Pollination takes place immediately before the anthesis. Anthers elevate by elongating the stamen filaments, and untimately they go out the spikelet during anthesis. When anthers touch stigma, some pollen are left on the stigma. The stigma can receive pollen also during the flowering, when the spikelet opens.
Curb weight Curb weight or kerb weight is the total weight of a vehicle with standard equipment, all necessary operating consumables, a full tank of fuel, while not loaded with either passengers or cargo. This definition may differ from definitions used by governmental regulatory agencies or other organizations.
The kerb or curb weight is the weight of the vehicle minus any passengers or cargo. This refers to the weight of the car if it was parked on the curb without anything in it. It still has all the necessary equipment and fuel but doesn't have any added weight that isn't built into the car. The gross weight refers to the car's total weight when it has added passengers and cargo.
