Table 4 The dates that seedlings overcame the water surface, reached maximum height, and started tillering in the planted seedling experiment

From: Establishment strategy of a rare wetland species Sparganium erectum in Korea

Water level Date that seedlings overcome water surface Date that seedlings reach maximum height Date that seedlings start tillering
20 cm 53.0 73.0 85.0
10 cm 42.9 ± 1.5 80.0 ± 6.2a 88.5 ± 3.5a
5 cm 25.0 ± 2.3 70.4 ± 5.2b 58.1 ± 4.4b
0 cm 56.2 ± 2.0c 39.0 ± 1.0c
−5 cm 61.0 ± 0.0bc 47.8 ± 1.1bc
  1. Values are means ± S.D. Different letters in the table indicate significant differences at the 5% level based on Duncan’s test among groups of means. 20 cm water level was excluded from statistical analysis because there was only one sample from that water level
