Abstract

Musa paradisiaca cv Haji is a local banana of Lombok that has a longer shelf life. The determination of the haji banana genome still uses a scoring method based on morphological character. Clarification of ploidy levels and genome types can be done using chromosome analysis. The initial information needed to perform the karyotype analysis is identifying the cleavage time of M. paradisiaca cv Haji. Banana Haji on the island of Lombok has a different local name, so morphological identification of the haji banana accession is required. Morphological observations were conducted on three accessions of Haji bananas from different cultivation sites. Identification of the time of mitosis cleavage is made by the Squash method. The results showed a uniform synapomorphic character in the haji banana accession. The characters include the aspects of pseudostem (normal), shiny pseudostem, imbricate young bractea (young bractea slightly stacked), red inner bractea, straight ovary, and no pigmentation on the stylus. The autapomorphic character of Haji banana accession in this study included inside the pseudostem of the red-green, the position of horizontal fruit bunches, a fair amount of wax on the surface of the lower leaf, and the petiole of the lower leaf in pink. There are morphological character differences in Haji cultivar accession on pseudostem color and tepal color pigmentation. The time of mitosis division in Haji bananas, especially the prophase stage - metaphase from 06.38 - 07.38 Wita. The results obtained in this study can be used as a foundation to conduct karyotype analysis of Musa paradisisaca cv Haji.

Abstract

The increasing sea surface temperature could be approved CO2 levels on the coast. It has been assumed the primary productivity in the intertidal zone was to absorb CO2 from the water column for photosynthesis. In addition, the substrate floor has a potential source of CO2 from decomposers. Phytoplankton and seagrasses are the primary productivity in the intertidal zone. Both of them have chlorophyll, they maintain the CO2 as a carbon source to move the photosynthetic systems to develop the metabolism of the body's cells. The measurements were made of the leaves and rhizomes of all the seagrass species. The absorption process was clarified by measuring the growth rate, percent LOI, and percent carbon in the whole body of the Tetraselmis sp and Dunaliella sp, which were phytoplankton species isolated from seagrass ecosystems. Enhalus acoroides (Ea) had the highest carbon content.  On the other hand, Halophila ovalis and Halophila minor are the lowest carbon due to the distribution of Ea being the widest, they were found in all of the sampling areas. In addition, the factor that was supported was due to its high growth rate ability. Phytoplankton and seagrass on the coast of Sekotong Barat absorb CO2 in the water column and floor of the sediment (carbon sink). The presence of a different increase in carbon content between Tetrasemis sp and Dunaliella sp indicates, the species of phytoplankton respond differently to CO2 stress in the ocean.
