The yield of the oligogalacturonic acid was more than 54.3%, mainly with a degree of polymerization (DP) 2 and 3, the yields of which were 26.7% and 27.6% respectively.

由离子色谱法和薄层层析法检测得知在此条件下寡聚半乳糖醛酸的产率大于54.3％，其中以二糖和三糖为主，产率分别为26.7％和27.6％；

The double mutation also reduced short (degree of polymerization (DP) 5–6) and long (DP 12–23) amylopectin chain contents in the grain and increased the medium long types (DP 7–11).

双突变还降低了短（聚合度（DP）5-6）和长（DP 12-23）支链淀粉链的含量、增加了中长型（DP 7-11）支链淀粉的含量。
