Burs were considered to have germinated after one radicle had emerged, although burs may contain more than one
caryopsis.
GA3 is found to control
caryopsis formation in crops (Kende and Zeevaart, 1997; Hansen and Grossman, 2000).
Purple rice is known under local name of Khao Kam (dark colored rice) in Lao PDR (Appa Rao et al., 2006) and northern Thailand, for the dark color of its unpolished brown rice', de-husked
caryopsis, with embryo, pericarp and aleurone still intact, the form normally used.
Nonetheless, AACC has endorsed the following definition: "Whole grains shall consist of the intact, ground, cracked or flaked
caryopsis, whose principal anatomical components--the starchy endosperm, germ and bran--are present in substantially the same proportions as they exist in the intact
caryopsis."

Characterisation and functional analysis of two barley caleosins expressed during barley
caryopsis development.
Photochemical activity in chloroplasts of anthers and
caryopsis in cereals.
The mechanical treatment of pricking the
caryopsis hull once (one side of
caryopsis) or twice (opposite sides of
caryopsis) with a pin was tested to determine if pricking promoted water uptake over time (24, 48, 72, and 96 h) and germination of hulled seed.
Embryo and
caryopsis characters tend to be phylogenetically stable in the grasses.
They also produce a distinctive fruit structure (the grain or
caryopsis) that is unique within flowering plants and has immense agricultural value.
In Table III we see that the
caryopsis (c) which is situated in the terminal spikelet germinates the poorest and the lowest one in the dispersal unit ([a.sub.1]) germinates the best.
The term "chaffy-seed" denotes seed units consisting of a
caryopsis and its subtending appendages (lemma, palea, glumes, hairs, and awns).
