Evaluation of drought stress level in Sargent's cherry ( Rehder) using photosynthesis and chlorophyll fluorescence parameters and proline content analysis.

Sargent's cherry trees (Rehder) are widely planted as an ornamental, climate change-sensing species. This study investigated changes in the soil moisture content, fresh weight, photosynthesis and chlorophyll fluorescence properties, and the chlorophyll and proline content of four-year-old seedlings after 30 days of drought stress. In the trees subjected to drought stress treatment, soil moisture content decreased, and the fresh weight of the aboveground part of the plant decreased.
