APAKAH MAKSUD HYPERACCUMULATOR dalam CORSICA?
Hyperaccumulator
Hyperaccumulator adalah tumbuhan yang mampu tumbuh di dalam tanah dengan kepekatan logam yang sangat tinggi, menyerap logam-logam ini melalui akarnya, dan menumpukan tahap logam yang sangat tinggi dalam tisu mereka. Logam tertumpu pada paras yang beracun kepada spesies yang berkait rapat yang tidak disesuaikan dengan pertumbuhan di tanah metalik. Berbanding dengan spesies yang tidak menyerap akustik, akar hyperaccumulator mengekstrak logam dari tanah pada kadar yang lebih tinggi, memindahkannya lebih cepat ke pucuk mereka, dan menyimpan jumlah yang besar dalam daun dan akar. Keupayaan untuk menyerap logam toksik berbanding dengan spesies yang berkaitan telah terbukti disebabkan oleh ekspresi gen perbezaan dan pengawalan gen yang sama di kedua-dua tumbuhan. Lebih 500 spesies tumbuhan berbunga telah dikenal pasti sebagai mempunyai keupayaan untuk menyerap logam dalam tisu mereka. Tumbuhan hyperaccumulating memegang minat untuk keupayaannya untuk mengekstrak logam dari tanah tapak yang tercemar untuk mengembalikan ekosistem kepada keadaan yang kurang toksik. Tumbuhan ini juga berpotensi untuk digunakan untuk melombong logam dari tanah dengan kepekatan yang sangat tinggi dengan menanam tumbuhan kemudian menuai mereka untuk logam dalam tisu mereka.
Definisi hyperaccumulator dalam kamus Corsica
Takrif hiperakumulator dalam kamus adalah tumbuhan yang menyerap toksin, seperti logam berat, kepada kepekatan yang lebih besar daripada itu di dalam tanah di mana ia tumbuh.
