[ 1 ] - تأثیر کم آبیاری و تنش شوری در تولید ارزن پادزهری بر برخی ویژگی‌های شیمیایی خاک
This study was conducted to determine some mineral content concentrations in soils and plants of three elevation classes (1500, 2200 and 3000m) and two phenological stages of flowering and seedling in north facing slopes of Sabalan rangelands. Soil samples from the depth of 20cm and plant samples using 1×1m plots with 10 replications were collected. After sample preparation, the concentrations ...
[ 2 ] - شاخص‌های فیزیولوژیکی کمبود آهن در درختان چنار(Plantanus orintalis L.) فضای سبز شهر اصفهان
Iron chlorosis is an important disorder of plane trees (Plantanus orintalis L.) in green space of Isfahan city. Before using reclamation methods for correcting Fe chlorosis, it is necessary to find a suitable index for evaluating plant Fe status. Therefore, activity of glutathione peroxidase (GP) enzyme and concentration of carotenoids and chlorophyll a and b pigments, as physiological indices ...
[ 3 ] - مقایسه ارقام مختلف گندم بهاره از لحاظ پاسخ به کوددهی آهن در یک خاک آهکی
This study was conducted in Rudasht Research Farm Isfahan, to evaluate tolerance to iron (Fe) deficiency of 30 spring wheat genotype, using split plots in a randomized complete block design with three replications. Main plot consisted of two Fe levels (0 and 20 kg Fe ha-1 applied as FeEDDHA at planting and beginning of vegetative growth). Grain yield increased by 14% following the application o...
[ 4 ] - پاسخ چهار دورگه ذرت به کمبود آهن و روی در محلول غذایی در شرایط کشت بدون خاک، I: رشد گیاه و ویژگی‌های فلورسانس کلروفیل برگ
The growth and fluorescence parameters of chlorophyll in four corn hybrids including two sweet (K.S.C. 403 and K.S.C. 404) and two grain hybrids (S.C. 500 and S.C. 700) were evaluated in response to Fe and Zn nutrition in a nutrient solution culture. This study was conducted in a randomized complete block design with a factorial arrangement with three replications at the Soilless Culture Resear...
[ 5 ] - ارزیابی نقش ویژگی‌های ریخت‌شناسی ریشه گیاه تریتیکاله (Triticale spp) در تولید دانه تحت شرایط کمبود آب
Plant roots, with respect to their intrinsic characteristics, have important role in both improvement and development of germplasms of drought resistant plants. This experiment was conducted to study direct and indirect effects of root morphological traits on grain yield of four triticale genotypes (three promising lines of ET-82-8, ET-82-15 and ET-79-17 along with the conventional Junillo-92...
[ 6 ] - تأثیر شوری کلرید سدیم بر الگو و سرعت توسعه ریشه گیاه ارزن پادزهری (Panicum antidotale Retz.)
Abstract Identification of growth and development pattern of plant organs, especially the roots, is important to optimal management of halophytes production. In this study, blue panic grass (Panicum antidotale Retz.) was planted in a sandy loam soil in plastic tubes and 4-leaf seedlings were exposed to different levels of irrigation water salinities including 0, 10, 20, and 30 dS/m. These sali...
