Table 5 A comparison of two different surfactants, at five concentrations, on transient gene expression of GUSPlus.

From: A high-throughput transient gene expression system for switchgrass (Panicum virgatum L.) seedlings

Conc., % LI700 Silwet L77 Combined
  GUS- positive seedlings, n† GUS- positive seedlings, % GUS- positive seedlings, n† GUS- positive seedlings, % GUS- positive seedlings, mean ± SE
0.0 87 43.5 89 44.5 22.0 ± 0.8a
0.01 93 46.5 97 48.5 23.7 ± 0.5a
0.02 116 58.0 99 49.5 26.9 ± 1.4a
0.04 68 34.0 87 43.5 19.3 ± 1.6b
0.10 19 9.5 16 8.0 4.4 ± 0.8c
  1. Conc. = concentration.
  2. There were no significant differences between surfactants, but there were significant differences between the concentrations of surfactants.
  3. *Three replicates of 50 seedlings per replicate were tested in each treatment.
  4. † Means followed by the same letter (a, b, c) were not significantly different at the 5% level as determined by The Tukey multiple comparison test.
