The metabolite levels are also consistent from passage to passage which is expected given the similar levels of viability and cell growth observed (Fig. 4).
At 15 days old, the majority of spore primordia tested positive for viability and the level of viability remained unchanged throughout the spore maturation period 15-900 days old).
Cell growth inhibition was expressed as 50% inhibition of cell viability, which is halfway between the level of viability in the absence of toxin and that in the presence of cycloheximide.
The cells were observed to have populated the scaffold with a high cell density and a high level of viability.
On day 3, the cells showed a significantly higher level of viability on the GAL-PDMS than on the pristine and collagen-coated PDMS.
The level of pollen viability and germination ability differed significantly among the species.
The dose of catalase used here had little effect on the level of cell viability and mutant fraction in control cells.
In support of the latter hypothesis, controlled mating experiments have found no evidence of inbreeding depression at the level of seed viability and fruit set in, respectively, the outcrossing morph of Madagascan B. occultum (U. Jaros, unpubl. data) and neotropical Bulbophyllum species [ 95].
