length ofTulipa biebersteinianaplants varied in the range of 23 50 cm, the maximum average length of 40 cm are presented in plants of population group number two.The distribution of shoot length among individuals of the second population group is more stable, changes depending on the year of vegetation are poorly expressed.The lengths of shoots inside the range specified for the various parts of the area in the literature with a significant proportion of high plants in the population is studied. This may be a sign of good growth conditions forFritillaria ruthenicathat gives an opportunity to the plant conservation in natural communities in the absence of limiting anthropogenic factors.
