In that case, it produces a new metamer with lateral buds ([F.
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 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).
In all target species there was a positive relationship between specific petiole mass and leaf biomass within metamers.
All of these concepts--module, submodule, and SGU--have a more serious deficiency: the repeating sequences of metamers may be different at different places on a shoot, or on different shoots, and the sequences themselves may be organized into sequences.
A definition that allows for comparison among all types of shoots must account for the different variables contributing to their growth: that growth is repetitive; that the repetitive patterns are often independent of external phenomena; that plants are constructed from metamers that may be dissimilar from other metamers on the same axis and from metamers on different axes or plants; and that metamers may be organized into sequences of different orders.
Any sequence of metamers within a RGU that does not include all possible sequences in that RGU is a subsequence (SS).
This definition is free from temporal constraints, it will allow metamers to exhibit great modification, and it will enable comparisons to be made among sequences.
For every given species, then, one can define the RGU in terms of the kinds of metamers produced by the meristem and by the sequence in which they are produced.
Sylleptic buds are those buds that continue development while the RGU on which they are formed is still completing development itself: that is, before the complete sequence of metamers has been produced.
