To Select an appropriate medium for the growth of plant is one of the problems of most greenhouse owners in production of pot ornamentals. So, current research was conducted to evaluate effect of some available media in mixtured by perlite on the growth of pothos. Study was based on a completely randomized design with 5 treatments, 8 measuring times and 6 replications in a fiberglass greenhouse...

Oxygen deficiency can occur even in well-aerated substrates as the result of various factors. In crops grown in perlite bags, where perlite is wrapped in a polyethylene film with little surface open to the atmosphere, the dissolved oxygen concentration ([O2]) may be depleted quite rapidly at high growth rates and high substrate temperatures. This situation may occur in spring cycles of greenhou...

this experiment was designed to characterize the effects of size and concentration of an iranian clinoptilolite zeolite on the growth officus benjamina (starlight) in peat base media. ficus benjamina was stock rooted and grown in a peat consisting perlite (2: 1 v/v) (p: pe), zeolite (10, 20, 30 and 40 v/v %, two sizes 0.5-3 mm and 3-8 mm) instead of peat in p: pe (2: 1 v/v) media. ficus benjami...

The work aimed to study all the possible factors affecting efficiency of plant propagation via stem cuttings. Several factors including type of cutting, culture medium, type and concentration of growth regulators were investigated. These factors were studied on Ficus hawaii as woody tree and Chrysanthemum morifolium as herbaceous plant to investigate the effect of plant type factor. All experim...

The removal of hydrophobic pollutants in biofilters is often limited by gas liquid mass transfer to the biotic aqueous phase where biodegradation occurs. It has been proposed that the use of fungi may improve their removal efficiency. To confirm this, the uptake of hexane vapors was investigated in 2.6-L perlite-packed biofilters, inoculated with a mixed culture containing bacteria and fungi, w...

This study was conducted at Abi – Jarash farm, Damascus, Syria, during 2018/2019 and 2019/2020 growing seasons. The aim of this comparing the effect three different cultivation techniques saffron (Crocus sativus L.), which were soilless cultivation, within nutrient film technique (NFT), in substrates (mixture peat moss- perlite), addition to soil. An increasing vegetative growth measurements re...

The use of soil health indicators linked to microbial activities, such as key enzymes and respirometric profiles, helps assess the natural attenuation potential of soils contaminated with hydrocarbons. In this study, the intrinsic physicochemical characteristics, biological activity and biodegradation potential were recorded for two soils with different contamination histories (>5 years and <1 ...

this experiment was carried out to investigate the effect of different substrate on growth and yield of gerbera flower. the experiment was performed using 10 treatments as fallow: fine sand, peat +fine sand (%25+%75), peat + fine sand ( %50 +%50), perlite + peat (%75 + %25), perlite + peat (%50 + %50), perlite + peat (%25 + %75), perlite + peat + expanded clay (%25 + %70 + %5), perlite + peat +...
