For both species, seedlings were cultivated in four different PVC container-types varying in size ( mL and mL) and shape ([10, 20, 35, and 45] cm in length), and a control treatment that. Seedlings from invigorated and redried seed survived better than seedlings from untreated seed.

Seedlings from the best seed quality had higher values in seedling height, about 35%, shoot length. A controlled experiment, in which plant density was varied independently of container volume, showed that with closer seedling density shoot height increased, but root-collar diameter decreased.

In P. tabul aeformi s but not T. orientalis, there was a significant negative relationship between seedling density and whole plant dry by: 1.

Stems progressively replaced lignotubers as main storage organs as tree size increased. Evidence for a role of water stores in buffering daily water deficits was weak. Leaf water potentials remained above MPa and stomatal conductance below mmol/m2/s, suggesting that gas exchange during the rainy season was limited to prevent xylem.

It is frequently referred to as the South American Ostrich, and also as the resemblance which it bears to the true ostrich is striking, but it may at once be distinguished therefrom by the fact that it has three toes and a feathered head and neck; furthermore, it is smaller in size, and lacks the conspicuous white wing- and tail-plumes.

Thus an emphasis on genera and genus size (e.g. Frodin ) is inappropriate; the proper units of comparison for a genus are its sister taxon and/or other clades of the same age, not other genera (c.f.

Givnish Brocchinia is to be compared with all other Bromeliaceae) - although I do mention genus size on occasion, it is simply the size. Known as Szechuan peppercorns, each berry is about the size of a black peppercorn (an unrelated, tropical vine, Piper nigrum).

The seed is black and is revealed when the berry splits open in the autumn. The seed itself is tasteless but its pink coating (the pericarp) gives a fizzing and numbing sensation in the mouth and on the tongue.

With the secorvd cycle there will be a much lower density of large trees emd a greater density of small and medium-sized trees. This has inportant inplications v^en it is considered that the numbers of many vertebrate species were related to the presence of large trees.
