植物也有“裙带关系”?
We humans are known to help out members of our own families.
When it comes to business we call it nepotism. Now plants
have demonstrated the same predilection, in a study published
in the American Journal of Botany.
Previous research showed that plants-in that study they used
a plant called the Great Lakes sea rocket-can recognize the
root systems of siblings from the same momma plant and will
give them a more fair share of nutrients in the soil.
This new study is the first to look above ground. Researchers
at McMaster University in Canada potted North American impatiens.
When the plants shared a pot with seeds from the same parent
plant, they shared access to light by growing taller with more
branches and fewer leaves. But when those same impatiens were
planted with other impatiens-but not their siblings-they put
more energy into growing more and larger leaves that could crowd
out the nonrelatives.
Researchers say the roots alert plants to the relationship of
nearby plants, because when impatiens were planted near siblings
but in separate pots, they didn't recognize their kin. Just goes
to show that even in the plant world, family comes first.
