Abstract:
Taking Impatiens L.nine strains with different flower’s colours as test materials,the contents of pigment,nonstructural 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.
