Growth of atlantic white cedar in response to substrate and fertilizer source when grown in containers of varying volume. (A) Height , (B) stem diameter, (C) root dry weight, (D) shoot dry weight, (E) total dry weight. (●) Polyon, (❍) Osmocote, (-----) NCFS substrate, (------) 3 bark : 1 peat substrate. Means are in original units; SE = standard error of the mean; asterisk indicates the SE after a squareroot transformation; n = 18.

... up to a larger container always signifi cantly increased plant dry weight (Table 1, Fig. 2); the most notable change occurred when volume went from 98 cm 3 (Ropaks) to 164 cm 3 (Super Cells). Additional increases in volume were accompanied by a linear increase in plant height and dry weight. The most uniform plants, for both substrates and CRFs, grew in Super Cells (164 cm 3 ) and Deepots (262 cm 3 ...

... and stem diameter were affected by all variables except irrigation regime (Table 1). Maximum height was 32 cm (V530 tray, Osmocote, NCFS substrate); the minimum 12 cm (Ropaks, Polyon, bark substrate). The container × fertilizer interaction was most evident in Super Cells, as Osmocote plants were 30% taller than Polyon plants (26 vs. 20 cm) ( Fig. 2A). Stem diameters were largest for the NCFS substrate amended with Osmocote (Fig. 2B). Average maximum and minimum diameter was 3.7 mm (V530 tray, NCFS mix, Osmocote) and 1.6 mm (Ropaks, bark mix, Polyon), ...

In addition, the NCFS substrate yielded larger plants than the bark substrate, with the difference most evident in the larger containers (V530 and Deepot) (Fig. 2).

... grew best in the NCFS substrate (Fig. 2). The high peat content and water hold- ing capacity was more representative of the native soils, and likely resulted in the increased growth (Greenwood, 1994). The 3 bark : 1 peat substrate (88% porosity and 27% air space) yielded 21% lower dry weights, consistent with earlier experiments that yielded decreases of 22% in total plant ...
