摘要：

Enzyme preparations from bulbing onion plants contained sucrose: sucrose fructosyltransferase and fructan hydrolase activities. Enzyme activities were highest in the leaf bases. Fructosyltransferase activity increased from the outer to the inner leaf base while hydrolase activity decreased. The enzyme distribution suggests that most fructan synthesis occurs in the inner leaf bases and most fructan hydrolysis occurs in the outer leaf bases of the onion bulb. © 1979.
