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

Lauraceae is a group of tropical plants with a wide distribution. The abundance and species richness of the Lauraceae family includes the under to the upper canopy of the forest. The Lauraceae family can be utilized in various sectors, especially economically. Limiting characters as a significance in the Lauraceae classification was needed to provide additional information regarding taxon grouping. This research aimed to study epidermal characteristics, leaf venation variations, and the diversity of Lauraceae species under different forest environmental conditions. The research procedure involved: collecting ecological field data and morphological identification using a purposive sampling method based on the presence of species. Soil sampling and environmental microclimate were measured on each plot. The anatomical process was carried out by recording characters. Correlation between environmental factors and plant targets used canonical correspondence analysis. The kinship between members of Lauraceae was expressed in a dendrogram. The result of this study showed that Lauraceae could live at various elevations. The analysis data indicated differences in environmental factors that affect the existence of Lauraceae species. Leaf venation studies support clustering in the family using characters such as primary, secondary, tertiary veins, and areola. Observation of leaf venation can be used as a taxonomic significance in the family Lauraceae. Epidermal cell walls in leaf samples are straight, curved shallow, deep, and sharp. Other characters that can be found are anomocytic, laterocytic, and brachyparasitic types of stomata, with stellate and glandless trichomes The anatomical dendrogram separated Lauraceae into clusters on a similarity coefficient scale.

Abstract

PRASAJA, D., CHIKMAWATI, T., SULISTIJORINI, S., PURWANTO, Y. & DJUITA, N. R. 2025. The ethnoecology of the Malay community to support the management of functional food source areas in Belitung Regency, Indone-sia. Reinwardtia 24(2): 199‒217. — The Malay community in Belitung Regency is rich in local knowledge about the management of the Belitung community landscape, which has been passed down from generation to generation. This local knowledge enables food production from its sources, but there is no information on the diversity and composi-tion of plants in the Belitung community's landscapes. This study aimed to analyze the diversity, composition, and conservation strategies of food plants in the Belitung community landscape. The study was conducted using the vege-tation analysis method, which created tiered square plots of various sizes. Plant conservation status is determined based on the ICS and the Important Value Index (IVI). The most common family found in all landscapes (rimba, bebak, kerangas bebak, kelekak, garden, homegarden) is Myrtaceae (21 species), except in rice fields, it is Poaceae, and in ume is Euphorbiaceae. Food plants are most found in homegarden landscapes (136 species included in 57 fami-lies). The cultivation and development of other potentials process must be carried out for plants with low/moderate IVI and high ICS, such as Ananas comosus, Arenga pinnata, and Cocos nucifera. Information from this research can sup-port efforts to diversify and provide food availability to realize food security based on local wisdom and local knowledge regarding the species diversity and the potential of local food plants in the Belitung Malay community. Traditional landscapes have an important role in providing sustainable food sources, as well as being a strong local identity, and providing economic contributions to the Belitung Malay community.
