摘要
由同一基因型产生的单倍体、二倍体和四倍体黄瓜的叶面积和花大小等形态性状、单位面积叶绿素含量和苹果酸脱氢酶(MDH)表达量等生理生化指标随染色体倍性的增加而增加,过氧化物酶(POD)活性则随倍性的增加而降低,剂量效应明显;其他形态指标和可溶性蛋白含量等与染色体倍性无明显相关性。
Haploid, diploid and tetraploid cucumbers (Cucumis sativus L.) developed from the genotype ‘Jinlvsihao’ were used as experimental materials. The results showed that leaf and flower size, chlorophyll content and malate dehydrogenase (MDH) electrophoretogram intensity increased and peroxidase (POD) activity decreased as the genome doubled, indicating significant gene dosage effect. The other morphological traits and soluble protein content showed no significant relation to ploidy levels.
