Potato cultivars Katahdin (susceptible) and Rosa (resistant) were exposed to infective second-stage juveniles (J2) of Globodera rostochiensis for varying periods of time, after which root systems were washed and plants were placed in Hoagland's solution to assess J2 egression and male emergence. After transfer to liquid culture, many J2 egressed from both cultivars, but significantly more egres...
ROSA is an e-learning system, which enables the management of Learning Objects (LOs). However, since ROSA is a centralized system, it does not provide a complete integration of LOs created in local ROSAs of other institutions. This paper presents the evolution of ROSA into a peer-to-peer (P2P) system the ROSA P2P, and describes the integration process of LOs in this environment. It provides the...
An experiment was conducted to develop a suitable in vitro plant regeneration technique for Rosa hybrida L. cv. ‘Double Delight’ using nodal segments and leaf tissues as explants through direct indirect organogenesis. Aseptic were inoculated onto gelled MS medium contained various strengths of growth regulators alone combinations callus shoot induction. containing 2.0 mg/l BAP found be the most...

In many states, Japanese beetle, Popilliajaponica Newman (Coleoptera: Scarabeidae), is no longer quarantined, and management is left to professional applicators and consumers. Adult management in hybrid tea rose, Rosa L., was compared among biorational insecticides, novel imidacloprid applications (tablet, gel, and root dip), and conventional insecticides. Efficacy of biorational insecticides u...
Objective: The antiulcer activity of various extracts of Hibiscus rosa sinensis leaves was evaluated in pyloric ligation induced gastric ulcer in albino rats. Method: The leaves extracts were prepared by cold maceration process with petroleum ether, alcohol and water separately. Results: Oral administration of aqueous and alcohol extracts (200 and 400 mg/kg) of Hibiscus rosa sinensis leaves wer...
کشت میکروسپور یکی از روش های کارآمد تولید گیاهان هاپلوئید می باشد. در پژوهش حاضر، سیستم کشت میکروسپور در دو رقم تتراپلوئید رز (‘apollo’ و ‘amarosa’) مورد بررسی قرار گرفت. عواملی شامل محیط جداسازی میکروسپورها (ab و b)، محیط القای جنین زایی در میکروسپورها (at3) به همراه منابع مختلف کربوهیدرات (ساکارز، مالتوز یا گلوکز) و آمینو اسید لاکتالبومین هیدرولیزات مورد مطالعه قرار گرفتند. اثر تنش های گرسنگی...
postharvest senescence is a major factor, limiting the marketing of many species of cut flowers, including roses. considerable efforts have been devoted to developing postharvest treatments to lengthen the extend of the marketing period. the purpose of this study was to determine the most suitable nitric oxide, and thidiazuron concentrations to increase the antioxidant activity as well as prote...
