PENGARUH KONSENTRASI IBA (Indole Butyric Acid) DAN LAMA PENCELUPAN STEK TERHADAP PERTUMBUHAN GERMINATIF RUMPUT RAJA (Pennisetum purpurephoides)

Abstrak

King grass is parenenial plant that grow slower then elephant grass.  The growth and development of the  plant breed effected by development of the clone so that some efforts must be taken  to stimulate germinative  development of king grass. The research purposed to know how for the level of IBA  consentration and immersion period of the slip of plant has an effect  toward the growth of germination of king grass. Complete randomizet design of factorial type 3 x 3 and Duncan’s multiple range test, were used in the experiment. The treatments  were used  in the eksperiment: K1 (100 ppm of concentration), K2 (200 ppm of concentration), K3 (300 ppm of concentration), W1 (one hours of immersion  period), W2 (two hours of immersion  period), W3 (Three hours of immersion  period). The result of this research  showed that amount the treatments gave significant effect to the percentation of buds, number of buds, height of plant, number of roots, length of root. Nevertheless, there  was an inccclination that the more  the height of consentration  level was given, the result would better than the research. It can be concluded that the level of IBA consentration and immersion period  had a positive effect influences which from the  average result obtained K3W3 gave the heighest percentation of buds appear, number of buds, height of plant and length of roots. While persentation  of buds to appear, number of buds, height of buds and the lowest roots length founded in K1W1.
