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( ...

This research is an experimental study that aims to determine the effect of application N2-fixing bacteria Actinomycetes, Azospirillum, and Azotobacter on vegetative growth parameters corn plants nitrogen content plants. Parameters for measuring include: formation rate radicle length, plant height, number leaves, leaf fresh weight plants, roots, dry total N in as well physical chemical qualitie...

in the recent years application of allelopathic effects in weeds managment have attracted the attention of many researchers. to study the effects of water extracts and various amount of plants powder of sinapis, achillea, salvia, artemisia and wanut leaf on seed germination and seedling growth of bean, two separate factorial experiments were carried out in completely randomized design, with 3 a...

in a completely randomized design, the effect of the extract from trifolium alexandrium (0, 0.2 and 0.4%) on the germination, some morphological characteristics, photosynthetic pigments, and nutrients uptake of prosopis cineraria was evaluated. the highest germination rate and percentage (9.16 and 21%, respectively) were recorded in the 0.2% treatment. the maximum and minimum lengths of radicle...

in order to evaluate the allelopathic effects of white top (cardaria draba (l.) desv.) water extracts on corn and canola germination characteristics, an experiment was carried out based on crd design with three replications in agronomy research lab of yasouj university. treatments were included of 25%, 50%, 75% and 100% water extract (50 gr dm/l) of root, leaf and stem, inflorescence and whole ...

Allelopathy refers to the chemical inhibition or stimulation of one species by another which could influence on the growth or germination of other plant and used in control of weed in agricultural practices. In this sense in order to study the possibly allelopathic effects of lemon balm, bitter apple and lemon verbena medicinal plants on control of wild mustard weed, a laboratory experiment was...
