Abstract

HIGHLIGHTS- Biostimulant Potential of Enhalus acoroides- Positive Effects of E. acoroides on Maize Growth- Reduction in H2O2 (Oxidative Stress) by Enhalus acoroides extractABSTRACTDrought poses a significant challenge to crop productivity, with maize particularly vulnerable. Enhancing maize tolerance to drought stress is crucial, and one promising approach involves using biostimulants derived from natural sources. The seagrass Enhalus acoroides is a potential biostimulant due to its rich phytochemical composition, including phenols, tannins, flavonoids, and pigments such as chlorophyll, lutein, pheophytin, and beta-carotene. These compounds exhibit antioxidant activity, suggesting their potential role in enhancing plant resilience to drought stress. This study evaluated the effects of E. acoroides extract on maize growth under drought conditions during the seedling phase and analyzed biochemical changes in maize plants treated with the extract. The extract was prepared using 10% dried E. acoroides leaves with a chloroform-to-ethanol solvent ratio of 9:1 (v/v) and subsequently dissolved in distilled water for final concentrations of 0.05%, 0.1%, 0.15%, 0.2%, and 0.25%. The results demonstrated that E. acoroides extract enhanced plant height, increased shoot and root fresh and dry weights. Additionally, plants sprayed with E. acoroides extract exhibited higher total sugar and protein content in the shoots as compared to non-sprayed plants. Under 20% polyethylene glycol (PEG)-induced drought stress, control plants showed severe leaf wilting, whereas extract-treated plants only had mild wilting. The chlorophyll, reducing sugar, total N, and tocopherol contents were also higher in extract-treated plants under PEG stress than in untreated controls. These findings indicate the potential of E. acoroides extract as a biostimulant for improving drought tolerance in maize.

Abstract

Identification of genetic diversity using molecular markers is important for basic information for plant conservation. Banana is a fruit bearing plants that important for food sources in human life. This study aimed to determine the optimum conditions of  PCR-RAPD reaction and RAPD primers that suitable to amplify DNA fragmens. DNA isolation was done using modified of CTAB and chloroform isoamil alcohol. The samples used was young leaves of nine banana cultivar plants. Optimation was done using variety of DNA and MgCl2 concentration. Eight primers produced by Operon Primer Technology were tested. The DNA genomic concentration obtained was in the range of 23,3 ng/µl – 70 ng/µl. The optimum conditions of PCR-RAPD of banana plants that produce clear band were 50 ng/µl DNA template, 3 mM MgCl2 with the number of thermal cycles was 40 x. There were six RAPD primers that successfully amplified DNA : OPA 02, OPA 04, OPB 12, OPD 20, OPH 01, and OPH 03. The primer OPA-04 had the lowest resolving power value (4,4) , while  OPH 01 had the highest (11,3) resolving power.

Abstract

Frangipani plants (Plumeria spp.) is a member of the Apocynaceae family that can live in various soil conditions. The anatomical structure of frangipani leaves generally consists of epidermis, stomata, trichomes, mesophyll, and vascular bundles. Anatomical characteristics can be used as complementary data in addition to morphological characteristic data in grouping a species. This study aims to determine the anatomical characteristics of leaves from epidermal cells and stomata in seven taxa of frangipani plants located in Pemogan Village, South Denpasar District, Denpasar City, Bali. The study was conducted by observing epidermal cells and stomata in leaf samples taken from the fifth to sixth leaves from the shoot with three leaves each per plant. Observation of epidermal cells and stomata was carried out by the boiling method with 60% nitric acid (HNO3) solution. The results showed that the characteristics of epidermal cells and stomata varied in epidermal cell size, stomata size, and stomatal index. Plumeria spp. has a polygonal epidermis (quadrilateral - octagonal) with irregular edges. The stomata are of the parasitic type, characterized by two neighboring cells located parallel to the guard cells, and are found in abundance on the adaxial and abaxial parts of the leaves in the six cultivars observed, except in P. obtusa L Singapore, where stomata were only found on the abaxial part of the leaves.

Abstract

ABSTRACT Fingerprints are one of the biometric systems currently available besides retina, eye, face and other biometric systems. Fingerprints can be divided into several patterns, namely loop, whorl and arch patterns. The aim of this research is to determine variations in fingerprint patterns in the Bedugul area and fishermen in the Perancak area, Bali Province. The sampling method used was the Purposive Sampling method by taking fingerprint samples from farmers in the Bedugul area and fishermen in the Perancak area. The variables observed were the fingerprint pattern and the number of finger tendrils on the proband's hand. The data obtained will be analyzed by calculating the Furuhata Index, Dankmeijer Index and Total Ridge Count. The results showed that fingerprint patterns, the Furuhata Index and the Dankmeijer Index were not different between male fishermen and female fishermen in Jembrana. Likewise, women farmers in Bedugul have fingerprint types that are no different from men. There are differences in the fingerprint patterns of the fishermen population in Jembrana and farmer in Bedugul. There is no difference in total ridge between fishermen in Jembrana and farmers in Bedugul.
