Pengaruh Pemberian ZPT Alami Bawangmerah (Alium cepa L.) dan Air Kelapa (Cocus cucifera L.) Terhadap Pertumbuhan Stek Pucuk Jambu Air Citra (Syzigium aqueum Burm)

Abstract

The fruit of the Citra Water Apple plant is quite popular with the public because of its sweet, savory, and legit taste. The demand for the fruit in the market is quite high, which also encourages the provision of seeds for people who want to grow this Citra Water Apple plant. One method is vegetative propagation of seeds in the form of cuttings. Vegetative propagation by cuttings requires ZPT stimulation because propagation by cuttings is constrained by its rather slow growth, the use of natural ZPT is expected to stimulate the growth of cuttings in the form of leaf shoots and roots. This study used a non-factorial completely randomized design (CRD) method with 7 treatment levels, the first treatment was a control, then the administration of 0.5%, 1%, 1.5% shallot extract, then 25%, 35% and 45% coconut water. The parameters observed were when the shoots broke, the number of shoots, the length of the shoots, the percentage of shoots, the length of the roots and the percentage of living cuttings. Furthermore, the results of each treatment level will be analyzed statistically. The results of the research that has been conducted show that the provision of several natural ZPTs of Shallots and Coconut Water on the growth of Citra Water Apple Cuttings (Syzigium Aqueum Burm) showed no significant difference, because Fcount was smaller than Ftable for each treatment given. So, the provision of natural ZPTs of shallots with concentrations of 0.5%, 1%, 1.5%, and natural ZPTs of coconut water 25%, 35%, 45% did not have a significant effect on the growth acceleration of Citra Water Apple Cuttings (Syzigium Aqueum Burm).
