Abstract Gamma-ray irradiation on Cempo Ireng can lead to the variation of morphological characteristics; hence, morphological characterization is necessary to determine changes in potential lines. This research aimed to characterize the potential lines as one of the requirements for proposing plant variety release and add black rice genetic diversity information. The research was carried out in the rice fields of Pakahan Village, Jogonalan, Klaten in January-June 2020 with the arrangement of potential lines 8,13 and 44 of M6 in a row. In total 30 plants were selected randomly for each potential line and observed 19 morphological characters. Data analysis was carried out descriptively and qualitatively with the Chi-Square test. The results showed that gamma-ray irradiation affects the characters of leaf angle, auricle color, ligule color, leaf-blade color, leaf surface, panicle type, grain color, apiculus color, and rice length. Potential line 8 had different characteristics compared to non-irradiated Cempo Ireng in the characters of auricle color, leaf-blade color, leaf width, panicle length, grain width, rice length, and rice width, while on potential lines 13 and 44 occur in the characters of the leaf surface and panicle length.

Abstract. Susila E, Susilowati A, Yunus A. 2019. The morphological diversity of Chrysanthemum resulted from gamma ray irradiation. Biodiversitas 20: 463-467. Chrysanthemum is a popular ornamental plant. The high market demand makes breeders develop new cultivars to meet market preferences. One way to get superior varieties of Chrysanthemum is by using gamma ray mutation induction which will increase the morphological variations. The purpose of this study is to determine the Chrysanthemum’s morphological diversity resulted from gamma irradiation through morphological markers. This experimental research used a completely randomized design (CRD) with one factor, i.e. radiation doses: 0 Gy (control), 10 Gy, 15 Gy, and 20 Gy. The observations were carried out qualitatively and quantitatively. The data obtained were analyzed using the SPSS 15.0 and the NTSYS (Numerical Taxonomy and Multivariate Analysis System) 2.02 program. The results showed that increasing the dose of gamma irradiation inhibited plant growth. Irradiation at 10 Gy and 20 Gy produced the most color changes in flowers compared to other doses. The basic color of 0 Gy irradiation is purple. Irradiation at 10 Gy and 20 Gy produced dark purple and deep red. Quantitative data showed that the treatment of gamma ray irradiation significantly affected the leaf length, leaf width, stem diameter, stem length, and diameter of flowers. The irradiation also caused changes in shape and texture of the leaves. The dendrogram showed that 20 Gy irradiation resulted the most diverse morphology compared to the control, 10 Gy and 15 Gy.

Abstract. Muhallilin I, Aisyah SI, Dewi Sukma D. 2019. The diversity of morphological characteristics and chemical content of Celosia cristata plantlets due to gamma ray irradiation. Biodiversitas 20: 862-866. Celosia cristata L. or better known as Jengger Ayam is an ornamental plant that has a unique flower shape with attractive colors. Besides, this plant also contains antioxidants and chemical compounds that are used for traditional medicine to treat high blood pressure, and diabetes or as eye ailments. Increased diversity of C. cristata through hybridization techniques is constrained by flowers forming small grains that makes it difficult for castration and isolation of reproductive organs. This study aimed to increase C. cristata diversity of morphology and chemical content using mutation techniques induced by gamma irradiation. Plantlets were irradiated at 0, 25, 50 and 75 Gy doses. Scoring was conducted for 5 weeks until MV6 generation. Planlets were acclimatized for 3 weeks. The surviving plants were moved onto experimental land until seeded and tested for phytochemicals. Gamma irradiation with 25, 50 and 75 Gy doses produced 4 clones that have morphological changes in color and shape of the stem, leaves, and flowers. Changes in chemical content were observed with the appearance of triterpenoid compounds in 1 clone irradiated with 25 Gy.

Passionflower is a member of Passifloraceae family, it can be used as medicinal and ornamental plants in addition to its consumption as fruit in the world. Guava (Psidium guajava L.) fruits, which has a rich nutrient content, are consumed both fresh and processed. Passionfruit and guava plants, which can only be cultivated in temperate southern coasts in our country, have gained commercial importance because of the fruits' export potential, high medical importance and nutrient. This study was carried out to determine the effects of some bioactivator applications on the criteria of sapling growth and development of passionflower and guava plants. The experiment was conducted between 2018-2019 under greenhouse conditions. Saplings obtained from seed germination in Akdeniz University Faculty of Agriculture Research and Experiment Area were used as plant material. 3 different commercial preparations called Messenger, Crop-set and ISR-2000 were used as bioactivators. Plant height (cm), stem diameter (mm) and number of leaves (number / plant) were measured weekly, in order to determine the effect of the applications on the growth and development of saplings. At the end of the study, it was determined that the highest average plant height (10.17 cm), stem diameter (13.53 mm) were obtained in ISR-2000 application. The highest average plant height (11.93 cm), stem diameter (16.44 mm) and number of leaves (9.07 units / plant) were obtained from Messenger application in guava plant. When the results obtained are evaluated, it is recommended that ISR-2000 bioactivator can be applied in passionflower sapling cultivation and Messenger bioactivator can be applied for guava sapling cultivation.
