Abstract

The purpose of this study was to characterize the active compounds in Indonesian local rice that are resistant to environmental stress in order to identify the nature of resistance to environmental stress, one of the indicators of which is the presence of flavonoid compounds. This step is one of the efforts that will lead to the acquisition of gene donors in the assembly of varieties resistant to biotic stress (pests and diseases) and abiotic stress (drought, high salinity, low temperature), which are very necessary in rice breeding programs. The method used is to plant 8 local rice varieties that are resistant to environmental stress in buckets in greenhouses. Next, analyze the content of active compounds by extracting the leaves and stems of rice plants, then macerate with methanol for 48 hours and test the content of active compounds. Then the total flavonoid content test was carried out using a quercetin standard and measured using a spectrophotometer. Whatever the results of this study, all samples showed active compounds containing flavonoids, alkaloids, tannins and saponins which were indicated by indicators of color change when tested with certain reagents. The results of the Flavonoid content analysis showed that the pendok variety had the highest flavonoid content, namely 3.9253 ± 0.06, and the Sigupai variety had the lowest flavonoid content, with a value of 1.8073 ± 0.07.

Abstract

One of the most common stresses in rice cultivation is salinity. Rice plants stressed by salinity exhibit changes such as yellowing leaves, drying tips, and chlorosis. The efforts made by the government and farmers so far include implementing cultivation scheduling techniques, planting patterns, and using stress-resistant varieties, as well as improving soil to increase water-holding capacity through lime application. Each of these efforts comes with its own risks. Another approach to enhance the growth and yield of rice plants is the application of vitamins. Providing vitamins can stimulate the growth of plant organs, as they play a crucial role in the growth process by acting as catalysts for metabolism. Research has indicated that vitamin B1 can significantly promote plant growth under stressful conditions. This study aims to investigate the positive effects of various concentrations of vitamin B1 on the growth and yield of rice plants while also reducing salinity stress. The method used involved planting three varieties of rice—IR-46, Inpari-32, and Pokkali—in planting buckets using the TABELA system. Vitamin B1 was applied at concentrations of 0, 5, and 10 mM during the peak vegetative phase, with salinity stress of 6 dS/m introduced one day after vitamin application. The plants were maintained under salinity stress conditions until harvest, during which morphological and phytochemical analyses were conducted. Morphological analysis included measurements of plant height, number of tillers, number of productive tillers, number of grains per panicle, and percentage of healthy grains. Biochemical parameters measured included total chlorophyll and electrolyte leakage analysis. The results indicate that vitamin B1 can effectively reduce stress in plants affected by salinity.
