Quantifying plant biomass and seed production in camelina ( <i>Camelina sativa</i> (L.) Crantz) across a large range of plant densities: Modelling approaches

To date, there has been little agreement on supporting the hypothesis that how some key vegetative traits of camelina (Camelina sativa (L.) Crantz var. ‘Soheil’) are dependent plant biomass. Therefore, main aim this investigation was to quantify relationship between size plants and seed production across a broad-range densities through modelling approaches. make wide range densities, fan design used in eight replicates an experimental field at Sari Agricultural Sciences Natural Resources University, Iran. relation density other traits, regression analysis carried out coefficient determination (R2) considered evaluate goodness fit model. A power model (y = axb) could describe well (ranged 113–2905 m−2) biomass, production, number seeds per plant, stem diameter, siliques number, with values 0.85, 0.87, 0.65, 0.64, 0.90, respectively. The harvest indexes were 13.8%–26.9%, depending density. Seed positively correlated (r 0.85), branch 0.80), 0.99) which be components plant. Furthermore, no significant correlation found among height, thousand-seed weight, index In conclusion, biomass important trait predict growth models camelina. Also, lower can compensated by greater siliques, branches
