PERBANDINGAN KANDUNGAN HORMON ENDOGENOUS PADA BEBERAPA TANAMAN

Indonesia's flora germplasm diversity can be used as a potential source of natural growth regulators. The study's goal was to compare the auxin, cytokinin, and gibberellin content of various horticultural plant extracts: onion tubers (Allium ascalonicum), a banana weevil (Musa x paradisiaca), Moringa leaves (Moringa oleifera), sweet corn seeds (Zea mays), and green bean sprouts (Vigna radiata). The research was carried out at Jenderal Sudirman University's Research Laboratory from June 2019 to February 2020. The sample was prepared in the Chemical Laboratory of the Ministry of Agriculture's Postharvest Center in Bogor for analysis of auxin (IAA/Indole Acetic Acid), cytokinins (kinetin and zeatin), and gibberellins (GA3/ Gibberellic Acid). RAL (Completely Randomized Design) was used as the experimental design. The F test and Duncan Multiple Range Test (DMRT) were used to further examine the data. Endogenous hormone content was determined in five ingredients: shallot bulbs (Allium ascalonicum), banana hump (Musa x paradisiaca), Moringa leaves (Moringa oleifera), sweet corn seeds (Zea mays), and green bean sprouts (Vigna radiata). Moringa leaves had the highest IAA content, 662.17 ppm, according to the findings. Similarly, the highest kinetin content was found in banana weevil and Moringa leaves, with 178.82 ppm and 161.37 ppm, respectively. Shallot bulbs had the highest GA3 content, at 594.12 ppm. This demonstrates that the four plant types can be used as sources of plant hormones.Keanekaragamaan plasma nutfah flora di Indonesia dapat digunakan sebagai sumber potensial zat pengatur tumbuh alami. Tujuan penelitian untuk mengetahui perbedaan kandungan auksin, sitokinin, dan giberelin berbagai ekstrak bahan organik: umbi bawang merah, (Allium ascalonicum), bonggol pisang (Musa x paradisiaca), daun kelor (Moringa oleifera), biji jagung manis (Zea mays), dan kecambah kacang hijau (Vigna radiata). Penelitian dilakukan pada Juni 2019 sampai Februari 2020 di Laboratorium riset, Universitas Jenderal Soedirman untuk preparasi sampel dan Laboratorium kimia, Balai Besar Pascapanen, Kementerian Pertanian, Bogor untuk analisis kandungan auksin (IAA/Indole Acetid Acid), sitokinin (kinetin dan zeatin), dan giberelin (GA3/ Gibberellic Acid). Rancangan percobaan yang digunakan RAL (Rancangan Acak Lengkap) dengan lima perlakuan dan empat ulangan. Data dianalisis dengan uji F dan uji lanjut Duncan Multiple Range Test (DMRT). Lima bahan yang dianalisis kandungan hormon endogenous yaitu umbi bawang merah (Allium ascalonicum), bonggol pisang (Musa x paradisiaca), daun kelor (Moringa oleifera), biji jagung manis (Zea mays), dan kecambah kacang hijau (Vigna radiata). Hasil penelitian menunjukkan bahwa daun kelor mempunyai kandungan IAA yang paling tinggi 662,17 ppm diikuti bawang merah 251,76 ppm; kecambah kacang hijau 227,37 ppm; bonggol pisang 94,20 ppm; dan biji jagung 62,20 ppm. Bonggol pisang dan daun kelor mempunyai kandungan kinetin terbanyak 178,82 ppm dan 161,37 ppm diikuti biji jagung 128,25 ppm; kecambah kacang hijau 125 ppm; dan umbi bawang merah 75,54 ppm. Kandungan zeatin terbanyak dalam bonggol pisang 138,53 ppm diikuti kecambah kacang hijau 95,45 ppm; daun kelor 66,5 ppm; biji jagung 45,76 ppm, dan umbi bawang merah 23,77 ppm. Kandungan GA3 terbanyak terdapat pada umbi bawang merah 594,12 ppm; diikuti daun kelor 417,88 ppm; kecambah kacang hijau 371,56 ppm; biji jagung manis 269,75 ppm; dan bonggol pisang 104,12 ppm
