KETAHANAN SEMAI AKASIA (Acacia mangium) PADA VARIASI UMUR TERHADAP INFEKSI Ganoderma spp.
Abstract: Ganoderma is a
pathogen cause rot root desease which attack the plant with a wide range of
ages. It is necessary to do research to know level of acacia plant resistance
at1 month and 3 months on Ganoderma infection. The research aims was to
determine theeffect of Ganodermainfecton on acacia resistance at the age of 1
month and 3 month.The research used a factorial completely randomized design
which consist of twotreatment factor namely Ganoderma and age of seedling.
Ganoderma treatment is control (G0), Ganoderma from palm oil (G1), Ganoderma
from the acacia host (G2),Ganoderma from the rubber host (G3). The age
treatment of seedling is 1 month acaciaseedlings and 3 month acacia seedlings.
Each treatment was repeated 3 times with 4plants per replication resulting in
96 experimental units. Research observation variableis desease severty index by
in vivo and dry weight of the plant. The result showedGanoderma is pathogenic
in 1 month acacia seedling with a severity index value of 0,6and 3 month acacia
seedling with a severity index value of 1. Dry weight of plant control treatment
of acacia seedling age 3 months higher than other treatment that is11,27. 3
month old acacia seedlings are more susceptible and rapidly cause symptomsof
Ganoderma infection than 1 month old acacia seedlings.
