Table 1 Effect of sand burial depth on the emergence process of X. spinosum seeds

From: Effects of sand burial depth on Xanthium spinosum seed germination and seedling growth

Sand burial depth (cm) Seeding emergence initiation time (d) Seeding emergence peak time (d)
1 5 ± 0.05d 6 ± 0.10d
2 8 ± 0.13ab 10 ± 0.47ab
3 6 ± 0.15c 8 ± 0.14c
5 8 ± 0.22b 10 ± 0.52b
7 11 ± 0.55a 13 ± 0.22a
9 22 ± 0.51a 22 ± 0.00a
