Abstract

Drought stress is one of the most important abiotic stresses that affects plant growth and development. In recent years, due to low precipitation and drought conditions, studying the effects of low water stress on plants performance have gained significance. Basil (Ocimum basilicum L.) belongs to Lamiaceae family which has many medicinal properties and is also being used as fresh edible vegetable. Two basil cultivars (green and purple) were grown in pots and were subjected to two water regimes of 100% (control) and 25% (drought stress) field capacity respectively. Handy PEA instrument was used to measure leaves chlorophyll fluorescence. Results showed that under drought stress the photosynthetic electron transport efficiency of green and purple basil cultivars were reduced by 57.73 and 47.11% respectively, as compared with their controls. Investigating the chlorophyll-a fluorescence also revealed that the activities of water photolysis complex, electron transport to QA acceptor and also the electron transport from the mid electron transport chain to photo system I were reduced under drought stress. With respect to electron transport efficiency in the middle of electron transport chain from b6f complex to photo system I, purple basil performed better than green basil and as a result had higher tolerance to drought stress.
