Geometrical Relationships Specifying the Phyllotactic ...
Different spiral phyllotaxes are illustrated by the apical meristems of Brassica
oleracea, Linum usitatissimum, Helianthus annuuss, which show that the ratio of
the size of young primordia to the apical dome is inversely correlated with the ...

Phyllotaxis: A Systemic Study in Plant Morphogenesis
(1) Built with d = 1", a noble number, the decrease of the rise r does not change
the shape of the Voronoi polygon, but only its size and orientation, while the
system rises from (2, 3) to (5, 3) to (5, 8) phyllotaxes. (2) The lattice is built with d
= J ...

Functional Plant Ecology, Second Edition
Most of the phyllotaxes shown in Figure 4.1 were represented, and leaf size
ranged from a few to several hundred square centimeters. Light harvesting
efficiency was calculated with the three- dimensional plant architecture model
YPLANT ...

The Natural History of Plants: Their Forms, Growth, ...
The observation already alluded to above, according to which those fractions by
which the phyllotaxes actually found in plants may be expressed as members of
a definite series, must now be considered further. It has been found that the ...

American journal of botany
In Michelia' s range of phyllotaxes. only the 3/8 system is a member of the
Fibonacci series, the common type in vegetative shoots. The 2/7, 3/7, and 4 10
systems of other flowers from the same tree belong to other series, and are
supposedly ...
The prime whorls could not give rise to any of the known Phyllotaxes of alternate-
leaved plants ; but the whorls of powers of 2 may do so as follows : — (1.) The
whorl of 2, by suppression of the alternate whorls, gives the phyllotaxis = J.

A New Twist to Fourier Transforms
It is given in complex form by t Bz Ct jSt 0 expjpx2a2 where C(t) and S(t) are the
Fresnel cosine and sine integrals respectively. Daisy [1, p. 397], phyllotaxes
describe the arrangement of flower petals [1, p. 1355], that are much too
numerous to ...

A Text-Book of Botany: Morphological and Physiological
This observation is of interest so far as it makes it seem doubtful whether certain
complicated phyllotaxes are always due to the original arrangement of the
members 1. (4) It must be observed whether the position of newly-formed
members or ...
