| 释义 | caryopsis noun[ C ] botany specializeduk /ˌkær.iˈɒp.sɪs/ us /ˌker.iˈɑːp.sɪs/pluralcaryopsesuk /ˌkær.iˈɒp.siz/ us /ˌker.iˈɑːp.siz/ a small fruit that contains a single seed that is joined as one with the fruit, for example the grains found in rice, corn, and wheat: 颖果 Each kernel on an ear of corn is a caryopsis, where the seed is fused to the wall of the ovary that contains it.玉米穗上的每个颗粒都是颖果，其中种子与包含它的子房壁融合在一起。 The agriculture students learned about the cultivation of feed plants by studying the caryopses of barley and wheat. In grains that contain caryopses, the fruit and the seed are essentially the same.

In any event, the use of caryopses would be inappropriate because spikelets would be used for reseeding. Our objective was to assess the extent to which mechanical and enzymatic separation of caryopsis tissues is possible. Any dead caryopses or seeds were also removed at the same time. However, no significant difference was observed between control caryopses and ethanol-treated ones, as long as the latter had not yet germinated. Germination tests were carried out on spikelets and extracted caryopses. The caryopsis coat was isolated during mid-ripening, dissected and microscopically characterized. Approximately 56,000 cells were isolated per caryopsis coat. None of the caryopses matured in this regime germinated at zero time compared with an initial germination of 42% for the well-watered control. Four x 10 intact dry caryopses or dry seedlings at different developmental stages were used in this experiment. One of these strategies is the phenotypic germination plasticity due to distinct caryopsis size groups. When the husk was retained, the effect of smoke water was less than when applied to the caryopses alone. Seedlings were established by sowing at least four caryopses on the surface of 15-cm-diameter plastic pots. These problems do not apply to the same extent for caryopses. Results are means of four replications of 50 caryopses each. These examples are from corpora and from sources on the web.
