POTENSI EKSTRAK DAUN BAMBU APUS (GIGANTOCHLOA APUS KURZ)SEBAGAI BIOHERBISIDA PENGHAMBAT PERKECAMBAHAN BIJI DAN PERTUMBUHAN GULMA RUMPUT GRINTING (CYNODON DACTYLON(L.) PERS)
ABSTRACT: Spring
bamboo(GigantochloaapusKurz)leaves have allelochemicalcompounds such as phenol
and flavonoid that able to obstruct other plant growth, so that they have
potentiality to be used as bioherbicide. The aim of this research war to
coqnize the effective concentrations of spring bamboo leaves extract to
obstruct seed germination and growth of devil’s grass (Cynodon dactylon (L.)
Pers). The research was conducted for 7 months started from May to December
2014 in Biology Laboratory, Biology Greenhouse of Math and Science Faculty, and
Forest products Tecnology Laboratory of Forestry Faculty of Tanjungpura
University. The method of this research utilized the completely randomized
design (CRD) with 5 treatments and 5 replications. The concentrations of spring
bamboo leaves extract used in this research were 0 g/ml, 0,17 g/ml, 0, 42 g/ml,
0,81 g/ml and 1,5 g/ml. The Result of this research shows that the
administration of spring bamboo leaves extract can obstruct the seed
germination and growt of devil’s grass. The lowest effective concentration that
can obstruct seed germination of devil’s grass is 0,81 g/ml. The lowest
effective concentration that can obstruct the growt of devil’s grass is 0,17
g/ml.
