Answer 5

Spikelet: a flowering unit comprised of one or more florets enclosed by two glumes (bracts). When the spikelets are attached directly to the rachis the inflorescence is called a spike (wheat, rye, barley, ryegrass). When the spikelets are attached to the rachis with short pedicels, the inflorescence is termed as raceme. When the spikelets are attached by means of a branch the inflorescence is said to be a panicle.

Answer 12

The spikelet meristem gives rise to a single floral meristem and a single floret . By
comparison, the inflorescence, or spike, of , for example , a barley (Hordeum vulgare) and wheat (Triticum aestivum) is unbranched. In barley, the inflorescence meristem is indeterminate and produces lateral spikelet meristems that form three florets. In wheat, the inflorescence meristem is determinate and produces a limited number of lateral spikelet meristems and a terminal spikelet meristem, with each spikelet meristem producing multiple florets.

Answer 13

ohk got it!!! thanks a lot!!!

Answer 14

Also, In an unbranched inflorescence, known as a spike, axillary meristems produced by the inflorescence meristem develop directly into spikelets. As with wheat and barley, the inflorescence of Brachypodium (Brachypodium distachyon) is a spike !
