Gene flow is a crucial parameter that can affect the organization of genetic diversity in plant species. It has important implications in terms of conservation of genetic resources and of gene exchanges between crop to wild relatives and within crop species complex. In the Beta vulgaris complex, hybridization between crop and wild beets in seed production areas is well documented and the role o...
abstract this study aimed at investigating the possible relationship between self-assessment in writing and self-regulation of iranian efl learners. the main purpose of the study was not only to report and inform about this relationship, but also to investigate and find practical outcomes of the incorporation of self-assessment in writing, such as improving writing skill. the research was carr...
this study was conducted to determine the effect of variable nitrogen supply on yield parameters of two sugar beet varieties, as well as on biomass allocation to different parts of sugar beet plant at safi-abad agric. res. center during 2003-4 and 2004-5. five nitrogen rates (0, 60, 120, 180 and 240 kgha-1) and two monogerm sugar beet varieties (shirin and rasol) arranged as factorial in a rand...
Agricultural insurance is one of the appropriate ways to overcome the risk in agricultural production and to increase farmers’ income security. In this study, the influence of wheat insurance, as personal-free insurance, and sugar beet insurance, as group-forcible insurance, on farmers’ risk attitudes in Fars Province were investigated as a case study. Data were collected using stratified multi...
a field experiment was conducted to study the spatial relationships between weed seed bank and population and their distribution models in sugar beet crop (beta vulgaris) in 2009 at motahari agricultural research station of karaj. sampling from seed bank before sugar beet drilling and weed population in three stages during the growing season were done using square (50*50 cm) and rectangle (25*...
The rapid population growth and the need for more agricultural production necessitate more attention to water shortage and enhancing water productivity. To assess water productivity and supply:demand ratio index in sugar beet, this experiment was carried out using SUCROS growth simulation model. Long-term climatic data and collecting questionnaires from farmers were used to assessing water prod...
BACKGROUND Obtaining dedifferentiated cells (callus) that can regenerate into whole plants is not always feasible for many plant species. Sugar beet is known to be recalcitrant for dedifferentiation and plant regeneration. These difficulties were major obstacles for obtaining transgenic sugar beets through an Agrobacterium-mediated transformation procedure. The sugar beet line 'NK-219mm-O' is a...
To evaluate the growth duration and seed yield of two different Guar ecotypes in response to planting time and plant density, a field experiment was conducted in 2016 growing season at the research field of Tarbiat Modares University, Iran. Experimantal factors were arranged as split plot-factorial in a randomized complete block design with three replications. The experimental factors included...
this research was carried out to evaluate the effects of irrigation methods and n fertilizer rates on the quantity and quality of sugar beet in ekbatan research station during 2001 and 2002. experiment was performed in split-plot with 3 replications and 15 treatments. treatments included 3 irrigation systems: sprinkler (solid set)، furrow (hydroflum) and drip (tape: 508-20-500) in main plots an...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
