Growth Pattern and Copper Accumulation in Callus of Datura metel

Yulita Nurchayati, Santosa Santosa, Laurentius Hartanto Nugroho, Ari Indrianto


This experiment was aimed to evaluate the copper accumulation using callus culture of Datura metel L. The culture was established from leaves onto MS contained NAA 2.5 mg/L and Kinetin 0.5 mg/L as the control. The exposure of the culture was carried out by 2 copper compounds as treatment, i.e. CuCl2.2H2O and Na2CuEDTA at level concentration 0.; 0.1; 5; 10; 15; and 20 M. The growth pattern of callus in control showed increasing growth rate in 36 days, whereas exponential stage was reached at 12-20th doi*. Whilst, after 10 doi, the treatment showed constant growth pattern. The absorption rate of the culture was increased by the addition of the CuCl2.2H2O at 5 15 M of level concentration but declined at 20M. The maximum rate of accumulation of Cu (0,1519 mg g-1) was obtained at 15 M. Instead, the addition of Na2CuEDTA at 5 20M of level concentration showed the significant increment while the maximum accumulation was obtained at 20M (0,1420 mg g-1). The existence of chelator in copper compound reduced the rate of toxicity while all tolerance index values were between 66,24 and 97,28 %.The results suggested the role of callus of D. metel as that fairly absorbed and accumulated Cu2+. Exposure with CuCl2.2H2O indicated higher accumulation than Na2CuEDTA.
