The effect of four water salinity levels (0.75, 5, 10 and 15 dS.m -1 ) on growth indices and physiological parameters in some wild pistachio (P. atlantica, P. atlantica subsp. kurdica, P. atlantica subsp. mutica and P. atlantica subsp. cabulica) were investigated under greenhouse conditions. Leaf dry weight was reduced to about 30-54% at ECw 10 dS.m -1 . Chemical analysis of shoot and root indi...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

Annual fluxes of canopy-level heat, water vapour and carbon dioxide were measured using eddy covariance both above the aspen overstory (Populus tremuloides Michx.) and hazelnut understory (Corylus cornuta Marsh.) of a boreal aspen forest (53Ð629 °N 106Ð200 °W). Partitioning of the fluxes between overstory and understory components allowed the calculation of canopy conductance to water vapour fo...

abstract silicon (si) is considered one of the beneficial elements for plant, however recent studies show that si plays an important role in plant resistance to environmental stresses , like salinity. an experiment was conducted to study the effect of si and nacl salinity on the growth, yield and fruit quality of strawberry (fragaria × ananassa duch) cv “selva” was grown hydroponically in the c...

New irrigation methods under different nutritional element supplies for maize production was designed and tested for evaluate quantitative and qualitative parameters by split-plot arrangement according complete randomized block design with three replications. Different Irrigation regimes was belonged to main plots (Conventional furrow irrigation: CFI or A1, Alternate furrow irrigation: AFI or A...

BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...

in order to evaluate the effect of terminal water deficit stress on leaf traits and their relations to grain yield in different barley genotypes (‘yousof’, ‘fajr30’, ‘nosrat’, ‘pbyt-46’, ‘pbyt-97’ and ‘morocco’), two separated experiments were conducted in stress (water withholding from anthesis towards the end of growing season), and non stress (normal irrigation) conditions based on rcbd with...

The association between spectral reflectance and canopy processes remains challenging for quantifying large-scale canopy phenological cycles in tropical forests. In this study, we used a tower-mounted hyperspectral camera in an eastern Amazon forest to assess how canopy spectral signals of three species are linked with phenological processes in the 2012 dry season. We explored different approac...

This experiment was conducted in 2012 at the research field of Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran, to study the effect of chemical and biological fertilizers on Sage (Salvia officinalis L.) and replacing biofertilizers instead of high doses of chemical fertilizers. The experiment was conducted in factorial in the form of a randomized complete bloc...
