effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Absence of Epistasis for Grain Yield in Elite Maize Hybrids
ABSTRACT Measures of epistasis in maize hybrids have been estimated by (i) triple-test crosses, (ii) making comparisons Certain maize (Zea mays L.) inbred lines are more successful than of single, three-way, and double cross hybrids, or (iii) others in forming elite hybrids. This study was conducted to determine measuring variance components (Hallauer and Miwhether epistatic interactions play a...
متن کاملEvaluation of yield relationships and yield components in maize hybrids using multivariate and graphical methods in Karaj region
Extended Abstract Introduction and Objective: Selection of desirable hybrids compared to other maize hybrids (Zea mays L.) is one of the methods used to achieve high grain yield in maize. Also, the most important morphological features affecting grain yield can be used in the selection and introduction of genotypes. Material and Methods: This study was conducted to investigate the relationshi...
متن کاملanalysis of correlation coefficients between grain yield and yield components in cowpea genotypes under normal and drought stress conditions
in order to deliberate correlation coefficient between grain yield and yield components among 31 cowpea genotypes under normal irrigation (non-stress) and drought stress (water withholidng after flowering stage until maturity) an experiment was performed in a randomized complete block design (rcbd) with three replications at research field of university of tehran located at karaj during 2011-20...
متن کاملThe determination of plant density on dry matter accumulation, grain yield and yield components of four maize hybrids
The effects of plant density on dry matter accumulation, grain yield and yield components of four maize hybrids were evaluated. The experimental design was split plot format based on a randomized complete block with three replications. The study was conducted of Islamic Azad University of Dezful (Iran) farming research station in 2010. The main factors were 4 levels of hybrids (Ks.c704, Ks.c700...
متن کاملCorrelations among Grain Yield and Yield Attributes in Maize Hybrids at Various Nitrogen Levels
Three maize hybrids (Baber, Pioneer 30P45 and Syngenta 6621) were compared for yield and yield components and correlations were worked out among the yield parameters at various nitrogen levels in an experiment conducted at Agricultural University, Peshawar, Pakistan during summer 2009. The experiment was laid out in randomized complete blocks with split plot arrangement having three replication...
