ABSTRACT
Background: Arbuscular mycorrhizal fungi [AMF] have the potential to optimize the rhizospheric soil characteristics considerably thereby affecting plant growth
Objectives:The aim is to investigate the effects of fungi inoculation [Glomus intraradices] on morphological, physiological and phytochemical traits of Rosemary [Rosemarinus officinalis L.] under salt stress
Methods: A factorial experiment was conducted on the basis of randomized complete blocks design in three replications at the Institute of Medicinal Plants in the Academic Center for Education, Culture and Research [ACECR]. The mycorrihzal fungi in two levels [inoculation and non-inoculation] and saline conditions in five levels [EC of 0, 2, 4, 6 and 8 dS.m[-1]] were the two studied factors. The essential oil content and its components were measured with Clevenger-type apparatus and GC/Mass and GC
Results: The results showed that the interaction effect of fungi inoculation and salinity was significant [P
Conclusion: The phytochemical and morpho-physiological traits of rosemary were improved due to inoculation of mycorrhizal fungi under saline conditions
ABSTRACT
Background: Summer savory [Satureja hortensis L.] is one of the most important medicinal and spice plants cultivated in many parts of the world. Objective: A greenhouse experiment was conducted to study the effects of FeSO4 and citric acid application on the morphological traits and essential oil content and its component, gammaterpinene in S. hortensis. Methods: FeSO4 in four levels [0, 3, 4 and 5 g L-1] and citric acid in four levels [0, 4, 6 and 8 mM] through foliar application were considered as two studied factors in this factorial experiment. Results: The results showed that the treatments of FeSO4, and interaction of FeSO4 and citric acid had a significant effect [p<0.01] on the all studied traits, whereas citric acid treatments only had significant effect on the essential oil content [p<0.01] and plant height [p<0.05]. FeSO4 and its interaction with citric acid significantly increased these traits. The optimum level of FeSO4 fertilizer on this plant was 3 and 4 g L-1 and for citric acid was 6 and 8 mM which increased the essential oil content and its component, gamma-terpinene compared to control plants. Conclusion: Foliar application of citric acid plus FeSO4 had the capability to alter the relative percentages of the essential oil content. In general, foliar application of FeSO4 with citric acid had synergistic effect on essential oil content, its component gamma-terpinene and agromorphological traits of S. hortensis
ABSTRACT
Diabetes mellitus is a syndrome, initially characterized by a loss of glucose homeostasis resulting from defects in Insulin secretion, insulin action both is resulting in impaired metabolism of glucose and other energy yielding fuels as lipids and protein. Several medicinal herbs have been described with hypoglycemic effects. These include: Allium Sativum, Trigonella Foenum, Marus nigra, Ocimum Sanctum, and Astragalus Ovinus. The main purpose of the present study was to determine the effect of Achillea Wilhelmsii C. Koch on blood glucose levels of diabetic rats induced by stereptozotocine [STZ]. In this experimental research, forty-eight male Wistar rats were divided into two groups: non-diabetic [normal] and STZ-induced diabetic mice. Each group was further divided into four groups: control [induced by normal saline] and treatment received 100, 200 and 300 mg/kg for one month. The blood glucose level was measured and Data were analyzed by t- test and ANOVA. At the end of first month, significant decrease was observed in blood glucose level in diabetic rats which received 100 mg/kg [p<0/001], 200 mg/kg [p<0/01], 300 mg/kg [p<0/001] of aqueous alcoholic extract of Achillea Wilhelmsii c. Koch in comparison with control groups. The extract had not have any significant effects on the blood glucose level of normal groups except in those which received 300mg/kg of the extract. The results of this study showed that aqueous-alcoholic extract of Achillea Wilhelmsii C. Koch have a significant effect on reducing the blood glucose level of diabetic rats
