The phenotypic appeal of lily (Lilium longiflorum Thunb.) prompted mutation by colchicine

Abstract

One of the efforts to assemble high yielding varieties is to use a chemical mutation method, such as colchicine. The objective of this study was to examine the phenotypic appeal of lily convinced by colchicine to acquire a current application and interval of the period for soaked colchicine. The research was steered in the investigational research place of Institute for Vegetable Research (IIVR) at Tongkoh, Sub-District Dolat Rakyat, District Karo, North Sumatera, and Plant Tissue Culture Laboratory, Agriculture Faculty, Universitas Sumatera Utara, from July 2019 up to March 2020. The research castoff Randomized Block Design technique (Factorial-RBD) by two factorials, i.e.: application of colchicine (0, 100, 200, and 300 ppm) and the interval of time for soaked colchicine (3, 6, 9, and 12 h). The constraint experimental was the plant tallness, the span of bud after flourishing, and the width of bloom. The outcome of this study indicated the concentration of colchicine hip 300 ppm (K3) devours pointedly influenced on the plant tallness in the first week until sixth weeks when planting and the concentration of colchicine in 100 ppm (K1) has considerably influenced on the size of bud after flowering and the span of bloom.
