Abstract

Abstract. Aisyah SI, Saraswati RAM, Yudha YS, Nurcholis W. 2022. The diversity of agromorphological characters of Portulaca grandiflorain the MV8 population deriving from recurrent irradiation. Biodiversitas 23: 4432-4439. A multipurpose ornamental plant, Portulaca grandiflora has the value of attractiveness and uniqueness, which lies in various agromorphological characters, primarily in flowers. The potential of P. grandiflora in qualitative characters such as new and unique shapes and colors of the morphology must be enhanced further to increase its economic and aesthetic significance as a floriculture commodity. The induced mutation technique has been proven to improve plants' morphological diversity, and even numerous novel cultivars are produced from artificial mutations. The recurrent irradiation technique was applied in the P. grandiflora mutation breeding program and produced new morphological variations of P. grandiflora until the MV7 generation (seventh generation of the mutation breeding program). The current study aimed to evaluate the diversity of morphological characters of P. grandiflora mutants in the MV8 population resulted from reccurent irradiation technique. Fifty-three selected mutants of P. grandiflora generation MV7 were multiplied by stem cuttings to create an MV8 population. The total MV8 population of P. grandiflora, the result of vegetative propagation, was 1104 plants. The diversity of morphological characters of P. grandiflora in the MV8 population was identified quantitatively (measurement) and qualitatively (visual observation). The results of this study reveal that several P. grandiflora mutants in the MV8 population have a new phenotypic appearance, chiefly in the qualitative characters of flowers. Besides, most of the P. grandiflora MV8 mutant population has inherited identical morphological characters from the previous generation (MV7 population). Further morphological analysis in the next generation needs to be conducted to evaluate the morphological stability of P. grandiflora mutants to develop new cultivars and to investigate the possibility of new phenotypic variations caused by recurrent irradiation treatments.

Abstract. Aisyah SI, Oktavia AWP, Ayuningtyas AA, Putra RP, Prassiska S, Jamilah S, Nurcholis W. 2023. Short Communication: Differences in phytochemical compounds and antioxidant activity of Portulaca oleracea and Portulaca grandiflora. Biodiversitas 24: 1385-1390. Portulaca oleracea and Portulaca grandiflora are medicinal ornamental plants used in traditional and modern medicine. Therefore, this study aimed to analyze the phytochemical compounds and antioxidant activity in two purslane plants, P. oleracea,and P. grandiflora. The purslane ethanol extract was obtained by sonication and maceration methods. The phytochemical screening included the examination of secondary plant metabolites, while antioxidant activity was analyzed using the 2,2-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) and cupric ion reducing antioxidant capacity (CUPRAC) methods. The results showed that both extract samples contain alkaloids, phenol hydroquinones, flavonoids, saponins, tannins, triterpenoids, and steroids. The highest ABTS antioxidant activity was found in P. grandiflora extract at 26.93 µmol TE/g FW compared to P. oleracea extract at 15.98 µmol TE/g FW. The highest CUPRAC antioxidant activity was found in the P. oleracea extract at 33.22 µmol TE/g FW, while in the P. grandiflora extract, it was 18.55 µmol TE/g FW. Based on the results, it was concluded that the chemical complexity of various purslane plants causes differences in the antioxidant capacity.
