Prunus avium L. Seedling emergence after drying or moisturizing of seeds to 15 levels of water content (1.6− 29.0%), untreated (–LN) and treated (+LN) with liquid nitrogen for 24 h. Tukey test, the values marked with the same letter are not significantly different at P < 0.05, provenance Bieszczady Mts. (SE Poland).* In inverted commas because seedling emergence after thawing from LN was seriously lower even within this range (9.0− 16.9%) as compared with the control (nonfrozen) seeds. Regardless, this was the most favorable range of water content for seeds frozen in LN, determined on the basis of seedling emergence (Fig. 3) and germination (Fig. 2).
