از آنجایی که تنشهای خشکی تولید محصول و مواد مؤثره در گیاهان را تحت تأثیر قرار می دهد، در تحقیق حاضر به بررسی اثر تیمارهای مختلف آبیاری بر برخی عاملهای رشد از جمله ارتفاع، قطر یقه، گستردگی تاج پوشش، وزن تر و خشک پایه های ارقام مختلف گیاه وایول (parthenium argentatum gray.) پرداخته شده است. این طرح با استفاده از طرح آماری اسپلیت پلات در چهار سطح آبیاری کامل (در حد ظرفیت زراعی)، تنشهای ملایم (4/3 ...
botrytis cinerea is an important pathogen that causes diseases in ornamental crops. in presentresearch several greenhouses of roses located in central region of iran were surveyed toidentify the botrytis cinerea. a total of 80 isolates were collected from rose greenhouses incentral region of iran. morphological identification was based on characters such asconidiophore and conidial length. acco...
Abstract: The present study deals the theoretical modeling aspects of coupled conductive and radiative heat transfer in the presence of absorbing, emitting and scattering gray medium within two-dimensional square furnace including two flames. The gray radiative medium is bounded by isothermal walls which are considered to be opaque, diffuse and gray. The well known discrete ordinate method (DOM...
Background and purpose: Today, due to the reduction of water resources, separation of gray water from domestic wastewater and its reuse has gained more interest. The aim of this study was to apply multi-layer filtration (MLF) for removal of nutrients from gray water. Materials and methods: This laboratory-scale study was carried out in 2.3-19.2 gr. COD / L. d organic loading rates (OLR) over a...
