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

Abstract

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%.
