Sampling was performed by means of the collection of
inflorescences in 30 randomly selected plants.
We hypothesized that species richness, abundance, and diversity of Coleoptera in
inflorescences of cultivated species would be lower than in
inflorescences of naturally occurring species.
In Poaceae, the species with reduced
inflorescences often present an important development of floriferous shoots.

The ESTs used in this study were produced with 67 cDNA libraries prepared using
inflorescences (spike at flowering or before flowering, anther, pistil, ovary, palea, and lemma), roots, stems, leaves (including seedlings and crown tissues), and seeds (matured or immature embryos) from normally grown seedlings or plants and represented 434,658 cloning events (Table S1).
In addition, farms in Australia and Costa Rica are cultivating the species and selling its
inflorescences as cut flowers [27].
In most other Pitcairnia species the longer (> 20 cm)
inflorescences lie above the leaves (Smith & Downs, 1974), while the short (ca.
We enclosed a haphazardly-selected
inflorescence on each plant before flowers opened using mesh bagging.
The vase life of the
inflorescences ranged from three to five days, totaling a difference of approximately 26% between control and the worst treatment (48h).
In nearly all cases (except
inflorescences produced per plant in the down treatment in 2004-05 and the average number of fruits produced per
inflorescence in the 2006-07), reproductive output as measured by
inflorescence characteristics and fruit production was lower in the year following the initial planting season (2004-05 versus 2003-04 and also in 2006-07 versus the 2005-06 season).
