PENGUJIAN BEBERAPA KONSENTRASI GIBERELIN PADA BIBIT KELAPA SAWIT (Elaeis guineensis Jacq.) DI PRE NURSERY YANG MENGALAMI CEKAMAN GENANGAN AIR
Abstract: Seedling is a plant
material which is very important in the development of the palm oil industry. Quality of
seedlings will determine the success of oil palm cultivation. The uncertain
climate change caused many oil palm nursery are flooding. This stage of hypoxia
or anoxia caused plant growth stress. Therefore has been tested multiple
giberelin concentrations and flooding against oil palm seedlings on pre
nurseries. This research aims to maintaining quality of oil palm seedlings of
waterlogging stress by providing some gibberellin concentration. This research
was conducted at the experiment station of Agriculture Faculty University of
Riau, Pekanbaru from June to September 2015. The experiment using the
completely randomized factorial design 3 x 3 and 3 replications. The first
factor are g0 = without gibberellin, g1 = 150 ppm gibberellin and g2 = 300 ppm
gibberellin, and the second factor is duration of waterlogging stress. There
are w0 = 0 days, w1 = 25 days and w2 = 50 days. The results is no interaction of gibberellin
concentration and flooding stress to oil palm seedling. The higher
concentration of gibberellin given caused higher seedlings, and the growth of
diameter rod and adventitious roots was affected by flooding.
