Adaptation
Alfalfa has adapted to the land’s harsh
environment by growing elongated roots (fifteen plus feet). These roots can
reach water sources farther down than many other plants; making it more
resistant to droughts.
It also gives alfalfa its lush green color.
Alfalfa
is very interesting in the fact that it has been genetically engineered for
years to adapt better in different regions. A great example of
this is a strand of alfalfa that is leaf hopper resistant. The resistant alfalfa
has developed small hair-like structures on their stems making it nearly
impossible for the leaf hopper insects to hang on to the plant and feed. This
small genetically infused adaptation has created a colossal difference in the
quality and quantity of alfalfa. Also, the leaves of alfalfa are trifoliate increasing
the surface area for sunlight.
