Stone pine (Pinus Pinea L.) is a multi-purpose species for Mediterranean
forestry owing to both economic and socio-economic importance. Thus, in
this study the effects of magnetic field on the germination of seeds
and growth of seedlings of stone pine were investigated. For this
purpose, its seeds were treated by a magnetic field of 9.42 mT for a
different period of time – 0 min (control), 15 min, 30 min and 40 min in
a cylindrical shaped sample, made of a nonmagnetic thin transparent
plastic sheet. Germination experiments were conducted in the greenhouse
of Bart?n University. Considered the germination results as a whole,
while seeds exposed to a magnetic field for 30 and 45 minutes resulted
in higher germination energy (43%) and percentage (55%), respectively.
Both the lowest germination energy (6%) and germination percentage (32%)
were found out to be in the seeds without applying magnetic field.
Magnetic field increased shoot height, root collar diameter and also tap
root length of stone pine seedlings. In terms of shoot height, 85% of
1+0 seedlings was proper for afforestation activities based the
classification of TSI. Moreover, magnetic field treatments may be
considered as an alternative method to enhance germination Stone pine
seeds and to obtain better growth characteristics of their seedlings.
This study is important in terms of determining the effects of magnetic
field on the germination of seeds and growth of seedlings of forest tree
