Abstract

   Bogor Botanic Gardens is one of the outstanding green areas in Bogor City. Thousands of plant species are growing and providing suitable habitats and feed for various pollinators, such as butterflies, bees, and wasps. A well-designed pollination garden will benefit the pollinators and also create an educational facility for the community. This study aimed to select and characterize species of flowering plants that effectively attract pollinators, particularly Lepidoptera and Hymenoptera, in the pollination garden candidate area. The observa-tion had been carried out on 12 ornamental plant species: Pennisetum purpureum, Cosmos sp., Pachystachys lutea, Cuphea hyssopifolia, Orthosiphon aristatus, Lantana camara, Citrus aurantifolia, Buddleja davidii, Ixora javanica, Nerium oleander, Hibiscus rosa-sinensis, and Aglaia odorata. The method for observing pollinators was a standard walking method. Pollinator photos, its number, its visit time, and the plants it visited were recorded. A total of 23 species of Lepidoptera (20 species from 4 families and 3 species were unidentified) and 9 species of Hymenoptera (4 families) were found in the area with the best obser-vation time at 08.30-09.30 (GMT+7). The most visited plants by pollinators were Cuphea hyssopifolia, Lantana camara and Orthosiphon aristatus. Lepidoptera and Hymenoptera preferred blue-purple and bright-orange-yellow flowers. In addition, the flower characters that might influence pollinator visits are also described. The result would be an essential recommendation for plant selection, landscape design, and construction of the pollination garden in Bogor Botanic Gardens.

Abstract

The process of forest regeneration can take place within a certain period of time. Sprouting is a form of strategy for in adapting to its environment for success in regenerating. The Research on  the diversity and diameter growth rate of sprouting-type tree in Bukit Pinang-pinang forest permanent plots, West Sumatra was carried out from October 2012 to December 2016 in the forest of Bukit Pinang-Pinang, West Sumatra and Herbarium Department of Biology, Universitas Andalas, Padang. This research was conducted using a survey method by census. The parameters analyzed were plant species composition, Morishita Index, Mann-Whitney test, Regression and Correlation test as well as RDGR (Relative Diameter of Growth Rate). The result of experiment was found 40 species of trees sprouting type in forest permanent plot Bukit Pinang-Pinang. The pattern of sprouting type trees distribution in the study locations was found to have a clustered, random and uniform pattern. Relative Diameter Growth Rate (RDGR) of 40 sprouting types of trees in the Bukit Pinang-Pinang forest permanent plots ranged from 0.003 cm/cm/year to 0.0288 cm/cm/year. Altitude did not affect  RDGR of an individual tree sprouting type for 31 years

Abstract

AbstrakDioscorea bulbifera L. (Dioscoreaceae) merupakan salah satu tanaman invasif yang menciptakan masalah lingkungan. D bulbifera mengandung alelopati yang memengaruhi proses fisiologis pada spesies lain. Penelitian ini bertujuan untuk mengetahui pengaruh alelopati berbagai konsentrasi ekstrak daun dan umbi D. bulbifera L. terhadap perkecambahan biji Shorea selanica (Lam.) Blume. Metode yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan sepuluh perlakuan dan tiga ulangan. Perlakuan yang diberikan adalah perbedaan konsentrasi ekstrak D. bulbifera 25, 50, 75, 100%, dan kontrol. Berdasarkan hasil uji skrining fitokimia, semua metabolit sekunder dalam ekstrak daun menunjukkan hasil yang positif. Senyawa golongan saponin, tanin, flavonoid, dan steroid/terpenoid terdeteksi dengan kuat sedangkan senyawa alkaloid kurang kuat. Senyawa fenol tersebut adalah fenol, 1,2-benzenediol (dalam ekstrak daun) dan fenol, 1,2-benzendiol, 1,4-benzendiol, dan 2-metoksifenol (dalam ekstrak umbi). Berdasarkan uji perkecambahan, ekstrak metanol umbi dan daun D. bulbifera berpengaruh nyata terhadap daya kecambah, koefisien kecepatan berkecambah, dan koefisien keserempakan berkecambah S. selanica. Konsentrasi yang menurunkan viabilitas biji terendah adalah pada konsentrasi 75% dan 100% dengan rata-rata daya kecambah 10,00 ± 6,32 % (pada ektrak umbi) dan 0,00 ± 6,32 % (pada ektrak daun). AbstractDioscorea bulbifera L. (Dioscoreaceae) is one of the most unutilized invasive plants. This plant contains allelopathy that affects the physiological process of native species. This study aimed to discover the type of allelochemical in D. bulbifera and its effect on seed germination of Shorea selanica (Lam.) Blume. The method used was a Completely Randomized Design with ten treatments and three replications. The treatment given was the different concentration of D. bulbifera extract of 25, 50, 75, 100%, and control. Based on phytochemical screening tests, saponin, tannin, flavonoid, and steroid/terpenoid compounds were detected in leaf and tuber extract. The total phenolic in leaf extract was more significant than that in the tuber extract of D. bulbifera but the type of phenolic compounds was lower. The phenolic compounds were phenol, 1,2-benzenediol (in leaf extracts) and phenol, 1,2-benzendiol, 1,4-benzendiol, and 2-methoxyphenol (in tuber extracts). Based on the germination test, it was found that the methanol extract from the tubers and leaf of D. bulbifera significantly affected the germination capacity, coefficient rate of germination, and simultaneity coefficient of germination of S. selanica. It was found that treatment of concentration of 75% and 100% resulted in the lowest seed viability reduction with an average germination rate of 10.00 ± 6.32% (in tuber extracts) and 0.00 ± 6.32% (in leaf extracts).

