Chaenomeles maulei C.K. Schneid - perspective introduced plant in the conditions of the Republic of Bashkortostan

Aim. To study the soil conditions of growth and assess the ability of Chaenomeles maulei to generative reproduction and fruiting in the conditions of the Republic of Bashkortostan. Methods. The objects of research are anthropogenically transformed soils and bushes Chaenomeles maulei C.K. Schneid. Studies were carried out at the site of the Republican Children's Ecological and Biological Center in Ufa and the Republican Forest Soil-Chemical Laboratory of the Ministry of Forestry of the Republic of Bashkortostan. Soil analyzes were carried out according to standardized and generally accepted methods of soil practice. Productivity and sowing qualities of seeds were studied by standard methods. Results. The physicochemical properties of anthropogenically transformed soils were studied. The features of the soil in urbanized landscapes are revealed. The morphological description of Ch. maulei with the introduction in the conditions of the Republic of Bashkortostan on urban soils, seed germination and fruit productivity was carried out. Findings. 1. Urbanized soils retain some properties of natural gray-brown soils. The surveyed layer consisting of organo-mineral material contains urban-industrial inclusions and sand particles. The granulometric composition of the soils is heavy loamy, the urbanozems studied on the main indicators of fertility correspond to the average availability. 2. Ch. maulei in the conditions of the Republic of Bashkortostan on urban soils gives full seeds with high germination (71-87%). The number of seeds in the fruit is on average 54,5 ± 3,5 (max. 84, min. 14 pcs.). 3.Fruit weight on average 21.8 g (min. 16, max. 41 g). Productivity varies greatly. Seedlings differ in shape and size of fruits; it is necessary to select highly productive forms in order to obtain varieties adapted to the conditions of the Republic of Bashkortostan.
