3.7.3. Flowering order of a panicle
As the lemma and palea open and the anthers protrude, the shedding of the pollen grains immediately follows. It takes about 7 days for all of the spikelets in a panicle to open. The upper spikelets ( number 1 ) open first. The lower spikelets open last. They usually do not completely fill in large panicle. Modern varieties have 100-120 spikelets per panicle.
