salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

   Phenolic extracts of canola (Brassica napuse L.) contains substances that inhibited the germination and seedling growth of soybean (Glycin max L.). These compounds also affect activity of some enzymes. Hear, we investigated the allelopathic effects of various canola plant parts on soybean germination, seedling growth, and biochemical aspects. Phenolic extract of canola shoot (including leaf,...

Pistacia vera cv Badami-e-riz and P.vera cv Ghazvini are the most important and popular rootstocks in Iran, which tolerate salinity and phytophthora fungi. This study was conducted to evaluate the effects of various concentrations of polyamines and IBA on root regeneration of transplanted bare- rooted ‘Badami-e-riz’ and ‘Ghazvini’ pistachio rootstocks. The mean comparison between IBA and polyam...

modern biotechnology and genetic engineering using techniques and special ‎laboratory tools plays an important role in the pharmaceutical industry and medicinal ‎plant propagation. among these techniques, it can be noted that a wide range of ‎elicitors are widely used for inducing metabolites at invitro culture. due to the ‎pharmaceutical properties of artichoke and its history, it has been dee...

The effect of seaweed liquid fertilizer (SLF) of Sargassum myriocystum on germination, growth and biochemical constituents of Vigna mungo was studied. Different concentrations (5%, 10%, 25%, 50% and 75%) of SLF were prepared using distilled water. A total of 100 seeds were soaked for each SLF concentration for a 24-h period and were later placed in various Petri plates and watered regularly. Wa...

to study the effect of aquazorb super absorbent polymer (sap) on reducing drought stress of acacia victoriae seedling, a split plot experiment based on the completely randomized design was conducted. in this research, stressed treatment as the main plots and amount of superabsorbent were considered as sub plot. treatments were applied consisted of four levels of drought stress (15, 30, 60 and 1...

Seed treatments of improved Kentucky bluegrass and fescue cultivars with carbofuran, oxamyl, and phenamiphos dissolved in acetone reduced seedling emergence, but treatments were not extremely phytotoxic. Phenamiphos was the most toxic, particularly at the 5,000 mug/ml concentration. Fresh weight of grass clippings 35 d following planting generally was greater in treatments than in controls exce...

Several species of Phytophthora cause crown and root rot diseases of herbaceous and woody plants. Crown and root rot of pistachio trees cause significant damages in infected orchards. The effect of foliar application with Elite (fosetyl-Al) in 2 and 2.5 g/l was evaluated in greenhouse experiments. The frequency of mortality, fresh and dry weight of roots and shoots, height, intensity of crown r...
