POTENSI EKSTRAK DAUN PINUS (Pinus merkusii Jungh. et de Vriese) SEBAGAI BIOHERBISIDA PENGHAMBAT PERKECAMBAHAN Echinochloa colonum L. DAN Amaranthus viridis.
Abstract: The allelopathic
substances are organic agents which are produced and released by a plant that
cause alteration on the neighboring plants. The characteristics of
allelochemicals usually inhibit germination of other species and sometime will
reduce growth of the other species which associate with the producer of
allelochemicals. The mechanism of allelochemicals can be used to suppress a
germination of Echinochloa colonum L. and Amaranthus viridis L. These plants
are weeds species of rice. The aims of this research were to study the
allelochemicals effect from the leaf of pines (Pinus merkusii Jungh. et de
Vriese) on germination of Echinochloa colonum L. and Amaranthus viridis L.. The
experimental design used Completely Randomized Design with five replicates for
each concentration (0, 250, 500, 750, 1000 ppm). The result which was analyzed
with One-Way Analyze of Varians (ANOVA) indicated that giving a pine leaf
extracts had an inhibitor effect on germination of E. colonum L. and A. viridis
L.
