Seed

Lupinus bicolor

Abbreviation: LUBI

Seed sample from: 2011

Average Measurement: 2.4 x 1.9 x 0.9

Features

Color: Seeds mostly brown, speckled with brown, gray, off-white, and/ or black. Seeds have distinctive black splotchy line that crosses the lateral seed face to encircle the hilum, inside of which is another similar white line. Seed edges are less heavily speckled with dark colors, giving them a more off-white appearance.

Surface: Seed surface smooth and glossy, with some small concave pockets.

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.
