五种石蒜属植物不同部位淀粉粒度分布差异的研究
Study on Distribution Difference of Starch Particle Size of Different Parts in 5 Species of Lycoris (Amaryllidaceae
摘要
Abstract
[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 μ.m2,91.457-1 136.025 μm2,50.370-957.309 μm2 and 42.988-949.062 μm2.The percentages of small starch granules of Lycoris aurea,Lycoris chinensis and Lycoris sprengeri were higher than big starch granules,but Lycoris radiate was opposite.The starch granules of Lycoris longituba had no significant difference.In 5 species of Lycoris,the starch granules of bulbs were more than those in roots and leaves.The starch granules content of roots of Lycoris aurea,Lycoris longituba and Lycoris sprengeri was more than that in leaves.And Lycoris radiate was opposite.The starch granules of root and leave in Lycoris chinensis had no significant difference.[Conclusion] Five species of Lycoris plants had significant difference on the distribution of starch grains.关键词
