The effect of various natural growth regulatory substances and the origin of stem cuttings on the vegetative growth of white jasmine (Jasminum sambac L.)

Abstract

Jasmine is a native plant of the archipelago in Indonesia. Jasmine (Jasminum sambac L.) is a plant that has many ingredients, including as an ornamental plant, the chemical content of jasmine flowers, namely indole, benzyl, livalyacetat, is believed to be able to treat diseases such as headaches, shortness of breath, fever, excess breast milk and eye pain. Shallot extract is one of the natural growth regulators, namely the auxin group which contains indole and naphthalene compounds which function to stimulate the development of adventitious root meristems. Bean sprouts are one type of vegetable that is commonly used for consumption, easy to obtain, has economic value, and does not have toxic compounds. Bean sprout extract contains growth regulators, namely auxins and cytokinins. Based on the research results, it was found that the concentrations of various natural growth regulators were significantly different with respect to the number of shoots, shoot length, and number of leaves. The best treatment of natural growth regulators was found in shallot extract 50% (Z2). The type of cutting material differed significantly with the number of shoots, shoot length, and number of leaves. The best cutting material treatment was found in the middle of the branch (B2).
