Table 3 Phenotypic traits of two pea genotypes in RhizoTubes or pots

From: RhizoTubes as a new tool for high throughput imaging of plant root development and architecture: test, comparison with pot grown plants and validation

  Plant dry matter (g/plant) Shoot/root dry matter Mean nodule dry matter (mg/nodule)
Caméor
 Pot 0.43 ± 0.04 (A) 1.478 ± 0.201 (A) 0.222 ± 0.095 (A)
 RhizoTube 0.39 ± 0.03 (A) 1.413 ± 0.202 (A) 0.223 ± 0.065 (A)
Kayanne
 Pot 0.468 ± 0.06 (A) 2.980 ± 0.193 (A) 0.125 ± 0.029 (A)
 RhizoTube 0.422 ± 0.03 (A) 2.599 ± 0.292 (B) 0.118 ± 0.025 (A)
  1. Biomass, shoot over root biomass ratio, nodule over nodulated root biomass ratio and mean nodule weight of two pea genotypes (Cameor, Kayane) cultivated either in RhizoTubes or pots were measured after 18 days since sowing. Different capital letters in parentheses indicate significant differences (P < 0.05) between traits measured in RhizoTube or in pot
