Despite the numerous studies on the effect of the magnetic field on plants, the exact mechanism of these effects has not yet been determined. The aim of this study was to compare the effect of magnetic field on growth and photosynthetic characteristics of two almond species (Amygdalus scoparia and A. eburnea). For this purpose, 21-day-old almond plants were affected by 10 mT static magnetic fie...
این تحقیق با هدف تعیین اثر دگرآسیبی عصاره آبی درمنه کوهی (Artemisia aucheri Boiss.) بر خصوصیات جوانهزنی و رشد اولیه بادام کوهی (Amygdalus scoparia) و بهصورت آزمایشگاهی در قالب طرح کاملاً تصادفی با شش تیمار عصاره آبی اندام هوایی درمنه کوهی در پنج غلظت 15، 30، 45، 60 و 75 گرم در لیتر و آب مقطر (شاهد) در سه تکرار انجام و نتایج پس از تجزیه واریانس یکطرفه، مقایسه می...
This study was carried out to investigate the effect of crown canopy of Pistacia atlantica, Amygdalus scoparia and A. eburnea species on seed bank density (size). Ten individuals of each species were selected and one plot under and another plot outside of the crown canopy of each species were established. In each plot, soil sampling was done from 0-5 and 5-10 cm depths. The soil seeds were id...
Field, greenhouse, and laboratory experiments were conducted at the Montana State University Southern Agricultural Research Center, Huntley, MT, USA, in 2012 and 2013, to evaluate the effectiveness of various postharvest-appliedherbicideson late-season control, fecundity, seed viability, andprogenyfitnessofKochia scoparia (kochia) in wheat stubble. Paraquat þ atrazine, paraquat þ linuron, and p...
Aphid parasitoids of the subfamily Aphidiinae (Hymenoptera: Braconidae) of northeastern Iran were studied in this paper. A total of 29 species are keyed and illustrated with line drawings. The aphidiines presented in this work have been reared from 42 aphid host taxa occurring on 49 plant taxa from a total of 33 sampling sites. Sixty-six aphidiine-aphid-plant associations are presented. Trioxys...
Hypericum perforatum (St. John's wort) is well-established for its antidepressant activity throughout the world and also various other species within this genus are used in different folk medicines. Hyperforin of St. John's wort inhibited growth of cancer cell lines and the use of hypericin (another compound of H. perforatum) in cancer photodynamic therapy is proposed. Therefore, we investigate...
Maintaining the stability of exotic sand-binding shrub has become a large challenge in arid and semi-arid grassland ecosystems northern China. We investigated two kinds shrublands with different BSCs (biological soil crusts) cover desert steppe Northwest China to characterize water sources (Caragana intermedia Kuang et H. C. Fu) grass (Artemisia scoparia Waldst. Kit.) by stable 18O isotopic. Ou...
