SKRIPSI PENGARUH LAMA PERENDAMAN BENIH DALAM BEBERAPA KADAR GIBBERELLIN TERHADAP PERTUMBUHAN BIBIT KARET
ABSTRACT
An experiment that examines abour the influence of duration of soaking of seed In Bome concetration of gibberellin to the growth of rubber seed (Hevea brasil1- ensin MA), has been done in Potrobangsan village, North Magelang sub district Magelang, on the altitude 376 metres and regosol soil tipe, pH to 7.
The design of the experiment based on factorial ex- periment WAB arranged by Completly Randomized Design (CDR) using two treatment and four replication. The first treatment, concentration of gibberellin 0 ppm, 50 ppm, 100 ppm and 150 ppm. The second treatment. duration of soaking of the seed 12 hours, 24 hours and 36 hours.
The result analysis show that the treatment of seed with the duration of soaking 24 hours at concentration 100 ppm giving better result to: germination seed the height of seedlings, number of leaves, length of roote, number of lateral roots, amoun of reesh weight and the dry weight of seedling compare with the control.
