摘要：

为了明确黑果枸杞不同组织器官内酚类物质以及钙对土壤盐渍化响应。以一年生(F₁)、二年生(F₂)、三年生(F₃)的黑果枸杞分枝及野生(Q₁)、轻度(Q₂)、中度(Q₃)、重度(Q₄)盐渍化土壤的黑果枸杞三类器官为材料,采用比较及主成分分析评价黑果枸杞的品质。结果表明,不同处理下黑果枸杞各指标存在显著差异,果实中 Q₁钙与黄酮含量(1.623 g/L,73.963 mg/g)最高,Q₄总酚、花青素及原花青素含量(2.049 mg/g,151.836 mg/L,286.167 mg/g)最高;分枝中 Q₂钙含量(4.167 g/L)最高, Q₃总酚含量(0.491 mg/g)最高,Q₄黄酮、花青素和原花青素含量(25.704 mg/g,2.463 mg/L,10.208 mg/g)最高;叶:Q₁钙与黄酮含量(5.469 g/L,34.593 mg/g)最高,Q₄总酚及原花青素含量(0.943 mg/g,21.000 mg/g)最高,Q₂花青素含量(2.880 mg/L)最高;一~三年生分枝:F₁钙含量(2.561 g/L)最高,F₂总酚、花青素及原花青素含量(0.409 mg/g,0.163 mg/L,8.858 mg/g)最高,F₃黄酮含量(34.593 mg/g)最高。土壤盐分与各指标之间存在相关性,与果实钙含量显著正相关,与果实黄酮含量及叶钙含量呈极显著正相关。果实钙含量与叶钙含量显著正相关,与果实黄酮含量呈极显著正相关,与果花青素含量、分枝黄酮含量呈显著负相关,同时,其与果实原花青素含量呈极显著负相关。

Abstract:

To clarity the response of phenols in different organs of L.ruthenicum Murr.to soil salinization.The stems of annual(F₁),biennial(F₂),triennial(F₃)and wild(Q₁),mild(Q₂),moderate(Q₃),and severe(Q₄)salinized soil were used as experimental materials.The quality of L.ruthenicum was evaluated by principal component analysis.It showed that there were significant differences in each index of L.ruthenicum under different treatments.Among the fruits,the content of wild Q₁ calcium and flavonoids(1.623 g/L,73.963 mg/g)was the highest,the content of total phenol,anthocyanin and procyanidins in Q₄ was the highest(2.049 mg/g,151.836 mg/L,286.167 mg/g),in the shoot,calcium content(4.167 g/L)in Q₂ was the highest,the total phenol content of Q₃(0.491 mg/g)was the highest,the content of flavonoids,anthocyanins and procyanidins in Q₄ was the highest(25.704 mg/g,2.463 mg/L,10.208 mg/g),in leaves,the content of calcium and flavonoids(5.469 g/L,34.593 mg/g)was the highest in Q₁,the content of total phenols and procyanidins(0.943 mg/g,21.00 mg/g)was the highest in Q₄,the content of anthocyanin in Q₂ was the highest(2.880 mg/L);among the annual branchs,the calcium content(2.561 g/L)was the highest in F₁,the contents of total phenols,anthocyanins and procyanidins(0.409 mg/g,0.163 mg/L,8.858 mg/g)in F₂ were the highest,the content of flavonoids(34.593 mg/g)in F₃ was the highest.There was a correlation between soil salinity and various indicators. It is significantly positively correlated with the fruit calcium, and extremely significantly positively correlated with the frui flavone and the leaf calcium. The fruit calcium was significantly positively correlated with the leaf calcium, extremely significantly positively correlated with the fruit flavone, significantly negatively correlated with the fruit anthocyanin and the branch flavone, extremely significantly negatively correlated with the fruit proanthocyanidin.
