Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole

Abstract

Talas putih (Xanthosoma sp) berpotensi sebagai sumber pangan alternatif, namun dalam pemanfaatannya terdapat kendala berupa senyawa anti gizi berupa kalsium oksalat. Cahaya mempengaruhi pertumbuhan tanaman talas putih dan kandungan kalsium oksalat pada umbinya. Penelitian ini bertujuan untuk mengetahui pengaruh intensitas cahaya terhadap pertumbuhan dan kandungan kalsium oksalat, untuk mengetahui tingkat intensitas cahaya yang optimal terhadap pertumbuhan tanaman talas putih, dan untuk mengetahui intensitas cahaya yang optimal untuk menurunkan kadar kalsium oksalat pada tanaman talas putih. Penelitian ini telah dilaksanakan di kebun percobaan Fakultas Pertanian Universitas Andalas, Laboratorium Fisiologi Tumbuhan, dan di Laboratorium Non Ruminansia Fakultas Peternakan Universitas Andalas Padang. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 taraf, tanpa naungan (0%), naungan 25%, naungan 50%, dan naungan 75%, dengan 3 ulangan. Data dianalisis menggunakan uji F pada taraf 5% dan menggunakan Duncant Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa intensitas cahaya berpengaruh terhadap pertumbuhan tanaman talas putih serta kandungan karbohidrat dan kalsium oksalat. Tingkat naungan 0% (tanpa naungan) menghasilkan kandungan karbohidrat tertinggi dan bobot umbi terberat. Penggunaan naungan 75% menghasilkan pertumbuhan pelepah tertinggi dan kandungan kalsium oksalat terendah.
