What's the difference between caryopses and caryopsis?

Caryopses

Definition:

Example Sentences:

(1) Blocks of embedded caryopses were sectioned, exposing the endosperm tissue, and stained with iodine potassium iodide (IKI) and Calcofluor White.
(2) Methods have been developed for the isolation of aleurone protoplasts from developing caryopses of Hordeum vulgare and Triticum aestivum in order to study transient expression of introduced genes.
(3) Plants, arising from irradiated (300 kR) caryopses of wheat, exhibit a low incorporation of [3H]thymidine into the DNA, which, as shown by sedimentation on sucrose gradients, does not indicate tendencies of normalization.
(4) A staining technique for differentiating starch granules and cell walls was developed for computer-assisted studies of starch granule distribution in cells of wheat (Triticum aestivum L.) caryopses.
(5) The effect of space flight factors, particularly radiation, on Artemia salina cysts, tobacco and rice seeds (embryos and caryopses) was investigated.
(6) Swelling of caryopses of high germinative power was accompanied by activation of the system glycolysis--Krebs cycle--respiratory chain and increase in the level of oxidation--phosphorylation coupling.

Definition:

(n.) A one-celled, dry, indehiscent fruit, with a thin membranous pericarp, adhering closely to the seed, so that fruit and seed are incorporated in one body, forming a single grain, as of wheat, barley, etc.

Example Sentences:

(1) Cytochemical changes during the early development of maize caryopsis are reported.
(2) GAD activity and gamma-ABA content of wheat embryos at 7 ripening stages were verified with the aim of studying the metabolic activity of embryo during dehydration and quiescence of caryopsis.
(3) Three-dimensional starch size distribution was measured for four cells near the central cheek region of a single caryopsis.
(4) The method of impulse gradient of NMR spin-echo was applied for studying limited water diffusion in yeast cells and embryons of wheat caryopsis.
