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.
In fact, half-ton pickups weigh much more than that. The weight of a truck without cargo or passengers is called the curb weight. For example, many 2007 half-ton pickups have curb weights between 9000 (4082.3 kg) and 11000 (4989.5 kg) pounds [source: Edmunds ].The half-ton description loosely refers to the truck's payload capacity.his means that the truck can carry up to 1000 pounds (453.5 kg) of cargo and passengers in the cab and bed. But wait a minute: If you take a look at the stats on modern half-ton pickups, you'll notice that their payload capacities exceed 1000 pounds (453.5 kg).
