Khả năng phục hồi đất paddy bị ô nhiễm mangan bằng hai loài cây tích lũy mangan (Phytolacca americana và Polygonum hydropiper) có hỗ trợ của axit citric
Tóm tắt
Mục đích của nghiên cứu này là điều tra tiềm năng phục hồi sinh thái của hai loài cây tích lũy mangan, Phytolacca americana L. và Polygonum hydropiper L., trên đất paddy bị ô nhiễm mangan. Sự phát triển sinh khối, nồng độ Mn trong mô thực vật và hiệu quả tiềm năng loại bỏ Mn từ đất của hai loài cây này đã được nghiên cứu với axit citric, và cơ chế tác động của axit citric trên hai loài cây này đã được phân tích bằng cách kiểm tra hoạt động của rễ, hoạt động của enzyme superoxide dismutase (SOD), peroxidase (POD) và catalase (CAT) trong lá, cũng như nồng độ O2·− và H2O2 trong lá. Kết quả cho thấy rằng sinh khối của hai loài cây này được thúc đẩy ở mức axit citric thấp (3 mmol kg−1). Nồng độ Mn trong thực vật và lượng Mn được loại bỏ khỏi đất bởi thực vật thông qua việc thu hoạch được tăng cường khi áp dụng axit citric ở mức thấp và trung bình (10 mmol kg−1). Kết quả cũng cho thấy rằng hoạt động của rễ được tăng cường ở mức axit citric thấp và bị ức chế đáng kể dưới mức trung bình và cao (15 mmol kg−1), điều này cho thấy chức năng hỗ trợ của mức axit citric thấp và chức năng ức chế của mức cao trong việc phát triển sinh khối cây. Ở mức áp dụng axit citric thấp và trung bình, O2·− trong lá thực vật tăng mạnh, và hoạt động của SOD, POD và CAT cũng tăng mạnh, khiến nồng độ H2O2 rất giống với mẫu đối chứng, bảo đảm sức khỏe cho thực vật. Tuy nhiên, ở mức áp dụng axit citric cao, O2·− tiếp tục tăng mạnh, trong khi hoạt động của ba enzyme chống oxy hóa giảm mạnh, gây ra nồng độ hydrogen peroxide cao hơn nhiều so với mẫu đối chứng, do đó đe dọa sự sống còn của cây. Nghiên cứu hiện tại cho thấy tiềm năng của P. hydropiper trong việc phục hồi đất bị ô nhiễm với mức mangan tương đối thấp.
