Morphological Diversity of Double Petal Telang (Clitoria ternatea L.) in Several Flower Colors

Abstract

Telang is a plant that grows wild and is cultivated by the people of Indonesia. Telang flowers originate from Ternate Island, Maluku, Indonesia. The most widely used part of Telang, especially in food coloring, is the flower, where Telang flowers can produce a blue color. This study aims to assess the diversity of four types of double-petal Telang flowers based on plant morphology. This study used a Non-Factorial Randomized Group Design (RAK) with treatments in 4 colors of double-petal Telang flowers. The number of replications required was 5 replications, so there were 20 experimental blocks, each experimental block was planted with 3 plants, the number of samples taken from each experimental block was 2 plants and 3 flower samples were taken from each plant. Morphological observations were made directly in the field; the morphological characters observed included varieties and generative. For each color 10 plants were selected. The results of this study show that some types of Telang showed good growth, such as plant height, and then, for the generative period, no significant difference was produced between the types of Telang. Some of the morphology of leaves and flowers have visible similarities. This study's conclusion is based on observing vegetative, generative, and morphological characters of several types of Telang. The observations found that in the vegetative period, some Telang tended to grow fast, but the purple and blue Telang had the highest plant height. Then, in the generative period, the average observation of several types of Telang was not significantly different. The morphology of Telang itself also still has similarities, such as leaf morphology and Telang flowers.
