Studying of buds properties such as earlу-maturity, shoot restoring ability, allows to under-stand deeply natural growth and plant development above the ground, its restoring and to substantiate agrotechnical methods. Activity degree of indicated properties of different sorts and varieties are not the same. As a result on the rate formation and the following buds development of Japanese quince in the conditions of the partially-wooded steppe of Omsk Region influence not only hereditary proper-ties of plants but also the weather conditions in the vegetation period. The dependence of variation number of early-maturing buds upon the growth rate has been established. There are some groups selected according to the ability of the studied form of Japanese quince to the formation of early-maturing buds: forming early-maturing buds yearly; forming them under certain conditions; incapable to form early-maturing buds. The studying of shoot restoring ability of Japanese quince allowed to give the recommendations for the height of cutting fro-zen branches of forms with low and high restoration degree, allowing to avoid thickening of bushes.
