Abstract

The high number of free radicals that are not balanced with the amount of antioxidants in the body triggers oxidative stress. Oxidative stress causes impaired vascular function, damage to proteins and lipids in membrane cell, and nucleic acid (DNA) mutations. Chronic cell damage has a negative effect on tissue that triggers various diseases such as neurodegenerative diseases (Alzheimer's, Parkinson's), cardiovascular diseases (hypertension, arteriosclerosis, and others), cataracts, retinal damage, maculopathy, rheumatoid arthritis, asthma, stroke, diabetes mellitus , immunodepression, cancer, aging, hyperoxia, dermatitis, and others. The application of a healthy lifestyle for example by consuming food sources of bioactive compounds can minimize health risks. Rice is the staple food of the Indonesian people. Some types of rice contain red and black pigments which are known to have high antioxidant activity compared to white rice. The pigment comes from anthocyanin and proanthocyanidin. Various studies in vitro and in vivo prove that anthocyanin and proantocyanidine act as antioxidants and potency as a preventative for various diseases such as cardiovascular, diabetes mellitus, and etc.

Abstract

A study aimed to determine the effect of coconut water on the growth of Chrysanthemum explants was conducted. The study was carried out in the form of factorial experiments at Tissue Culture Laboratory, Department of Agronomy, Faculty of Agriculture, Hasanuddin University from December 2022 to March 2023. Media used was Murashige and Skoog (MS) added with three dose of coconut water, 100, 200, and 300 ml, respectively. Plantlets of five varieties of Chrysanthemum, Pinka Pinky, White Bakardy, Maruta, Kineta, and Dera obtained from Tissue Culture Laboratory, Horticultural Plant Seed Center, Bonto-bonto District, Gowa Regency. The explants were planted in Murashige and Skoog (MS) media containing the coconut water according to the treatments. Each combination of treatment was repeated three times. Results show that addition of 100 ml coconut water into the MS media was the best dose for plantlets growth indicated by earliest shoot emergence (9.04 days) and plantlet formation (9.25 days), and highest average number of leaves (15.00 leaves). The coconut water treatment of 200 ml showed the highest average number of roots (14.67 roots). Variation in responses between varieties were observed.
