Abstract Water stress is one of the limiting factors of plant growth. In order to investigate the effect of chitosan and nano-chitosan on Nigella sativa L. under drought stress, a split plot experiment based on randomized complete block design was conducted in research Field of Islamic Azad University Arak Branch in 2016. The main plots consisted of spraying with chitosan, nano-chitosan and water as control and the sub plots consisted of cultivars Arak, Azerbaijan, Semirom, Yasuj and Torbat-e-Heydariyeh. Irrigation was performed regularly from the beginning of planting until flowering stage and then stopped and spraying was achieved. After 80% emergence of floret, plots were sampled and number of secondary branches, capsules per plant, plant height, 1000 seed weight and oil percentage were evaluated. Percentages of oil and fatty acids were measured by gas chromatography.Experimental results were showed that drought stress reduced the components of black cumin yield but improved qualitative factors such as oil and fatty acids percentage. The highest and lowest seed oil content was in Azarbaijan (28.76%) and Semirom (26.39%), respectively. Yasuj can be considered as a drought tolerant cultivar due to its high content of capsules, 1000-grain weight and weight/m2. The effect of nano-chitosan in moderating stress-induced effects was better than chitosan. Azerbaijan and Semirom cultivars had the highest amount of oleic acid (Omega 9), Yasuj cultivar had the highest amount of linoleic acid (Omega 6) and Torbat Heydariyeh and Arak cultivars had the highest amount of linoleic acid (Omega 3).

In this split plot study, the morphological and phytochemical changes of Iranian Salvia (Salvia mirzayanii L.) under drought stress and cerium oxide nanoparticle treatment in a randomized complete block design with three replications were investigated. The main plot included drought stress at 4 levels of 25, 50, 75 and 100 (control) percentage of the field capacity (FC).  The sub-plot was foliar spray of Cerium oxide nanoparticle at five levels of non-consumption (control), 125, 250, 500 and 1000 ml/l. Essential oils were extracted from the organs using water distillation method and the compounds were separated and identified using GC/MS. The results showed that the interaction effect of conditions without drought stress × 1000 ml of nanocerium oxide compared to the control treatment had the greatest effect on increasing plant height (35%), root length (22%), root dry weight (14.9%), essential oil (19%), chlorophyll a (32%), chlorophyll b (31%) and catalase (16%). In addition, drought stress at the level of 25% in 125 ml nano cerium oxide decreased plant dry weight (12%), root length (13%), root dry weight (19%), essential oil percentage (10%), and chlorophyll a (14%). Based on the GS/MS results, decane compound (19.53%) in the condition without drought stress, the compounds of spatholeol (35.86%), docane (18.4%), butanic acid (19.8%) and linalool (25.03%) under condition of stress dryness of 50% field capacity and octane (13.76%) were included. Therefore, the concentration of 1000 mg/liter of cerium nanooxide had the greatest effect on improving the morphophysiological characteristics of Salvia. However, in the condition of 50% field capacity, the secondary compounds of spatholeol, dodecane, butanic acid and linalool were the highest, but in the condition of 75% of the field capacity, the highest amount belonged to the secondary compounds of octane, trimethyl and hexylisovalerate.  Manuscript profile
