DAYS TO FLOWERING AND FLOWERING PERIOD
The mean days to flowering was 168.62 ± 0.50 days for all individuals of the 57 western Kyushu populations.
The mean days to flowering in each region were 165.12 ± 0.87 days in the Tsushima populations, 166.78 ± 0.76 days in the Nagasaki mainland populations, 171.73 ± 0.87 days in the Goto Islands populations, and 180.28 ± 1.75 days in the Koshikijima Islands populations.
The shortest population (C 36: population number [8,9]) of days to flowering indicated 152.00 ± 4.00 days and the longest population (C 7) indicated 193.83 ± 6.70 days.
Both of these populations were the Tsushima populations, but the mean value in all Tsushima populations was 165.12 days, suggesting that the C7 population represents an outlier among the Tsushima populations studied.
The mean flowering period of all individuals of 57 populations in western Kyushu indicated 82.5 ± 2.7 days.
The mean flowering period in each region were 77.19 ± 2.32 days in the Tsushima populations, 88.87 ± 2.65 days in the Nagasaki mainland populations, 83.50 ± 3.48 days in the Goto Islands populations, and 76.23 ± 4.67 days in the Koshikijima Islands populations.
