Abstract
Endive (Cichorium endivia L.) is a vegetable species whose needs for seed quantity increase each year due to the growing number of hobby gardeners. Furthermore, in the last few years, it has been observed in control laboratories for seed quality that endive, regardless of its variety, has low germination energy and seed germination. The aim of this study is to examine the germination energy and seed germination of endive applying various methods used in the examination of vegetable species. The study was conducted in the laboratory for quality control of agricultural reproductive material at Križevci College of Agriculture. Energy and seed germination were tested by a four-treatment paper filter method. The first two treatments were comprised of wetting the substrate with distilled water and 0,2% KNO3, while the other two treatments were a combination of both, along with a prior pre-cooling treatment. The highest seed germination and germination energy was evidenced in samples using pretreatment pre-cooling and distilled water, while samples that were treated with a 0,2% KNO3 wetting method, as prescribed by the Ordinance of sampling methods and seed quality testing (OG 99/08) showed significantly lower energy and seed germination. Based on the results of the research, it was found that the best method for testing germination energy and seed germination was the paper filter method with wetting of the substrate with distilled water and applying precooling as a pre-treatment.
