Abstract

Rice Blast has been known as the main disease on paddy which has high severity leading to economic loss. Exploring rice resistance can be an effective way to improve productivity and prosperity toward this staple crop. This study aims to determine several local varieties which have potential for productions and resistances. This study used factorial randomized block design (RBD) consisting of 2 factors including plant spacing (25 x 25 cm; 25 x 30 cm; 25 x 40 cm); Upland rice variety MSP 17, Sigambiri Merah, Hamparan Perak and Kambiri Lumat. The results of the study reveal that variety has a significant effect on disease intensity especially Sigambiri Merah but not on Kembiri Lumat. However, there is no significant effect of spacing on blast intensity except in grain weight. Conclusion of this research was the varieties (V) selection of red upland rice is the best strategy to improve rice resistance toward blast disease. Keywords:  Disease density, Paddy, Staple Crop.

Abstract

p Penelitian ini bertujuan untuk membandingkan kadar senyawa metabolit sekunder pada daun pisang Kepok Kuning em Musa paradisiaca em em L em hasil kultur jaringan dengan tanaman konvensional Sampel daun pisang kultur jaringan diperoleh dari tanaman berumur 4 bulan yang ditanam di rumah kaca sedangkan sampel konvensional berasal dari kebun rakyat dengan umur tanaman 4 bulan Sampel dikeringkan dengan menggunakan oven pada suhu 50 C selama 10 menit kemudian sampel dikeluarkan dan didinginkan kemudian dihaluskan kemudian diekstraksi menggunakan metode maserasi dengan pelarut etanol 96 Persen Hasil analisis kualitatif diperoleh senyawa flavonoid fenol total tanin saponin dan alkaloid Hasil penelitian menunjukkan hasil analisis kuantitatif untuk kadar flavonoid fenol total tanin dan alkaloid pada daun pisang hasil kultur jaringan lebih tinggi dibanding tanaman konvensional masing masing meningkat sebesar 15 5 Persen 11 8 Persen 21 6 Persen dan 15 9 Persen Sebaliknya kadar saponin pada kultur jaringan lebih rendah dibanding konvensional dengan selisih 6 3 Persen Temuan ini menunjukkan bahwa teknik kultur jaringan dapat memengaruhi akumulasi metabolit sekunder pada daun pisang sehingga berpotensi menjadi strategi alternatif dalam produksi senyawa bioaktif p
