Inflorescence of red top (black bent)

Agrostis gigantea Roth

The inflorescence of red top (Agrostis gigantea) is a loose, pyramidal panicle ranging from 7 to 30 cm in length. Its morphological features, including the greenish to reddish color of the spikelets, are key species-specific traits for crop identification.

In the reference 3 varieties crop Black bent, where this is mentioned in the description.

The red top panicle is highly branched with scabrous (rough) branchlets arranged in whorls. During anthesis, the inflorescence becomes spreading, although the branchlets contract at other times. The small, 2–3 mm, single-flowered spikelets exhibit a specific coloration ranging from greenish to brownish-purple or reddish, which determines the visual appearance of the generative shoots.

In variety testing and agronomy, inflorescence morphology serves as a crucial diagnostic trait for distinguishing red top from other species, such as creeping bentgrass (Agrostis stolonifera). This trait is evaluated comprehensively based on panicle length, shape, and density, as these characteristics influence seed productivity and the crop's biological cycle.
