Frost resistance of species and hybrids of the genus Lavandula L.
Abstract
The article presents data of frost resistance in various genotypes of narrow-leaved lavender and its hybrids. Frost resistance was a valuated with freezing method under controlled conditions by the level the degree of damage of plant shoot tissues in temperature range from -16 °C to -25 °C. The results showed that at a temperature of -16 °C, damage to all studied species and hybrids was minimal. Minor damage of bark and wood tissues was observed at -18 °C and -20 °C. It was determined that the critical temperature leading to the freezing of the above-ground parts of the plants is -25 °C. The most frost-resistant genotype of lavandin was identified, showing only minor damage at the critical temperature. It was also established that lavandin No. 11 and the Prima cultivar of narrow-leaved lavender can serve as sources of frost resistance in targeted breeding programs.
