Pengaruh Geotropisme dan Hidrotropisme terhadap Panjang dan Kemunculan Radikula pada Kacang Hijau (Vigna radiata L) dengan Metode Selang Tunggal

Geotropism is the movement of plants influenced by the Earth's gravitational force. Hydrotropism plays an important role for plants by helping to improve access to water, a vital factor for successful plant growth. Mung bean plants are rooted by their root system which is divided into two types, mesophytes and xerophytes. Growth affects the length of mung bean radicle without significantly affecting radicle emergence. This study was conducted with experimental methods using two groups of data: quantitative for radicle length and percentage of radicle emergence; and qualitative data for the direction of radicle growth. Based on the results of the study, it was found that the medium on dry-dry the direction of radicle growth in geotropism samples was positive, namely the direction of the roots towards the center of the earth While wet-dry treated with water limited by cotton, the radicle in geotropism samples was negative, namely the direction of the roots against gratification This is due to the roots being treated with water from the top of the hose which is limited by cotton, so that the roots go towards the water source.
