the time of duration of plant developmental stages could have an effect on crop yield and adaptation in a specific environment. the aim of this study was to evaluate the phenological behavior in a wide range of wheat cultivars and their relation with adaptation and potential of crop production in a specific climate (semi-arid and cold). by using a simple lattice design with three replications i...
This study was conducted to evaluate the effect of titanium dioxide and titanium oxide foliar application during two growing stage on growth and forage production of maize during 2012 growing season in the research farm of Islamic Azad University of Varamin-Pishva Branch. The experimental design was randomized complete blocks arranged in factorial with four replications. The factors were includ...
The variety of plant architectures observed in nature is predominantly determined by vegetative and reproductive branching patterns, the positioning of lateral organs, and differential stem elongation. Branches, lateral organs, and stems are the final products of the activity of meristems, groups of stem cells whose function is genetically determined and environmentally influenced. Several deca...
most of the verbal constructions of harzani dialect have got inflectional affixes. the majority of the constructions are made up vy adding a specific verbal affix to the verbal stem (infinitive without infinitive marker). only a few number of them is formed by adding a verbal affix to the past participle of the verb. there are specific rules for the formation of different verbal types. there is...
Blue light is known to induce suppression of stem elongation. To avoid the complication of blue-light-induced transformation of phytochrome we have adapted the procedure of measuring blue-light-induced suppression of stem elongation in Pisum sativum L. var Alaska grown under continuous red light. The resulting fluence-response curve for suppression of epicotyl elongation measured twenty-four ho...
Plastic stem-elongation responses to the ratio of red:far-red (R:FR) wavelengths enable plants to match their phenotype to local competitive conditions. However, elongation responses early in the life history may occur at the cost of reduced plasticity later in the life history, because elongation influences both allocation patterns and structural integrity. A common-garden experiment was perfo...
A total of 25 advanced rapeseed (Brassica napus L.) varieties were evaluated under cold weather conditions using Randomized Complete Block design (RCBD) with four replications in Dr. Nakhjavani Agricultural Research Station, 35 km North-East of Urmia the capital of West Azerbaijan province in 2000-2001. The results showed significant differences among the varieties (P ≥ 0.01) for all the pheno...
The present study was conducted in order to investigate the effect of salicylic acid on growth, yield and macro-elements absorption of fennel in split-plot as base on randomized complete block design (RCBD) with three replications in Tehran, Iran. Irrigation regime as main plot was undergone in 5 levels that included: I1: full irrigation, I2: cut off irrigation at stem elo...
Understanding the nitrogen remobilization by plant, in order to obtain cultivars with higher quality, has specific importance in plant physiology. In this experiment, a bread and a durum wheat cultivar, were treated with different rates and times of nitrogen application, by using split factorial on the basis of randomized complete block design with three replications at Shiraz region during 200...
