Ailanthus altissima (Mill.) Swingle (Simaroubaceae) is a deciduous tree widely distributed throughout temperate regions in China, hence suitable for genetic diversity and evolutionary studies. Previous studies in A. altissima have mainly focused on its biological activities, genetic diversity and genetic structure. However, until now there is no published report regarding genome of this plant s...
various biological activities, such as antitumor, antimalarial, antifeedant, insecticidal, antiinflammatory, amoebicidal, and herbicidal effects. We are interested in such biologically active compounds and have isolated many quassinoids from plants, such as Brucea antidysenterica, Picrasma ailanthoides, and Brucea javanica. As part of these studies, we investigated the isolation of quassinoids ...
Insect herbivores can affect plant abundance and community composition, and theory suggests that herbivores influence plant communities by altering interspecific interactions among plants. Because the outcome of interspecific interactions is influenced by the per capita competitive ability of plants, density dependence, and intrinsic rates of increase, measuring herbivore effects on all these p...
درخت پردیس (ailanthus altissima) درختی مهاجم است. عصاره های اندام های مختلف این درخت برای تعیین اثرات کشنده گیاهی آن تحت شرایط آزمایشگاهی و گلخانه ای ارزیابی گردید. اجزای گیاه در بهار و پاییز جمع آوری شدند. در اولین آزمایش سطح سمیت بر جوانه زنی بذرها و رشد ریشه چه علف هرز lepidium sativum بررسی شد. جوانه زنی تحت تاثیر عصاره هایa. altissima قرار نگرفت اما طول ریشه چه به طور معنی داری کاهش یافت. ...
به منظور بررسی صفات مورفولوژیکی و فنولوژیکی خصوصیات 68 جمعیت از پنج گونه جنس آنتمیس (anthemis altissima l.، a. haussknechtii boiss. & reut.، a. pseudocotula boiss.، a. tinctoria l. و a. triumfettii (l.) all.) آزمایشی در قالب طرح بلوکهای کامل تصادفی در 3 تکرار در سال زراعی 91-90 در مزرعه ایستگاه تحقیقاتی البرز کرج اجرا شد. 13 صفت قطر طولی و عرضی تاج پوشش، سطح تاج پوشش، ارتفاع و تعداد گل در بوته...
Phytochemical characters were evaluated in a five-year-old lemon balm collection consisting of 15 and 13 subspecies officinalis and altissima accessions, respectively. Stems were lower in essential oil than leaves. First cut leaves (June) gave more oil than those of the second cut (August). Subspecies officinalis plants had leaf oils rich in geranial, neral and citronellal in various proportion...
About 130 species of genus Anthemis occur throughout the world. Thirty-nine of them could be found in flora of Iran. According to literature, this species was not the subject of research up to now and therefore its chemical composition is not well known. However, flavonoids, polyphenolic acids, terpene and sesquiterpene compounds were reported to be the major constituents of some other species ...

UNLABELLED PREMISE OF THE STUDY Microsatellite markers were developed in the perennial herb Solidago altissima from populations within its introduced range in Japan to assess its population structure and to facilitate tracking of invasion expansion. • METHODS AND RESULTS Using 454 pyrosequencing, 16 microsatellite primer sets were developed for S. altissima. The primer sets were tested on ...
Studies were carried out for 90days on the degradation of wood wastes of four economically important Nigerian trees; Terminalia superba, Mansonia altissima, Holoptelia grandis and Milicia excelsa by white rot fungus, Pleurotus tuber-regium a Nigerian edible mushroom. The pH of the wastes dropped to 4.0/4.2, 90days after incubation. On the contrary, amino nitrogen content of the wastes increased...
