摘要
With long-term natural selection, the fruit and seed of plants formed various morphological and physiological properties adapting to various mediums of dispersal which are benefits to disperse extend the space of individuals and to enhance the population booming. Cellulose is the main chemical component of plant cell walls and has an important physiological function in plants. However, most research mainly focused on use of cellulose, synthesis, modification etc. @@@ In this study we analyzed the cellulose crystallinity of different parts of Fructus Schisandrae [the fruits of Schisandra chinensis (Turcz.) Baill.] by means of the infrared spectroscopy and X-ray diffraction through the study of crystallinities of cellulose in different parts of Fructus Schisandrae, so as to explain the relationship between chemical structure of cellulose and seed dispersal pattern. The results showed that the crystallinities of cellulose in different parts of Fructus Schisandrae are different, seed coat cellulose 85.35%, pericarp cellulose 62.54% and embryo cellulose 51.59%. These data highlight that the differences of crstallinity of cellulose are adaption to seed dispersal way.
