RESPON PERKECAMBAHAN BENIH DAN PERTUMBUHAN SEMAI PINUS (PINUS MERKUSII JUNG ET DE VRIESE) DENGAN APLIKASI KONSENTRASI DAN LAMA PERENDAMAN LARUTAN ABITONIK

The research aims to study the response of seed germination and seedling growth of pine (Pinus merkusii jung et de vriese) with the application of solution concentration and dipping time abitonik conducted in South Pujon seedbed RPH, BPKH Pujon, KPH Malang. The experiment began in September 2008 until May 2009. The research method used was a factorial experiment with Randomized Block Design (RBD), consisting of two factors, namely the first factor and second factor soaking Abitonik growth regulator concentration. Factor I: Long soaking, consists of three levels: P1 = Old soaking 20 minutes, P2 = Length of 40 minutes of immersion, submersion Old P3 = 60 minutes or 1 hour, Factor II: Concentration of growth regulators Abitonik, K1 = Concentration of solution 0, 04 cc / liter of water., K2 = concentration of solution 0.06 cc / liter of water., K3 = concentration of solution 0.08 cc / liter of water, K4 = Concentration of solution 0.1 cc / liter of water. The research data from each observation parameters were analyzed by variance in accordance with the randomized block design (RBD), the analysis was tested by using F test with a level of 5%. To compare among the treatments with one another treatment used Duncan’s test at 5% level. There is interaction between soaking time and concentration of growth regulators on the parameter Abitonik high seedling age 26 and 31 days after planting, total seedling leaf age 21 days after planting, and germination value. While the concentration of growth regulators Abitonik not provide significant effect on germination of seeds Phinus. Parameters perlakuanlama germination percentage at 60 minutes of immersion (P3) of 59.73% and the concentration of 0.1 cc / l water (K4) of 59.22%
