Kaplan-Meier estimator - Opis:
- The deep dormancy of the Prunus species seeds is caused by the presence of germination inhibi- tors, mainly abscisic acid (ABA) – in the endocarp, the seed coat and endosperm, and in the embryo. As a consequence, the removal of the endocarp, the seed coat together with the endosperm increases the num- ber of germinated seeds. The effect of different treatments of seeds of three peach cultivars – ‘Madison’, ‘Elberta’ and ‘Rakoniewicka’, and of three apricot cultivars – M II‑42, ‘Bella’ and ‘Somo’, were assessed in terms of seed germination and the growth of obtained young seedlings. Seed treatments involved different duration of stratification period at 5°C and removing endocarp, seed coat with endosperm and the part of cotyledons of the embryo. The best seed/embryo germination, about 96% for the peach cultivars and practically 100% for the apricot cultivars, was obtained by stratifying seeds for 90 days and then removing the seed coat together with the endosperm and subjecting the extracted embryos to a temperature of 20°C. The seedlings obtained from the seeds treated this way have shown good growth. Using these treatments, it was possible to obtain a larger number of apricot and peach seedlings, and thus increase the breeding efficiency of these species.
