Sažetak
The influence of the rhizobacterium Azospirillum brasilense on the vegetative activity of MaxMa 14 (Prunus mahaleb x Prunus avium) rootstocks, a widely used sweet cherry rootstock in semi- intensive orchards, was determined. The field experiment was conducted on one-year-old micropropagated rootstocks in 3L pots, arranged to randomized block design in 3 repetitions, and 15 pots in row per each repetition. Vegetative growth promoter AZOS® that contains single rhizobacterium A. brasilense was added by watering to plants in concentration of 0 g/l (T0 control), 0.8g/l once a month (T1) and 0.8g/l every two months (T2) in controlled time intervals. Plant height, trunk cross-section area (TCSA), shoot number and chlorophyll content index (CCI) were observed as factors of vegetative activity. Also, vegetative growth of 3 individual shoots and number of their internodes was measured three times during vegetation. Based on the obtained research results, it was determined that the use of A. brasilense by watering rootstock seedlings affected vegetative activity. Plant height, TCSA, CCI, shoot length and internode number were influenced by A. brasilense while shoot number wasn’t influenced by rhizobacteria. In conclusion, watering MaxMa 14 rootstocks with A. brasilense could be useful for obtaining quality grafting material.
