Influence of prolonged fertilizers on the subsequent blackberry seedlings growth after in vitro |
|
|
The demand for blackberry planting material (Rubus Eubatus Focke) is increasing every year. The purpose of our study is to evaluate the effect of fertilizers on the subsequent blackberry seedlings growing ex vitro. The objects of the study were blackberry varieties ‘Natchez’ and ‘Chester Thornless’, as well as fertilizers Osmocote Exact Standard High K and OMF (organo-mineral fertilizers) for fruit and berry crops. The seedlings were grown in P9 pots (0.5l). As a result of the research, it was found that the root systems in all variants have a low variation, and the shoots’ length varies from 20 to 30%. It was established a significant influence of the factors’ interaction on the root system’s volume and the roots’ number, as well as on the shoots’ number and its length. In comparison with OMF, the roots number with Osmocote fertilizers is increased in two times. For its part, OMF significantly affects the roots length’s increase.
