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...
Rose is one of the most important flowers in the world, and is ranked first in the market of cutting flowers. An experiment was carried out to study the effects of different planting substrate on the quality and quantity of rose (Rosa hybrida var. Grandgala) flower. In this experiment, one-year-old rooted cuttings of commercial rose cv. Grandgala were transferred into different growing media in...
In order to evaluate the effect of medium and spraying calcium nano-fertilizer on quality of cut gerbera flowers, an experiment was conducted as factorial in completely randomized design with 7 media and 3 calcium nano-fertilizer concentrations with 3 replications. The media included cocopeat + perlite (1:1), peat moss + perlite (1:1), mushroom compost + perlite (1:1), peat moss + cocopeat + pe...
Growth media have important effects on the development of ornamental plants. Many organic and inorganic materials are used in as growing (GM) The present study was carried out Atatürk University controlled greenhouses condition. In study, 11 different created with sand, soil, peat, perlite, coconut peat their mixtures were media. Mixing medium a volumetric basis (V:V), respectively: Mix 1: peat...
Potato (Solanum tuberosum L.) is one of the most important economical vegetable. Minitubers are small seed tubers without pathogens that are produced from invitro plantlets after translocation to greenhouse and create healthy and high quality seed tubers. Hydroponic systems increase the production of virus-free potato minitubers. This research was carried out to study the effect of different gr...
In the present work, co-immobilization of cholesterol oxidase (COD) and horseradish peroxidase (POD) on perlite surface was attempted. The surface of perlite were activated by 3-aminopropyltriethoxysilane and covalently bonded with COD and POD via glutaraldehyde. Enzymes activities have been assayed by spectrophotometric technique. The stabilities of immobilized COD and POD to pH were higher th...
Statistical models using multiple linear regression are some of the most widely used methods to study the influence of independent variables in a given phenomenon. This study's objective is to understand the influence of the various components of aerogel-based renders on their thermal and mechanical performance, namely cement (three types), fly ash, aerial lime, silica sand, expanded clay, type...
Groups of 21 male and 21 female mice were given diets containing 20%, 10%, 1% or 0% (control) perlite for 28 weeks. Appearance, behavior, mortality, and food consumption of mice of treated groups were not affected during the experimental period. Males of the 20% and 10% groups did experience slightly reduced growth rate. No significant drug-related changes were found in urinalysis, hematology, ...
