Abstract

Coastal areas are potential land for the cultivation of feed crops to support the availability of livestock forage. Indigofera zollingerianaplants have a high tolerance to salinity stress. Gamma irradiation technology, which can change the genetic structure of plants, is expected to increase plant tolerance. This study was conducted to determine the morphological response of Indigofera zollingeriana Mutant, two plants irradiated with gamma rays in coastal areas. This study used a complete randomized design (CRD) method with ten treatments and six replications. The treatments consisted of P0 (control/without irradiation); P1 (Indigofera M2 50 Gy); P2 (Indigofera M2 100 Gy); P3 (Indigofera M2 150 Gy); P4 (Indigofera M2 200 Gy); P5 (without irradiation + salinity stress); P6 (Indigofera M2 50 Gy + salinity stress); P7 (Indigofera M2 100 Gy + salinity stress); P8 (Indigofera M2 150 Gy + salinity stress); and P9 (Indigofera M2 200 Gy + salinity stress). The analysis of variance showed that different doses of gamma irradiation and salinity stress had a significant effect (P<0.05) on stem diameter and number of flowers of Indigofera zollingeriana plants. Irradiation dose of 150 Gy with salinity stress during seedling can grow higher leaves when planted in coastal areas. Keywords: Salinity Stress, Indigofera zollingeriana, Gamma Irradiation

Abstract

Coastal areas have great potential to be developed. One of the good sectors developed in coastal areas is livestock, but the obstacle to the development of livestock in coastal areas is saline land conditions that can affect the process of plant growth. Indigofera zollingeriana is a plant that is tolerant to various types of environmental stress, one of which is salinity stress. Induced mutation is currently the most effective breeding method for plant genetic improvement. One example of induced mutation treatment is gamma irradiation. This study used a complete randomized design method with ten treatments and six replicates. The treatments consisted of P0 (Control/Without irradiation); P1 (50 Gy gamma irradiation); P2 (100 Gy gamma irradiation); P3 (150 Gy gamma irradiation); P4 (200 Gy gamma irradiation); P5 (Irradiation was given salinity stress); P6 (50 Gy gamma irradiation and salinity stress); P7 (100 Gy gamma irradiation and salinity stress); P8 (150 Gy gamma irradiation and salinity stress); and P9 (200 Gy gamma irradiation and salinity stress). The results of the analysis of variance showed that the treatment of gamma irradiation dose and salinity stress had a significant effect (P<0.05) on the total weight, leaf weight, and leaf production of Indigofera but no significant effect (P>0.05) on stem weight and production.
