Abstract

Semarang apple (Syzygium samarangense) consists of many cultivars with different sugar contents. In each fruit, the sugar content is not evenly distributed. Fruit sweetness often determines the economic value of the semarang apple. The objectives of this study were 1) to find out the distribution of sugar amongst several semarang apple cultivars, 2) to know the distribution of sugar content in the fruits, 3) to find out the correlation between average rainy days per month versus sugar contents. The method used in this study was survey with purposive sampling, laboratory observation by measuring sugar content with a refractometer, and correlating sugar content versus rainy days per month. The results of this study showed that the fruit with the highest sugar content are the cultivar of Syzygium samarangense ‘Sukaluyu’ (max 16.5 ◦Brix), S. samarangense 'Madu’ (max 14 ◦Brix), S. samarangense 'Kesuma Merah’ (max 10.5 ◦Brix), S. samarangense 'Citra’ (max 8.5◦Brix) which are suitable for fresh fruits. While those with low sugar content such as S. samarangense 'Bajang Leang’ (4.5 ◦Brix), S. samarangense 'Kuning’ (4 ◦Brix) are more suitable for salad. In the fruits, highest sugar is normally accumulated at the fruit apex, and the lowest sugar is at the fruit base. Sugar levels are negatively correlated with the average rainy days per month. The fewer rainy days, the sweeter the fruit.

Abstract

Nepenthes merupakan tumbuhan karnivora yang dapat melakukan penyerbukan silang pada spesies yang sama maupun berbeda sehingga dapat menghasilkan Nepenthes hibrid. Analisis mengenai hubungan kekerabatan antara spesies Nepenthes dan hibridnya dapat dilakukan dengan pengamatan terhadap karakter morfologi. Tujuan penelitian ini yaitu untuk mengetahui karakter morfologi dan hubungan kekerabatan antara Nepenthes hibrid dan tetuanya. Penelitian ini menggunakan Nepenthes hibrid hasil persilangan antara N. mirabillis dan N. reinwardtiana yang ditemukan di Kecamatan Entikong Kabupaten Sanggau. Hubungan kekerabatan dianalisis menggunakan program NTSys dengan metode UPGMA. Nepenthes reinwardtiana tidak memiliki variasi warna dan bentuk pada kantongnya. Nepenthes mirabillis dan N. mirabillis X N. reinwardtiana memiliki variasi pada warna dan bentuk kantong. Nepenthes hibrid memiliki karakter yang diwarisi dari kedua tetuanya. Nepenthes reinwardtiana, N. mirabillis, dan N. mirabillis X N. reinwardtiana memiliki tingkat kemiripan 0,46 dan terbagi menjadi tiga klaster. Hubungan kekerabatan antara N. mirabillis dan N. mirabillis X N. reinwardtiana memiliki nilai koefisien kemiripan terbesar 0,77, sedangkan N. reinwardtiana dan N. mirabillis X N. reinwardtiana memiliki nilai koefisien kemiripan 0,64. Karakter morfologi menunjukkan perbedaan yang jelas pada kantong. Hubungan kekerabatan Nepenthes hibrid lebih dekat dengan N. mirabillis.

Abstract

The typification of two species of Marasmiellus is discussed. Since the holotypes of Marasmiellus nugatorius and Marasmiellus pangerangensis did not exist, therefore neotypes of both species are designated here. To aid further identification of those species, a line drawing of macro-micromorphological features is provided.

Abstract

Nothaphoebe Blume merupakan salah satu marga dari suku Lauraceae atau suku Medang-medangan, dan berada di dalam subgrup Persea bersama-sama dengan marga Alseodaphne, Dehaasia, Persea, Phoebe. Informasi mengenai keanekaragaman Nothaphoebe di Sumatera, khususnya di Provinsi Lampung belum pernah dilaporkan. Tujuan dari penelitian ini yaitu mengetahui karakter morfologi dan jenis-jenis dari marga Nothaphoebe yang berasal dari Lampung. Karakter morfologi yang diamati meliputi ranting, bentuk daun, bunga, dan buah. Hasil karakterisasi morfologi menunjukkan bahwa terdapat lima jenis Nothaphoebe dari provinsi Lampung, yaitu Nothaphoebe falcata, Nothaphoebe foetida, Nothaphoebe macrocarpa, Nothaphoebe magnifica, dan Nothaphoebe umbelliflora. Kunci identifikasi jenis, deskripsi masing-masing jenis dan peta distribusi disajikan dalam artikel ini.

