Nana variety was obtained in Romania from a Crişana clone at the Research and Development Station for Fruit Tree Growing Băneasa. It is a variety with a wide ecological plasticity, cultivated throughout the country. The fruit is red burgundy, medium size, with spherical shape. Harvest at maturity starts at the end of June and lasts until the end of July. The study presents the comparative analysis of Nana cherry-tree variety when applied the biostimulator ASFAC BC04 and in its absence. The aim of the study was to highlight the morphological, biochemical and productivity differences of Nana cherry-tree variety with and without treatment. We determined some morphological parameters of fruits and stems, fruits and stems biomass, some biochemical parameters (dry matter and water content, sugar content, acidity), assimilation of leaf pigment content. After the treatment with the biostimulator ASFAC BC04 there was an increase in some analysed parameters: fruit weight (3.31%); sugar content (1.11° Brix), chlorophyll content (0.057 mg/g).
