Abstract:: Taking superior individual plant of Xanthoceras sorbifoliaBunge in Yangling，Shaanxi Province as the research object，through field investigation and observation，the flowering phenology，morphological characteristics of flowers，floral dynamicthe space distribution pattern of the fertile flowers，pollen viability and stigma receptivity were studied and analyzed.The results showed that the flowering phase of superior individual plant lasts for 15 days，from the early April to the mid-to-late of April.Flowers on the middle and top of crown came into blossom before the lower，outer before the center.Flowers at the bottom of terminal inflorescence bloom firstly，lateral inflorescence almost open at the same time.Pollen vitality in the initial stage of the blossom was lower than fullbloom stage，and it reached the max value at around 5 days after flower，then decreased slowly.When the base of petals turned from bright orange to salmon pink，stigma receptivity achieved the highest level.
