The major pests of cabbage, Brassica oleracea var. capitata on Guam are diamondback moth, Plutella xylostella; cabbage webworm, Hellula undalis; cutworm, Spodoptera litura; cabbage cluster caterpillar, Crocidolomia pavonana; the fleahopper, Halticus tibialis and aphids. In the past, Chinese cabbage, Brassica chinensis cv. Tempest for C. pavonana; radish, Raphanus sativus cv. Minowase Summer Cro...

Three terrestrial plant species, oat (Avena sativa ), Chinese cabbage (Brassica campestris cv. chinensis) and lettuce (Lactuca sativa), were exposed to different concentrations of herbicide TCA (sodium trichloroacetate) in a growth test according to guideline OECD # 208. Classical (i.e. germination and biomass) and biochemical (i.e., antioxydant enzyme activities) endpoints were investigated. G...

Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...

single and joint toxicity of chloramphenicol and hg acting on wheat (triticum aestivum l.), chinese cabbage (brassica campestris l.) and corn (zea mays l.) were investigated. the results showed positive correlations between root elongation inhibition of three plants and concentrations of pollutants added to soil (p

Chinese cabbage (Brassica rapa L. ssp. pekinensis) is a widely cultivated and economically important vegetable crop with typical leaf curvature. The TCP (Teosinte branched1, Cycloidea, Proliferating cell factor) family proteins are plant-specific transcription factors (TFs) and play important roles in many plant biological processes, especially in the regulation of leaf curvature. In this study...

Cytoplasmic male sterility (CMS) is universally utilized in cruciferous vegetables. However, the Chinese cabbage hau CMS lines, obtained by interspecific hybridization and multiple backcrosses of the Brassica juncea (B. juncea) CMS line and Chinese cabbage, show obvious leaf etiolation, and the molecular mechanism of etiolation remains elusive. Here, the ultrastructural and phenotypic features ...

The relationship between carotenoid accumulation and expression of carotenoid biosynthesis genes was investigated in the flowers, stems, young leaves, old leaves, and roots of Chinese cabbage (Brassica rapa subsp. pekinensis). Quantitative real-time PCR analysis showed that the mRNA levels of BrPSY, BrPDS, BrZDS, BrLCYB, BrLCYE, BrCHXB, and BrZEP leading to the production of carotenoids were hi...

The aim of this work was to construct a high-resolution genetic map for the dissection of complex morphological and agronomic traits in Chinese cabbage (Brassica rapa L. syn. B. campestris). Chinese cabbage, an economically important vegetable, is a good model plant for studies on the evolution of morphologic variation. Herein, two high-generation inbred Chinese cabbage lines, 'Huangxiaoza' and...

Due to drastic socio-economic changes traditional intercropping systems in China are endangered. New high yielding intercropping systems that can easily be mechanized have to be developed. By using environmental resources more efficiently intercropping often produces higher yields compared to monocropping. Solar radiation as the strongest growth factor plays a key role when designing new interc...
