The study on the elemental composition of the feverfew herb (Tanacetum parthenium (L.) Schultz bip.)
Natural rubber is produced by a rubber transferase (a cis-prenyltransferase). Rubber transferase uses allylic pyrophosphate to initiate the rubber molecule and isopentenyl pyrophosphate (IPP) to form the polymer. Rubber biosynthesis also requires a divalent metal cation. Understanding how molecular weight is regulated is important because high molecular weight is required for high quality rubbe...
Variation in the effectiveness of biocontrol agents on the weed Parthenium hysterophorus L. was evaluated at two properties (Mount Panorama and Plain Creek) in Queensland, Australia for four years (1996-2000) using a pesticide exclusion experiment. At Mount Panorama, higher levels of defoliation by the leaf-feeding beetle Zygogramma bicolorata Pallister and galling by the moth Epiblema strenuan...
Dear Editor, We read with great interest the article by Gardiner et al1 discussing adverse events associated with herbal medicine use in children and wish to congratulate the authors on highlighting potentially harmful effects of herbal medicine use. We also wish to raise awareness of the anti-thrombotic properties of commonly used herbal medications such as ginkgo, omega-3 oils, vitamin E, fev...
asteraceae بزرگ ترین تیره گیاهان گل دار می باشد که دارای 1500 جنس و 23000 گونه است. این خانواده دارای خواص بسیار متفاوت و مهمی مانند خاصیت داروئی، حشره کشی، زینتی و خوراکی می¬باشند. بنابراین مطالعات وسیعی نیز از جنبه های مختلف بر روی اعضاء این تیره انجام گرفته ولی با توجه به پراکنش وسیع و فراوانی گونه¬های آن، مطالعات انجام شده، به ویژه مطالعات رویان شناختی، بسیار اندک است. یکی از جنس های بزرگ ...
The present investigation focused on the effects of plant and seed diffusates of Parthenium hysterophorus L. on seed germination of Raphanus sativus L. Level of glucose in germinating seeds as an indirect measure of amylase activity was estimated. About 91.66% viable seed of Raphanus sativus were treated in different concentrations of rhizospheric soil diffusates (PD) and germinating seed diffu...
Photosynthetic effects of the leaves extracts from Ipomoea cairica on Parthenium hysterophorus L were studied. Ipomoea cairica dried leaf powder (20g) was dissolved in distilled water (200ml) for foliar application. The seedlings were maintained under natural condition in Insect free net house. The experiment was carried out to analyze the effects of Ipomoea cairica leaves extract by measuring ...
