     Abstract: Bougainvillea spectabilis Willd was introduced from South America. The factors of flower falling were studied in Xianning area under the conditions of different light temperature and moisture. The results showed that the plant was forced to be dormant by low temperature. The flowers fell off abnormally for inadequate sunshine and withered early for too much soil moisturein non-dormant period. The flowers were not sensitive to sunshine and withered later under the condition of low temperature or low soil moisture in dormant period.
