INTERACTION EFFECT OF TEMPERATURE AND CARBON
The combination of increased temperature and increased carbon dioxide
predicted in all climate change scenarios suggests that for some species
the growth stimulation may be greater than the 40-50%. The doubling of
carbon dioxide concentration combined with a 3 °C increase in tempera-
ture could lead to 56% stimulation in growth.

POTENTIAL OF CROP IN CARBON SEQUESTRATION
Carbon sequestration plays an important role in the global carbon cycle.
Green plants remove (sequester) carbon from the atmosphere through
photosynthesis. They extract carbon dioxide from the air, separating the
carbon and oxygen atoms, returning oxygen to the atmosphere, and using
the carbon to make biomass in the form of roots, stems, and foliage. The
tablebelow has shown different temperate fruit crop potential as sequesters
(Table 3.2).
