Abstract

Gerbera(Gerbera jamesonii) from the family of Asteraceae is regarded as one of the best cut flowers in the world. Despite of the publicity of Gerbera’s cut flowers, they have a short postharvest life. The objective of the present study was to study the replacement feasibility and the comparison of thymol (isolated from zataria), and essential oils of peppermint and rosemary (200, 400 and 600 mg l-1) with silver nitrate (200 mg l-1) in vase solution of gerbera cut flowers in order to increase vase life and some quality traits. The recorded traits were vase life, carotenoid, solution uptake, relative fresh weight, flower diameter, total dissolved solids and pH. The experiment was laid on a factorial arrangement based on a randomized complete block design with three replications. Means comparison revealed that the highest vase life was related to the treatment of silver nitrate, however, flowers treated with thymol (200 mg l-1) in comparison with other natural treatments, had the highest vase life and did not show significant differences with silver nitrate. The treatment of peppermint essential oil (200 mg l-1) resulted in the highest carotenoid level. The highest relative fresh weight and solution uptake were obtained for the thymol treatment (200 mg l-1). The highest amount of total soluble solids and flower diameter were obtained in the silver nitrate treatment. The lowest pH was obtained from the treatment of 600 mg l-1 peppermint essential oil. In total, it can be concluded that thymol and the essential oils of peppermint and rosemary can be used in vase solution of gerbera cut flowers. Further research using other natural compounds is required to find out the appropriate compound and also concentrations in order to help the environment conservation and improve human health in addition to increase the vase life of cut flowers.

بررسی جایگزینی ترکیبات طبیعی به جای نیترات نقره در محلول نگهدارنده گل شاخه بریده ژربرا

Abstract [فارسی]

ژربرا (Gerbera jamesonii) یکی از بهتـرین گـل‌هـای بریـده جهـان محسوب می‌شود. با وجود محبوبیت گل بریده ژربرا، ایـن گـل دارای عمر پس از برداشت کوتاهی است. هدف از انجام پژوهش حاضر، بررسی قابلیت جایگزینی و مقایسه تیمول (مستخرج از آویشن شیرازی)، اسانس‌های نعناع فلفلی و رزماری (200، 400 و 600 میلی‌گرم در لیتر) با نیترات نقره (200 میلی‌گرم در لیتر) در محلول گلجایی گل شاخه بریده ژربرا به منظور افزایش عمر گلجایی و برخی صفات کیفی گل بود. صفات اندازه‌گیری شده شامل عمر گلجایی، کاروتنوئید، جذب محلول، وزن تر نسبی، قطر گل، مواد جامد محلول و pH محلول بود. این آزمایش در قالب طرح کاملا تصادفی و با آرایش فاکتوریل با سه تکرار انجام شد. نتایج نشان دادند که بیشترین عمر گلجایی مربوط به تیمار نیترات نقره بود. در عین حال گل‌های تیمارشده با تیمول (200 میلی‌گرم در لیتر) در مقایسه با سایر تیمار‌های طبیعی، بیشترین عمر گلجایی را داشتند و اختلاف معنی‌داری با نیترات نقره نشان ندادند. تیمار اسانس نعناع فلفلی (200 میلی‌گرم در لیتر) بیشترین میزان کاروتنوئید را داشت. بیشترین جذب محلول و وزن تر نسبی در تیمار 200 میلی گرم در لیتر تیمول به دست آمد. بیشترین میزان مواد جامد محلول و قطر گل در تیمار نیترات نقره حاصل شد. کمترین pH محلول در تیمار نعناع فلفلی (600 میلی‌گرم در لیتر) حاصل شد. به طور کلی نتایج نشان داد که تیمول و اسانس‌های نعناع فلفلی و رزماری قابلیت استفاده در محلول گلجایی گل شاخه بریده ژربرا را دارند که با تحقیقات بیشتر و استفاده از برخی ترکیبات طبیعی دیگر می‌توان به غلظت‌های مناسبی جهت تیمار گل­های بریده دست یافت تا بتوان علاوه بر افزایش طول عمر گل­های بریده به حفظ محیط زیست و سلامت انسان نیز کمک کرد.
