Abstract:

In order to observe the temperature stress resistance of 4 Cerasus cultivars in north China, including Cerasus× kanzakura ‘Kawazu-zakura’, Cerasus× kanzakura ‘Oh-kanzakura’, Cerasus× kanzakura ‘Tariyo-zakura’ and Cerasus× kanzakura ‘Rubescens’, the contents of chlorophyll and proline in leaves under high temperature stress, the contents of SOD and MDA in branches under low temperature stress were measured respectively. Combined with field observation, the data were analyzed. The results showed that, among the 4 Cerasus cultivars, the temperature stress resistance ability of Cerasus× kanzakura ‘Kawazu-zakura’ was high, that of Cerasus× kanzakura ‘Oh-kanzakura’ was low. The results can provide reference for the introduction of series Cerasus cultivars in north China.

Key words: temperature stress resistance, physiological index, Cerasus× kanzakura ‘Kawazu-zakura’, Cerasus× kanzakura ‘Oh-kanzakura’, Cerasus× kanzakura ‘Tariyo-zakura’, Cerasus× kanzakura ‘Rubescens’
