Question

Talking to plants makes them grow especially if you ‘re a woman according to an experiment by the Ryal  Horticultural Society(RHS皇家园艺学会).

Women gardeners’ voices speed up growth of tomato plants much more than men’s it found.

In an experiment that ran over a month they found that tomato plants grew up  two inches taller if they were serenaded by the sweet tones of a female rather tha a male.

Appropriately the most effective talk came from Sarah Darwin whose great-great grandfather was legendary botanist(植物学家)Charles Darwin one of the founding fathers of the RHS’ Scientific Committee. She read a passage from On the Orgin of Species and beat nine other”voices”.

Her plant grew nearly two inches taller than the best performing male and half an inch higher than her nearest competitor.

The experment began in Apirl 2009 at RHS Garden Wisley in Surrey. A variety of recorded voices were picked to play to 10 taomato plants over a month. Every plant was played a voice through headphones connected to the plant pot and the conditions for all the plants remained the same throughout the experiment. To ensure the experiment was fair two control plants were also left to grow in silence.

The results showed that women on average saw their plants rise by an inch on their male competitors. Some men were so bad that their plants actually grew less than a plant that was left completely alone.

Colin Crosbie the leader at RHS said:”We’re not sure why the female voice is more effecitive It could be that they have a greater range of pitch and tone that affects the sound waves that hit the plant. Sound waves are an emvironmental effect just like rain or light.”
