Effects of Seed Priming and Foliar Treatment with Ascorbate, Cysteine, and Triacontanol on Canola (Brassica napus L.) under Field Conditions

Studies conducted in controlled environments showed that seed priming and foliar treatments with various bioactive substances can stimulate germination, uniform seedling emergence, photosynthesis, nutrient uptake efficiency lead to increased productivity, crop stand, quality. Only a few studies provide comparative experimental outlook about the use of open-field cultivated canola. The aim this study was investigate effects treatment ascorbate (AsA), cysteine (Cys), triacontanol (Tria) on growth yield parameters two canola cultivars rapeseed (“Factor” “Hybrirock”) under conditions for three growing seasons temperate from Central Transylvania. Plant were recorded at different plant development stages: autumn (early vegetative period), spring, harvest. Not all have undergone laboratory testing successful field. Seed 10 ppm Cys AsA had beneficial seedlings, whereas their application enhanced number silique, yield, oil content studied cultivars. Tria visible biometrics only also root parameters, but some cases, no effect plants, or even negative could be observed important agriculture such as estimated yield/plant, content. Optimizing by determination lowest effective concentration, together frequency persistence are crucial cost-effectiveness.
