几个甘蔗品种的过氧化物酶活性及其同工酶多样性的比较研究

COMPARATIVE STUDIES OF PEROXIDASE ACTIVITIES AND ISOENZYMES IN SIX VARIETIES OF SUGARCANE

摘要: 在粤农７６／１６９，Ｑ７５，桂糖１号，福蔗７７／３００３，印度ＣＯ３３１和ＰＯＪ２８７８等６个品种甘蔗中，同一品种不同器官的过氧化物酶活性有较大的差别；不同品种同一器官过氧化物酶活性也不同，各品种的叶片，叶鞘，茎尖，成熟茎和根的过氧化物酶同工酶数量差异较大，同一品种各器官中以代谢旺盛的叶片和叶鞘的同工酶数较多，不同品种的同一器官中同工酶数也有较大的变化。

Abstract: The results of this investigation indicated that peroxidase activities were very different both among the different organs in the same variety and among the same organs of different varieties in 6 sugarcane cultivars,i.e. Yuenong 76/169,Q75,Guitang NO.1,Fuzhe 77/3003,India CO 331,and POJ 2878.In the blades, petioles, stem tips, mature stems, and roots, the numbers of isoperoxidases were significantly different both among the organs of the same variety and among the same organs of different varieties.
