Utjecaj boje sjemene ljuske na upijanje vode, klijanje sjemena i nicanje graha

Common bean (Phaseolus vulgaris L.) is the most widespread legume in Croatia and the production is based on landraces of great morphological diversity. Cultivars morphologically differ most in the seed coat colour, which affects water uptake, seed germination and sprouting. In this study, 50 seeds from each white-coloured landraces 'Biser' (small-seeded) and 'Bijeli' (large-seeded) and dark-coloured landraces 'Kornjača' (smallseeded) and 'Trešnjevac' (large- seeded) were used for three stages of the experiment. Namely, 200 seeds of Croatian common bean landraces were used for the water uptake experiment, 200 seeds for seed germination, and 200 for sprouting. It was found that the white- coloured seeds uptake more water than the dark- coloured seeds of similar mass at the same time. Also, white-coloured seeds release more electrolytes what leads to greater damage within the seeds. It was also found that white-coloured and smaller seeds germinate faster than dark- coloured large seeds and that small-seeded cultivars sprouted faster than large-seeded.
