1. An air-moving device for pollinating at least one recipient plant using pollen collected on at least one donor plant, comprising:
a collecting means for collecting pollen from said at least one donor plant,
a distributing means for distributing pollen on at least one recipient plant,
a conveying channel for conveying the pollen collected from the collecting means to the distributing means,
an air flow amplifier, forming a part of said conveying channel which employs Coanda effect for inducing a flow of air inside the conveying channel from the means for collecting the pollen to the means for distributing the pollen,
wherein the conveying channel has a pollen passage section, wherein variation of the pollen passage section between the collecting means and the distributing means is equal to or less than 30% of the pollen passage between a smallest passage section and a largest passage section of the conveying channel.
