Plants of an ecotype of Silene 6ulgaris (Caryophyllaceae) originating from a Cd-Pb-Zn mine at Plombière (Belgium) were grown on 15 polymetallic soils for a full life-cycle to investigate physiological responses which can help explain previously reported disorders in plants. The degree of regulation of the metal concentration in the young seedlings was a very reliable indicator of the subsequent...
Short-spike canarygrass (Phalaris brachystachys (Link.)) from Iranian wheat fields has developed resistance to acetyl-coenzyme A carboxylase (ACCase) inhibitors due a target-site mutation (Ile-1781-Thr). Target-site mutations may confer pleiotropic effects in weeds. In this paper, the possible effect of Ile-1781-Thr on ecological fitness during life cycles P. plants was investigated. ACCase gen...
Background and objectives: The application of growth-facilitator materials to improve germination, early establishment, and plants growth can increase the success of rangeland improvement, planting, and pasture construction projects. In addition, growth facilitators can improve the quantity and quality of vegetation cover and production in dry-farming lands by increasing the success of cultivat...
Planting pattern through changing vegetative growth and utilization of environmental resourses affects yield components and seed yield. These effects were studied in the spring of 2000 at the Agricultural Research Station, Isfahan University of Technology, using a randomized complete block design with a split plot layout and three replications. Main plots consisted of three row distances (30 cm...
High biomass crops have recently attracted significant attention as an alternative platform for the renewable production of high energy storage lipids such as triacylglycerol (TAG). While TAG typically accumulates in seeds as storage compounds fuelling subsequent germination, levels in vegetative tissues are generally low. Here, we report the accumulation of more than 15% TAG (17.7% total lipid...
Organic vegetable production has specific research and innovation requirements which are not shared by other parts of the food and farming sector. A pot experiment was conducted to investigate the interactive effects of few permitted organic inputs such as arbuscular mycorrhizal fungi, biochar, and different ratios of peat:worm casting on tomato (Solanum lycopersicum L.) growth, mycorrhizal dep...
Eastern gamagrass [Tripsacum dactyloides (L.) L.] is currently being selected for higher forage yield. A prolific variant which can produce up to 20 times the number and 3 times the weight of seeds of a normal plant was found in a wild population and is now instrumental in the breeding program. Could this prolific type spread in wild populations? Vegetative vigor of mature plants was assessed b...
supplementary irrigation is a key factor in dryland production of lentil (lens culinaris medik.). in order to study the effects of supplementary irrigation on phenological and morphological characters of three lentil (lens culinaris medik.) cultivars, a trial carried out as split block based on randomized complete block design with three replications at research field of agricultural college, f...
introduction: nitrogen is an essential element forplants and in combination withelements such as carbon, oxygen, hydrogen and sulfur results ineven more valuable materials such as amino acids, nucleic acids, alkaloids. hibiscus tea (hibiscus sabdariffa ) from malvaceaefamily is known by different names in different parts of the world. in iran it is calledthe maki tea, tea meccaorred tea.as an i...
