Cucumis (Cucurbitaceae). C. melo (Casaba, honeydew form) has lack of access to oxygen (in the fruit) as the mechanism blocking germination, see Section II (a). The seeds still germ 100% in 4-6 d in 70D after 3 y of DS. C. melo (netted form) showed remarkable effects of DS. The DS increased the percent germination, the rate of germination, and eliminated the promoting effect of light. Fresh seeds germ. 70L(61% in 1-4 w) and 70D(8%). After 2 m DS at 70 the seeds germ. 70L(87%) and 70D(35%), both in 2-6 d. After 12 or 18 m of DS the seeds germ. 70D(100% on the 3rd d). These results are all on the same sampie of seeds

Cucumis (Cucurbltaceae). C. melo is the common melon. Both the cassaba or honeydew and the netted or canteloupe types were studied. C. melo (cassaba) germ. 100% in 4-6 dafter washing the seeds for only 10 minutes. When the WC was continued for 7 d, the seeds also germ. 100%, but not until 4-6 d after removal from the washing water. This shows that immersion in water inhibits germination, possibly because the germinating seeds require abundant oxygen. The seeds are connected to the interior of the fruit by a thin filament. It is suspected that inhibitors are transmitted through this filament as in Capsicum. When the filament is broken, germination begins. Light, GA-3, or DS at 70 for 2 m had no effect. C. melo (netted) seeds were WC for 10 minutes. These fresh seeds had germination stimulated by light and GA-3. They germ. 70L(61% in 1-3 w), 7013 GA- 3(48% in 1-3 w), and 7013(8%). Germination was much lower in seeds WC for 7 d. The light requirement diminshes on 133. Seeds DS for 2 m at 70 germ. 70L(87%) and 70D(35%). Two commercial strains were received after months of DS and germ. 90% in 2-5 d in either 70D or 70L showing the elimination of the light requirement on DS.
