Nanoparticles are atomic or molecular particles with at least 1–100 nanometer diameters. They have entered vastly into the world of agriculture and biology; this is because of their special effect and their unique features. Their unknown impact on living things and the ecosystems has caused a lot of concern. This research was done in order to study the effects of nano-TiO2 and nano aluminium on...

The effects of Drought and salinity stress on the growth and chemical compositions pennyroyal(Mentha pulegium L.) plant were investigated. This experiment was carried out in a factorial-randomized design with four replications in controlled conditions and plantlets were subject to four soil moisture regimes (40, 60, 80 and 100 of field capacity (FC)) and five salt treatments with 0, 25...

A pot experiment was conducted based on a factorial study and complete random block design with three replicates to investigate the phytoremediation potential of Sorghum biocilor L. in soils polluted with nickel and manganese during 2017-2018. The first factor was nickel nitrate (0, 60, and 120 mg kg-1 soil) and the second factor comprised of manganese sulphate (0, 50, and 100 µM). The characte...

in order to investigate the effect of concentration, time and consumption instruction of seaweed on some morphological characteristics of root and shoots of safflower, the present experiment in factorial form in a completely randomized design with three replications in research greenhouse of agriculture faculty, ferdowsi university of mashhad was conducted in 2014-15. factors examined included ...

Chromium is a heavy metal toxic for plants that due extensive industrial applications over the last decade, has become a serious environmental pollution. On the other hand, chelator dissolution and absorption of metal by the plant increase and their use in phytoremediation is important. The aim of this study was to evaluate the effect of different concentrations of chromium and ethylene diamine...

environmental stress especially drought is one of the most important factors to reduce and disturbance in different stages of floral growth especially sprouting in dry and semi-dry lands of iran. for this purpose a factorial essay executed in accidentally manner with four iterations in vitro condition. four genotypes of bromus tomentellus pasture types were used (92 tehran, 630 kordestan, 3414 ...

in order to investigate the effect of root pruning in morphological and physiological characteristics of juniperus excelsa seedlings an experiment was carried out on transplanted one year-old seedlings. treatments included root pruning intensities (1-slight pruning (2-moderate pruning and 3- control (no root pruning)) .experiment design was completely randomized design. each treatment included ...

Pistacia vera L. is a decidious tree. To investigate the influence of soaking seeds in polyamines (PAs) spermine (Spm), spermidine (Spd) and putrescine (Put) on seed germination and enhancing lateral root development of ‘Ghazvini’ pistachio seedling rootstock, the experiment were carried out in petri dishes and plastic bags. Seeds were soaked in PAs( Spd, Spm, and Put) at three concentrations( ...
