Abstract: The accumulation of nutrition characteristics and the change of popping characteristics were analyzed.Theshape of starch granule was observed.Kernel weight increased rapidly at 10 -35 d after pollination and then increasedslowly.Both starch content and fat content showed a single peak curve and peaked at 30 days,20 days after pollination ,respectively.Protein content decreased gradually.Both popping percentage and expansion multiple showed a slow -rapid-slow change.Cutin endosperm cell arranged orderly and closely.Starch granule presented polyhedron shape and arrangedtightly.The face of starch granule was attached with matrix protein.

Key words: Popcorn(ZeamaysL.var.evertaSturt), Nutritioncharacteristic, Poppingcharacteristic, Starchgranule
