ABSTRACT Effect of Chloride Sodium on Chlorophyll Fluorescence, Plant Proline Content and Flowers Production of Three Ornamental Species. Three ornamental species (Zinnia elegans, Tagetes patula and Petunia hybrida) were used to test sodium chloride effect on chlorophyll fluorescence, plant proline content and flowers production. Three treatments were used in this trial: 0, 2 and 4 g of Nacl.l-1 of irrigation water. The results showed that chlorophyll fluorescence was not affected by sodium chloride treatment but plant proline content increased and flowers production decreased as NaCl doses increase.
