The activity-guided fractionation of the MeOH extract of the flower of Paulownia coreana led to the isolation of a new geranylated flavanone, 3'-O-methyl-5'-hydroxydiplacol (1), along with 10 known compounds (2-11). Their structures were determined using spectroscopic techniques, which included one and two dimensional (1- and 2D)-NMR. Among the isolates, compounds 1-6 showed potent inhibitory a...
bending and compression strength of paulownia fortunie wood grown in educational and research forest located at shastkalate, gorgan were studied. paulownia trees were selected among five years old plantation. sampling spot was conducted following standard procedure. trees were cut into logs, which were then cut into 6 cm thickness wood blocks based on geographic directions. wood blocks were div...
چکیده به¬منظور جلوگیری از تخریب بیشتر اراضی جنگلی در حاشیه روستاهای مناطق کوهستانی و اراضی عاری از پوشش جنگلی، تعداد 11گونه و کلن از ارقام پرمحصول و تند رشد صنوبر و پالونیا جهت تعیین میزان سازگاری و موفقیت آنها انتخاب گردید و در ارتفاعات جنگلی فریم منطقه سنگده در استان مازندران نسبت به کاشت نهال از ارقام مورد نظر که بر اساس تجربیات و مطالعات اولیه حاکی از توان سازگاری، استقرار و تولید چوب مناس...
چکیده هدف از این مطالعه ارزیابی ارتباط بین مدول دینامیکی (moed) در درختان سرپای سالم پالونیا فورتونی (چوب پالونیا) و مدول استاتیک (moes) بود. برای این منظور تکنیک غیر مخرب موج تنش استفاده شد. این تحقیق روی 14 درخت سرپای سالم پالونیا فورتونی انجام شد. قطر تنه در ارتفاع سینه در دو کلاسه قطری، 31-25 سانتی متر و 37-31 سانتی متر در نظر گرفته شد. اندازه گیری های سرعت موج به طور عرضی در جهت شعاعی در ...
Agricultural research in the 21st century has become a collaborative effort. Research on crop pests like Spodoptera frugiperda (J.E. Smith), commonly known as the fall armyworm (FAW), can involve international collaboration because it is a pest not only in the southern United States, but also in Latin and South America. Our interest to study the genetic variation of 24 subpopulations of FAW fro...
Paulownia tomentosa is an important economic and greening tree species that is cultivated widely, including salt environment. Our previous studies indicated its autotetraploid induced by colchicine showed better stress tolerance, but the underlying molecular mechanism related to ploidy and salt stress is still unclear. To investigate this issue, physiological measurements and transcriptome prof...
The aim of the paper was to introduce an algorithm by which a production method any complex liquid solution can be done using multistage plug flow reactor from “Innovative Engineering”. example given in is modified nutrition for Paulownia with increased sequestration potential carbon polygon environment. designed continuously mix liquids order create consistent up 7 components if only one used....
