We have investigated the influence of stress conditions such as incubation at 4 degrees C and incubation in hyperoxygen atmosphere, on plant tissues. The ubiquinone (Q) content and respiratory activity of purified mitochondria was studied. The rate of respiration of mitochondria isolated from cold-treated green bell peppers (Capsicum annuum L) exceeds that of controls, but this is not so for mi...

The present study was conducted on sprouts (5 and 7 days) of turnip (Brassica rapa), cauliflower (Brassica oleracea) and mustard (Brassica juncea) for bioactivity. Their antioxidant potential was assessed by 2,2-diphenyl-1-picrylhydrazyl, superoxide anion radical scavenging assays at 0.125-2 mg/ml concentration. The extract of turnip, cauliflower and mustard (5 and 7 days) showed a potent antio...

A protein with structure-specific endonuclease activity has been purified to near homogeneity from cauliflower ( Brassica oleracea var. botrytis) inflorescence through five successive column chromatographies. The protein is a single polypeptide with a molecular mass of 40 kDa. Using three different branched DNA structures (flap, pseudo-Y and stem-loop) we found that the enzyme, a cauliflower st...

Vegetables (Beta vulgaris L., Abelmoschus esculentus L. and Brassica oleracea L.) from the production and market sites of India were tested for Cu, Cd, Zn and Pb. At market sites, the mean concentration of Cu in cauliflower, and of Zn and Cd in both palak and cauliflower had exceeded the PFA standard. Zn at the production sites also exceeded the PFA standard in cauliflower. Cd concentration in ...

Intercropping systems are one of the sustainable agricultural models as they play an important role in protecting soil fertility, efficient use resources, maintaining stable yields, and reducing effectiveness diseases pests. The aim this study was to investigate effects intercropping (IC) cauliflower (Brassica oleracea L. var. botrytis) with leaf lettuce (Lactuca sativa crispa) on yield quality...

Methods were developed to monitor persistence of genomic DNA in decaying plants in the field. As a model, we used recombinant neomycin phosphotransferase II (rNPT-II) marker genes present in genetically engineered plants. Polymerase chain reaction (PCR) primers were designed, complementary to 20-bp sequences of the nopaline synthase promoter in a transgenic tobacco and the cauliflower mosaic vi...

Plutella xylostella (Linnaeus, 1758), the diamondback moth is an important pest in Brassicae cultivars world. However, description regarding different biological stages and information about performance parameters of P. are to survey fields design effective management. In this study, wild population was adapted on white cabbage then cauliflower, broccoli leaves were tested under laboratory cond...

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...
