Biomechanics of Atlas Cedar Roots in response to the Medium Hydromechanical Characteristics

Table 4

Root penetration rate of cedar seedlings on different media.

Medium	Penetration rate (mm/day)
Hyd	0.661 ± 0.036^a
Ver	0.394 ± 0.051^b
Saw	0.350 ± 0.077^bc
VGr	0.271 ± 0.006^ce
San	0.226 ± 0.010^e

Mean ± SD followed by letters indicates significant differences ( LSD test). The medium acronyms are as designated as in Table 1.
