We localized the tissues and cells that contribute to scent biosynthesis in scented and non-scented Rosa x hybrida cultivars as part of a detailed cytological analysis of the rose petal. Adaxial petal epidermal cells have a typical conical, papillate shape whereas abaxial petal epidermal cells are flat. Using two different techniques, solid/liquid phase extraction and headspace collection of vo...
A computer controlled semiclosed net CO(2) exchange measurement system, employing an infrared gas analyzer and mass flow controllers to inject pure CO(2) at preset rates, has been developed for measuring whole plant net CO(2) exchange and net C gain in a controlled environment (i.e. CO(2), light, and temperature). Data for tomato (Lycoperscicon esculentum cv Campbell 19 VF) and rose (Rosa hybri...
The use of reclaimed wastewater in agriculture can be a solution for regions with water shortages or low rainfall periods; besides fulfilling the crop's water needs, it would also promote the recycle of nutrients. However, care should be taken regarding soil salinization, especially in closed environments such as greenhouses for the cultivation of ornamental plants. The domestic effluents are r...
Due to the beneficial effects of silicon (Si) on ornamental plants, the aim of this study was to investigate the effect of different sources and concentrations of Si on some characteristics of Rose (Rosa hybrida cv. Beverly Watson). This research was conducted in 2015 in one of the greenhouses of Parks and Landscape Organization of Urmia and in Research Laboratories of Horticultural Science Dep...
Nowadays, various training systems are utilized to grow greenhouse roses. Some of the training systems permit high canopy light penetration and hence increase canopy photosynthesis rate. The aim of this investigation was to evaluate the response of arching and traditional training systems to shading (0 (no shading/control), 25, 50 and 65%) and their effects on marketing quality of cut roses (...
به منظور بررسی اثر سطوح مختلف ایندول بوتیریک اسید و نوع پایه در تکثیر گل رز به روش قلمه – پیوند، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی با 3 تکرار و ده نمونه در هر واحد انجام شد. تیمارهای مورد نظر شامل 11 سطح ایندول بوتیریک اسید (0، 25،50،250،500،1000،1500،2000،3000،4000 و 5000 میلی‌گرم در لیتر) و سه نوع پایهL. Rosa canina، R. indica var. major و R. multiflora L. بود. بر...
In order to investigate the effect of form of nitrogen (N) [ammonium (NH4) and nitrate (NO3)] and calcium (Ca) levels of nutrition solution on quantitative and qualitative yield of cut rose flower (Rosa hybrida L.), cv. Vendentta, in soilless culture condition, an experiment was conducted in greenhouse of the National Ornamental Plants Research Station of Mahallat. The experiment was factorial,...
Many efforts have been taken to increase the vase-life of cut flowers by using different methods and materials. In this research, the effect of applying citric acid and salicylic acid at pre-harvest stage on vase-life of rose (Rosa hybrida L. cv. Avalanch) was investigated. The factorial experiment was carried out as a randomized complete blocks design. Three levels of citric acid concentration...
به‌منظور مطالعه ی تأثیر سطوح مختلف پتاسیم و کلسیم بر رشد، غلظت عناصر غذایی و عملکرد گل رز در شرایط آب‌کشت، آزمایشی در سال 1386 به مدت یک سال در گلخانه ی مرکز تحقیقات کشاورزی صفی‌آباد دزفول انجام شد. آزمایش به‌صورت فاکتوریل در قالب طرح بلوک‌های کامل تصادفی با دو عامل غلظت پتاسیم و کلسیم در محلول غذایی با چهار تکرار روی گل رز رقم وندتا اجرا شد. پتاسیم شامل سه سطح 0/1، 0/5 و 0/10 میلی‌مولار در لیت...
Haploidy method through androgensis is highly important in breeding of many plants. However, this method has not been successful in rose breeding, so far. In this research the responses of two rose species (Rosa damascena Mill. and Rosa hybrida) to anther culture were investigated by using some thermal and chemical pre-treatments. Results showed that the anthers cultured in early to mid-uninucl...
