Table 1 The growth parameters of Brassica napus plantlets cultured under nitrate treatment

From: Implication of quantifying nitrate utilization and CO2 assimilation of Brassica napus plantlets in vitro under variable ammonium/nitrate ratios

Parameters NO3-N(mM) (+ 20 mM NH4-N)
5 10 20 40
Increased biomass (g) 1.97 ± 0.26b 2.87 ± 0.25b 3.04 ± 0.28ab 4.20 ± 0.31a
Leaf biomass (g) 0.42 ± 0.05c 0.73 ± 0.06bc 0.89 ± 0.09ab 1.18 ± 0.07a
Number of shoots 4.7 ± 0.3b 7.3 ± 0.3a 7.3 ± 0.7a 7.7 ± 0.3a
  1. Each nitrate treatment contained 20 mM ammonium. Each value represents the mean ± SE (n = 3). Values signed with the same letter in each line are not significantly different by Tukey’s test (p > 0.05)
