Nitrogen concentration affects growth and bolting of plants, but its regulation mechanism is still unclear. In this work, three nitrate treatments (5%, 100%, 200%) in nutrient solution were conducted to explore the internal relationship between nitrogen flowering Chinese cabbage. The results showed that time was earlier under treatment with low and, lower concentration, flowering. Low-nitrate r...

Plutella xylostella cause considerable harm to the production of broccoli, Chinese cabbage, cabbage and cauliflower. The control P. is mainly performed using commercial insecticides, which have even led emergence resistant populations. Two easily available natural products found in different plants essential oil, thymol eugenol, stand up as possible novel agents this pest. In work a series alky...

Vernalization is required to induce flowering in cabbage (Brassica oleracea var Capitata L.). Since FLOWERING LOCUS C (FLC) was identified as a major repressor of flowering in the vernalization pathway in Arabidopsis (Arabidopsis thaliana), two homologs of AtFLC, BoFLC3-2 and BoFLC4-1, were isolated from cabbage to investigate the molecular mechanism of vernalization in cabbage flowering. In ad...

Yellow rocket, Barbarea vulgaris (R. Br.) variety arcuata, was evaluated as a trap crop for diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), in cabbage, Brassica oleracea L. variety capitata, in 2003 and 2004. In 2003, the numbers of P. xylostella larvae found in field plots of cabbage alone were 5.2-11.3 times higher than those on cabbage plants in plots that included cab...

Flowering time is important for Brassica rapa vegetables because premature bolting before harvest can lower yield and quality. FLOWERING LOCUS C (FLC) acts as a key repressor of flowering. In this study, we identified nonsynonymous mutation at the 58th nucleotide exon1 in BrFLC1 (named Pe1+58 (A/C)) by screening resequencing data 199 B. accessions verified being related to flowering variation. ...

Lysophosphatidic acid (LPA) is a lipid mediator that plays a role in the process of wound healing in animal tissues, including the digestive tract. We determined LPA in several foodstuffs, and found that cabbage leaves were the richest source of LPA. We also found that, at 22 and 195 nmol/g (wet weight), LPA and phosphatidic acid (PA) were respectively formed during mastication of raw cabbage l...

this study analyzed the performance of cabbage marketing in abia state, nigeria. specifically the study sought to: describe socio-economic characteristics of cabbage marketers; identify marketing channels of cabbage; determine marketing cost components of cabbage marketers; determine marketing margins, market share and marketing efficiency of cabbage marketers; and determine socio-economic fact...
