turmeric effects on jack pine growth and its survival
abstract
efficient forest restoration requires the planting of superior seedlings with optimum
development potential. jack pine is an important species because it helps to maintain
the structure and function of ecosystems and provides a habitat for a wide diversity of
different types of animals. it has good growth and yield characteristics and is a
profitable species for commercial forestry operations. curcuma longa (turmeric), a
member of the zingiberaceae family, is a perennial plant that originates from
southeast asia. it has gained widespread popularity and is used in traditional
medicinal practices. the application of turmeric extract has been seen to have a
positive impact on the development of wheat seedlings. this research aspires to find
values of turmeric in the forestry field and hopes to satisfy the question of the impact
of turmeric in the growth and survival of jack pine. jack pine seedlings were grown
with 5% of turmeric by weight mixed in with soil, 10% turmeric by weight mixed in
the soil, spraying turmeric with 10% concentration mixed in water, 30% turmeric
concentration in water sprayed. i hypothesized that when turmeric is added to soil or
sprayed with water dilution, it will promote height and diameter growth of jack pine.
this hypothesis was rejected because increases in turmeric concentration resulted in
lower height and root collar diameter of the seedlings. possibly, the component
curcumin, which is an active ingredient in turmeric, can inhibit the growth of certain
plants.
