ABSTRACT
Background: Ocimum basilicum L. belongs to the Lamiaceae family. Its essential oil is antibacterial and anti-fungi it is used an appetizer and counterfeit. Methanol spraying as a source of providing carbon for C3 plant, can increase the plant yield, and its rate of ripping it can decrease the effect of water stress
Objective: The present study was conducted to investigate the effect of foliar application of methanol and nano-iron chelated fertilizer on phytochemical and morph physiological characteristics of basil
Methods: In this research, the factorial experiment in a randomized complete blocks design with 20 treatments and 3 replications was carried out. The treatments of this experiment were consisted of five levels of Methanol [0, 10, 20, 30, and 40 %] and four levels of Nano-iron chelate [0, 0.5, 1, 1.5 g/L] fertilizer
Results: The study showed that spraying methanol with 20% volume along with 1 g/L of nanoiron chelated increased dry matter and oil yield and also increased methyl-cahvicol and Caryophyllene in Basil. Results showed that activity of Glutathione peroxidase enzyme was increased with increasing the percentage of bio simulative methanol, while activity of polyphenol oxidase was decreased
Conclusion: Nano-iron chelated increased the activity of these enzymes. It can be concluded that higher densities of bio-simulative methanol and Nano-iron chelated increased essential oil, methylcahvicol and some other affective enzymes which decrease induced environmental stresses. Although, higher densities of them would decrease biosynthesis of neral and neryl formate
ABSTRACT
Background: Salvia multicaulis Vahl. a medicinal plant belonging to the Lamiaceae family, has an extensive application in native and traditional medicine
Objective: This research was conducted to investigate diversity of morphophysiological traits and content of essential oil, phenol and flavonoid of Salvia multicaulis ecotypes in different districts of Hamedan province, Iran
Methods: In this study, 11 ecotypes of Salvia multicaulis were collected from different districts of Hamedan Province at the full flowering stage in spring 2016 and were evaluated for their morphophysiological and phytochemical characteristics. The classification of ecotypes was done on the basis of phytochemical and morphophysiological traits by cluster analysis and correlations among quantitative traits was also conducted by Pearson method
Results: Result showed that the essential oil content had positive significant correlation with plant height, inflorescence length, dry matter of flowering branche and essential oil yield. Also there was a positive significant correlation between essential oil yield with receptacle length, flower fresh and dry matter and plant dry matter. The heighes dry weight of flowering branch and flower was related to ecotypes of Lashkardar and west of Hamedan, respectively. The maximum plant dry weight was belong to Yelfan ecotype. The most essential oil content was related to Lashkardar and west of Hamedan ecotypes. Also, the highest content of phenol and flavonoid related to Vehnan ecotype. According to the cluster analysis, 11 ecotypes were divided into two groups
Conclusion: The evaluation of morphophysiological and phytochemical traits showed that there was a considerable variation among different ecotypes of Salvia multicaulis in respect of morphophysiological and phytochemical characteristics
