Abstract

Bunga melati putih memiliki potensi ekonomi dan social yang besar bagi masyarakat Indonesia khususnya dan dunia umumnya. Kebutuhan melati putih terus meningkat, namun produksi bunga melati putih di Indonesia baru mampu memenuhi sekitar 20% dari kebutuhan melati di pasaran dunia. Untuk itu diperlukan upaya untuk meningkat kuantitas dan kualitas produksi bunga. Pemanfaatan Zat Penghambat Tumbuh merupakan salah satu solusi untuk meningkatkan produksi bunga melati putih. Salah satu Zat Penghambat Tumbuh yang biasa digunakan adalah paclobutrazol. Sehubungan dengan itu maka dilakukan penelitian dengan judul “ Induksi Pemekaran Bunga (Anthesis) Tanaman melati putih (Jasminum sambac L. W. Ait) dengan pemberian paclobutrazol pada beberapa konsentrasi. “ Penelitian ini dilakukan pada bulan Maret sampai Juni di greenhouse STKIP PGRI Sumatera Barat. Rancangan  percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) yang terdiri dari 6 perlakuan dan 4 ulangan.  Terdiri dari perlakuanA= control, B=200 ppm, C=400 ppm, D= 600 ppm, E= 800 ppm, E= 1000 ppm. Hasil penelitian menunjukkan bahwa pemberian paclobutrazol pada beberapa konsentrasi tidak memberikan pengaruh terhadap waktu muncul kuncup bunga, waktu mekar bunga (anthesis), dan jumlah bunga melati putih

Abstract

Male banana is one of the varieties of bananas that becomes a main commodity of West Sumatra. As a main commodity, then growth, quality and productivity need to be maintained and improved. Soil microbial technology application, such as the development of biological agents of Fungi Mycorrhizae Fungi (AMF), is one of the strategies need to be tested and developed to support the development of a national program of healthy banana seedlings as well as issues of pressing environmental preservation based fertilizers and chemical pesticides. This research was conducted at the Laboratory of Plant Physiology and tissue culture and greenhouse of Faculty of Agriculture, University of Andalas, Padang. This research used an experimental method arranged in a factorial completely-randomized design consisting of two factors with three replications. Factor A: Dose mycorrhizae (A0 = no inoculation, A1 = 5 g inoculant FMA PU10, A2 = 10 g inoculant FMA PU10, A3 = 15 g inoculant PU10, A4 = 20 g inoculant PU10. Factor B: Timing of phosphate (B0 = 0 HSI inoculant FMA PU10 B1 = 10 HSI inoculant FMA PU10, B2 = 20 HSI inoculant FMA PU10, B3 = 30 HSI inoculant FMA PU10, B4 = 40 HSI inoculant FMA PU10). The research shows that inoculation of inoculant FMA on different doses give a significant effect on the percentage of male banana seedling of root colonization. Where dosing 10 grams (A2) shows that the highest root colonization percentage compared with other treatments equals to 53. 33%. The provision of phosphate on 30th day of  HSI Mycorrhizae shows that the highest percentage of colonization is 45.55%.
