Abstract. The studies aimed to assess the effect of zeolite at the stage of adaptation of microplants obtained in vitro on the growth and development of cassette plants of berry crops. The work was carried out in the Tambov region in 2019-2022. The zeolite was used in the form of a zeolite-containing mineral complex (ZMC). The experimental design involved the study of the following options: peat-based substrate without zeolite (control); substrate 95% + ZMC 5%; substrate 90% + ZMC 10%; substrate 85% + ZMC 15% of the volume. The addition of zeolite increased the survival of microplants at the stage of acclimatization. With its share in the substrate of 15%, the viability index of blackberry and tayberry microplants reaches 100%. Cultivation of cassette plants for 60 days on a substrate containing zeolite significantly increases the length of Thornfree blackberry shoots. With a zeolite content of 10%, the length of the shoots increases by 41.0%, the number of leaves – by 23.6%, in relation to the control. In the raspberry hybrid Tayberry in the best variants, the growth increased by 15.9% compared to the control. With a zeolite content of 5 and 15%, Tayberry cassette plants form 18.9% more leaves. The growth of foliage in the experimental variants was accompanied by an increase in leaf area. Mass analysis of vegetative parts of plants of Tayberry raspberry hybrid showed a significant increase in the development of the root system. The best result was observed in the variant with the addition of 10% zeolite to the substrate, the superiority over the control in wet weight was 38.9% on average. In the variants with zeolite, the separation of the substrate from the walls of the cassette cell during drying occurs much less frequently than in the control, and the formation of an air gap between them, which negatively affects the development of the root system.
