Abstract


Penelitian ini bertujuan untuk mengetahui pengaruh pemberian dosis Glomus fasciculatum terhadap tanaman Dahlia pinnata dalam mengakumulasi logam Pb dan efisiensi serapannya. Penelitian ini menggunakan variasi dosis mikoriza yaitu 0 gram mikoriza dan tanpa Pb (kontrol negatif), 0 gram mikoriza dengan Pb (kontrol positif), 5 gram mikoriza, 10 gram mikoriza, 15 gram mikoriza, 20 gram mikoriza, dan 25 gram mikoriza. Masing-masing tanaman yang diberi penambahan dosis mikoriza juga di beri penambahan Pb(NO3)2 dalam media sebanyak 200 mg/mg. Jumlah perlakuan dalam penelitian ini adalah 7 perlakuan dengan 4 ulangan. Hasil penelitian menunjukkan dosis 25 gram mikoriza Glomus fasciculatum berpengaruh nyata dalam meningkatkan efisiensi serapan Pb pada tanaman dahlia serta meningkatkan akumulasi logam Pb pada akar tanaman dahlia dan menghambat akumulasi Pb pada batang dan daun
