Seed
Abbreviation: RAOC
Seed sample from: 2011
Average Measurement: 3.5 x 2.6 x 1
Features
Shape: Seed surface is rounded, tapering off to a style that is opposite hilum, but off centered from it.
Additional structures: Style generally 1 – 2 mm long.
Color: Seeds are brown, tending toward a lighter brown or tan at edges of seed surface.
Surface: Seeds are papillose with some small ridges around the surface edges.
Latitudinal Cross Section: elliptical
Longitudinal Cross Section: elliptical
Basic Explanations and Assumptions:
The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.
Measurements included are the mean average for each measurement of ten separate seeds.
All measurements in millimeters unless otherwise noted.
