According to statistics, Petunia became the most used flower specie for summer and autumnal decor of parks and gardens. The degree of branching of the plant is a characteristic of variety but as well branching plant is influenced by the number of applied top pinching shoots. Our experiments were focused on study of reaction of four new varieties of Petunia ('Veranda Scarlet', 'Picotte Purple', 'Surfinia Blue', 'Shishi Purple') to pinching shoots. We used rooted cuttings of each variety that off the top over the 4-8 leaf growth (from 2.5 to 4 cm). Shoots arising from these were pinching pinch in the same way (every month) and repeated pinching and secondary shoots. The effect of pinching to quantify the observations, measurements and determination of the main indicators of growth and flowering plants: the number and length of shoots on the degree of branching, leaf number, plant height and diameter, number of buds and flowers. In terms of vegetative growths responded best plants of the varieties 'Picotte Purple' and 'Blue Surfinia' who had higher values of the indicators of growth right from the first pinch. In quality flowering best results were obtained from varieties 'Picotte Purple' and 'Veranda Scarlet'. These results attest to the fact that pinching of the shoots often has a positive impact on the formation, growth and flowering of petunia plants, plant response to these works is different depending on variety.
