摘要:
采用盆栽试验，将葡萄和镉超富集植物龙葵混种于镉污染土壤，研究了葡萄混种不同密度龙葵(株行距分别为40 cm×80 cm、40 cm×40 cm、20 cm×40 cm和20 cm×20 cm)对两者镉形态及分布的影响。结果表明，镉在葡萄根系及地上部分主要储存在可溶性组分，占41.96%~63.40%，其次为细胞壁组分，占24.38%~47.45%。混种在一定程度上降低了葡萄根系及地上部分亚细胞组分镉含量。随着混种密度的增加，葡萄根系及地上部分可溶性组分镉含量所占比例呈增加的趋势，而细胞壁组分镉含量所占比例呈降低的趋势。龙葵根系及地上部分镉主要分布在细胞壁及可溶性组分中，其中根系分别占32.56%~46.00%和38.83%~41.27%，地上部分分别占46.88%~63.40%和22.99%~47.45%。龙葵根系及地上部分亚细胞组分镉含量大小顺序为可溶性组分>细胞壁组分>细胞器组分。随着混种密度的增加，龙葵根系及地上部分亚细胞组分镉含量呈增加的趋势。就化学形态分布而言，混种降低了葡萄植株化学形态镉含量，且随混种密度的增加呈降低的趋势。混种还提高了葡萄植株乙醇和去离子水提取态镉含量所占比例，降低了氯化钠和醋酸提取态镉含量所占比例。随着混种密度的增加，龙葵植株乙醇和去离子水提取态镉含量所占比例增加，而氯化钠、醋酸和盐酸提取态镉含量所占比例降低。因此，这种亚细胞分布和化学形态镉变化是混种降低葡萄和龙葵镉毒害的重要解毒机制。
