In the conditions of the Republic of Belarus there were presented the results of the observation of the vegetation terms and growth intensity of apple (Malus) oculants of the cultivars 'Imant' (2007, 2009) and 'Byelorusskoye sladkoye' (2007, 2009-2010) in the second nursery field. Weather conditions of cultivation and growth activity of plants dynamics were analyzed. The period of the basic plants growth and cultivar distinctions in its intensity was determined. It was established that in a growth period of plants, the intensity of oculants of the cultivar 'Byelorusskoye sladkoye' was higher by 1,2 – 1,5 times in comparison with the oculants of the cultivar 'lmant'. The weather conditions most influencing on plants height in a growth period were defined by means of correlation analysis. For the oculants of the studied cultivars a positive dependence between plants height and moisture conditions (correlation coefficients 1 and 0,999) was established.
