In present experiment callus induction and plantlet regeneration of four sesame varieties (Oltan, Yekta, Varamin and Single Branch Naz) have been considered in different environments with different hormone combinations. In order to evaluate callus induction, after surface sterilization of seeds, diploid embryos were isolated and cultured on related media enriched with 1.5, 2, 2.5 and 3 mg l-1 2...
Fritillaria meleagris is a horticulturally and medicinally valuable bulbous plant that requires period of low temperatures for proper growth flowering. Since conventional methods propagation are ineffective very slow, tissue culture techniques offer an integrated approach to mass production this geophyte. In study, we investigated the effects various auxin–cytokinin combinations on different mo...
Momordica dioica Roxb. (Spine Gourd) (Cucurbitaceae) is an important vegetable with high food and medicinal value. Maintaining tuber quality in field conditions as well its conservation during storage is difficult. Micropropagation may help to overcome these problems to a great extent. As there is limited information on the above mentioned aspects is not available. Therefore, the present study ...
The effect of different culture media with different growth regulator and nitrate/ammonium ratios on split garlic shoots was studied to obtain an optimized micropropagation protocol. Three basal media: MS, BDS and BLM (i.e. BDS modi®ed to obtain a nitrate:ammonium ratio of 35 mM:8 mM) combined with two concentrations of NAA (0.5 or 5 mM) and BAP (1 or 10 mM) were evaluated in three Colorado gar...
Objective: To develop in vitro callus induction in nodal segments of Decalepis hamiltonii and investigate the antioxidant potential of the callus. Methods: In this study, nodal segments of Decalepis were cultured on Murashige and Skoog (MS) medium supplimented with various concentration of 2,4-D for callus induction and later subcultured on various concentration of NAA and BAP. The antioxidant ...
به منظور بررسی جنین زایی بدنی در گونه های اکالیپتوس، نوع ریز نمونه (بساک، محور زیرلپه، لپه ها، پهنک برگ و دمبرگ)، نوع محیط کشت (MS, B5)، انواع هورمونها از قبیل اکسینها (NAA, 2, 4-D) و سایتوکینینها (BAP, TDZ) به علاوه شرایط محیطی (نور، تاریکی و درجه حرارت) مورد آزمایش قرار گرفتند. کالوس جنین زای حاصل از ریز نمونه محور زیرلپه در گونه Eucalyptus camaldulensis در محیط کشت اولیه که عبارت بود از محیط...
In vitro propagation of rose (Rosa indica) as well as rose breeding is a valuable economic enterprise and has received highest importance globally including Indian subcontinent. The development of new cultivars for commerce is faced with new challenges. In vitro micropropagation protocols of varieties of roses have been established but very few reports on the clonal propagation of local cultiva...
این تحقیق به منظور ایجاد لاین های پرمحصول و متحمل به شوری از رقم با عملکرد بالا ولی حساس به شوری (والفجر) همچنین ایجاد لاین های با تحمل گسترده و بالا به شوری از ارقام با تحمل نسبی به شوری (افضل ‘ آشار و آریگاشار) با استفاده از تنوع سوماکلونی انجام گردید. در این بررسی غلظتهای مختلفی از نمک کلرورسدیم (3‘ 4‘ 5‘ 6‘ 8 و 10 گرم در لیتر) و ترکیبی از املاح کلرورسدیم و کلرید کلسیم ( به ترتیب 5/6 و 5/3 گ...
زعفران گیاهی تریپلوئید است که منبع متابولیت های ثانویه و یکی از مهمترین محصولات اقتصادی و دارویی ایران می باشد. در این مطالعه تکثیر درون شیشه ای زعفران با استفاده از دو روش مستقیم و غیرمستقیم مورد بررسی قرارگرفت. قطعات بنه که به عنوان ریزنمونه مورد استفاده قرار گرفتند، پس از ضدعفونی به محیط کشت ms با غلظت های مختلف هورمونی مربوط به باززایی مستقیم و غیر مستقیم منتقل شدند. تیمار کلرید جیوه 15/0 %...
An efficient clonal propagation procedure for six rice varieties cultivated in Argentina was developed by using shoot tip cultures, and the genetic stability of the micropropagated plants was verified by isozyme analysis. One week old seedlings obtained on MS medium were sectioned and subcultured on MS medium (0.75% agar) supplemented with different combination and concentrations of cytokinins ...
