Sažetak
The current study aims to evaluate the effect of fruit size of service tree (Sorbus domestica L.) on physio- morphological properties of seeds and the seed germination process. The fruit samples varying in sizes divided on the basis of weight as small (5-10 g), medium (11-15 g) and large (16-20 g) were collected from the area of Vukomeričke gorice (45°34′45″N 16°00′11″E), Zagrebačka County, Croatia. In all fruits, significant positive and very high correlation were found between the length and width of fruit (r = 0.92). There was a negative and significant correlation found between the fruit weight and the fruit shape index (r = -0.47). The number of filled seeds in fruit was significantly higher in large fruits (2.62 seeds). Seeds from large fruit had significantly greater length of radicle (3.89 mm) after 120 days of stratification at 3°C. The mean germination time of seeds from all fruits averaged 107 days. The seeds with highest weight significantly reduced rate of moisture absorption. After stratification the seeds of large fruit had the highest germination percentage (83.7%). The findings obtained will likely impact the propagation of this plant in future using seeds obtained from large fruits as it showed highest germination rate.
