within communicative, interactive, and learner-centered framework of language teaching and learning, students need to learn four skills of listening, speaking, reading, and writing for their educational success. but of all the language skills, reading enjoys a paramount significance in so many second or foreign language academic contexts. in spite of its importance, language learners still have...
Economically, rapeseed is one of the most important crops in the world. Over the past decades, rapeseed research has been focused on improving biotechnological methods to facilitate breeding. The effectiveness of these methods depends on efficient tissue culture techniques. The aim of the present study was to establish an efficient protocol for regeneration of rapeseed. It was conducted in thre...
Abstract To study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. Analysis of variance showed considerable variation among cultivars. Water stress reduced all of the studied morphological characteristics, espe...
Plant growth regulators (PGRs) are used to prevent reduction in rapeseed grain yield under limited moisture conditions. A field experiment was conducted to investigate the effect of paclobutrazol (0, 50, 100, 150 and 200 mg L-1) on canopy surface temperature and some quantitative and qualitative characteristics of two rapeseed cultivars (Okapi and Natalie) under full irrigation and late season ...
Soil salinity is a serious threat to agriculture sustainability worldwide. Salt tolerance at the seedling stage is crucial for plant establishment and high yield in saline soils; however, little information is available on rapeseed (Brassica napus L.) salt tolerance. We evaluated salt tolerance in different rapeseed accessions and conducted a genome-wide association study (GWAS) to identify sal...
This experiment was conducted as factorial split plot in randomized complete block design with three replications for two years (2015-2016 and 2016-2017) in Karaj region. Irrigation includes regular irrigation (irrigation after 80 mm evaporation from Class A evaporation pan) and irrigation-off from the silique stage onwards in the main plots and planting date including the 5th of October and th...
In order to investigate the relationships between major agronomy traits and grain yield in rapeseed, two apetalous flowers (Hylite201) and petalled (Hyola401) rapeseed cultivars were planted in three plant densities and two planting patterns was carried out in a split plot-factorial design based on randomized complete block design with three replications at Rice Research Institute of Iran at Ra...
This study was designed to evaluate the role of growth regulator trinexapac and fungicides on growth, yield, and quality of winter rapeseed (Brassica napus L.). The experiment was conducted simultaneously at different locations in Germany using two cultivars of rapeseed. Five different fungicides belonging to the triazole and strobilurin groups, as well as a growth regulator trinexapac, were te...
abstract the first purpose of this study was to investigate the effect of consciousness-raising (c-r) activities on learning grammatical structures (simple present tense in this case) by iranian guidance school efl learners. the second one was to investigate the effect of gender on learning the simple present tense through c-r activities and tasks. finally, this study aimed to investigate the ...
