探讨了3种棕榈植物的总酚、可溶性单宁、结合态单宁和总缩合单宁含量的季节性变化规律.研究结果表明:布迪椰子的总酚、可溶性单宁和总缩合单宁含量在4个季节中几乎没有变化；沼地棕和油棕的总酚含量在冬季显著提高；布迪椰子和沼地棕的结合态单宁在冬季明显下降,而油棕不然；布迪椰子总缩合单宁含量与总酚含量的变化趋势相似,沼地棕和油棕的总缩合单宁含量与总酚含量的变化趋势不同.

The studies on the seasonal changes of total phenolics (TP),soluble condensed tannin (SCT),bound condensed tannin (BCT) and total condensed tannin (TCT) content in the leaves of high cold resistant Butia capitata,the medium cold resistant Acoelorrhaphe wrightii and cold sensitive Elaeis guineensis were conducted in the four seasons.Differences in the accumulation of tannins associated with different cold resistant palm species occurred in response to seasons.The content of BCT in B.capitata and A.wrightii markedly decreased from autumn to winter,but not for E.guineensis.The change trend of B.capitata TCT was the same as that of TP,but not the same for that of A.wrightii and E.guineensis.The results showed that the high cold resistant B.capitata,the medium cold resistant A.wrightii and cold sensitive E.guineensis had different tannin seasonal change patterns.This character may help the further investigations into the plant cold resistant mechanism.
