In addition to surveys of insects on the inflorescences
, monthly ant surveys were conducted throughout the experiment, both to verify that ant exclusion treatments were working and to determine any temporal changes in ant activity at the study site.
In addition, farms in Australia and Costa Rica are cultivating the species and selling its inflorescences
as cut flowers .
completed their development within three to four weeks and by mid-January the population flowering season had started.
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).
Cyperaceae show a significant variation in the structure of their inflorescences
(Haines & Lye, 1983, Goetghebeur, 1998; Vegetti, 2003; Reutemann et al.
Not all plants formed inflorescences
during either of these first two seasons.
It was collected with numerous inflorescences
from each plant (15 per cultivar) were analysed for pigment identification at four different stages within eight weeks.
After obtaining plant height, number of inflorescences
and total dry matter of clippings, it was possible to calculate the percentage of reduction of the respective variable using the equation R (%) = [([V.
2], AF), weight of fresh inflorescences
(g, PFFL), weight of dried inflorescences
(g, PSFL), stem fresh weight (g, PFC), stem dry weight (g, PSC), fresh weight of leaves (g, PFF), weight of dried leaves (g, PSF), and total flavonoid content (%, TTF).
In Brazil, information on the occurrence of Myxomycetes in inflorescences
is scarce and dispersed in the literature (Cavalcanti and Mobin, 2004; Ferreira and Cavalcanti, 2010; Hochgesand and Gottsberger, 1996; Silva and Cavalcanti, 2010), and only Maimoni-Rodella and Cavalcanti (2006) deal specifically with the subject, recording the occurrence of five species in living plants of Hedychium coronarium J.
