Inflorescence of Kentucky bluegrass

Poa pratensis L.

The inflorescence of Kentucky bluegrass is a panicle, the parameters of which are used as key morphological traits in variety testing and seed identification.

In the reference 21 varieties crop Kentucky bluegrass, where this is mentioned in the description.

The inflorescence of Kentucky bluegrass is a panicle, ranging in shape from spreading to pyramidal or oblong. When describing a variety, the panicle length (up to 20–25 cm), the number of branches in the lower whorl (usually 3–5) and their surface texture, as well as the size of the spikelets (3.5–6 mm) and the number of florets within them (2–5) are recorded. An important phenological trait is the time of anthesis initiation.

In seed production, the structure of the inflorescence and the density of spikelet placement affect the threshing and seed cleaning processes. Due to the small size of the seeds and the pubescence of the glumes, which tend to clump, specific material preparation techniques are required. The intensity of inflorescence formation depends on seeding density and plant development conditions, although for turf use, these parameters are considered secondary due to regular mowing.
