Influence of seedlings quality on consumer parts of selected species of cabbages

Abstract

The aim of this work was to evaluate the influence of seedling preparation technology (seedling flats with cell size of 20 ml, 40 ml and seedlings pulled from patches) and of seedling age at the time of planting (development stages of 3–4 true leaves and 5–6 true leaves) to the qualitative characteristics of seedling of selected cabbage species: white cabbage (Brassica oleracea L. convar. capitata (L.) Alef. var. alba DC.) – Aros, Avak, Midor; cauliflower (Brassica oleracea L. convar. botrytis (L.) Alef. var. botrytis L.) – Beta, Delta, Rober and savoy cabbage (Brassica oleracea L. convar. capitata (L.) Alef. var. sabauda L.) – Vega, Versus. The diameter and weight of rosaces, resp. heads, was evaluated in the harvested production. After splitting the harvested crop into several groups, the percentage of non-standard portion of the yield was determined. The use of older seedlings (5–6 true leaves) for the white and savoy cabbage planting had a positive influence to both average yield and the harvest earliness. On the other hand, for the cauliflower conclusively better average crop of rosaces and earlier harvests were achieved with younger seedling transplanting (3–4 true leaves). Seedling flats proved to be the most suitable way of seedling preplantation; no differences were found between the characteristics of products cultivated from the seedling flats with 20 ml and 40 ml cell volumes. In average, smaller amount of non-standard harvest plant parts was, gained with the transplanting from larger seedling flats (40 ml cell volume).
