The use of Indole Butyric Acid on the growth of dragon fruit plant stem cuttings

Abstract. Hernosa SP, Tampubolon SDR, Siregar LAM. 2022. The use of Indole Butyric Acid on the growth dragon fruit plant stem cuttings. Nusantara Bioscience 14: 211-216. difficulty root cuttings is affected by rot; one way to increase a regulator, namely (IBA), which used stimulate rootstock This research was conducted in Sidorukun Village, Pangkatan Sub-district, Labuhan Batu District, North Sumatra, Indonesia, at an altitude ± 40 m above sea level, from June October 2020. design randomized block with five treatments. concentration IBA hormone consists B0 : 0 ppm, B1: 4,500 B2: 5,500 B3: 6,500 B4: 7,500 and replicates, so entire experimental plot 25. Parameters observed were percentage shoot emergence, age length (cm), fresh weight (g), dry volume (g). Data analysis linear model followed Duncan's test. It known that administration butyric acid (IBA) significantly parameters number shoots, length, weight, volume, weight. However, it did not affect parameters, namely, On other hand, B4 (7,500 ppm) gave better growth,
