frequency of somaclonal variation in embryogenic calli and plants of olea europaea l cv.kroneiki derived from somatic embryogenesis were examined by randomly amplified polymorphic dna (rapd) analysis. radicle and cotyledon (proximal part) of mature zygotic embryo were cultured in omc medium supplemented with iba (5 mgl-1) and 2-ip (0.5 mgl-1). somatic embryogenesis was induced in calli of radic...
Date palm (Phoenix dactylifera L.) is propagated traditionally through offshoots or suckers, which usually appear at or below the ground level surrounding the stem base. However, there are many problems associated with this system. Offshoots are produced in limited number and vegetative propagation through them is slow, laborious, time consuming and expensive. The present study was conducted to...
For ex vitro propagation, seeds of P.pubescens were treated with different concentrations of gibberellic acid (GA3) and germination of seeds was tested both in plastic pots as well as by direct sowing in the nursery beds. Maximum seed germination was achieved when treated with 200 mgL(-1) (w/v) GA3. For in vitro propagation, an exposure of nodal explants from in vitro raised seedlings to 0.2 mg...

The present study was carried out to evaluate the effects of light and plant growth regulators on callus induction and explant browning in date palm cultivar, Estameran in in vitro condition. The explants were pretreated by an antioxidant combination (100 mgl-1 citric acid and 150 mgl-1 ascorbic acid) for 3 days in 5 °C. Then, the leaf explants were cultured in Murashige and Skoog medium (MS)...
Frequency of somaclonal variation in embryogenic calli and plants of Olea europaea L cv.Kroneiki derived from somatic embryogenesis were examined by randomly amplified polymorphic DNA (RAPD) analysis. Radicle and cotyledon (proximal part) of mature zygotic embryo were cultured in OMc medium supplemented with IBA (5 mgL-1) and 2-ip (0.5 mgL-1). Somatic embryogenesis was induced in calli of radic...
یونجه یک گیاه دگرگرده‌افشان است، به‌طوری‌که نگهداری و افزونش مواد گیاهی انتخاب‌شده در برنامه‌های اصلاحی از راه بذر امکان‌پذیر نیست. افزونش رویشی گیاهان انتخاب‌شده از راه قلمه، افزونش سریع و قابل‌اعتماد همسانه (کلون)های یونجه را امکان‌پذیر می‌کند. در این پژوهش ریشه‌زایی قلمه‌های سه بوم‌جور (اکوتیپ) نیک‌شهری، همدانی و سکوئل را پس از قرار گرفتن در سطوح مختلف محلول‌های تنظیم‌کنندۀ رشد اکسین، ایندو...
Salvia leriifolia is a medicinal plant from Lamiaceae family native to Khorasan and Semnan Provinaces. This plant has medicinal properties such as antinociceptive, anti-inflammatory, antidiabetic, antimicrobial and Antioxidant which all have been confirmed by researchers. In this research, callus induction was established for production of phenolic acids. For this purpose, the leaf explants wer...
The physico-chemical characteristics of Chambal river water in National Chambal sanctuary (Madhya Pradesh) have been studied. The stretch of Chambal river contained in the National Chambal sanctuary (located at 25 degrees 23'-26 degrees 52'N, 76 degrees 28'-79 degrees 15'E) is extending up to 600 km downstream from Kota (Rajasthan) to the confluence of the Chambal with Yamuna river (Etawah). Th...
Cucumis melo L. is one of the most economically important horticultural crops worldwide. However, low plant regeneration frequency of this plant during genetic transformation is the major hurdle for applying biotechnological approaches. Hence, this study aimed to evaluate the effect of 6-benzyladenine (BA), cefotaxime (CTX), kanamycin (KAN), and indole-3-acetic acid (IAA) on the regenerati...
