From July 3 to August 15, 1985, 168 groups of lotus, about one thousand seeds were sowed in the lotus garden in Modesto, California, United States. A total of 580 plants survived. 56 plants included 35 groups had bloomed in the same year and some of them came into squaring period only 30 to 35 days after sowing. Most plants end their growth period naturally before forsty season but some can't, the latter grow vigorously and their leaves are frozen when the forsty season come. These phenomena show that there are different responses to the sunlight and the temperature among genotypes of lotus.
