Disclosed is a pollen control dry pollination machine for Abies ziyuanensis, comprising a lever; a side of a top of the lever is fixedly connected with one end of a square tube; another end of the square tube is rotatably connected with a pollination shell; a top of the square tube and a top of the pollination shell are slidably connected with a fan; the pollination shell is internally provided with a pollen box, a pollen outlet cover and a pollination chamber from a top to a bottom in sequence; the pollen box is communicated with the pollen outlet cover; a bottom of the pollination chamber is provided with an opening; an Abies ziyuanensis ovulate strobilus to be pollinated is placed in the pollination chamber; a bottom of the pollination shell is fixedly connected with a rotating opening; the lever is provided with a switch.

The invention provides novel systems and methods for liquid-mediated delivery of pollen to a female reproductive part of a recipient plant. The systems provided herein include a container configured to receive a liquid pollen suspension solution, and an applicator attached to the container configured to spray the liquid pollen suspension solution onto the recipient plant. The methods provided herein include spraying a liquid pollen suspension solution onto at least a first female reproductive part of a recipient plant using the system provided herein, thereby pollinating the recipient plant.

A method of pollinating a plant: flying an unmanned aerial vehicle above the plant and generating a thrust that contacts the plant, that produces a sound pressure level of at least 6×10.sup.−5 Pascal at the plant, and that produces a frequency that induces the plant to release pollen.

An aerial craft and sealed force vectoring flight system is disclosed. The aerial craft includes a main body hull, lift jets, a generator, an electrical re-introduction circuit, a hydraulic pump, air flow compressors, an RPM sensor, a max speed limiter hydraulic draft by-pass valve, and a battery. The electrical re-introduction circuit throttles the generator into high-velocity rotation and yields excess electrical current to then be applied to the lift jets. The hydraulic pump pulls pressurized hydraulic fluid across a preceding hydraulic drive impellor such that the pressurized hydraulic fluid returns to confinement under pneumatic pressure faster than a discharge of hydraulic fluid. The air flow compressors generate electricity that is re-introduced into the lift electric motors. The RPM sensor and max speed limiter hydraulic draft by-pass valve speed regulate the generator. The battery initially powers the generator.

Novel, universal, in-field/in-orchard, well-controlled, scalable, easy-to-use, and cost-effective management systems and methods for artificial pollination of agricultural areas such as orchards and fields are provided.

A pollination control structure comprises a support; a plurality of support fixings, each support fixing being attached to or integral with the support, and; a barrier member comprising a plurality of barrier member pieces. At least one of the barrier member pieces is releasably attached to at least one of the support fixings by an intermediate fixing. The barrier member piece is releasably attached to the intermediate fixing, and the intermediate fixing is releasably attached to the support fixing.

A pollinating device for pollinating crop plants includes a base mountable on a carriage. At least one pollination unit is mounted on the base and includes a pollen-releasing apparatus configured to release pollen from male flowers of the plants and at least one nozzle for directing fluid along a flow path for delivering at least some of the released pollen to the pollen-receiving rows of crop plants. Certain pollinating devices include multiple pollination units spaced apart along a width of the base. Some pollination units include at least two opposing nozzles. Plants are pollinated by driving the carriage along a field and directing air from the nozzles over the pollen born by some plants to deliver the pollen to female flowers of other plants in the field.

A system including means for encapsulating a plant in a closed environment; means for injecting pollen into said closed environment; means for expanding a space covered by said closed environment; means for filtering contaminants from entering said closed environment; means for attaching said closed environment to a plant appendage or plant container; means for holding or diffusing pollen inside said closed environment; and means for maximizing an amount light penetrating within said closed environment.

A method for the determination of pollen viability and/or maturation grade of a pollen population, comprising mechanically removing pollen grains from flowers; re-suspending pollen grains in an electrically conductive buffer for keeping the plant cells to remain viable; passing the pollen suspension through an appropriate filter with a pore size suitable for a microfluidic device being adapted to perform impedance flow cytometry (IFC); An advantage of the present invention is that a plant cell does not have to be stained for viability analysis, the method is non-invasive and a high number of cells can be analyzed in a short time frame in real-time and on-site. It is possible to follow developmental processes of plant cells, and that it is applicable to all plant species. In particular, the method allows a standardized measurement independent of the location and all over the world.

An indoor gardening appliance includes a liner defining a grow chamber and a grow module rotatably mounted within the grow chamber and defining a plurality of apertures for receiving a plurality of plant pods. A pollen pod is mounted to the grow module in one of the apertures and contains pollen for pollinating the plant pods to facilitate plant growth. A pollen ejection device, which may be a pressurized air nozzle or a protruding member for puncturing the pollen pod, is fixed to the liner or otherwise stationary relative to the pollen pod and is configured for engaging the pollen pod when the grow module rotates the pollen pod past the pollen ejection device to discharge and disperse pollen onto the plant pods.
