UJI KETAHANAN TERHADAP ALUMINIUM DAN pH RENDAH PADA JAGUNG (Zea mays L) VARIETAS PIONEER DAN SRIKANDI SECARA IN VITRO

Abstract: One effort to increase maize productivity is by using marginal land for maize plantation. The marginal land that can be used is acid soil, but the problem are Al toxicity and low pH. To cope with these problems, cultivars having tolerance to Al toxicity and low pH are needed. Plant material used in this research were two maize varieties (Pioneer and Srikandi). Media selection is used there are 4 doses treatment aluminium (0, 250, 500 and 750 ppm AlCl3). All variables were observed except at the variable width … Show more

“…[17] explained that soil pH affects nutrient availability either directly by increasing the availability of Mn, Zn, Zu, and Fe and decreasing N, K, Ca, Mg, and S at low pH or indirectly increasing the availability of P and B at low and high pH. In addition, high concentrations of toxic elements such as Al in acid soils can affect the performance of plant roots to absorb nutrients thereby limiting plant growth and production [18].…”

“…Kondisi pertanaman (kiri) pada hasil (kanan) pada panen kelima Kelarutan aluminium yang tinggi pada tanah kering masam membatasi ketersediaan unsur hara lain dan dapat menimbulkan keracunan bagi tanaman. Kondisi tersebut menyebabkan pertumbuhan dan hasil tanaman yang diusahakan umumnya rendah (Dalimunthe et al, 2015).…”

“…Sebagai kontrol adalah perlakuan tanpa penambahan aluminium ke dalam media dan pH dipertahankan pada 6.0-6.5. Perlakuan cekaman dilakukan dengan menambahkan 500 ppm AlCl3.6H2O ke dalam larutan hara, mengikuti metode Dalimunthe et al (2015), dan pH larutan dipertahankan pada 4.0-4.5. Media tanaman yang digunakan berupa pasir kali yang telah dicuci bersih.…”
