Change in the Flower Type of White Lotus (Nelumbo nucifera) during Flowering Period in Muan Hoesan-Lake

This study was conducted to investigate flowering type and method of white lotus (Nelumbo nucifera) in Muan Hoesan-lake, and to enhance the utilization of lotus flowering. Blooming time of white lotus was 6:00 a.m. at 1 day after flowering (DAF), 5:40 a.m. at 2 DAF, 6:10 a.m. at 3 DAF, and 5:10 a.m. at 4 DAF, and all the lotus flowers bloomed were closed until 12:00 a.m. Maximum flower diameter at 10:00 a.m. at 1 DAF was 7.6 cm, at 7 a.m. at 2 DAF 25.2 cm, 8 a.m. at 3 DAF 23.7cm, and 10 a.m. at 4 DAF 22.2 cm. Number of petals bloomed was 14. Two petals were fallen at 3 DAF and all the petals were withered until 12 a.m. at 4 DAF. All the petals bloomed upright at 1 DAF, horizontal at 2 DAF and upright and oblique at 3 DAF. No petals bloomed downward at 1 and 4 DAF were observed. Overall results indicate that the flowering type and method including blooming time, size, and direction during flowering stage would be significant parameters for optimum production of white lotus flowers.
