Rapid in vitro regeneration of Gerbera jamesonii (H. Bolus ex Hook. f.) from different explants
Rapid in vitro multiplication of shoots has been described using capitular sections and leaf explants in Gerbera jamesonii. Three types of basal media regimes were used including MS and two of its modified forms⎯MSI and MSA. Shoot induction was achieved on all three regimes but MSI medium supplemented with Kn (4 mg/l) and IAA (0.5 mg/l) was ideal for shoot bud initiation (8-11) from capitular s...
متن کاملRapid plant regeneration from Gerbera jamesonii Bolus callus cultures
A high frequency shoot organogenesis and plant establishment protocol has been developed for Gerbera jamesonii from ex vitro leaf derived callus. The optimal callus was developed on Murashige and Skoog (MS) basal medium supplemented with 0.4 mg L 6-benzylaminopurine (BAP), 4.0 mg L -naphthalene acetic acid (NAA) and 3% (w/v) sucrose. Two callus types differing in their structures and growth rat...
متن کاملTetranychus urticae (Acari: Tetranychidae) on Gerbera jamesonii Bolus and Hook (Asteraceae).
Gerbera (Gerbera jamesonii Bolus and Hook,) is an ornamental Asteraceae of great commercial value, and pests can affect adversely its cultivation. More than 20 species of arthropods cause economic damage on gerbera, among them the two spotted mite, Tetranychus urticae Koch, 1836 (Acari: Tetranychidae), considered a key pest for this and other ornamental plants. In this work, some life-cycle asp...
متن کاملاثر ترکیبات هورمونی مختلف بر ریزازدیادی پانزده رقم ژربرا (Gerbera jamesonii Bolus ex Hooker f.)
ژربرا یکی از مهم‌ترین گیاهان زینتی می‌باشد که به‌صورت گل بریده و گیاه گلدانی مورد استفاده قرار می‌گیرد. روش‌های معمول تکثیر کارایی تامین تقاضای جهانی برای این گیاه زینتی را ندارد. لذا عمومی‌ترین سیستم برای ازدیاد تجاری ژربرا، ریزافزایی می‌باشد. در این پژوهش، اثر تیمارهای هورمونی مختلف و رقم بر تکثیر و ریشه‌زایی ریزنمونه نوک شاخساره پانزده رقم ژربرا مورد بررسی قرار گرفت. در مرحله تکثیر از محیط ک...
متن کاملMorphological and Biochemical Responses of Gerbera (Gerbera Jamesonii L.) to Application of Silica Nanoparticles and Calcium Chelate under Hydroponic State
The purpose of this study was to investigate the response of physicochemical properties of gerbera (Gerbera Jamesonii L.) to silica nanoparticles (Nanoparticle-SiO2) and calcium chelate (Ca-Chelate) in nutrient solutions. A factorial experiment based on completely randomized design with two factors was conducted in four replicates. The first factor the concentration of Nanoparticle-SiO2 in nutr...
