Stress due to waterlogging is considered an abiotic factor that negatively affects crop production, which, together with the excessive fertilization of crops, reduces cost-effectiveness and generates need create sustainable alternatives economically environmentally. The effect inoculation Azospirillum brasilense on physiology Raphanus sativus var. Crimson Giant subjected waterlogging, was evalu...

Polycyclic aromatic hydrocarbons (PAHs) are known to exhibit photoinduced toxicity to organisms, especially in the presence of ultraviolet irradiation. Oxidation is the most common photochemical reaction of anthracene (ANT) and ANT derivatives. Quinones, hydroxy-quinones, diols, and aldehydes are the resultant products. Different ANT photoproducts have different impact on biological organisms. ...

The study of chlorophyll fluorescence (CF) parameters i.e.: Fo, Fm, Fv/Fm, Y, qP, qN, F’o, F’m was conducted in two strawberry cultivars ‘Honeoye’ and ‘Teresa’. Measurements of their values were done twice: in an early autumn and late spring. Fluorescence of five dark-adapted mature leaves derived from each cultivar was measured in the laboratory at room temperature with the use of a portable p...

This study was conducted in order to the effect of different concentrations lead pollution on photosynthetic characteristics and growth Miscanthus floridulus, reveal its adaptability stress. The differences gas exchange parameters, chlorophyll fluorescence pigment two floridulus populations, one population from Boluo an uncontaminated site, another Dabaoshan, a mine were compared studied throug...

To study the effects of long-term and short-term high temperature stress recovery on physiological functions appearance quality chrysanthemums, a controlled experiment with chrysanthemums was conducted. The treatments were 25 °C for 3 days (T1D3), 9 (T1D9), 41 (T2D3) 41°C (T2D9). results indicated that there is no significant difference between T1D3 T1D9 groups. Conversely, total chlorophyll ...

to study the effects of two irrigation regimes and application of barley residue, zeolite and superabsorbent polymer on forage yield and some physiological traits of maize and sorghum, an experiment was conducted over two years in kerman, iran. a randomized complete block design arranged in a factorial split was used with three replications. two irrigation regimes of normal irrigation and water...

The effects of water deficit modelling by polyethylene glycol (PEG), metal nanoparticles (NPs) and their combined action on status, chlorophyll fluorescence pigments composition in the leaves three drought tolerant wheat genotypes – Triticum aestivum L. (Trypilska Favorytka cultivars) dicoccum Schrank. (cv. Holikovska), have been studied. Water deficit, induced PEG, as well treatment with NPs (...

in order to quantify and simulate the response of lemon balm (melissa officinalis l.) plants to cadmium (cd) concentrations in the soil, a pot experiment was conducted using completely randomized design (crd) with three replicates during 2014. the treatment consisted of twelve cd concentrations from 0 to 300 mg kg-1 of cd in the soil which was mixed with the experimental soil before planting. l...
