(2) There are abundant and diverstile Malus Pumila polysaccharides in apple pomace, however, few systematic isolation and analysis have been done about them.

(3) The physio-biochemical changes in respiration rate, ethylene production, polyphenol oxidase(PPO) and enzymatic browning of fresh-cut apple(Malus pumila Mill) induced by wounding were investigated.

(4) Apple: a deciduous Eurasian tree (Malus pumila) having alternate simple leaves and white or pink flowers.

(5) Changes of endogenous abscisic acid (ABA) in the leaves of spur-type varieties (or bud variant types) of apple of Malus pumila were determined by GC.
