Leaf Phenological Stages of Winter Oilseed Rape (Brassica napus L.) Have Conserved Photosynthetic Efficiencies but Contrasted Intrinsic Water Use Efficiencies at High Light Intensities

Leaf Senescence, Root Morphology, and Seed Yield of Winter Oilseed Rape (Brassica napus L.) at Varying Plant Densities

In this study, the yield and yield components were studied using a conventional variety Zhongshuang 11 (ZS 11) and a hybrid variety Zhongyouza 12 (ZYZ 12) at varying plant densities. The increase in plant density led to an initial increase in seed yield and pod numbers per unit area, followed by a decrease. The optimal plant density was 58.5 × 104 plants ha-1 in both ZS 11 and ZYZ 12. The furth...

Leaf senescence and nitrogen remobilization efficiency in oilseed rape (Brassica napus L.).

Despite its worldwide economic importance for food (oil, meal) and non-food (green energy and chemistry) uses, oilseed rape has a low nitrogen (N) use efficiency (NUE), mainly due to the low N remobilization efficiency (NRE) observed during the vegetative phase when sequential leaf senescence occurs. Assuming that improvement of NRE is the main lever for NUE optimization, unravelling the cellul...

The Use of Herbicides in Biotech Oilseed Rape Cultivation and in Generation of Transgenic Homozygous Plants of Winter Oilseed Rape (Brassica napus L.)

Transformation And Light Inducible Expression of cry1Ab Gene in Oilseed Rape (Brassica napus L.)

Rapeseed (Brassica napus L.) is the third most important oil crop in global productions. One of the major limiting factors for oilseed rape production is lepidopteran pests of the Brassicaceae family. Transgenic plants expressing Bacillus thuringiensis (Bt) genes are powerful tools in the integrated pest management of crop plants. In the present study, we used a synthetic Bt insecticidal crysta...

Ideotype Population Exploration: Growth, Photosynthesis, and Yield Components at Different Planting Densities in Winter Oilseed Rape (Brassica napus L.)

Rapeseed is one of the most important edible oil crops in the world and the seed yield has lagged behind the increasing demand driven by population growth. Winter oilseed rape (Brassica napus L.) is widely cultivated with relatively low yield in China, so it is necessary to find the strategies to improve the expression of yield potential. Planting density has great effects on seed yield of crop...
