The bindweeds Calystegia sepium and Convolvulus arvensis are difficult to control chemically. Calystegia sepium is often a problem in maize or in vineyards, while C. arvensis is an important weed of cereals. The biological control of these weeds with insects or fungal pathogens has been investigated since 1970. More than 600 fungi collected in countries throughout Europe have been isolated in o...
It has been reported that wild Brassica and related species are widely distributed across Xinjiang, China, and there has been an argument for species identification. Seed coat microsculpturing (SCM) is known to be an excellent character for taxonomic and evolutionary studies. By identifying collections from Xinjiang, China, and combining SCM pattern, flow cytometry, and genome-specific DNA mark...
Two field experiment were conducted to evaluate the effect of different fertilizer on seed yield and oil content two Black cumin species (Nigella sativa Nigella arvensis), first was at Qlyasan Agricultural Research Station, College Engineering Sciences, University Sulaimani, second Kanipanka Sulaimani Directorate, Ministry Agriculture Water Recourses during autumn season 2020-2021. The laid out...
مقدمه: فنل ها از مهم ترین ترکیبات ثانویه می باشند که در پاسخ به شرایط محیطی در گیاهان تولید می شوند. غلظت و عناصر محیط های کشت نقش مؤثری در تولید این ترکیبات دارند. اکسیداسیون ترکیبات فنلی در محیط کشت موجب کاهش موفقیت در فرآیند کشت بافت یا پیچیده شدن مراحل آن می شود. هدف: مطالعه حاضر جهت بررسی اثر آنتی اکسیدان های مختلف و محیط های کشت در مهار بیوسنتز ترکیبات فنلی در کالوس های گیاه mentha arvens...
Plants are the natural factories for the synthesis of variety of bioactive compounds. This diverse chemical setup of the plants speaks their important role as biomedicine. These biomolecules are often toxic to both plants and animals. The methanolic extract of Calendula arvensis was screened for its toxic potential against Lemna minor, Artimia salina (Brine shrimps) larvae and some important gr...
Information exchange (or signaling) between plants following herbivore damage has recently been shown to affect plant responses to herbivory in relatively simple natural systems. In a large, manipulative field study using three annual plant species (Achyrachaena mollis, Lupinus nanus, and Sinapis arvensis), we tested whether experimental damage to a neighboring conspecific affected a plant's li...
