چکیده

کاربرد گیاهان بومی و دارویی در منظر شهری، با نیاز آبی کم و نیاز به مراقبت کمتر و همچنین گونه­هایی با پتانسیل و ارزش زینتی بالا، در حال افزایش می­باشد. در این تحقیق نیز قابلیت کشت گونه­های آویشن Thymus kotschyanus، T. sepyllum، T. fedtschenkoi، T. vulgaris،T. daenensis  و T. pubescence  در فضای سبز طی 2 سال مورد ارزیابی قرار گرفت. نتایج نشان داد که گونه­های Thymus kotschyanus، T. sepyllum و T. fedtschenkoi بیشترین پذیرش و گونه­های T. pubescence و T. daenensis کمترین پذیرش را از لحاظ زیبایی در مرحله رشد رویشی و زایشی، در بین مردم داشتند. همچنین، گونه T. kotschyanus به­دلیل گلدهی زودهنگام در بهار، طول دوره گلدهی بیشتری نسبت به سایر گونه­ها، به‌خصوص گونه­های دیرگل T. sepyllum و T. daenensis داشت. بیشترین سطح پوشش، تعداد گل‌آذین و تعداد گل در گل­آذین نیز در گونه­های T. sepyllum وT. kotschyanus مشاهده شد. گونه‌های T. sepyllum و T. vulgaris طویل‌ترین گل­آذین­ها را به خود اختصاص دادند؛ ولی اندازه گل­های این گونه­ها خیلی کوچک­تر از سایرین بود. بزرگ‌ترین گل و قطر گل­آذین در گونه­های T. daenensis و T. pubescence مشاهده شد. در کل، گونه‌های مورد مطالعه دارای صفات ارزشمند جهت معرفی به فضای­سبز هستند؛ ولی گونه­های T. kotschyanus و T. sepyllum، به­ترتیب مناسب­ترین گونه­ها جهت معرفی به‌عنوان گیاهان پوششی در فضای­سبز هستند.

چکیده [English]

The possibility of using six thyme species (Thymus sepyllum, T. kotschyanus, T. vulgaris, T. daenensis, T. pubescence and T. fedtschenkoi) as a ground cover plant in landscape were evaluated in a two year period. Results showed that in aesthetics point of view during vegetative and reproductive stages, Thymus sepyllum, T. kotschyanus, and T. fedtschenkoi had the highest ranks, while T. pubescence and T. daenensis has got the lowest ranks. Because of early flowering under favorable weather conditions in spring T. kotschyanus had the longest flowering period in comparison to other late flowering species, i.e. T. sepyllum, and T. vulgaris. The highest area coverage, inflorescence number and flower number per inflorescence were also recorded in T. sepyllum and T. kotschyanus. In comparison to other species, T. sepyllum and T. vulgaris had the longest inflorescence, but flower size of these species was smaller than the others, whereas the largest inflorescence diameter and flower size were shown in T. daenensis and T. pubescence. In general, results showed that all studied species have valuable ornamental potential, but T. kotschyanus and T. sepyllum are the most suitable species as a ground cover plant in landscape.
