摘要
甘蔗幼苗的苹果酸酶活性主要分布在叶片中,在叶鞘、幼茎和苗根中很少。甘蔗+1叶的苹果酸酶活性在分蘖末期出现高峰,以后一般随生长进程而呈下降趋势。在工艺成熟期甘蔗受到重霜危害时,+1叶中的苹果酸酶活性几乎消失。不同基因型之间的苹果酸酶活性也表现出明显的差异,但在不同的生长期表现不同,与当时所处的生长状况有关,生势较旺盛的一般活性较高。
Malic enzyme was highly active in leaf blade,but insignificant in leaf sheath,young stalk and root of young plant of sugarcane(Saccharum spp.). Malic enzyme activity in +1 leaf showed a high peak at late tillering stage, and then declined gradually with growth.And the activity almost disappeared after subjected to the severe frost at maturing stage.The activity in +1 leaf was significantly different among nine sugarcane genotypes at different growth stages,and the genotypes grown more prolifically generally possessed higher malic enzyme activity at a certain stage.
