Uji Vigor Benih Cabai Rawit (Capsicum sp.) dengan Metode Radicle Emergence menggunakan Analisis Citra Digital

Abstract

The application of digital image processing technology with imageJ software at seed vigour test (Radicle Emergence test) is to obtain quantitative data of seed diameter/length, and radicle length at each observation period. Observations of the radicle emergence were carried out every three hours interval starting from 72 to 126 hours after planting. This research was conducted by observing the number of seeds that have four categories of radicle length 1mm, 2mm, 50% seed length (pjb), and seed length (pjb), and performed correlation analysis on several benchmarks of seed quality in the laboratory ( germination, vigor index, maximum growth potential, and growth rate) and in nurseries (number of leaves, plant height, and percentage of growth). Based on the test results, the radicle length category 1mm (84 hour) and 2mm (93 hour) had a strong correlation with the seed vigor benchmark (vigor index, growth rate, and percentage of growth in nursery), while the radicle length category ≥ 50% pjb and ≥ pjb only had a strong correlation with vigor index and growth rate at the same time.
