摘要
狗枣猕猴桃果实采后软化过程分两个阶段，第一阶段软化较快，起主要作用的阶段性专一酶是淀粉酶；第二阶段软化较慢，起主要作用的阶段性专一酶是多聚半乳糖醛酸酶。乙烯释放对果实软化有促进作用；保护性酶（过氧化物酶。过氧化氢酶）出现在果实软化后期，因而不是果实软化的阶段性专一酶。
The physiological and biochemical analysis indicated that A ctinidia kolomidta's fruit was respiratory climacteric. Its softening process after harvested included two phases; in the first phase fruit softened very quickly and during the period starch enzyme, a kind of stage specific enzyme played (SSE) amylasea main role in softening; in the second phase softening hecame low, and polygalacturonase (PG) was a kind of stage specific enzyme (SSE) which was important during softening. Ethylene (ETH) could accelerate softening; the maximum activities of protective enzymes peroxidase (POX) and catalase (CAT), were found in the second softening stage. They weren't SSE which caused fruit to soften.
