INDUKSI KETAHANAN DAN PERTUMBUHAN BIBIT KELAPA SAWIT DENGAN BAHAN PENGINDUKSI BERBEDA JAMUR Trichoderma virens ENDOFIT TERHADAP PENYAKIT BUSUK BATANG ATAS
Abstract: The Diseases found
in oil palm plantations is the Upper Stem Rot (BBA) caused by pathogens
Ganoderma sp. The alternatives that can used in controlling the disease BBA is
by use endophyte microorganisms derived from plant tissue one of the
Trichoderma virens endophyte. This study aimed to determine the effect of the
administration of the different material inducer T. virens endophyte and get
the best inducers ingredient in promoting growth and controlling upper stem rot
disease on the oil palm seedlings, This research has been conducted in the
experimental garden of the Faculty of Agriculture, State University of Riau,
Industrial Business Unit Biofertilizer and Biopesticides University of Riau,
Laboratory of Soil Science, Faculty of Agriculture, University of Riau, the
Laboratory photomicrography and Laboratory of Biochemistry, Faculty of
Mathematics and Natural Sciences, University of Riau, on Campus Binawidya km
12.5 Baru Simpang Village District of Handsome Pekanbaru. This study was
conducted in May 2016 to November 2016. This study was conducted experiments using
completely randomized design with 3 treatments and 7 replications so that
obtained 21 experimental units. Data were analyzed statistically by ANOVA and
tested with LSD at 5% level. The results showed that treatment of inducing
materials in the form of T. virens endophyte suspension showed is the best
treatment to be better increase plant height, stem diameter, root volume, and
tend to be higher in prolong the incubation period, reduce the intensity of the
disease, and increases the concentration of salicylic acid in the leaves of oil
palm seedlings.
