| چکیده مقدمه: گونه Stachys schtschegleevii Sosn. ex Grossh از تیره Lamiaceae بومی ایران است. در پژوهش حاضر تاثیر شرایط محیطی برشاخص‌های رشد و عملکرد ترکیب‌های اسانس این گونه در ارتفاعات مختلف کوه کیامکی در استان آذربایجان شرقی مورد بررسی قرار گرفت. روش ها: پس از بازدید میدانی، منطقه مورد مطالعه به سه طبقه ارتفاعی تفسیم شد. در هر طبقه سه ترانسکت به طول 100 متر در جهت شیب درنظر گرفته شد و روی هر یک تعداد 5 قطعه(پلات) برداشت شد. در هر پلات صفات مورفولوژیکی این گونه اندازه‌گیری شد. سرشاخه های گل دار با سه تکرار از هر طبقه جمع آوری شد و پس از اسانس گیری، ترکیب های تشکیل دهنده اسانس آنها به کمک دستگاه GC و GC-MS شناسایی شد. همچنین، در هر طبقه به طور تصادفی سه نمونه خاک از عمق 30-0 سانتی متر از مجاورت این گونه برداشت شد و در آزمایشگاه برخی از خصوصیات فیزیکوشیمیایی آنها تعیین شد. برای تعیین ارتباط صفات رویشی و مواد موثره با عوامل محیطی از تحلیل همبستگی و تجزیه مولفه های اصلی استفاده شد. نتایج و بحث: تجزیه واریانس صفات عملکردی نشان داد که ارتفاع، دمای سالانه، اسیدیته، ماده آلی، نیتروژن و بافت خاک در مقایسه با سایر پارامترها بیشترین تاثیر را در تغییرات این صفات داشتند. در میان صفات عملکردی، قطر تاج پوشش، فاصله بین گره ها، وزن برگ، آلفا-پینن، بتا-پینن، بتا-فلاندرن و جرماکرنD بیشترین همبستگی را با عوامل محیطی داشتند. واژگان کلیدی: ترکیب های اسانس، صفات مورفولوژیک، گرادیان ارتفاعی، گونه انحصاری | ||

| چکیده [English] | ||
| Introduction: Stachys schtschegleevii Sosn. ex Grossh is from the Lamiaceae family endemic to Iran. In the present study, the effect of environmental conditions on the performance of vegetative traits and essential oil compounds of this species was investigated at different altitudes of Kiamaki mountain in East Azerbaijan province. Methods: After the field visit, the study area was divided into three altitude zones. In each zone, three transects of 100 meters length were considered in the slope direction and 5 plots were taken on each. Morphological traits of this species were measured in each plot. Flowering branches were collected with three replicates from each zone and after essential oil extraction, the compounds of their essential oil were identified with the help of GC and GC/MS. Also, in each zone, three soil samples were randomly taken from a depth of 0-30 cm from the vicinity of this species and some of their physicochemical characteristics were determined in the laboratory. Correlation analysis and principal component analysis were used to determine the relationship between vegetative traits and effective substances with environmental factors. Results and discussion: Variance analysis of functional traits showed that altitude, annual temperature, acidity, organic matter, nitrogen and soil texture compared to other parameters had the greatest effect on the changes of these traits. Among the functional traits, canopy diameter, distance between nodes, leaf weight, alpha-pinene, beta-pinene, beta-flandrene, and germacrene D had the highest correlation with environmental factors. | ||
