Mustard beetles (Phaedon cochleariae (Fabricius)) adhered slightly better to hairy leaves than to glaucous leaves of Brassica oleracea but by far the best adhesion was to glossy leaves. Scanning electron mierographs illustrate how adhesion between the climbing setae on the tarsi of P. cochleariae and the leaf surfaces was hindered by the vertical rods and dendritic plates on glaucous leaves. Th...
Severe root rot was observed in fields of cabbages (Brassica oleracea L.) in 2015 in China. Cardinal symptoms of this disease included root rot and wilting leaves. A fungus was isolated from diseased tissues consistently. Based on the morphological features and molecular analysis of the ITS-5.8S rDNA and D1/D2 domain of the 28S rRNA gene, it was identified as Plectosphaerella cucumerina. This i...
BACKGROUND Oilseed Brassica represents an important group of oilseed crops with a long history of evolution and cultivation. To understand the origin and evolution of Brassica amphidiploids, simple sequence repeat (SSR) markers were used to unravel genetic variations in three diploids and three amphidiploid Brassica species of U's triangle along with Eruca sativa as an outlier. RESULTS Of 124...
کلزا (.brassica napus l) یکی از محصولات دانه روغنی مورد توجه کشاورزان در ایران می باشد. شته مومی کلم brevicoryne brassicae (l.) یکی از آفات مهم کلزا در استان آذربایجان غربی است که خسارت سنگینی به این گیاه وارد می کند. با توجه به اهمیت این آفت مطالعه ای در دو قسمت مزرعه ای و گلخانه ای به منظور ارزیابی تحمل 21 ژنوتیپ کلزا نسبت به شته مومی کلم طی سال های 1385 تا سال 1387 انجام شد. طی سه سال آزما...
گیاه کلم پیچ با نام علمی brassica oleracea var. capitata یکی از سبزیجات مهم اقتصادی و با سطح وسیع کشت در شهرستان ارومیه از استان آذربایجان غربی می باشد. طی بررسی بیماری های کلم در فاصله سال های 1391-1389، گیاهان بالغ کلم های سفید (b. o. var. capitata f. alba) و کلم های قرمز (b. o. var. capitata f. rubra) (شکل 1) با نشانه های زرد شدن و ریزش برگ های بیرونی بوته ها، آبسوختگی، قهوه ای شدن و نرم شدن...
Intraspecific variation was examined among 25 mitochondrial DNAs (mtDNAs), representing between two and five lines of eight agriculturally important Brassica species. Each of the approximately 140 restriction sites surveyed was invariant within each species. Only two length polymorphisms, deletions of 700 bp and 100 bp in a Brassica nigra line, were detected. A single inversion polymorphism was...

Antioxidant activity of six Brassica crops-broccoli, cabbage, cauliflower, kale, nabicol and tronchuda cabbage-was measured at four plant stages with DPPH and FRAP assays. Samples taken three months after sowing showed the highest antioxidant activity. Kale crop possessed the highest antioxidant activity at this plant stage and also at the adult plant stage, while cauliflower showed the highest...
In these decades biocontrol, or biological control, is an alternative mean to control plant diseases. In several fungal biocontrol agents, GMC oxidoreductases are involved in biocontrol activity. For example, in Talaromyces fl avus (Klöcker) Stolk and Samson, a glucose oxidase (AAB09442), a member of GMC oxidoreductase, is involved in its biocontrol activity of Verticillium dahliae Klebahn (Sto...
Plants release volatile chemicals upon attack by herbivorous arthropods. They do so commonly in a dose-dependent manner: the more herbivores, the more volatiles released. The volatiles attract predatory arthropods and the amount determines the probability of predator response. We show that seedlings of a cabbage variety (Brassica oleracea var. capitata, cv Shikidori) also show such a response t...
