To generalize elite germplasm and provide theoretical basis for Apricot Frost Protection measures, choose 'Weixuan 1', 'Youyi' and 'Longwangmao' as material, the experiment studied biological characteristic of the three species, including budding, flowering, floral organs cold hardiness of young fruit and fruit quality,the main results are as follows:
1. The field survey results of cold resistance show that elite germplasm 'Weixuan 1'has strong ability of anti-frost. The freezing rate of 'Weix...
