- 摘要:
- 以凤仙花的9种花色株系为试材，通过盆栽试验，测定花瓣、叶片和茎干的色素物质、非结构性碳水化合物及可滴定酸含量，并进行了相关性分析。结果表明：花瓣越红，花青苷含量越高，且差异显著；橙色、浅红和白色花瓣的类黄酮和总酚的含量显著低于深红色系花瓣；粉红、浅红和紫红色花瓣类胡萝卜素含量显著高于其它色系花瓣；但紫色花瓣中花青苷含量较低，说明其主要色素物质可能不是花青苷。此外，在叶片和茎干内也检测到了少量的花青苷，花色越红其含量越高。各试材间叶片叶绿素a含量差异不大，而红色花瓣的株系叶片叶绿素b和叶绿素a+b含量显著高于白色和浅红色株系。通过相关性分析发现，花瓣可溶性糖含量与花青苷含量呈显著正相关；类黄酮含量与叶片淀粉和可滴定酸含量呈显著正相关，而与叶片淀粉含量呈极显著负相关；花瓣总酚含量与可滴定酸含量呈显著正相关；类胡萝卜素含量与叶片可滴定酸呈极显著正相关，而与茎干淀粉含量呈极显著负相关。
- Abstract:
- Taking Impatiens L.nine strains with different flower’s colours as test materials,the contents of pigment,nonstructural carbohydrates and titratable acid of petal,leaf and stem by pot experiment were examined,and their relativity was analyzed.The results showed that petal anthocyanin content was the redder the higher and their difference were significant.The contents of flavonoid and total phenol in orange,light red and white petals were significantly lower than petals of cardinal colour system.The contents of carotenoid in pink,pale red and purplish red petals were significantly higher than petals of other colour system.But anthocyanin content was low in purple petal,means main pigment in purple petal might not be anthocyanin.Moreover,a small amount of anthocyanin was detected in leaf and stem,and its content was the redder the higher.Chlorophyll a content of leaf had no significant among test materials,whereas the contents of leaf’s chlorophyll b and chlorophyll a+b of red petal strains were significantly higher than white and pale red strains.By correlation analysis,it was found that soluble sugar content of petal had significant positive correlation with anthocyanin content；flavonoid content had significant positive correlation with the contents starch and titratable acid of leaf,whereas showed very significant negative correlation with soluble sugar content of leaf.Relativity between total phenol and titratable acid was significant positive correlation in petal,and relativity between carotenoid contents of petal and titratable acid content of leaf was very significant positive correlation,whereas showed very significant negative correlation with starch content of stem.
