Seasonal variation (e.g. temperature and photoperiod) between growing seasons might affectinulin content and inulin yield of Jerusalem artichoke. However, there is limited information ongenotypic response to seasons for inulin content and inulin yield. The objective of this studywas to investigate the variability in genotypic response to seasons for inulin content and inulinyield of Jerusalem a...
in order to study the weed populations in wheat, under different crop rotations an experiment was carried out at agricultural research station of jolgeh rokh, iran. during growing season this project was done in five years, based on randomized complete bloch design with three replications, on crop rotations included: wheat monoculture for the whole period (wwwww), wheat- wheat- wheat- canola- w...
Increasing grain yield is the most important goal in any breeding program. Since yield is a complex trait and involves several quantitative components with low inheritance, its direct evaluation is not usually sufficient and therefore it is suggested that its components be investigated instead. The objective of this study was grouping 60 inbred lines along with four check cultivars of wheat fro...
An experiment was conducted at Rasht Rice Research Institute, in 2001 to study trait relationships and to determine the direct and indirect effects of different characteristics on grain yield of rice (Orgza sativa L.). A 9x2 factorial experiment in complete randomized block design with 3 replications was used. The two factors were 9 cultivars, namely: Hashemi, Ali Kazemi, Binam, Sepeedroud, Nem...
Extended Abstract Introduction and Objective: Due to the very high diversity among the genotypes of quinoa (Chenopodium quinoa), it has shown a very high adaptability and stability in different climates. Therefore, this experiment was performed to investigate the morphological and genetic diversity of 14 quinoa genotypes and compare them with the control genotype of the region (Titicaca). Ma...
in order to study the effect of different nitrogen fertilizer rates and source-sink limitation treatments on yield and yield component of contrast rice (oryza sativa l.) cultivars, a field experiment was carried out in the rice research institute of iran-deputy of mazandaran (amol) during 2006. a split split experiment in the basis of randomized complete block design with 3 replications and 3 f...
Microbes may maximize the number of daughter cells per time or per amount of nutrients consumed. These two strategies correspond, respectively, to the use of enzyme-efficient or substrate-efficient metabolic pathways. In reality, fast growth is often associated with wasteful, yield-inefficient metabolism, and a general thermodynamic trade-off between growth rate and biomass yield has been propo...
in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...
Broomrape weeds (Orobanche and Phelipanche spp.) are root holoparasites that feed off a wide range of important crops. Among them, Orobanche crenata attacks legumes complicating their inclusion in cropping systems along the Mediterranean area and West Asia. The detrimental effect of broomrape parasitism in crop yield can reach up to 100% depending on infection severity and the broomrape-crop as...
