| Abstract: | The temperature changes and drought influence on the flower bud differentiation of Litchi (Litch chinensis Sonn.) in Hainan Province. A discriminatory function formula mainly based on low temperature condition and arid index for Litchi variety Feizixiao was established to make judgement of the period of flower bud differentiation. The model passed F-test. The validation showed an accuracy ratio with 100%. |
