Problems solved by technology

This configuration is very detrimental to pollen viability when the pollen is of the "recalcitrant" type
[0014] In addition, the passage section formed by the annular driving air injection pipe is much larger than that of the suction pipe at the height of the Venturi system, so it cannot provide the function of amplifying the ratio of driving air to the incoming air flow

Embodiment Construction

[0060] Such as figure 1 The illustrated air moving device 10 is configured to pollinate at least one recipient plant using pollen collected from at least one donor plant. The collected pollen is preferably of the "recalcitrant" type, eg pollen of wheat (triticum sp.), barley (hordeum sp.), rice (oryza sp.) or maize (zea mays sp.).

[0061] The air moving device 10 comprises means 12 for collecting pollen from said at least one donor plant. Herein, pollen interchangeably means a pollen grain or a plurality of pollen grains. The collection device 12 is configured to accommodate donor plants inside the collection device during use of the air moving device 10 . The air moving device 10 also includes means 14 for distributing pollen collected from a donor plant onto at least one recipient plant. In a similar manner to the collection device 12, the distribution device 14 is configured to accommodate the at least one recipient plant inside the distribution device during use of the...

Abstract

The invention relates to an air-moving device (10) for pollinating at least one recipient plant using pollen collected on at least one donor plant, comprising: - means for collecting (12) the pollen from the at least one donor plant, - means for distributing (14) the pollen on at least one recipient plant, - a channel for conveying the pollen collected from the collecting means (12) to the distributing means (14), - an air flow amplifier (18) which employs Coanda effect for inducing a flow of air inside the conveying channel from the means for collecting (12) the pollen to the means for distributing (14) the pollen. The invention also relates to a pneumatic device for diverting the pollen flow which employs Coanda effect and is provided at the means for distributing (14) the pollen.

Description

technical field [0001] The present invention relates to an air moving device for pollinating a recipient plant using pollen collected from a donor plant. The invention relates in particular to a device comprising a Coanda effect airflow amplifier (also known as an "air amplifier" or "air mover"). The invention also relates to a pneumatic deflector for deflecting the Coanda effect flow of pollen arranged at the level of the pollen distribution device. [0002] The invention also relates to a device and a vehicle comprising such an air moving device. Background technique [0003] In the field of plant reproduction, plants are pollinated by the transfer of male gametes (pollen) to the female recipient members of the plant (stigmas). This transfer can be accomplished by wind, in which case the plants are known as wind-pollinated plants. [0004] For some crops, natural pollination under natural conditions may prove impossible or more often insufficient, thus leading to recour...
