UJI INFEKTIVITAS Scleroderma spp. PADA SEMAI Shorea
selarrica (DC.) Blume DAN Hopea odorata (Roxb.)
ABSTRACT 1
Infection test of Scleroderma geaster, Scleroderma sirmamariense, Scleroderma
columnare and Scleroderma sp. to Shorea selanica seedlings has been studied under
green house conditions. Those myconhizal lirngi, except Scleroderma sp. were also
tested to Hopea odorara seedlings. Root mycorrhizal percentage and formation of
mantel and Hartigfs net structures were investigated.
The objective of the research was to find out the most infective Scleroderma
mycorrhizal iimgi to Shorea selanica and Hopea odorara seedlings.
_ Root structural analysis of 3 months inoculated roots showed that there were
mycorrhizal colonization in Shorea selanica and Hopea odoraia rooting system but
mantel and I-Iartig?s net structures were not formed yet. These structures were
completely fonned 4 months after inoculation. Root structure observation showed that
Scleroderma spp. colonized and infected well the root system of Shorea selarzica and
Hopea odorara seedlings. The percentage of mycorrhizal roots was 13.75 % to 42.50 %
for Shorea selanica seedlings and 14.17 % to 59.17 % for Hopea odorata. Hartig?s net
structures were formed in between two radially elongated epidermis cells.
PENDAHULUAN
Tanaman meranti (Dqoterocarpaceae) merupakan salah satu pohon hutan tropis
yang mutlak rnembutuhkan mikoriza terutama pada tingkat semai (Yasman, 1997).
Mikoriza adalah suatu asosiasi yang sepenuhnya simbiosis dan menghasilkan suatu sifat
morfologi yang baru dan konsisten dalam proses asosiasinya serta mendatangkan
kcuntungan untuk lcedua organisme tersebut (Harley & Smith, 1983). Scleroderma
spp. mempakan cendawan elctomikoriza yang sexing ditemukan berasosiasi dengan jenis-
jenis tanaman dan famili Dipterocarpaceae, Pinaceae dan Gnetaceae. Sifat khusus dari
ektomikoriza adalah adanya struktur mantel yang terbcntuk dad jalinan hifa, yang
menetap pada permukaan akar dan Hartig-net yang terdapat di antara sel epidermis dan
