Pengaruh Gibberellin (GA4) terhadap Waktu Perkecambahan dan Pertumbuhan Tinggi Semai Cendana (Santalum Album Linn.)
Abstract: The hemiparasite
Santalum album Linn. (cendana) grows very slow, in nature the rare and
difficult seeds need stimulation to germinate. Gibberellins (including GA4) are
growth regulators, usually used to increase growth as well as to break seed
dormancy. The objectives of this research were to investigate the influence of
gibberellins on germination percentage and height of cendana growth. Experiment
was laid out in a Completely Randomized Design with 3 replicates of 300 seeds
for germination percentage and 3 replicates of 10 seeds for seedling growth.
Gibberellin was applied as treatment with 100, 300, and 500 ppm. The seed
germination was recorded until 9 weeks, and height of plants measured until 8
months at the greenhouse. The results showed that the addition of gibberellins
at all treatment increased the percentage of germination and caused the seeds
germinated four weeks earlier than the control. In the first 4 months, 500 ppm
gibberellins gave the highest acceleration of germination, afterward all
treatments have relatively the same influences. Gibberellins gave positive
effect on height of cendana growth. After 7 months, the growth decreased
although all gibberellin treatments gave higher growth than the control.
