The article presents a comparative analysis of the water-holding ability of leaves (WAL) and its connection with the freezing of the shoots of apricot seedlings of various ecological and geographical origins. A non-linear relationship was found between the WAL of the leaves of apricot seedlings and the freezing of the shoots. It was revealed that seedlings with shoot damage to the average level, WAL are higher (12-15% water content in leaves after 24 hours) than those with slightly submerged (0.8-6%). In severely freezing genotypes (freezing 60-100%), on the contrary, is lower than winter-hardy. The correlation before the peak was 0.79 *, after the peak -0.98 *, significant at the 0.05 significance level. |
