Area from image analyses accurately estimates dry-weight biomass of juvenile tissue from the moss Ceratodon purpureus.

ABSTRACT:

Premise

Mosses have long served as models for studying many areas of plant biology. Investigators have used two-dimensional measurements of juvenile growth from photographs as a surrogate for dry-weight biomass. The relationship between area and biomass, however, has not been critically evaluated.

Methods

Here we grew axenic tissue cultures of 10 Ceratodon purpureus isolates to study the relationship between these parameters. We measured area and biomass on replicate cultures with two distinct starting inoculum sizes each week for three weeks. We then examined the correlation between area and biomass as well as the influence of variation in inoculum size on both parameters.

Results

We found a strong correlation between area and biomass after two weeks of growth
