in order to compare morphophysiological traits between new and old cultivars of barley (hordeum vulgare l.) a greenhouse experiment was conducted in greenhouse condition in faculty of agriculture, ferdowsi university of mashhad in spring and summer 2011.the type of experiment was a completely randomized design with eight treatments (nosrat , youssof , fagr30 , nick) and four old cultivars inclu...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
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...
Effects of different levels of nitrogen fertilizer and cutting time of forage on grain and forage yield of barley (Hordeum vulgare L.) Karoon cultivar was studied during 1995-1996 at Ramin Agricultural Research and Educational Center, University of Shahid Chamran, Ahwas, by using a split plot design in randomized complete block with 4 replications. Main plots were assigned to five levels of N...
Although phyAphyBphyC phytochrome-null mutants in rice (Oryza sativa) have morphological changes and exhibit internode elongation, even as seedlings, it is unknown how phytochromes contribute to the control of internode elongation. A gene for 1-aminocyclopropane-1-carboxylate oxidase (ACO1), which is an ethylene biosynthesis gene contributing to internode elongation, was up-regulated in phyAphy...
Photosynthesis and wheat grain yield responses to supplemental irrigation with different amount of applied water under dryland conditions were investigated. Therefore, a two-year field experiment was conducted research farm of College of Agriculture, Shiraz University during 2004-2005. Five levels of irrigation including dryland conditions, irrigation at stem elongation, booting, flowering an...
Abstract A field experiment was carried out in one of the agricultural fields Muqdadiya region during season 2022-2023 to study role spraying with nanofertilizer called Super Micro Plus at levels (0, 1, 2 and 3) g/L as a first factor times (the beginning tillering stage, elongation maturity stage) second some growth characteristics stems yield sugarcane, variety Cp 89. The according completely ...
This study was conducted at Biology Department, Faculty of Science,Taif University, Saudi Arabia to investigate the effect of different salinity concentrations 8.6, 12.9, 17.2, 25.9, 34.5, 51.7, 86.2, 103.4 and 120.7 mM NaCl, beside control treatment (tap water) on growth parameters, leaf measurements and leaf chemical constituents of jojoba (Simmondsiachinensis (Link) Schneider). The results i...
The rate of acidification of media by Avena stem segments was studied with a titrimeter. GA(3) increased this rate by an average of 17% if supplied to the segments 90 min prior to measurement. GA(3) inhibited the rate by 15% if supplied 10 min prior to measurement. After 90 min incubation, stimulation of elongation had started; at 10 min, GA(3) had not yet started to stimulate elongation in the...