Abstract

Bisbul (Diospyros discolor Willd.) is one of the collections from the Bogor Botanical (BBG). The wide distribution of this plant in Southeast Asia's tropical forests creates many morphometric variations of this species. The diversity of leaf morphometric variations of a plant species can be the basis for grouping various species. This study aimed to determine the morphometric diversity of Bisbul leaves from various locations of origin. The study took samples of bisbul leaves from Bogor Botanical Gardens from three accessions, namely the Philippines, West Java, and Papua. All the trees are over 30 years old. The leaves are taken based on a horizontal position, vertical crown, and leafage. The results showed that the origin of the location gave different multiplier values to calculate the area, namely the Philippines y = 0.733x + 0.034; West Java y = 0.765x-2,949; and Papua y = 0.758x-1.389. The length to leaf width ratio also has differences, namely, the Philippines, which is 2.64, West Java 2.65, and Papua 2.81. The chlorophyll content in young leaves increases in old leaves. The samples from Papua also have the highest chlorophyll content compared to the Philippines and West Java. This difference indicates morphometric variations between the three, even within one species. Some environmental conditions may affect shade areas and tree age. In addition, DNA research from accession D. discolor is also needed to determine the cause of the morphometric variation.

Abstract

Researchers about Diospyros have not extensively conducted studies on the morphological characteristics to enhance information for taxonomic hierarchy purposes. Diospyros in Indonesia has great potential for in-depth research due to its unique characteristics, particularly in Sulawesi. This research aims to fill the knowledge gap regarding investigating phenotypic variations in Diospyros, specifically in the Sulawesi region. Nine species of Diospyros from the BBG collection will be observed and described for their morphological characteristics. The results indicate 25 variations of 50 characters in morphological characteristics. Variations in morphological characters can suggest that each species adapts to the surrounding environmental conditions.

Abstract

The leaves of Dioscorea bulbifera L. have chemical compounds that have the potential as bioinsecticides. This study aims to determine the effectiveness of polar, semi-polar, and non-polar fractions in D. bulbifera leaf extract as bioinsecticides. The research design used was a Factorial, Completely Randomized Design consisting of two factors with five repetitions using the contact method against Cryptotermes cynocephalus. The first factor was the type of solvent: non-polar solvents, semi-polar solvents, and polar solvents. The second factor was concentration, with a range of 5%, 4%, 3%, 2%, and 1%. Based on the results, the D. bulbifera leaves in the polar fraction contain alkaloids, flavonoids, phenols, triterpenoids, and saponins. The semi-polar fraction contains alkaloids, phenols, and steroids. The non-polar fraction contains alkaloids, phenols, and triterpenoids. GC-MS identification showed 20 metabolite compounds as potential as botanical insecticides. The highest termite mortality was in the non-polar fraction, with a 4% concentration of 32.80% (equivalent to a corrected mortality of 27.58%). The semi-polar fraction (3.20 g and 15.10%) at a concentration of 5% (2.58 g and 12.19%), showed the best reduction in test weight and degree of damage. This result indicates that D. bulbifera is an effective bioinsecticide in the repellent group.
