Abstract

Grasses are known as part of palm plantation ecology and has benefits as source of ruminant feed. Besides, it is believed to have ability as Carbon Storage. However, to what extent the grass can be capable as Carbon Storage and what are the species that can be best fitted as Carbon Storage are still questionable especially for those that are grown on plantation. Thus, investigation was carried out to identify tropical grasses grown under palm plantation coverage that can be functioned as Carbon Storage as well as to determine its nutrition contents. Due to having many traditional plantations, Pauh District of Sarolangon Jambi was opted as observation area. From there, samples were taken randomly from plots and sub-plots that were pre-created. Grass samples are grouped into three groups; leave, stem and root, and taken to laboratory for analysis. Among those that were observed, Panicum brevifolium, Axonopus compressus, Centotheca longilamina, Centotheca longilamina ohwi and Schleria sumatrensis were shown their capability as carbon storage. However, those are carbon storage capable have slightly different in carbon and nitrogen contents, Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) analysis and almost the same in fiber fractions.

Abstract

Alfalfa is a leguminous protein source with high nutritional value and economic value. Abiotic stress inhibits growth and reduces alfalfa production in many aquaculture systems. New varieties were developed by gamma-ray mutation induction. The selection was carried out to obtain superior abiotic stress-tolerant plants. This study aims to evaluate and select alfalfa mutants under abiotic stress conditions. The design used in this study was a comple- tely randomized design (CRD) with a factorial pattern. The first factor is the type of acid-tolerant mutants, namely A44, A54, A35, and A45. The second factor is the PEG level which is 10%, 15%, and 20%. The variables observed included viability, plant height, number of leaves, leaf wilting, leaf color, media shrinkage, and wet weight. Alfalfa mutants resulting from acid-tolerant gamma irradiation were evaluated under dry stress conditions. The results showed that mutation induction resulted in various responses to growth. Gamma-ray irradiation produces plants that are tolerant to abiotic stress conditions. From the selection results obtained superior mutant candidates that are tolerant of acid stress and dry conditions. The A44 mutant had better tolerance to dry stress than others and became an acid- and dry-tolerant alfalfa mutant.
