Other claims from this paper (14)
- Observation Type I foxtail millet strains from Europe and Afghanistan initiate floral buds without short-day stimulus.
- Intervention effect Panicle development of Type I strains is accelerated by short-day and high temperature conditions.
- Observation Strains from Okinawa, Batan Is. and Lan-Yu Is., sensitive to daylength, did not necessarily need short-day stimulus for panicle initiation.
- Intervention effect Panicle development of the Okinawa, Batan Is. and Lan-Yu Is. strains was accelerated by short day.
- Observation Type II strains from low latitudinal areas have a long basic vegetative growth period.
- Intervention effect The duration of the basic vegetative growth period of Type II strains is reduced by high temperature conditions.
- Observation Type II strains need many cycles of short-day to induce floral buds.
- Intervention effect The requirement of short-day cycles for floral initiation and morphological development is reduced by aging.
- Intervention effect Heading of the Halmahera Is. (2°N) strain, representative of Type II, is accelerated by 10 hrs. of light.
- Observation The strain from Thailand is sensitive to a wide range of daylength.
- Observation The Thailand strain should be identified as a fourth type, Type IV, characterized by a long basic vegetative growth period and high sensitivity to daylength.
- Observation Strains from the Temperate Zone are sensitive to changes of daylength.
- Observation Strain 403 from Kochi Prefecture, an obligate short-day plant and Type III representative, shows a striking response to daylength only one week after sowing.
- Observation Only a few cycles of short-day stimulus are enough for floral induction in strain 403.
