[Objective]The research aimed to study the characteristics of Lycoris starch granule. [Method] We measured the surface area of starch granule of Lycoris aurea,Lycoris radiate,Lycoris longituba,Lycoris chinensis and Lycoris sprengeri,and calculated the number of starch granules in the micrograph by software scophoto. [Result] The surface area range of starch granules in Lycoris aurea,Lycoris radiate,Lycoris longituba,Lycoris chinensis and Lycoris sprengeri was 84. 864- 883. 926 μm2,12. 716- 986. 444 μm2,91. ...
