Ethyl methanesulfonate ems
WebEthyl methanesulfonate (EMS) is a widely used chemical mutagen in plants as it gives a high frequency of point mutations. Hence, this study aimed to determine the lethal concentration 50 (LC 50 ) of EMS and the mutagenic effects of EMS on growth characteristics and morphological variations of N. cadamba derived from nodal explants. WebSalvia coccinea is a valuable flowering annual that attracts hummingbirds and bees to the garden, but few cultivars are commercially available. There is a limited range of petal colors and no leaf variegation. This research aimed to improve the ornamental value of S. coccinea by inducing mutations with ethyl methanesulfonate (EMS). The standard, red-flowered …
