Intraspecific Variability of Floral Nectar Volume and Composition in Rapeseed (Brassica napus L. var. oleifera)
Numerous angiosperms rely on pollinators to ensure efficient flower fertilization, offering a reward consisting of nourishing nectars produced by specialized floral cells, known as nectaries. Nectar components are believed to derive from phloem sap that is enzymatically processed and transformed within nectaries. An increasing body of evidence suggests that nectar composition, mainly amino acid...
متن کاملSome Biochemical Parameters of Brassica napus L
s: Chromium is one of the unessential heavy metal that makes high toxicity in the plants. The aim of this study was assaying the changes that come from toxicity of (Cr ) on some biochemical, physiological and 6+ ionic specification of Brassica napus variety sari flower. The tests were conducted at hydro ionic conditions and at 0, 25, 50, 75 and 100 μm concentration of K CrO with four repeats in...

متن کاملChromosome Doubling of Microspore-Derived Plants from Cabbage (Brassica oleracea var. capitata L.) and Broccoli (Brassica oleracea var. italica L.)
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high level of fertility. In the present paper, 29 populations of microspore-derived plantlets from cabbage (Brassica oleracea var. capitata) and brocc...
متن کاملTranscriptomic basis for drought-resistance in Brassica napus L.
Based on transcriptomic data from four experimental settings with drought-resistant and drought-sensitive cultivars under drought and well-watered conditions, statistical analysis revealed three categories encompassing 169 highly differentially expressed genes (DEGs) in response to drought in Brassica napus L., including 37 drought-resistant cultivar-related genes, 35 drought-sensitive cultivar...
