“…Meanwhile, at doses of 15 Gy, 20 Gy, and 25 Gy, leaf length and area increased slightly but not significantly compared to the control. This finding is consistent with the research from Mounir et al (2022), who discovered that a low dose of gamma irradiation could increase the leaf area. The dose of 40 and 60 Gy used in this study was categorized as low irradiation doses, which could have a stimulatory effect in a positive direction (Majeed et al 2017), resulting in longer leaves and wider areas than the control.…”

Abstract. Cahyaningsih AP, Etikawati N, Yunus A. 2022. Morphological characters variation of Indonesian accession Echinacea purpurea in response to gamma-ray irradiation. Biodiversitas 23: 5351-5359. Indonesia was one of the countries that introduced E. purpurea as a medicinal plant. Accessions of E. purpurea that have been successfully cultivated in Indonesia have narrow genetic diversity, lack accession variation, and have almost uniform tillers. This study was conducted to determine the effect of different doses of gamma-ray irradiation on morphological characteristics of E. purpurea accession B2P2TOOT. The experimental design was a Randomized Block Design with three replications, and six doses of gamma-ray irradiation (0, 15 Gy, 20 Gy, 25 Gy, 40 Gy, and 60 Gy) were used. The qualitative morphological data were presented descriptively; quantitative data were analyzed using ANOVA followed by a DMRT test at a 5% level with SPSS 16.0 application. The Dice similarity algorithm analyzed the similarity index, group analysis, and dendrogram construction using the UPGMA method with the NTSYS 2.02 application. Gamma-ray irradiation treatment increased the survival rate of E. purpurea plants grown in tropical lowlands. A dose of 15-60 Gy gamma irradiation did not affect the qualitative morphology of E. purpurea roots, stems, and leaves. Irradiation at doses of 40 Gy and 60 Gy resulted in flowers with more variation in color, overall flower shape, and arrangement of ray floret. Gamma irradiation significantly affected plant height, leaf length, leaf area, flower angle, and the first day of flowering. The 40 and 60 Gy doses resulted in longer leaves with wider leaf surfaces. The dendrogram revealed that E. purpurea irradiation resulted in two main groups, with doses of 40 and 60 Gy forming their groups and increasing morphological variation by 30% compared to controls.

“…A dose of 5 Gy had a pronounced stimulating effect on plant growth, dry matter content, photosynthetic pigments, nitrogen, phosphorus, potassium, total carbohydrates, and inulin. Phenolic and flavonoid content correlated with the dose of ionizing radiation and reached a maximum at doses of 5–10 Gy [ 53 ].…”

As a result of the accident at the Chornobyl Nuclear Power Plant, significant territories were exposed to ionizing radiation. Some isotopes, such as 137Cs, are capable of making a significant impact on living organisms in the long-term perspective. The generation of reactive oxygen species is one mechanism by which ionizing radiation affects living organisms, initiating mechanisms of antioxidant protection. In this article, the effect of increased ionizing radiation on the content of non–enzymatic antioxidants and the activity of antioxidant defense enzymes of Helianthus tuberosum L. was studied. This plant is widely distributed in Europe and characterized by high adaptability to abiotic factors. We found that the activity of antioxidant defense enzymes, such as catalase and peroxidase, weakly correlated with radiation exposure. The activity of ascorbate peroxidase, on the contrary, is strongly positively correlated with radiation exposure. The samples growing on the territory with constant low exposure to ionizing radiation were also characterized by an increased concentration of ascorbic acid and water-soluble phenolic compounds compared to the controls. This study may be useful for understanding the mechanisms underlying the adaptive reactions of plants under prolonged exposure to ionizing radiation.

“…Penerapan dosis rendah sinar gamma untuk tanaman mendorong pertumbuhan sinyal dengan menambah kapasitas antioksidan sel atau dengan mengubah jalur sinyal hormon. Menurut Mounir et al, (2022), jaringan tanaman setelah terkena radiasi dosis rendah memperoleh kapasitas untuk memancarkan radiasi biogenik sekunder dan merangsang sel-sel yang tidak aktif untuk membelah mungkin dengan mengaktifkan berbagai reseptor membrane. Dosis sinar gamma yang ditingkatkan diperkirakan berbahaya bagi sel tanaman karena mutasi DNA pada tahap interfase siklus sel, yang mengganggu diferensiasi sel dan menghambat genesis tunas, sehingga respons pertumbuhan terhambat (Smillie et al, 2012).…”

“…Respon morfologi tanaman terhadap sinar gamma mudah terlihat dan untuk mengimbanginya, berbagai parameter biokimia termasuk kandungan klorofil, protein, asam amino, prolin, pati, dan tingkat ROS dapat diamati. Hal ini selalu terjadi dalam fisiologi dan biokimia tanaman yang selanjutnya mengakibatkan ketidakseimbangan hormonal, penghambatan enzim, dan gangguan pertukaran gas (Mounir et al, 2022). Song et al, (2012) menyatakan bahwa mutan padi yang telah diiradiasi dengan sinar gamma mengalami peningkatan antioksidan, asam amino dan klorofil.…”

“…Dampak sinar gamma pada tanaman stres abiotik Para peneliti dari waktu ke waktu melaporkan bahwa dosis rendah sinar gamma memperbaiki stres logam berat pada berbagai tanaman, tetapi penjelasan konklusif untuk efek stimulasinya belum ditarik secara empiris (Maghuly et al, 2017;Spencer-Lopes et al, 2018). Para ilmuwan berpendapat bahwa dosis rendah (5-100 Gy) dari iradiasi gamma telah memicu sintesis RNA dan protein pada tahap perkecambahan, serta pada tanaman stres Cd (Kumar et al, 2017;Mounir et al, 2022). Paparan logam berat menyebabkan peningkatan produksi ROS, yang menyebabkan pembengkakan pada tilakoid dan perubahan membran dalam kloroplas karena interaksi dengan kelompok enzim tiol (-SH) (Wang et al, 2017) Modulasi respon fisiologis dan tingkat ekspresi gen yang terkait dengan ketahanan cekaman Pb telah diamati pada bibit Arabidopsis thaliana setelah diiradiasi dengan sinar gamma dosis rendah (50 Gy) (Qi et al, 2015).…”

The widespread use of mutagenesis for plant genetic improvement can be explained by a number of factors, including the fact that new varieties can be developed in a shorter time than conventional breeding methods and that transgenesis is more difficult to re-engineer. Gamma rays are physical mutagens that are often used in plant mutagenesis techniques and are safe for human health because there is no environmental risk in the induced generations. The method used in this paper is by grouping articles according to their relevance to the subject and year of research, and finally managing the explanatory structure. Journal articles for the period 2012 to 2022 were searched using keywords: breeding, mutation, mutagen, rice, and gamma iridation. The selection of selected articles comes from the PubMed, Elsevier, and Springer web sites. This paper integrates the available data on the effects of mutation breeding of plant varieties in different countries and addresses the potential of gamma irrigation as a flexible and practical approach that can be applied to rice crops and an appropriate selection method.
