Abstract

The use of foliar fertilizers and coconut water is potential; foliar fertilizer is the alternative medium and coconut water is the plant growth regulator (PGR) in the banana tissue culture. This study aimed to examine the ability of foliar fertilizer to substitute Murashige and Skoog (MS) media and coconut water as the main source of cytokine. There are two factors in this research. The first factor is the media, which consist of three levels, i.e. fully MS, ½ MS + ½ foliar fertilizer and fully foliar fertilizer. The second factor is the coconut water with four levels of concentration i.e. 50, 100, 150 and 200 ml l-1. The results show that fully formulated foliar fertilizer had not been able to substitute or even compete with a fully MS media, but conversely foliar fertilizer was used to substitute ½ MS media. This can be seen from the parameters of shoot length, leaf length, root number and root length with the highest yield that was found in MS media (8.7, 4.66, 3.33 and 3.23 cm). The 50-100 ml l-1 concentrations of coconut water showed the best results by giving a significant effect on the number of roots and root length. The acclimatization of plantlets in this study was nearly 100%, indicated by the formation of a complete organ.

Abstract

Echinacea (Echinacea purpurea) is an herbaceous plant used as a medicinal raw material. Efforts required simplicia extract of Echinaceae is by increasing the diversity and content of secondary metabolites of Echinaceae through gamma ray irradiation. This study was conducted to determine the morphological characteristics as well as the diversity of growth and results of Echinaceae accession two from the results of gamma ray irradiation. The research was carried out by the Tawangmangu Center for Research and Development of Medicinal Plants and Traditional Medicine and in the Experimental Land of the Faculty of Agriculture, Universitas Sebelas Maret Surakarta, Jumantono Subdistrict, Karanganyar Regency in August 2022-February 2023 with a single plant method and without replication. Data analysis was carried out descriptively and boxplot analysis to see the distribution of data and outlier values. The results showed that the dose of gamma ray irradiation gave rise to new variations in the observed character. Irradiation dose increases diversity in plant growth character and yield. A dose of 40 Gy produced amendment extract yield of 12.32%. A dose of 20 Gy produced total flavonoid level of 0.048%.
