不同倍性小型西瓜果实中番茄红素、瓜氨酸含量比较分析

Comparative Study on Lycopene and Citrulline Content in Different Ploidy Mini-watermelons Fruit

采用分光光度法测定比较分析9组纯合二倍体及其人工诱变的同源四倍体小型西瓜的番茄红素、瓜氨酸含量。结果表明:与对应的二倍体小型西瓜相比,同源四倍体小型西瓜番茄红素、瓜氨酸含量均随着倍性的增加而增加,其中番茄红素增幅最高的为PI4,增幅达28.27%;瓜氨酸含量增幅最高的为PI8,增幅达19.12%。番茄红素含量依次为大红瓤>红瓤>粉红瓤>黄瓤,与其瓤色有关。瓜氨酸含量依次为黄瓤>大红瓤=红瓤>粉红瓤,大红瓤与红瓤之间差异不显著,其它各个材料之间均达显著水平。

Lycopene and citrulline content of 9 materials of pure diploid mini-watermelons cultivars and homologous tetraploid mini-watermelons were determined by Spectrophotometry.The results showed that compared with the diploid,lycopene and citrulline content of homologous tetraploid mini-watermelons were increased along with the increase of ploidy.Among which,the highest lycopene content was PI4,increased 28.27%.And the highest citrulline content was PI8,increased by 19.12%.There was a correlation between lycopene content and flesh color,and bright red fleshred fleshpink fleshyellow flesh.Citrulline content of mini-watermelons yellow flesh〉bright red flesh and red flesh〉pink flesh,between bright red flesh and red flesh was no significant difference,and among other materials had reached significant levels.
