The effect of substrate on the quality of strawberry plants produced by soilless method was determined in a vegetation chamber. ‘Elsanta’ and ‘Honeoye’ cultivars were rooted in a substrate mixture of peat with pine bark (1:1 v/v), in coconut fibre, in a mixture of brown coal with disintegrated rockwool (2:1 v/v) and in rockwool blocks.

Rockwool was found to be the most useful substrate for the production of strawberry plants. Plants obtained in this substrate had the greatest crown diameters and the highest number of leaves. Statistical analysis showed that substrate also had a significant effect on fresh weight of the whole plant and on dry matter content of the root system. The average diameter of the crown ranged between 10.0 and 18.0 mm. Plants grown in rockwool showed the greatest average number of leaves (11.87 pcs). Plants grown in coconut fibre and in the mixture of brown coal with disintegrated rockwool had the least number of leaves (10.5 pcs). Fresh weight of the whole plants and dry matter content of root systems were the highest when strawberry plants were rooted in rockwool.
