Fortune, P.M., Schierenbeck, K.A., Ainouche, A.K., Jacquemin, J., Wendel, J.F., Ainouche, M.L. Generally, the seedhead has no leaves. Leaf-produced floral signals. The existence of compound inflorescences is not in itself a problem. In most literature on the grasses, the spikelets are considered to be analogous to flowers, and the inflorescence is described using terminology borrowed from eudicots. pp 25-38 | Komatsu, M., Chujo, A., Nagato, Y., Shimamoto, K., Kyozuka, J.

Gallavotti, A., Yang, Y., Schmidt, R.J., Jackson, D. 2008. Komiya, R., Ikegami, A., Tamaki, S., Yokoi, S., Shimamoto, K. 2008. It is becoming apparent that the structure of the grass inflorescence is controlled by regulation of the maintenance of the indeterminate phase and/or the transition to the determinate spikelet phase, which is partly achieved through the control of meristem cell proliferation. A spikelet is subtended by a pair of suppressed leaves called glumes. Kellogg, E.A. The spikelet is a unique structure of inflorescence in grasses that generates one to many flowers depending on its determinate or indeterminate meristem activity. Stapleton, C.M.A. FIGURE 1. Reinheimer, R., Vegetti, A.C. 2008. The origin of the naked grains of maize. Reproductive morphology of the early-divergent grass. 2006. 1A). An indeterminate inflorescence may be a raceme, panicle, spike, catkin, corymb, umbel, spadix, or head. In a raceme a flower develops at the upper angle (axil) between the stem and branch of each leaf along a long, unbranched axis. 2011.

Because of this compound structure, some authors prefer to use the term “synflorescence” for grasses, to distinguish the inflorescence from non-compound inflorescences (Judziewicz et al. Satoh-Nagasawa, N., Nagasawa, N., Malcomber, S., Sakai, H., Jackson, D. 2006. There are two parts to a grass leaf. Mechanisms of floral induction in grasses: something borrowed, something new. Ann. Grass Weeds - Part 1 - Duration: 8:39. The shoot apical meristem of grasses produces the primary branches of the inflorescence, controlling inflorescence architecture and hence seed production. FRIZZY PANICLE is required to prevent the formation of axillary meristems and to establish floral meristem identity in rice spikelets.

Reinheimer, R., Zuloaga, F.O., Vegetti, A.C., Pozner, R. 2009. By definition a grass spikelet is the unit of the inflorscence of a grass, a member of the Poaceae or Gramineae family of plants. Sci. Grass architecture: genetic and environmental control of branching. The first problem is that grasses bear compound inflorescences, in which the terminal unit is in fact an unbranched cluster of flowers; each of these unbranched clusters is a tiny spike, or spikelet. 2012. 9: e1003604.
