These stimuli were colorimetric metamers
, but they were not visual metamers
to real human observers.
P}} where S is the set of buds (nonterminal elements) and M is the set of metamers (terminal elements).
The recursive equations for the moments of the numbers of metamers are finally deduced.
However, we can distinguish two types of metamers along the stem.
In Abutilon, neighbor identity had no effect on above-ground biomass, number of main axis nodes, maximum internode length, petiole length, area per leaf, and metamer mass, or specific masses of stems, petioles, or leaves (0.
Petiole leaf inclination angles of both Abutilon and Polygonum followed a regular pattern with metamer age, and were generally unaffected by neighbor identity.
In all target species plant aboveground biomass, and within-plant maximum internode and metamer mass, were the most variable characters (among individual plants) measured (Table 4).
Thus, plants do not merely increase in size (biomass, height, volume) during ontogeny by adding metamers, but these metamers almost universally show a certain degree of variation, in part simply because an increase in size necessitates correlated changes in shape and geometry (Niklas, 1994).
In this paper, we include Philipson's and Ray's refinements, but otherwise use "heteroblasty" similar to Goebel's original definition as a "rather sudden and substantial change in form of individual metamers or plant habit during ontogeny".
So, for instance, generative cells constitute the meristem, which produces metamers, which together make up modules.
The metamer is defined as the internode, upper node, attached leaf, and axillary bud(s) (Barlow, 1989), and metamerism (White, 1984) is the serial repetition of metamers within or along an organism.
Metamers, in their various modifications, are organized into repeating units, and these determine the aspect and organization of the shoot system.
