Pollen viability is to assess the activity of one of the basis of pollen cells,The activity assay results of cytological experiments and determine the accuracy of breeding success or failure. In this study,32 lily cultivars as experimental materials,comparison of different varieties of fresh lily pollen viability,germination rate differences, and different storage conditions hereinafter pollen viability differences by staining method and in vitro pollen germination method. The results showed that: It is more accurate to pollen viability of in vitro pollen germination method. Germination rate of Casa Blanca is highest namely 87. 33%,Yelloween is lowest namely 1. 33%. To uniform storage dry condition in room,pollen viability of different lily cultivars is obvious different by different storage time. Germination rate decrease as extension as storage times,but rate of descend is different by different cultivars. Pollen germination rate decrease as extension as storage times in cold storage,but rate of descend is slower than in room storage.
