lituratus while defending infructescences
of Cecropia glaziovii Snethl.
In this case, the reduced production of higher-order shoots in CD plants (strong determinants of infructescence
production) compared to CE plants supports the idea that plants under shade show limited reproductive output (Bedetti et ah, 2011).
The number of verticillasters increased as the length of the infructescence
stalk increased (Fig.
Caespitose, stemmed palms; stem heavily armed at the internodes, spines falling with the age; sheaths of the dead leaves not persistent on the stem; spines on the petiole not arranged in parallel rows; infructescence
pendulous; petals of the staminate flower reflexed --Astrocaryum aculeatissimum
This was accomplished by multiplying the mass of harvested infructescences
by the slope of the regression of seed mass on infructescence
Unfortunately, during my two years living and working in Panama (February 1999 to April 2001), I only ever found old infructescences
and one half-eaten pale yellow flower, which is not enough to be certain of their identity.
In the fine-scale analysis of the effect of anthracnose on fruit production, the number of fruits per infructescence
and the proportion of infected subtending leaves were averaged within trees.

3) Finally, artificial damage increased infructescence
abortion for infructescences
produced from the selfed pollination treatment but did not affect infructescences
produced from the outcrossed pollination treatment.
In this study, I examined the annual species, Cosmos bipinnatus (Compositae), testing the hypothesis that sequential flowering enables individuals to compensate for early seed predation by increasing seed production in later infructescences
, increasing infructescence
number, and/or shortening the time needed to produce later infructescences
morphology in Altingia (Altingiaceae) and discordance between morphological and molecular phylogenies.
Seeds have no specialized structures for dispersal, and most fall with the infructescence
, lodging within [approximately]1 m of the adult plant (Inouye and Taylor 1980, Wied 1996).
Spikes in longest infructescence
