BACKGROUND It was shown that plants derived agents are being used for treatment of cancer. In this study, crude ethanolic extract of Consolida orientalis L., Ferula assa-foetida L., Coronilla varia L., Orobanche orientalis G. Beck were screened in vitro for cytotoxic activity on Hela (Human cervical carcinoma) cell line. OBJECTIVES We performed the present study to evaluate the in vitro cytot...
Multiple linear regression (MLR), adaptive network-based fuzzy inference system–ant colony optimization algorithm hybrid (ANFIS-ACOR) and artificial neural network–multilayer perceptron (ANN-MLP) were tested to model the bending strength of Glulam (glue-laminated timber) manufactured with a plane tree (Platanus orientalis L.) wood layer adhered different weight ratios (WR) modified starch/urea ...
Today, the resistance of plants to stress is one most basic and important problems. Plants are sufficiently resistant oxidative disorders that occur with sudden changes in physiological state organism. This suggests plant cells have an antioxidant system can protect against oxygen radicals singlet oxygen. They different from animals immune system. The article describes Platanus orientalis tree ...
Background and Objective: Today, the presence and increase of particulate matter is one of the serious factors that threaten human health. In the meantime, trees can accumulate airborne particles by their foliage. In this study, the accumulating ability of various PM by the leaf of some tree and shrub species was evaluated in Isfahan. Materials and Methods: 12 species of trees and shrubs were ...
فلزات سنگین یکی از مهمترین و شناخته شدهترین آلایندهها هستند که ورود آنها به محیطزیست سبب بروز صدمات و بیماریهای مختلفی میشود. این تحقیق با هدف تعیین وضعیت آلودگی خاک و برگ درختان چنار به عنصر نیکل، تخمین و پهنه بندی نیکل در سطح شهر رشت به استفاده از روش زمین آمار انجام شد. ابتدا 126 نمونه مرکب از خاک سطحی (0 – 30 سانتی متری) و 76 نمونه برگ از درختان چنار از حاشیه خیابانهای شهر رشت جمع ...
آلودگیهای محیط شهری بر گیاهان تأثیر نامطلوبی دارند و گیاه برای مقابله با چنین تنشهایی از نظر آناتومیکی تغییراتی را در برگهای خود به وجود میآورند. مطالعة حاضر بهمنظور اندازهگیری تجمع عناصر کادمیم، سرب، روی، مس، نیکل و کروم در برگ درختان چنار و پاسخ آناتومیکی این گونه به آلودگی موجود در شهر تهران و مقایسه آن با پارک جنگلی چیتگر (منطقه کمآلوده) انجام شد. برای این منظور، 20 اصله درخت سالم و...
A distinct black leafspot with fungal growth was found on Platanus orientalis ‘Digitata’ (cut-leaf oriental plane tree) in northern Sydney, New South Wales, Australia, February 2019. Morphological characteristics, internal transcribed spacer sequencing and phylogenetic analysis of the associated fungus identified it as Pseudocercospora platanigena (= Stigmina platani). This pathogen has previou...
heavy metals are one of the most important and the best known pollutants that its entry into the environment causes to appear damages and different diseases. this study aimed to determine the amount of nickel concentration in soil and leaves of platanus orientalis, estimate and mapping it in rasht city area by using geostatistic method. to achieve these goals 126 samples of surface soil (0-30 c...
