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 .
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).
