绪言凝胶电泳技术已被用来了解各种作物植株发育过程和种系发育的途径。已发现不同基因型中过氧化酶活性水平不一样。据报导,在豌豆(Muller 1969)、蕃茄(Evans andAlldri dge 1965)和普通小麦(Liang1974)中,过氧化酶活性与植株高度的下降成正相关。在经济作物中有关同功酶作用的另外试验证明可能用作制订作物改良生化育种计划的基础。从这个角度出发,本文着手研究:找出过氧化酶活性与植株高度的关系及其与基因型完全不同的普通小麦品种的籽粒重量的相 Introduction Gel electrophoresis has been used to understand the developmental processes and developmental pathways of various crops. Different genotypes have been found to have different levels of peroxidase activity. It has been reported that peroxidase activity is positively correlated with the decline of plant height in peas (Muller 1969), tomato (Evans and Allied dge 1965) and common wheat (Liang1974). Additional tests on the role of isoenzymes in cash crops have proven to be likely to be used as a basis for developing biochemical breeding programs for crop improvement. From this perspective, this paper proceeds to study: to find out the relationship between peroxidase activity and plant height and the grain weight of common wheat cultivars with completely different genotypes
