VARIACIÓN DEL TAMAÑO DE FRUTOS Y SEMILLAS EN SIETE ESPECIES DE ENCINO (Quercus, FAGACEAE)

Abstract

Fresh weight and length and thickness
of fruits and seeds of Q. candicans, Q.
crassipes, Q. germana, Q. greggii, Q.
peduncularis, Q. polymorpha and Q.
xalapensis were studied. The data were
analyzed using a variance test (ANOVA).
Significant differences were detected among
the seven species (P < 0.05) in fresh weight
and length and thickness of seeds, as well
as length and thickness of the fruits, but no
differences were found in fresh weight of the
fruits. Quercus crassipes and Q. xalapensis
show the least variation in weight and size
of fruits and seeds. The average weight (g)
of the fruits and seeds in the different species
was 3.78 and 1.67 in Q. candicans; 2.29 and
1.48 in Q. crassipes, 12.88 and 9.75 in Q.
germana; 1.90 and 1.51 in Q. greggii; 1.12
and 0.88 in Q. peduncularis; 1.67 and 1.16
in Q. polymorpha; and 1.81 and 0.90 in Q.
xalapensis.
