DESKRIPSI KARAKTER MORFOLOGI UBI KAYU PUCUK HIJAU (Manihot essculenta Crantz) ASAL TALUK KUANTAN

Abstract

Cassava (Manihot esculenta crantz) is one of the agricultural commodity that produce tuber for food source in Indonesia. Cassava plants can be developed through plant breeding program that require plasma nuftah with high genetic diversity. This study aimed to describe the morphological characters of “Pucuk Hijau” cassava from Taluk Kuantan. This research was conducted from September 2013 to June 2014 in the garden of Biology ,Faculty of Mathematic and Natural Science University of Riau. Materials used in this study were “Pucuk Hijau” cassava seeds and cow manure. The procedure involves planting and observation of morphological characters. The results showed that the morphological characters of cassava shoots are, green and un-grove stem surface, long ptiole (20 cm), conical-cylidrical tuber shape, light brown outer tuber, thin (1 mm) and purple tuber, with white inner tuber.
