It grows as a part of Amygdalus bucharica and Perovskia scrophulariifolia formation, where the total projective cover of grass does not exceed 20%. In natural conditions growth, ontogeny of L. proskorjakovii is simple and complete. The duration of ontogenesis in the condition of Nuratau is no more than 22 - 23 years. Studied coenopopulations are normal, but are not complete. Coenopopulation self-maintenance is carried out by the seed of renewal. The characteristic spectrum of coenopopulation centered, with a peak in the middle-generative individuals. In most cases, specific developmental spectrum of coenopopulation coincides with the characteristic ones. The absence or small proportion of the young fraction in surveyed of coenopopulation is related to the elimination of young fragile individuals. According to the classification of “delta-omega”, the most of coenopopulations are maturing which confirms the positive state of coenopopulation demography. Studied the ontogeny and structure of adult endemic Nuratau established that the species belongs to caudexum shrubs, perennial that forms the axis of the short multicipital caudex. Buds renewal is at a height of 2 - 3 cm above the substrate. Investigated coenopopulations L. proskorjakovii are successiveness conditions.

Bioecological features, morphological and anatomical characteristics of Crocus korolkovii were studied. Phenology was studied by I.N. Beideman, biology bloom by A.P. Ponomarev, breeding and seed production of plants by T.T. Rakhimova. The study of the biology of flowering determined the optimal humidity, air temperature and soil surface. The anatomic study used fresh tissue samples which were fixed in 70% alcohol. A cross-section of the sheet and the structure of the flower in the introduction of conditions were studied.展开更多

Within the western part of the area (Kyzylkum desert) in different ecological and phytocenotic conditions, 8 coenotic populations of the species were identified. Based on the number of organism and population traits, the current state of coenotic populations of the species was evaluated. It was revealed that the vast majority of coenopopulations are in pessimal state. Coenopopulation only growing on the eastern part of the mountain Kuljuktau was assessed as optimal.展开更多

Usually it grows on eroded clay soils among sparse juniper forests in the middle mountain belt. Studied coenopopulations of S. lilacinocoerulea are normal, but are not complete. Coenopopulations self-maintenance is carried out by the seed of renewal. The characteristic spectrum of S. lilacinocoerulea coenopopulation is centered, with a peak in the middle-generative individuals. In most cases, specific developmental spectrum of coenopopulation does not coincide with the characteristic ones. The demography structure of mostly investigated coenopopulations is satisfactory. The population growing on the grey clay soil, on strongly eroded slope among sparse juniper woodland was evaluated as critical due to absence in ontogenetic spectrum young individuals and small percentage of generative plant as well.展开更多
