几种红树植物叶片多酚氧化酶、过氧化物酶活性初报

研究了生长于广东沿海地区，即香港米埔、湛江高桥、大亚湾澳头、稔山、三门岛和恩平洪窑等地的白骨壤（Avicennia marina)、秋茄（Kandelia candel)、木榄（Bruguiera conjugata)、红海榄（Rhizophor stylosa)及苦槛蓝（Hyoporum bontioides)等5种红树植物叶片多酚氧化物酶（Polyphenol oxidase,PPO)、过氧化物酶（Peroxidase,POD)活性，除发现同一地区不同种的红树植物叶片酶活性存在种间差异外，生长于不同地区的同一种红树植物其叶片酶活性亦存在较大的差异。本文对其可能原因进行了探讨。

A preliminary report on the activities of polyphenol oxidase and peroxidase in the leaves of some mangrove plants

This paper reports the activities of polyphenol oxidase (PPO) and peroxidase (POD) in the leaves of Avicennia marina, Kandelia candel, Bruguiera conjugata, Rhizophora stylosa, Hyoporum bontioides, etc. , growing in some coastal areas in Guangdong province, China. It is found that, in addition to the differences in the activities of PPO and POD in the leaves of mangrove plants of different kinds, mangrove plants of the same kind but growing in different areas also differs from each other. Possible reasons are discussed in the paper.
