In the course of field research, analysis previously published works and review materials stored in well-known collection funds Siberia (NS, KRAS, SSHZ), information on distribution rare adventitious native plant species Upper Yenisei basin was clarified. For first time, Arctium lappa, Armoracia sisymbrioides, Bupleurum sibiricum, Calystegia sepium, Lolium perenne, Pastinaca sativa, Polygonum s...

a multivariate statistical analysis was performed on morphological characters of sixty-one populations of avena eriantha dur. a. clauda dur., a. barbata pott ex link., a. wiestii steud., a. fatua l., a. sterilis ssp. ludoviciana l. and a. sativa l. factor analysis revealed that intraspecific morphological variations are due to quantitative characters. interspecific as well as intersectional rel...

background: the contamination of ecosystem with petroleum and its derivatives is con­sidered as one of the most crucial environmental threat in iran. application of micro­organisms has been demonstrated as an appropriate and more practical alternative to clean-up petroleum hydrocarbons in the contaminated environments. objectives: the objectives of this study were isolating rhizosphere-inhabiti...

It may sound a little nutty, but your friends are partially correct. Nutmeg, a spice commonly used to flavor lattes, sweets, and other foods has also been reported to produce a high that is similar to the one obtained with marijuana. Originating from the Myristica fragans tree in Indonesia, the seed is now grown and used globally, mostly for cooking but sometimes as a narcotic. However, for the...

Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was o...

Dormant seeds of Avena fatua, which do not germinate when allowed to imbibe water, have a respiration rate only about 20% less than that of imbibed nondormant (after-ripened) seeds in the period before actual germination and are capable of synthesizing protein at a rate comparable to that of the nondormant seeds. An increase of protein synthesis is observed in nondormant seeds at the beginning ...
