摘　　要：滇刺枣五个地理种源的同工酶分析＊汪云马显达关键词滇刺枣地理种源同工酶滇刺枣（ＺｉｚｉｐｈｕｓｍａｕｒｉｔｉａｎａＬａｍｋ．）是鼠李科（Ｒｈａｍｎａｃｅａｅ）枣属（Ｚｉｚｉｐｈｕｓ）落叶乔木，为一种新兴的多用途经济树木。在长期的天然杂交和地域隔绝下，形...A study has been made of isolating isoenzymes of POD and EST of Zizyphus mauritiana from 5 provenances with discontinuous polycrylamide gel system (Disc PAGE).The results have shown that there are differences present on the spectrum of the two isoenzymes in the tested plants.EST is more sensible to tell their relationships close or distant,and the differences in the Burma and Yunnan Provenances appear more obvious,while the Shuangbei and Yuanmao ones show no significant differences.And it needs further study if the latter two come from the same provenance.
