The purpose of this paper is to compare major models for height estimation of Picea orientalis L trees based on the individual tree diameter and certain other stand variables. The data were collected from 440 trees of pure and even-aged P. orientalis stands that are located near Artvin in the northeastern part of Turkey. The data from 406 trees were used for model development and the remaining ...
BACKGROUND The increasingly high incidence of ischemic stroke caused by thrombosis of the arterial vessels is one of the major factors that threaten people's health and lives in the world. The present treatments for thrombosis are still unsatisfactory. Herbal preparations have been used since ancient times for the treatment of several diseases. The aim of this study was to investigate whether h...
آلودگی هوا بر رشد و کیفیت درختان در فضای سبز شهری تأثیر بسزایی دارد، زیرا صدمات مزمنی در اثر جذب مداوم آلایندهها ایجاد میشود. امروزه ایجاد فضای سبز مناسب در مناطق شهری موجب کاهش صدمات زیانآور آلودگیهای محیطی میشود. این پژوهش با هدف بررسی تأثیر آلودگی هوا بر مقدار هیدرات های کربن و پرولین درخت چنار (Platanus orientalis L.) در سطح شهر ارومیه انجام شد. برای این منظور پنج پارک بوستان با درجه ...

High-resolution magnetic resonance (MR) images of the brain of an adult spinner dolphin (Stenella longirostris orientalis) were acquired in the coronal plane at 55 antero-posterior levels. From these scans a computer-generated set of resectioned virtual images in the two remaining orthogonal planes was constructed with the use of the VoxelView and VoxelMath (Vital Images, Inc.) programs. Neuroa...
In this study, ITS–rDNA region was used to identify some anamorphic powdery mildews in Guilan province. According to the results, Erysiphe species on Vicia faba and Sesbania punicea showed 100% similarity to each other, however, without ITS sequence of holotype of E. sesbaniae it is impossible to make conclusion whether Vicia faba powdery mildew fungus actually belongs to E. sesbaniae or E. tri...
Transcription and alternative splicing (AS) are now appreciated in plants, but few studies have examined the effects of changing ploidy on transcription AS. In this study, we showed that artificially autododecaploid plants London plane (Platanus × acerifolia (Aiton) Willd) had flowers relative to their hexaploid progenitors. Transcriptome analysis based full-length Oxford Nanopore Technologies ...
Over three consecutive years in central Mississippi, sweetgum (Liquidambar styraci/lua L.) and sycamore (Platanus occidentalis L.) fruits had nearly reached fullsize by late June. Sweetgum seeds were physiologically mature by mid-August, but dry weight increased until late September. As sweetgum seeds matured, the crude fat level rose to 27 percent of seed dry weight. During maturation, concent...
Old trees as the most important genetic reserves of the country have great importance and value in various aspects of ecology, forest restoration management, ecotourism and even history. In this research, after identification of the old trees in the forests of Ilam province, their morphological characteristics including DBH, trunk height, total height, crown length, min & max crown diameter, cr...
