摘　　要：本研究对18份西藏通麦野梅资源进行花期性状分析,结果显示:通麦野梅的花期多在1月中旬,花态多为碟型,花枝为中花枝的最多,刺花枝和束花枝最少,花色全部呈白色,花香多为淡香,大多数通麦野生梅着花繁密,花瓣均为单瓣,花蕾以球形居多,花萼数量多为5片,多数呈绛紫色,雌蕊1枚,多数短于雄蕊,雄蕊全部长于花瓣,花萼的遗传多样性最丰富,花径在17.84~22.88 mm,平均花径为20.05 mm,不同野梅花径差异显著。The present study analyzed the flowering characteristics of 18 wild Prunus mume resources in Tongmai,Tibet.The results showed that the flowering period of Tongmai wild Prunus mume is mostly in mid-January,and the flowers are mostly dish-shaped.The flowering branches are the most medium flowering branches,and the thorny flowering branches and bunch flowering branches.At least,the flowers are all white,and the floral scent is mostly light.Most of the wild Prunus mume have dense flowers,single petals,most of the flower buds are spherical,and the number of calyxes is mostly 5,most of which are purple,and 1 pistil.Most of them are shorter than stamens,and all stamens are longer than petals.The calyx has the most genetic diversity.The flower diameter is 17.84-22.88 mm,and the average flower diameter is 20.05 mm.There are significant differences in the diameter of different wild Prunus mume.
