Assessment of seed quality of different cabbage lots during aging

Rapeseed is a major oilseed crop that has various uses in the food, feed, and industrial sectors. The first condition for successful production and achieving high yields is to provide high-quality seeds, which, in addition to high seed vitality, also implies good seedling protection. The goal is to ensure an optimal number of plants per hectare, which is also a basic prerequisite for achieving high yields. Quality seed treatment has proven to be the best solution for plant protection in the initial stages of development. The seeds were treated with fungicides with the a.i. carboxin + thiram and fluopicolide + fluoxastrobin, as well as an insecticide with a.i. flupyradifuron, and the control was untreated seed. Treatments had a great influence on germination energy, seed germination, number of abnormal seedlings, length and weight of seedlings. The fungicidal fluopicolide + fluoxastrobin treatment had the greatest positive effect on most of the tested parameters, while the carboxin + thiram + flupyradifuron treatment had the greatest negative effect on the seed germination parameter.

The aim of the research was to evaluate the effect of year and seed hybrids on the most significant indicators of the seed quality of cucumber. Testing the quality of seeds of three different hybrids of cucumber: Centauro F1, Edona F1 and Solatio F1 was carried out during a five-year period (2018 - 2022). Analysis of germination energy, seed germination, abnormal seedlings and dead seeds cucumber showed highly significant differences (r<0.01) under the influence of individual factors of the year (Y) and hybrid seed (H), as well as their interaction (Y × H). The seed germination of the examined hybrids by year slowly decreases and is the lowest at 94% in the fifth year (2022). The strongest positive correlation was established between germination energy and seed germination (r = 0.95635, p<0.001) and between abnormal seedlings and dead seeds (r = 0.92301, p<0.001). As expected, a negative and highly significant (p < 0.001) correlation was established between germination energy and: abnormal seedlings (r = -0.94535) and dead seeds (r = -0.93255). Likewise, a strongest negative (p < 0.001) correlation was found between seed germination and: abnormal seedlings (r = - 0.97497) and dead seeds (r = -0.98545). The obtained results indicate that the germination energy and seed germination of highly hybrid conventional cucumber seeds decreases significantly after the third year of aging, but only in the case of the Edona F1 hybrid.

The aim of the research was to evaluate the influence of the hybrid and the medium for germination testing on indicators of pepper seed quality. The obtained results should provide an answer as to whether the application of different growing media for testing seed germination can lead to discrepancies between test results in quality indicators for hybrid seeds. The seed quality of three pepper hybrids: KG 2025 F1, KG 2129 F1 and KG 2032 F1 was tested on two growing media (filter paper and substrate). Statistical analysis of germination energy, total germination, diseased seedlings and dead seeds showed highly significant differences (r<0.01) under the influence of the hybrid factor. The growing media factor also had a highly significant effect on all examined quality indicators , except for total germination. A significantly lower number of abnormal and diseased seedlings was found on the filter paper compared to the substrate. A highly negative significant correlation (r =-0.90951, p≤0.001) was recorded only between total germination and diseased seedlings. The obtained results indicate that the application of different media for testing the germination of hybrid pepper seeds can lead to inconsistencies in the obtained values for all evaluated quality indicators.
