Coastal ecosystems are increasingly threatened by eutrophication and dystrophy. In this context, the full pattern of a bloom dominated dinoflagellate, Lepidodinium chlorophorum, was investigated high frequency monitoring buoy equipped with sensors allowing nutrients photosynthesis measurements. An increase N/P ratio affected phytoplankton physiology leading to collapse slight oxygen depletion. ...

• The timing of N fertilization needs to consider the seasonal fluctuations in nitrogen (N) uptake. These could be summarized as followes: _ during the four weeks after budbreak : N is sourced from N stored in permanent structures, _ from 2 weeks before bloom to 4 weeks after bloom: there is a major N uptake by the roots, and _ after 4 weeks post-bloom: new peaks of N uptake happen at veraison ...

The objective of this study was to investigate the effect different rates ethephon on return bloom and yield, fruit quality ‘Fuji’ apple trees. experiment performed during 2014/2015 2015/2016 growing seasons. Eighteen-year-old Fuji Standard trees grafted M.9 were sprayed with (300 mg L-1, 400 500 L-1) 30 days after full (DAFB) compared an unsprayed control. Yield components (number per tree, we...

selection and introduction of superior genotypes from native populations is one of the most common improving methods for fruit trees in the world. iran as a very important origin of apricot has a huge diversity of varieties, so a rich collection of local and imported genotypes of apricot was induced in sahand horticultural research station from 1971. nasiri 90 and other four superior varieties ...

The current study investigates the dissipation kinetics of two imidacloprid (IMI) nanoformulations (entitled: Nano-IMI and Nano-IMI/TiO2) on common bean (Phaseolus vulgaris) seeds under field conditions and compares them with 35% Suspension Concentrate (SC) commercial formulation. To do so, it sprays P. vulgaris plants at 30 and 60 g/ha within green bean stage, sampling them during the 14-day p...

Objective(s): In recent years, there has been an increasing amount of study on early diagnosis of kidney injury through sensitive and specific biomarkers. We examined the practical applicability of the urinary levels of NAG (N-acetyl-β-D-glucosaminidase), AP (alkaline phosphatase), and LDH (lactate dehydrogenase) as renal dysfunction screening biomarkers in full and pre-term newborns treated wi...
