(Myrtaceae), with particular reference to schizogenous
These air spaces are generated either with (lysigenous) or without (schizogenous
) cell death.
The three families differ from Apiineae in several structural features, including the lack of schizogenous
secretory canals (see Plunkett & Lowry, 2001) and their pollen exine texturing, which is usually reticulate in most Apiineae but varies in the three remaining families (Karehed, 2003).
Stover [3, 4] also illustrated an aerenchyma with schizogenous
and lysigenous cortex, but with no enlarged outermost mid-cortex layer, while Jorgenson et al.
It presented very abundant large schizogenous secretory cavities situated externally to the phloem (at one time described as laticiferous vessels).
It presented large schizogenous secretory cavities situated external to the phloem (Fig.
They presented few schizogenous secretory cavities situated external to the phloem.
We presume that the mucilage canals have a schizogenous
This swelling caused the schizogenous secretory cavities of lemon to appear lysigenous.
Although Frank (1868) found schizogenous development in most species, he did report apparent resorption of cells in secretory ducts of Angiopteris and Tilia.