Abstract

Tujuan penelitian ini adalah untuk mengetahui hubungan kekerabatan fenetik jenis-jenis tumbuhan genus Euphorbia (Euphorbiaceae) berdasarkan ciri morfologi di Desa Oben, Kecamatan Nekamese, Kabupaten Kupang, Nusa Tenggara Timur. Penelitian ini menggunakan metode deskriptif kualitatif dan kuantitatif dengan teknik pengambilan sampel secara eksplorasi, koleksi dan dokumentasi. Identifikasi dilakukan dengan mencocokkan ciri-ciri morfologi, serta gambar tumbuhan pada pustaka. Analisis hubungan kekerabatan jenis-jenis genus Euphorbia menggunakan prosedur simqual melalui program NTSYS–pc 2.02 (Numerical Taxonomy and Multivariate Analysis System). Analisis pengelompokan cluster menggunakan SHAN (Sequential Aglomerative Hierarchical and Nested Clustering). Kategori pengelompokan setiap STO menggunakan kriteria indeks similaritas (IS) dengan kriteria: IS: ≥ 0.75 = sangat dekat, 0.51–0.74 = dekat, 0.26–0.50 = tidak dekat, ≤ 0.25 = sangat tidak dekat. Hasil penelitian menunjukkan bahwa terdapat delapan jenis tumbuhan genus Euphorbia yaitu E. antiquorum L., E. heterophylla L., E. hirta L., E. milii Des Moul., E. pulcherrima Willd. & Klotzsch, E. tirucalli L., E. tithymaloides L., dan E. trigona Mill. Euphorbia milii memiliki 3 varian yaitu bunga merah, bunga kuning dan bunga merah jambu. Hubungan kekerabatan jenis-jenis tumbuhan genus Euphorbia berdasarkan fenogram dapat dikelompokan dalam 2 kelompok yaitu kelompok I dengan hubungan kekerabatan sangat dekat dan IS = 0.82 dimiliki oleh E. trigona dan E. antiquorum; kekerabatan dekat dengan IS = 0.71–0.53 dimiliki oleh E. milii, E. heterophylla, E. tithymaloides dan E. tirucalli. Kelompok II dengan hubungan kekerabatan sangat jauh atau sangat tidak dekat dengan IS = 0.49 dimiliki oleh E. hirta dan E. pulcherrima.

Abstract

Athyrium nigripes is a highly variable species described and recorded mostly from Java and few from surrounding islands. There are different arguments on its delimitation and hence its extent of distribution. We attempted to elucidate disagreement on delimitation of four related species described from Java: Athyrium nigripes, Aspidium costale, At. pulcherrimum and At. nitidulum with phenetic approach. The analysis formed four clusters; cluster I consist of the large sized and include type specimen of At. pulcherrimum and Asp. costale, cluster II for plants with standard form and include type specimen of At. nigripes, cluster III only for serrated plants and cluster IV contain the At. nitidulum form. Since Asp. costale clustered in group I, this species is more closely related to At. pulcherrimum than to At. nigripes nested in group II. Large size and degree of division indicate major clustering within the complex species.

Abstract

Wax apple is one of the superior fruits of Demak, especially cultivars 'Citra', 'Delima' and ‘Madu Deli Hijau'. Research on the wax apple of the three cultivars is still limited. Therefore, research on the authentication of wax apple cultivars based on morphological characters and metabolite profiles present in one location is important to do. The aims of this study were to identify morphological characters and analyze metabolite profiles, to analyze relationship and to identify morphological characters and metabolite marker profiles in the authentication activities of three wax apples cultivars. Sampling was in Boyolali Village, Demak Regency. The stages of this research included morphological characterization of stem, leaf, fruit and seed organs, phylogeny analysis with MVSP, metabolite profile analysis using GC-MS, and determination of morphological characters and metabolite profiles with PCA. The results showed that there were morphological diversity and metabolite profile variations of the three cultivars. Relationship analysis based on morphological characters and metabolite profiles resulted in different grouping patterns. 'Madu Deli Hijau' and 'Citra' are closely related based on morphological characters and a combination of morphological characters and metabolite profiles. Morphological characters in the authentication of the 'Citra' (dark red exocarp color), 'Delima' (bright red exocarp color, smooth and flat fruit surface, jagged fruit shape), in 'Madu Deli Hijau' (elongated leaf shape and exocarp is green with a pink tinge). Authentication of probable marker metabolite profiles on 'Citra', 'Delima' and 'Madu Deli Hijau' wax apples of 10, 7 and 5 compounds.
