Fig. 4From: RhizoTubes as a new tool for high throughput imaging of plant root development and architecture: test, comparison with pot grown plants and validationRoot architecture phenotypic traits Pisum sativum (Kayanne genotype) grown for 28 days in pots (open circle) or RhizoTubes (closed circles) with 10 meq soil nitrogen: number of lateral root (a); root (b); number of secondary roots (c); length of longest secondary roots (d). Data are given as the mean ± SE (n = 4). Asterisks indicate significant differences between traits measured in RhizoTube or in pot for P < 0.05Back to article page
