Keragaman Karakter Morfologis Garut (Marantha arundinaceae L.)

Abstract

Morphological Characteristics Variability of Arrowroot (Marantha arundinaceae L.). The arrowroot has been recognized by most society member of Indonesia as a source of potential foodstuf. The arrowroot has low glicemic index, and high carbohydrate content, high quality of flour and can replace position of wheat flour as food material and industry. Evaluation and characterization are needed to get informations of superior characteristic of arrowroot as source of genetic variability to develop promising new arrowroot varieties. The result showed that the morphological characteristic of 20 arrowroot accecions were not different on the qualitative characteristics. The characteristics of leaf colour, stem and stalk leaf colour, and white colour of tuber were not different among arrowroot accecions. The quantitative characteristics of tuber or rhizomes type (tuber length and tuber circle), plant height, number of tiller/hill, total leaf/main stem, leaf length and leaf width among accecions had low variability. The tuber weight per hill had positive correlation with plant height, number of leaf, tuber length and tuber circle and negative correlation with leaf length, leaf width and stalk length leaf.Keywords: Variability, morphological, arrowroot ABSTRAK Garut (Marantha arundinaceae L.) merupakan sumber pangan yang potensial bagi sebagian masyarakat di Indonesia. Garut memiliki indeks glikemik rendah dan kandungan karbohidrat tinggi. Tepung garut dapat menggantikan terigu sebagai bahan makanan dan industri. Evaluasi dan karakterisasi garut perlu dilakukan untuk memperoleh informasi sifat-sifat unggul untuk dapat digunakan dalam perakitan varietas unggul. Hasil evaluasi 20 aksesi garut yang dikarakterisasi menunjukan tidak ada perbedaan morfologis sifat kualitatif. Warna daun, pelepah dan tangkai daun, bentuk daun, bentuk dan warna umbi memiliki kesamaan antaraksesi. Karakter kuantitatif pada bentuk umbi (panjang dan lingkar umbi), tinggi tanaman, jumlah anakan/rumpun, jumlah daun pada batang utama, panjang dan lebar daun antar aksesi plasma nutfah garut memiliki keragaman yang sempit. Hasil analisis menunjukkan bahwa bobot umbi per rumpun berkorelasi positif dengan tinggi tanaman, jumlah daun, panjang, lingkar umbi, dan berkorelasi negatif dengan panjang daun, lebar daun, dan panjang tangkai daun.

Otentikasi Toge Goreng Sebagai Makanan Tradisional Khas Kota Bogor

“…Daun patat merupakan kekhasan pengemasan taoge goreng yang dibungkus (Gambar 5). Daun patat atau garut dengan nama ilmiah Maranta arundinaceae merupakan tumbuhan herba berumpun dengan perakaran dangkal, daun muda berwarna hijau muda, serta daun tua berwarna hijau, berbentuk oval dengan ukuran panjang berkisar antara 19-26 cm serta lebar 7-9 cm (Suhartini & Hadiatmi, 2011). Daun patat memang dikenal sebagai pembungkus makanan.…”

Physiological Response and Photosynthate Distribution of West Indian Arrowroot at Different Altitudes

“…Application of fertilizers during planting were manure and Super Phosphate 36, 1/3 dosage of urea, and 1/3 dosage of KCl. Urea and KCl (2/3 dosage) were given at 3.5 month after planting (MAP) (Suhartini & Hadiatmi, 2011).…”

Cytomorphological characteristics evaluation of the third generation of arrowroot plant (Maranta arundinacea L.) radiated by gamma ray

“…Arrowroot is a low light adaptive plant, under the light intensity 7400 lux (27% full light), the number of leaves and tillers were not different under full light, while the plant is higher (Kusmiyati, 2013). According to Suhartini & Hadiatmi (2011), arrowroot plants are plants that would grow 188 optimally under tree stands with minimum light intensity. The results of further tests on the effect of accession on plant height presented in Table 4.…”
