Abstract

In order to evaluate the effect of different levels of drought stress and PHOSPHORUS fertilizer on some PHYSIOLOGICAL traits and ESSENTIAL OIL of SWEET BASIL (Ocimum basilicum L.), a factorial experiment was carried out in completely randomized design in a greenhouse of College of Agriculture, University of Zabol, Iran in 2009. Studied factors were water deficit (drought) in 3 levels (100%, 80% and 60% field capacity) and 3 levels of PHOSPHORUS fertilizer (0, 50 and 100 kg per ha). The results showed the effect of water stress levels (p<0.01). Interactions between water stress and PHOSPHORUS fertilizer led to significant reduction (p<0.05) on leaf relative water content, but different value of PHOSPHORUS fertilizer did not cause significant difference in this trait. Percent of Shoot protein significantly affected by PHOSPHORUS fertilizer and water stress treatments protein percentage increased with increasing severity of water stress and its value was for control, mild and severe stress, equal to 1.15, 1.95 and 2.38 percent, respectively. Water stress have significant effect (p<0.01) on chlorophyll fluorescence. So that at the control, 80 and 60 percent field capacity chlorophyll fluorescence values was equal to 0.85, 0.74 and 0 /64, respectively. Amount of Chlorophyll (chlorophyll meter) in two stages 15 and 30 days after stress treatment on basil plants showed the lowest amount of chlorophyll was obtained in conditions of severe stress (60 percent field capacity) at 30 days after the water stress amount that it‘s be equal to 6.17. Totally it seems SWEET BASIL at WATER DEFICIT STRESS conditions, with high production of proline and carbohydrate execute drought tolerance mechanism, but this conditions lead to decrease of chlorophyll and increase of chlorophyll fluorescence.
