چکیده

حساس‌‌ترین دورة زندگی هر گیاه به تنش شوری، مرحلة جوانه‌زنی است. بذر بسیاری از گونه­های گیاهی با قرارگیری در معرض آب، لایه­ای ژله‌مانند به نام لعاب (موسیلاژ) تولید می­کنند. هدف از این پژوهش بررسی تأثیر لعاب در تحمل شوری بالنگو شهری بود. بذرهای بالنگو دارای لعاب است که در درمان برخی اختلال‌های عصبی، کبدی و بیماری­های کلیوی به­کار می­روند. بدین منظور آزمایشی به­صورت فاکتوریل در قالب طرح کاملاً تصادفی در چهار تکرار در سال 1392 در آزمایشگاه گیاه‌شناسی دانشکدة منابع طبیعی دانشگاه یزد انجام شد.عامل‌ها شامل تنش شوری (0، 5، 10، 15 و 20 دسی­زیمنس بر متر کلریدسدیم) و نوع بذر (با لعاب و بدون لعاب) در نظر گرفته شدند. نتایج نشان داد که تأثیر تنش شوری بر همة صفات معنی­دار بود. با افزایش شدت شوری جوانه­زنی و رشد آغازین هر دو نوع بذر کاهش معنی­داری یافت و بیشترین و کمترین میزان هر یک از صفات به‌ترتیب متعلق به شاهد و به شوری 20 دسی­زیمنس بر متر بودند. همچنین بذرهای لعاب‌دار در مقایسه با بدون لعاب درصد جوانه­زنی و درازای ساقه­­چة بیشتری داشتند. به‌طور کلی نتایج نشان­دهندة نقش مثبت لعاب در بهبود جوانه­زنی بذر در شرایط تنش شوری است. با این‌حال میزان تأثیر این ماده بسته به نوع گیاه و حجم لعاب موجود در بذر می­تواند متفاوت باشد.

چکیده [English]

Seed germination is the most sensitive growth stages of the plant to salinity stress. Seeds of many species produce a jelly-like layer called mucilage upon exposure to water. The purpose of this study was to determine the role of mucilage in increasing salinity tolerance of Lallemantia ibrica. Seeds of this plantcontain mucilage that can be used to treat some diseases such as neurological, liver and kidney disorders. Thus, a factorial experiment was conducted arranged in completely randomized design with four replications at Botany Laboratory of Yazd University in 2013. Salinity stresses (0, 5, 10, 15 and 20 dS m-1) and seed type (with and without mucilage) were considered as first and second factors, respectively. Results showed that all traits were significantly affected by salinity stress. Germination and early growth of both seeds type decreased with increasing salinity stress. The highest and lowest seed germination rates were obtained in control and salinity level of 20 dS/m, respectively. Seeds with mucilage had higher seed germination and shoot length compared to seeds without mucilage. Overall, results indicated the positive role of mucilage in improving germination of L. ibrica seeds under salinity stress. However, the ability of mucilage in improving seed germination depends on plant species and amount of seeds mucilage.
