Reproductive meristem
-
In angiosperms the transition to flowering is controlled by a complex set of interacting networks integrating a range of developmental, physiological, and environmental factors optimizing transition time for maximal reproductive efficiency.

Perenniality is best understood in quantitative terms, involving the relationship between production vs. turnover of meristems, biomass, or energy reserves. Previous quantitative trait locus (QTL) studies using divergent populations of the perennial rock cress Arabidopsis lyrata have shown that trade-offs in vegetative growth vs. reproduction are due to cascading effects of differences in early vegetative development, which contribute to local adaptation.

The transition from vegetative to floral state in shoot apical meristems (SAM) is a key event in plant development and is of crucial importance for reproductive success. In perennial plants, this event is recurrent during tree life and subject to both within-tree and between-years heterogeneity.

Geophytes possess specialized storage organs - bulbs, tubers, corms or rhizomes, which allow their survival during unfovarable periods and provide energy support for sprouting and sexual and vegetative reproduction.

Red firespike (Odontonema strictum) is a tropical flowering plant that has a potential as a new flowering potted plants for its attractive red inflorescence. Flowering and morphology of red firespike were evaluated in response to photoperiod. In Expt. 1, morphology and growth characteristics of firespike were evaluated in response to photoperiod. Plants were propagated from semi-softwood cuttings and grown under long days (LD). Plants were exposed to short days (SD) of 9 h for 0, 4, 8, 12, 16, 20, 24, 28 or 32 days. Plant height and growth index increased as the number of SD increased.
