Physiological analysis of growth and development of winter carinata ( <i>Brassica carinata</i> A. Braun)

Brassica carinata is a non-food, low-carbon, none-to-low indirect land-use change impact oilseed feedstock grown for sustainable biofuels, bioproducts, and high protein seed meal. Understanding growth development critical to the of best management practices maximum productivity profitability double-cropped farming systems. Field experiments were conducted during 2017–2018 (Year 1) 2018–2019 2) winter–spring growing seasons in Quincy, Florida, quantify total aboveground dry matter accumulation (TDM), allocation, growth, nutrient uptake, quality. The two cultivars Avanza 641 AX17012 accumulated 10826 9343 kg TDM ha−1 Year 1 9655 10,642 2, respectively, at harvest maturity. proportion DM vegetative parts such as leaves stems decreased, reproductive structures silique walls seeds increased with Seed yield (SY) was similar between but differed years (2732 ha−1), producing 29% greater SY than 2 (1929 ha−1). Carinata primary stem has 17–20 leaf nodes, 75%–88% axillary meristems secondary branches. Crop rate (CGR) from pod both 1, while attained CGR bolting/flowering stages, respectively. Maximum seasonal uptake leaves, stems, siliques generally occurred early, mid, late season, years. weight, oil, monounsaturated fatty acids, C18:3, C20:1, C22:1 concentrations plant age, whereas protein, glucosinolate, polyunsaturated saturated C18:1, C18:2 decreased These results can be used crop modeling predict development, aid developing in-season decision support tools.
