The results showed that ethylene could accelerate the abscission during incubation,Ca2+-ATPase activity first rose sharply and then declined quickly. Subsequently,there was a increase in the activity of Endo-PG,PE,CMC-Na enzyme in abscission zone.

• 结果表明:外源乙烯加速了花柄的脱落,刺激了其离区的Ca2+-ATPase活性先升高后下降,随后离区CMC-Na、Endo-PG、PE活性升高;
