Other claims from this paper (9)
- Intervention effect About 75% of seedlings at least four weeks old flowered after 12–15 weeks of cold treatment.
- Observation Cold treatment beginning at three weeks produced panicles in 22% of seedlings.
- Observation One- and two-week-old seedlings did not produce panicles after cold treatment.
- Observation Four-week-old seedlings needed at least nine cold weeks for some panicles.
- Association Thirteen-week-old seedlings produced more panicles than four-week-old seedlings after 12 cold weeks.
- Intervention effect Removing 60% of herbage reduced panicle incidence, emergence duration and number relative to uncut plants.
- Observation In Vantage, 88% of panicles came from tillers emerging during cold treatment.
- Intervention effect Twelve-week cold treatment caused panicle formation in 22 diverse clones.
- Method / resource The procedure can shorten breeding generations and permit crosses within five months.
