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.
Subtracting the curb weight of a truck from its published GVWR yields a number that represents the total safe weight of all of the cargo, passengers, tools and other items the truck can carry. Payload capacity is not to be confused with towing capacity, which is usually higher and refers to the amount of weight that can safely be hauled on a trailer.
