Abstract

AbstrakMorfologi serbuk sari dapat dipakai untuk identifikasi tumbuhan, sumber bukti taksonomi, dan diterapkan dalam banyak disiplin ilmu. Penelitian ini bertujuan untuk menggambarkan ciri morfologi serbuk sari yang berasal dari tumbuhan legum. Sampel serbuk sari diperoleh dari bunga yang dikoleksi di area kampus. Koleksi bunga dilakukan dengan metode jelajah di kawasan kampus IPB, Dramaga. Sampel serbuk sari yang akan diamati dibuat dengan metode asetolisis. Pengukuran morfologi polen dihitung berdasarkan sumbu polar dan ekuatorial dalam skala mikrometer. Ciri morfologi serbuk sari yang diteliti meliputi bentuk, unit serbuk sari, tipe aperture, ukuran, indeks P/E, dan ornamentasi eksin. Serbuk sari diamati dengan mikroskop majemuk Olympus (CX-33) yang dilengkapi kamera indomikro. Hasil penelitian menunjukkan bahwa bentuk serbuk sari pada legum ada dua macam yaitu circular dan circular oval. Ukuran serbuk sari beragam dari sangat kecil sampai sangat besar. Serbuk sari memiliki indeks P/E > 1,00. Tipe aperture meliputi monoporate, triporate, tetraporate, tricolpate, dan tricolporate. Ornamentasi eksin yang dijumpai berupa scabrate, reticulate, dan psilate. Serbuk sari yang diamati pada penelitian ini menggambarkan morfologi yang khas sehingga dapat dijadikan karakter tambahan dalam mengidentifikasi tumbuhan legum.AbstractPollen morphology can be usefull for plant identification, sources of taxonomic evidence, and apply in many disciplines. This study aimed to describe the morphological characteristics of pollen from legume plants. Pollen samples were obtained from flowers collected in the campus area. The collection of flowers was carried out using the roaming method in the area of the IPB campus, Dramaga. The pollen sample to be observed was made by the acetolysis method. Pollen morphology measurements were calculated based on the polar and equatorial axes on the micrometer scale. The morphological characteristics of the pollen studied included pollen shape, pollen unit, aperture type, size, P/E index, and exine ornamentation. Pollen grains were observed with an Olympus compound microscope (CX-33) equipped with an indomicro camera. The results showed that there are two forms of pollen grains, namely circular and circular oval. Pollen sizes vary from very small to very large. Pollen has a P/E index > 1.00. The aperture types include monoporate, triporate, tetraporate, tricolpate, and tricolporate. The exine ornamentation found is scabrate, reticulate, and psilate. The pollen observed in this study shows a distinctive morphology so that it can be used as an additional character in identifying legume plant.

Abstract

Information on flower-visiting insects, especially pollinators of the pulasan plant (Nephelium ramboutan-ake), a species that tends to cross-pollinate, is essential for increasing fruit production. Unfortunately, there is minimal information on flower-visiting insects associated with pulasan. This research aimed to study the diversity and abundance of visiting insects on pulasan in the Mekarsari Fruit Garden, Bogor. Observations of insects were conducted using the fixed sample method, with samples taken every 20 minutes through direct observation from 06:00 am to 02:00 pm during the flowering period. Results showed that 24 insect species, belonging to 24 genera across six orders, visited the pulasan, with the order Diptera being the most dominant among the visiting insects. The potential insect species as pollinators of pulasan were Lathyrophthalmus sp. and Amata huebneri. Knowledge about flower-visiting insects plays an important role in the conservation of insects—especially pollinators—as well as the pulasan plant, a local species.

Abstract

Indonesia, as the world's largest nickel producer, has vast ultramafic areas that have the potential to become habitats for nickel hyperaccumulator plants (Ni). This study aimed to explore and analyze nickel hyperaccumulator plants in the mining area of CV. Unaaha Bakti Persada, North Konawe Regency, Southeast Sulawesi, Indonesia. The research was conducted from June to November 2023 using the exploration method at three observation stations, each consisting of three plots. The research stages carried out include exploration, plant collection and identification, and analysis of Ni content in soil as well as plant tissue using Atomic Absorption Spectrophotometry (AAS). A total of 32 plant species were found, which was dominated by Pteridium aquilinum ferns at Stations I and III and Scleria lithosperma grasses at Station II. The Ni content of the soil was very high (5,458.32–5,938.41 mg/kg) and far above the normal threshold. Several species showed high Ni accumulation capacity, with the most of six were Sarcotheca celebica, Knema metanensis, Pluchea carolinensis, Gymnostoma sumatrana, and Justicia gendarussa. The post mining sites were categorized as marginal due to heavy metal toxicity (Ni, Co, Cr), and therefore, only tolerant plants can survive. Sarcotheca celebica had the highest BCF value (0.1421) and was classified as a moderate accumulator. All the six species has the potential to be used for phytoremediation, phytomining and reclamation of post mining areas in Southeast Sulawesi.
