the average amylose starch content of jimai 22 lowered after treatment with ems, while it did not changed significantly in mutagenized jimai 20.
济麦22诱变材料直链淀粉均匀含量低于未诱变材料,而济麦20白勺相差不大;
the results of x-ray diffraction show that the crystal structure of high amylose starch and the starch acetate differs greatly, which implies that the crystal structure is damaged during substitution.
