topping stage of tobacco is a key time for development of agriculture measures to promote the quality of leaves. in order to investigating influence of topping timing and suckericide content on tobacco leaf, a factorial experiment on the basis of rcb design with 3 replications was conducted in 2011 at the tobacco research farm of isfahan. treatments were including topping time (t1: topping at e...

detopping in some plants reduces vegetative growth and increases transporting of photosynthate materials to specific sinks such as seeds. to study the effects of detopping removal and plant density on yield and yield components of faba bean (vicia faba l.), an experiment was carried out as a factorial arrangement based on a randomized complete block design with three replications at farm resear...

Appropriate flowering timing is crucial for plant reproductive success. The florigen, FLOWERING LOCUS T (FT), interacts with 14-3-3 proteins and the bZIP transcription factor FD, functioning at core nodes in multiple flowering pathways. There are two FT homologues, FT1 and FT2, in Brachypodium distachyon. Here we show that FT2 undergoes age-dependent alternative splicing (AS), resulting in two ...

in order to study effects of competitive weeds (sinapis arvensis, hordeum spp., secale montanum and agrostemma githago) on morphological traits, yield and harvest index of winter rapeseed (brassica napus l.) cultivars a factorial experiment was conducted in islamic azad university of tabriz, during 2007-2008. experimental factors were weeds controlling times included weeding in rosette (5-7 lea...

Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is one of the most important herbivores in a broad range of cultivated plants, including cotton, cereals, vegetables, and fruit crops in China. In this manuscript, we report on a 6-year long study in which (adult) A. lucorum abundance was recorded on 174 plant species from 39 families from early July to mid-September. Through the study period pe...

Stage II breast cancer is further subdivided into stages IIA and IIB. Patients classified as having stage IIA breast cancer include those with T0-1, N1, and T2, N0 disease. Stage IIB breast cancer includes patients with T2, N1, and T3, N0 disease. Therefore, this patient population is more heterogeneous than the populations with stage 0 and stage I disease. The pretreatment evaluation and type ...

Background: Thymus daenensis is on e of the endemic aromatic species in Iran that its essential oil is used in food and pharmaceutical industries. Objective: In this study, the effects of plant growth stages and distillation methods on essential oil content and thymol percentage of this species were evaluated. Methods: The aerial parts of Th. daenensis were collected in three stages of plan...
