چکیده مقاله :
Gerbera cut flowers is one of the important and popular cut flowers in the world that regardless of increasing production of this plant in Iran, the duration of its life is short due to rapid wilting petals and bending neck of flower. To increase vase life of gerbera cut flowers cv. ‘Alain Ducasse’, the essences of Eucalyptus and Rosa damascena, the combination of these two essences at a concentration of 200 mg L-1 with 4% sucrose and only 4% sucrose were used as treatment and distilled water was used as control treatment. In current study, the characters of vase life, wet weight, total soluble solids, solution uptake and bent neck were examined. Maximum and minimum of vase life were achieved in Eucalyptus essence treatment (12.33 days) and control (7 days), respectively. Although, Rosa damascena essence and its combination with Eucalyptus essence also increased the vase life. The maximum fresh weight and solution uptake was obtained treated with Eucalyptus oil. The maximum fresh weight and absorption of solution were obtained in treatment with Eucalyptus essence. The maximum amount of soluble solids was obtained in the treatment of sucrose. In addition, control treatment has the maximum bent neck. The overall results showed that the use of Eucalyptus and Rosa damascena essence in combination with sucrose can be used as a preservative solution of gerbera cut flowers.
گل شاخه بریده ژربرا یکی ازگل‌های مهم در دنیا می‌باشد که علی‌رغم افزایش تولید این گیاه در کشور ایران، دوام عمر آن به دلیل پژمردگی سریع گلبرگ‌ها و خمیدگی گردن گل، کم است. به‌منظور افزایش عمر گلجایی گل بریده ژربرا (رقم آلین داکاز) از اسانس‌های گیاهان اکالیپتوس و گل محمدی و ترکیب این دو اسانس در غلظت 200 میلی‌گرم در لیتر به همراه ساکارز 4 درصد و از ساکارز 4 درصد به‌تنهایی واز آب مقطر نیز به‌عنوان تیمار شاهد استفاده شد. در این آزمایش صفات عمر گلجایی، وزن تر، مواد جامد محلول، جذب محلول و خمیدگی ساقه مورد بررسی قرار گرفت. بیشترین و کمترین عمر گلجایی به ترتیب در تیمار اسانس اکالیپتوس و شاهد حاصل شد. البته اسانس گل محمدی و ترکیب آن با اسانس اکالیپتوس نیز عمر گلجایی را افزایش دادند. بیشترین وزن تر و جذب محلول در تیمار اسانس اکالیپتوس بدست آمد. بیشترین قطر ساقه در تیمارهای اسانس گل محمدی و ساکارز مشاهده شد و بیشترین میزان مواد جامد محلول در تیمار ساکارز حاصل شد. همچنین تیمار شاهد بیشترین خمیدگی ساقه را داشت. به‌طور کلی نتایج نشان داد که استفاده از اسانس اکالیپتوس و گل محمدی در ترکیب با ساکارز می‌تواند به‌عنوان محلول نگهدارنده گل بریده ژربرا به‌کاربرده شود.
