Abstract

The seeds of vegetable species intended for hobby gardeners are mostly imported, of standard category and packed in small packages. Importers that carry out repacking of seeds ae obliged to have the seeds tested for germination capacity after repacking. They withdraw the unsold quantity of seed at the end of season and put it back on the market in the next two to three seasons without controlling germination capacity of seeds, leading to poor germination capacity or lack of germination capacity of the seeds sold on the market. Research objective was to test germination capacity of 24 vegetable species on samples of seed batches stored in air-conditioned storage and on samples of the same batches that were on the market for two vegetation seasons and compare the germination capacity with the values obtained after the import of seeds. Research results indicate that germination capacity of the seeds of leaf celery (Apium graveolens var. secalinum L.), knobcelery (Apium graveolens L.), leafparsley (Petroselium crispumssp. crispum L.), leek (Allium porrum L.), broadbean (Vicia faba L.), pepper (Capsicum annuum L.) andspinach (Spinacia oleracea L.) is primarily influenced by plant species, where as storage conditions significantly influenced germination capacity of cabbage (Brassica oleracea L.), broccoli (Brassica oleracea L. var. italica), lettuce (Lactuca sativa L.) and red beet (Beta vulgaris L. var. conditiva). Out of 24 seed batches of vegetable species sampled in the storage of the processor (importer) 46% of them failed to meet there quirements for prescribed minimal germination capacity after 20 months, where as out of the same batches sampled in the storage room of the laboratory (controlled conditions) 29% of samples did not have sufficient germination capacity. By means of ensuring optimal storage conditions and control of gerimantion capacityit is possible to positive lyaffect the quality of vegetable seeds on the market.
