PEMBERIAN ZAT PENGATUR TUMBUH AUKSIN DENGAN BERBAGAI KONSENTRASI PADA BIBIT KARET (Hevea brasiliensis) STUM MATA TIDUR KLON PB 260
Abstract: This research aimed
to find out the influence on giving auksin plant growth regulator with various
concentrations and to obtain the best concentration for the growth of budded
rubber stum. This research was conducted at experimental farm of Farming Faculty
of Riau University at Bina Widya st Km 12,5, Simpang Baru, Tampan, Pekanbaru.
This research was carried out experimentally with Complete Random Design (CRD),
the treatments given were the auksin plant growth regulator concentration which
consisted of several stages (P0) without giving auksin plant growth regulator,
(P1) concentration of 25 mg/0,5 ml water, (P2) concentration of 50 mg/ 0,5 ml
water, (P3) concentration of 75 mg/ 0,5 ml water. Every treatment consisted of
5 repetition so that it was obtained 20 experiment units. Every experiment unit
consisted of 3 plants and 2 plants were being sample. The observed parameters
were that the time of buds emerging, the amount of leaves, the diameter of buds
and the wide of buds. The obtained data was analyzed statistically with
analysis of varience and continued to Duncan’s New Multiple Range Test (DNMRT)
at 5% degree. The concentration of plant growth regulator 50 mg/0,5 ml water
had the best effect for the growth of giving budded rubber stum (Hevea
brasiliensis) clone PB 260.
