摘　　要：为探明储藏年限对辣木种子萌发、生理指标及净水效果的影响,以自然储藏1年、2年、3年和4年的辣木种子为试验材料,测定种子发芽率,观察种子萌发情况,研究生理特征及净水效果的变化情况。结果表明,辣木种子发芽率随储藏年限的增加逐渐降低,MDA和可溶性蛋白含量随储藏年限的增加呈先升后降趋势,但储藏4年的种子MDA和可溶性蛋白含量下降幅度较大,POD活性和CAT活性均随着储藏年限的增加显著下降。相关性分析发现,发芽率与可溶性蛋白含量呈显著正相关,电导率与POD活性、CAT活性分别呈显著和极显著正相关,POD与CAT间显著正相关。研究发现,储藏年限对种子净水效果影响不大,建议在辣木栽培生产上,选择储藏1~2年的种子,保存时间长的种子可作为天然净水剂等被开发利用。In order to study the influence of storage years on germination,physiological characteristics and water purification effect of Moringa oleifera seeds.Moringa oleifera seeds that were stored for 1 year,2 years,3 years and 4 years were used as experimental materials.The germination rate of seeds was measured,the germination situation was observed,and the changes of physiological characteristics and water purification effect were studied.The results showed that the germination rate of Moringa oleifera seeds decreased gradually with the increase of storage years,and the contents of malondialdehyde(MDA)and soluble protein increased at first and then decreased.The contents of MDA and soluble protein of Moringa oleifera seeds stored for 4 years decreased significantly.The activities of POD and CAT reduced significantly with the increase of storge years.Correlation analysis indicated that germination percentage had a significant positive correlation with soluble protein content.There were significant and extremely significant positive correlations between electrical conductivity and POD and CAT,respectively.There was a significant positive correlation between POD and CAT.The study found that the storage period had little effect on the water purification effect of seeds.It was suggested that stored seeds for 1 and 2 years could be used about the cultivation and production of Moringa oleifera,and the seeds with a long storage time could be developed and utilized as natural water purifiers.
