Background: Peptic ulcer disease is a most common disease, whose incidence is increasing presently on account of demanding stressful life. Objectives: To evaluate and compare the antiulcer activity of the extracts of seed and skin of Vitis Vinifera (Grape) using two different doses (100 & 200 mg/kg). Methods: The extracts of seed and skin of Vitis Vinifera were investigated for their anti-ulcer...
application of most antibiotic growth promoters as feed additives has been banned in a lot of countries due to cross-resistance against pathogens and residues in tissues. therefore, scientists are searching for alternatives to antibiotics nowadays. medicinal plant extracts are one of the alternatives that have anti-microbial and growth promoting effect on poultry. in this paper, the benefits of...
Polyphenol oxidase (PPO) activity was investigated during rooting in cuttings from three different grape cultivars (Vitis vinifera L. cvs. Muscat, Cardinal and Perlelte), and the enzyme activity and rooting ability were compared. Rooting was observed on the Muscat and Perlelte cuttings, but not on the Cardinal cuttings. PPO activity started to increase in the early stage of the experiment, and ...
اطلاعات کمی در مورد تأثیر پیش تیمار قارچ های آربوسکولار مایکوریزا بر ریزازدیادی گیاهی وجود دارد. در پژوهش حاضر، اثرات مایه کوبی چهار رقم انگور (عسگری، خلیلی، کشمشی و شاهرودی) با سه گونه مختلف این قارچ (glomus mosseae, g. fasciculatum, g. intraradices) برجنبه های مختلف رشد و فیزیولوژی قلمه ها و نیز امکان بهبود فرایند ریزازدیادی آنها مورد ارزیابی قرار گرفت. ابتدا چهار رقم انگور تلقیح شده با مایکو...
انگور رقم شاهرودی به مدت 45 روز تحت شرایط بسته بندی در اتمسفر تعدیل یافته با چهار ترکیب گازی شامل هوای عادی (gc1)، o2 5% + co210% (gc2) ، o215%+co210% (gc3) و o260% + co2 10%(gc4) و دو نوع پوشش پلی مریک شامل پلی پروپیلن (pp) و پلی اتیلن (pe) در دمای oc1 و رطوبت نسبی 80-90% انبار شد. نمونه برداری هر 15 روز یکبار انجام شد و ویژگی های کیفی پس از 24 ساعت قرارگیری در دمای اتاق اندازه گیری شدند. نتای...
composite edible coating comprising xanthan gum (0.3%) and olive oil (0.1%) enriched with antioxidants (gallic acid 0.1%, ferulic acid 0.1% and ascorbic acid 0.1%) enhanced the postharvest storability and nutritional quality of table grapes. the quality characteristics of table grapes were monitored during storage at 10±2°c, (70–75% rh), at regular intervals of 6 days until 24 days of storage. ...
Stilbenoids, a family of polyphenols known for the complexity of their structure and for their diverse biological activities, occur with a limited but heterogeneous distribution in the plant kingdom. The most prominent stilbene containing plant family, the Vitaceae, represented by the famous wine producing grape vines Vitis vinifera L., is one of the richest sources of novel stilbenes currently...
Using conventional methods it is impossible to extract RNA as uncomplexed intact molecules from the leaves of grapevines (Vitis vinifera L.) and from a number of woody perennial species that contain high levels of reactive phenolic compounds. A procedure involving the use of high concentrations of the chaotropic agent sodium perchlorate prevents the binding of phenolic compounds to RNA during e...
Olfaction is of major importance for survival and reproduction in moths. Males possess highly specific and sensitive olfactory receptor neurones to detect female sex pheromones. However, the capacity of male moths to respond to host-plant volatiles is relatively neglected and the role that such responses could play in the sensory ecology of moths is still not fully understood. The present study...
