Aplikasi ZPT Rebung Bambu pada Pematahan Dormansi Benih Sacha Inchi (Plukenetia volubilis L.)

This research aims to determine the effect of bamboo shoot extract concentration on the viability and vigor of sacha inchi (Plukeneltia volubilis L.) seeds. The research was carried out at the Faculty of Agribusiness and Agricultural Engineering, Subang University Campus, Nyimplung Village, Wanareja Village, Subang District, Subang Regency, West Java Province, at an altitude of 79 meters above sea level with an average air temperature of around 28-33℃. This research was conducted from 15 December 2022 to 6 February 2023. The method used in this research was a simple Randomized Block Design (RAK) consisting of 4 treatments, each treatment repeated 6 times: 0 ml/liter (R0), 2.25 ml/liter (R1), 4.5 ml/liter (R2), 6.75 ml/liter (R3). The results of this research show that the concentration of bamboo shoot extract influences all parameters carried out, namely germination capacity, normal sprouts, dead seeds, plant height, number of leaves, and stem diameter he use of bamboo shoot extract in the R2 treatment with a concentration of 4.5 ml/L (R2) gives the best effect on normal sprout parameters in sacha inchi plants.
