Opportunities exist for replacing reduced height (Rht) genes Rht-B1b and Rht-D1b with alternative dwarfing genes, such as the gibberellin-responsive gene Rht12, for bread wheat improvement. However, a comprehensive understanding of the effects and mode of action of Rht12 is lacking. In the present study, the effects of Rht12 were characterized by analyzing its effects on seeding vigour, seedlin...

in iran, more than 90% of raw materials including oils and oil seeds are provided through import. camelina sativa l. as an oilseed crop, belongs to brassicaceae family, has been shown in several experiments that need very little water and resistant to chilling injury than other plant oils, especially canola. this experiment was conducted at research station of campus of agriculture and natural ...

Winter wheat has a central role in ensuring the food security and welfare of 1.3 billion people in China. Extensive previous studies have concluded that winter wheat yields would decrease with higher temperatures, owing to warming-induced soil drying or shortening of phenophase. Temperature in China is predicted to increase by 1-5°C by 2100, which may greatly impact plant production and cause o...

Background and aim: The genus Satureja L. (Lamiaceae) includes 12 species of annual and perennial herbaceous plant in Iran. Satureja species have economic and medicinal importance because of their high essential oil content. In addition, they are used as culinary herbs and in the food, perfume and cosmetic industries. The aim of this study was to inve...

introduction red beans (phaseolus vulgaris l.) with 22-25 % protein and 50-60 % carbohydrates are one of the most important legumes in the world, particularly in some developing countries. it is one of the major sources of vegetable protein. with regard to increasing population and increasing the need of protein, the use of plant resources like red bean with a large amount of protein is growing...

tak-ab is a new winter bread wheat cultivar developed from evaluation of icarda-turkey-cimmyt international bread wheat germplasm to supplementary irrigation areas. study of new cultivars under supplementary irrigation in maragheh and ardebil research stations (2005-2012) showed that, tak-ab had high grain potential under supplementary irrigation conditions. based on results means of grain yiel...

     It has been reported that in different regions and sowing dates, the response of crops to past climate change is not the same, due to different rates of decrease/increase in each climatic variable at different regions and months of year. This study was aimed to assess the effect of individual versus simultaneous changes in solar radiation (S), precipitation (P) and temperature (T) on rainf...

in order to investigation of sowing date effect on yield of millet species and its impressible from duration of phonological periods and development rate, an experiment was conducted based on complete randomized block design as combine analysis in four replications at eight sowing dates (30 april, 1 jun, 31 may, 4 july, 5 august, 1 september, 2 october and 3 november) and three millet species (...

introduction the study of growth parameters such as net assimilation rate (nar), leaf area ratio (lar), relative growth rate (rgr) and leaf area duration (lad) are important for analyzing yield constraints. the growth parameters can be used to understand the crop response to environmental variables during the growing season. the aims of the present study were to 1) consider the growth indices u...

1 Wheat Research Center, Bangladesh Agricultural Research Institute, Gazipur, Bangladesh ABSTRACT. Twenty five spring wheat genotypes were evaluated for terminal heat stress tolerance in field environments in the Agro Ecological Zone-11 of Bangladesh, during 2009-2010 cropping season. The experiments were conducted at Wheat Research Centre, Bangladesh Agricultural Research Institute, using rand...
