Purity

Pure seed definition:
AOSA:
PSU#38 – Intact utricle with or without perianth, whether or not
a seed is present. Piece of broken utricle larger than one-half
the original size, unless no seed is present. Seed with or
without seed coat.
Lab notes: Calyx
may persist, covering the seed. Seed is often brittle and
empty. Samples often contain many empty floral parts, which can
be easily confused with pure seed units.
Average pure
seed units per gram:
1,097 seeds per gram (based on AOSA pure seed units only from 4
samples received for testing from 1997 to 2002).
Range of
percent pure seed: 20%
to 41%
Range of
percent inert:
58% to 79%
