title: Impact of negative temperatures on the state of the photosynthetic apparatus of evergreen species of &lt;i&gt;Osmanthus&lt;/i&gt; Lour. genus
abstract: The results of studies of photosynthetic processes in annual leaves of two species of the genus Osmanthus - Osmanthus x fortunei and O. fragrans in the cold period on the Southern coast of the Crimea and under the controlled action of negative temperatures are presented. It is shown that the main parameters of chlorophyll fluorescence induction (CFI) in annual leaves of O. x fortunei was relatively more stable during the winter months compared to O. fragrans . The effect of temperature -8,0°C fo
