The timing of flowering is coordinated by a web of gene regulatory networks that integrates developmental and environmental cues in plants. Light and temperature are two major environmental determinants that regulate flowering time. Although prolonged treatment with low nonfreezing temperatures accelerates flowering by stable repression of FLOWERING LOCUS C (FLC), repeated brief cold treatments...

abstract in order to evaluate the effect of different nitrogen application methods on yield and yield components of winter wheat, a field experiment with split plot arrangement in completely randomized blocks design with four replicates was conducted in 2006. basal dressing in three levels (1- with no basal dressing, 2- strip and 3- distributing nitrogen fertilizer) as main plot and top dressin...

Nutrient deficiency negatively affects the yield and quality of citrus fruit. The present experiment was carried out to investigate improvement in fruit juice Kinnow (Citrus reticulata L.) by foliar application nano-biochar suspension (NBS). a farmer’s orchard with history low yield, using randomized complete block design. Four NBS treatments, i.e., 0% (control), 1, 3, 5%, were applied through ...

to evaluate of drought stress and foliar application of zinc and iron on two annual medics species, experimental field was carried out with split factorial based on randomized complete block design in three replication with treatments of foliar application (controlled, fe, zn and iron+ zinc) and cutoff irrigation from (50% flowering , lower pod maturity,10 days before starting of flowering and ...

The chemical composition of the essential oils of flower at the pre-flowering, full-flowering and post-flowering stage of A. annua was analyzed by GC and GC/MS and sixty-two components were identified. The main compounds in the pre-flowering oil were β-myrcene (37.71%), 1, 8-cineole (16.11%) and camphor (14.97%). The full-flowering oil contained predominantly caryophyllene (19.4%), germacrene D...

The purpose of the present work was to evaluate both the antioxidant response system and oxidative stress in leaves from bitter gourd (Momordica charantia L) subjected to NaCl, UV-B and water stresses at three different stages of plant growth: pre-flowering, flowering and post-flowering. Except for peroxidase (POX), all enzyme activities including superoxide dismutase (SOD), catalase (CAT), pol...

In order to investigate the effect of deficit irrigation and chemical fertilizers on yield some physiological traits quinoa an experiment was conducted in 2019 as split plot based a randomized complete block design two locations (Mashhad Neishabour). Irrigation included, I0: full irrigation, I1: no at emergence stage, I2: stem elongation I3: flowering I4: seed setting stage. Fertilizer treatmen...

BACKGROUND In patients with traumatic brain injury, hypothermia can reduce intracranial hypertension. The benefit of hypothermia on functional outcome is unclear. METHODS We randomly assigned adults with an intracranial pressure of more than 20 mm Hg despite stage 1 treatments (including mechanical ventilation and sedation management) to standard care (control group) or hypothermia (32 to 35°...

  This experiment was carried out in Bandargah Station in Bushehr province. Peneaus semisulcatus larvae were fed on Spirulina platensis as supplementation microalgae. In order to use spirulina platensis in this study, we have to produce biomass and dry production of this microalga. Determination of length and survival rate of Peneaus semisulcatus larvae was carried out as the objective of the s...
