Use Stomatal Density when you need to compute stomatal density in stomata per square millimetre as the counted stomata divided by the microscopic field area. Enter Stomata counted and Field area using the definitions and units below so the result can be reproduced.

Stomata counted

An integer count or setting greater than or equal to 0, expressed in stomata.

Field area

A finite measured or assumed value, expressed in mm².

The published tool contract uses this rule: Compute stomatal density in stomata per square millimetre as the counted stomata divided by the microscopic field area.

Stomatal density

The calculated stomatal density in stomata/mm².

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.

Retain the original Stomata counted and Field area values and their units alongside the result. Seeding Density is useful when you instead need to compute cell seeding density in cells per square centimeter from a cell count and growth area. Root Length Density provides another view by helping you compute root length density RLD in centimetres per cubic centimetre of soil as root length divided by soil core volume.

• Seeding Density

  Compute cell seeding density in cells per square centimeter from a cell count and growth area.

• Root Length Density

  Compute root length density RLD in centimetres per cubic centimetre of soil as root length divided by soil core volume.

• Stem Wood Density

  Compute stem wood density in grams per cubic centimetre as oven-dry stem mass divided by stem volume.
