Influence of biological products on the parameters of the root system of wood cuttings of black currant (Ribes nigrum L.) |
|
|
Black currant (Ribes nigrum L.) is one of the most widespread berry crops in Russia. The need for planting material of black currant is increasing every year, because the area for laying industrial plantations is increasing. The purpose of our research is to assess the effect of combinations of biological products on the rooting rate of cuttings and on the parameters of the root system of black currant. The objects of research are black currant varieties - Dar Smolyaninova, Sevchanka, Yadrenaya. In the research, there are two combinations of biological products: based on Trichoderma viride + water and the combined use Trichoderma viride and Pseudomonas fluorescens. The experiment was carried out in 2021 in the Moscow region. We found that there is no reliable effect of the products on the increase of the root system volume and the roots length. The coefficients of variation for the studied varieties of the root system volume and along the length are very high, that does not make the planting material leveled according to these indicators.
