27 different populations of Triticum boeoticum were gathered from west and North West of Iran for their grouping using morphological traits. All populations were assessed in farm based on completely random design with three replications in 1393. The measured traits include stem length with spike, spike length with and without awn, awn length, flag leaf length, the woolly leaves, peduncle length...
To identify genes involved in meristem function we have designed a screen for temperature-sensitive mutations that cause a conditional arrest of early shoot development in Arabidopsis. We describe the characterization of three mutations, arrested development (add) 1, 2 and 3. At the restrictive temperature the add1 and add2 mutations disrupt apical meristem function as assayed by leaf initiatio...
Diffusion of CO2 inside leaves is generally regarded to be from the substomatal cavities to the assimilating tissues, i.e. in the vertical direction of the leaf blades. However, lateral gas diffusion within intercellular air spaces may be much more effective than hitherto considered. In a previous work it was demonstrated that, when 'clamp-on' leaf chambers are used, leaf internal 'CO2 leakage'...
In order to study the correlation of agronomic, morphologic and physiologic traits and their effects on grain yield of rice genotypes in two environments (favorable irrigation and water stress), 49 genotypes were evaluated using a completely randomized block design with 3 replications in two experimental conditions. All practices and conditions were the same for the two experiments with the exc...
general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...
Topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. In order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of RCB design with 3 replications was conducted in 2011 at the Tobacco Research Farm of Isfahan. Treatments were including topping time (T1: t...
In order to evaluate the effect of urban wastewater and different fertilizer sources on macro and micro nutrients' concentration and shoot dry weight of sugar beet, a field experiment was arranged as a split plot in RCBD design with three replications at Research Station of Shahrekord University in 2013. The main factors included irrigation with urban wastewater at 2-4 leaf stage and 8-12 leaf ...
abstract this thesis includes five chapter : the first chapter assign to establish fuzzy mathematics requirement and introduction of liner programming in thesis. the second chapter we introduce a multilevel linear programming problems. the third chapter we proposed interactive fuzzy programming which consists of two phases , the study termination conditions of algorithm we show a satisfac...
Diagnosis of crop growth and nutrient status is critical for prediction of agriculture yield and quality at Growth stage. Two experiments, one in 2006 and one in 2007 were conducted to find out spr-wheat canopy and leaf spectral characters nondestructively measurement, and for assessing spring wheat growth status non-destructively at the Experimental Farm (30o53′N, 104o25′E) of Lanzhou Universi...
