Abstract:
Taking ‘Liaoning No.1’ and ‘Lipin No.1’ walnut varieties as materials，the main meteorological factors，the critical frost damage occurred period of flower buds and different cold hardiness on male and female flower buds between precocious cultivar ‘Liaoning No.1’ and late maturing ‘Lipin No.1’ (Juglans regia L.) were studied by observation of natural environment and artificial freezing test.The results showed that，cold hardiness of flower buds would be weakened by extreme cold winter，spring sudden cooling and continuous haze.The majority of injuries in flower buds occurred both December and March.Female flower buds resistant cold was more than males and ‘Lipin No.1’ was better than ‘Liaoning No.1’.Therefore，male flower buds of walnut and late maturing cultivar in a cold winter with unusual low temperature should be pay more attention.
