Cendana merupakan spesies asli Indonesia bagian timur, yang menjadi ras lahan di Gunung Sewu. Sembilan ras lahan di Gunung Sewu, seluruhnya tersusun atas tiga varian yang berbeda struktur dan warna bunganya (MK, merah kecil; MB, merah besar; dan KB, kuning besar). Penelitian ini bertujuan untuk menganalisis karakter pembungaan ketiga varian cendana di Gunung Sewu pada periode pembungaan tahun 2015; di tiga ras lahan yang mewakili tiap zona yaitu Nglanggeran (Zona Utara), Bleberan (Zona Tengah), dan Petir (Zona Selatan). Observasi meliputi fenologi, kemasakan organ reproduksi, display, dan struktur pembungaan. Struktur pembungaan dan longevity organ reproduksi berbeda antar varian. MB dan KB didominasi warna merah dan marun, perigonium lebih besar, organ reproduksi lebih panjang, posisi putik sejajar/lebih rendah dari benang sari, dan longevity lebih singkat. MK didominasi kuning hingga oranye, lebih kecil, posisi putik sejajar/lebih tinggi, dan longevity lebih lama. Display pembungaan berbeda antar ras lahan, namun tidak berbeda antar varian. Petir, dengan ukuran populasi terbesar, memproduksi paling banyak pohon berbunga dan total bunga untuk seluruh varian. Ras lahan dan varian berbunga dua kali setahun, namun dengan inisiasi dan durasi yang berbeda. KB berbunga lebih awal di seluruh ras lahan, sedangkan MB paling akhir. MK memiliki durasi pembungaan terpanjang. Perbedaan antar ras lahan lebih dipengaruhi oleh faktor lingkungan seperti ketinggian, jenis tanah, dan iklim. Ras lahan yang lebih rendah, kering, dan panas berbunga lebih awal dan singkat. Peningkatan temperatur dan turunnya status air tanah menyebabkan keguguran massal yang diikuti sequential replacement, mengakibatkan perubahan frekuensi pembungaan. Strategi konservasi cendana di Gunung Sewu perlu dirancang berbasis keragaman genetik, sinkroni pembungaan, dan kompatibilitas antar varian, dengan tetap mempertimbangkan keberagaman tempat tumbuhnya.Kata kunci: cendana; Gunung Sewu; pembungaan; ras lahan; varian bunga The Flowering Characters Variation Among Floral Variants and Landraces Along Geographical Gradients in Gunung SewuAbstractSandalwood was origin to the south-eastern islands of Indonesia, but is recently occured as new land-races in Gunung Sewu, Java island. All of land-races consisted of three floral variants (MK, refers to “merah kecil”; MB, “merah besar”; and KB, “kuning besar”, respectively). This research aimed to determine flowering of these variants among three of land-races which were representing geographical zone in Gunung Sewu: Nglanggeran, Blebera, and Petir. Observation on phenology, sexual organs maturity, floral structure, and display was conducted in 2015. Floral structures varied among variants. MB and KB dominated by red and maroon colors, possessed bigger perigonium, longer sexual organs but with shorter longevity, and similar/lower position of stylus to stamens. MK dominated by yellow to orange colors, smaller, similar/higher position of stylus, and longer longevity. Floral display varied among land-races but were similar among variants. Petir, with biggest population size, produced the most abundant flowers and flowering trees at all variants. Sandalwood flowered twice a year in all of land-races and variants, however, the onset and duration varied. KB flowered earliest while MB was the latest. MK possessed longest flowering period. Flowering varied among land-races due to the altitude, soils, and climatic differences. Lower altitude, drier, and warmer sites flowered earlier and shorter. Mass abortion and sequential replacement, resulting in the alteration on flowering frequency, occured due to the extreme temperature increment. Conservation strategy should be arranged based on genetic differentiation, flowering differences, and crossing abilities among variants. Differences of landscapes, which may contribute to the differences of environmental conditions and flowering processes, should also be considered.

Pertumbuhan tanaman dipengaruhi oleh faktor genetik dan faktor lingkungan. Salah satu faktor lingkungan yang sangat memengaruhi pertumbuhan adalah sifat kimia dan fisika tanah. Beberapa famili jati yang ditanam pada lokasi yang berbeda diduga mempunyai respon pertumbuhan yang berbeda pula. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan (tinggi dan diameter) tanaman jati dari 30 famili yang ditanam pada dua lokasi yang berbeda, secara khusus untuk mengetahui pengaruh karakteristik sifat kimia dan fisika tanah pada pertumbuhan jati di dua lokasi tersebut. Metode penelitian yang dilakukan untuk mengukur pertumbuhan 30 famili jati yaitu tinggi total tanaman dan diameter setinggi dada. Sampel tanah diambil dengan terlebih dahulu membuat lubang profil tanah berukuran 1 m × 1 m dengan kedalaman 1 meter kemudian sampel diambil dari kedalaman 0-10 cm, 10-20 cm, 20-40 cm, dan 40-60 cm. Sifat kimia yang diamati adalah pH H2O, C Organik, N total, P, K, Ca, dan Mg tersedia serta Kapasitas Pertukaran Kation (KPK), sedangkan sifat fisik yang diukur adalah tekstur. Analisis statistik dilakukan dengan melakukan uji-t. Hasil penelitian menunjukkan parameter diameter tanaman, semua (30) famili tanaman jati menunjukkan perbedaan yang nyata di antara dua lokasi, sedangkan parameter tinggi hanya sebagian kecil famili yang berbeda nyata. Karakter kimia dan fisik tanah juga menunjukkan perbedaan nyata di antara dua lokasi. Parameter kimia tanah yaitu pH H2O, K, Ca, dan Mg tersedia, berbeda nyata antara 2 lokasi sedangkan kandungan C Organik, P tersedia dan KPK tidak berbeda nyata. Sementara dari sifat fisiknya, kandungan lempung dan debu pada dua lokasi berbeda nyata, sedangkan kandungan pasirnya tidak berbeda secara nyata. Perbedaan-perbedaan tersebut menunjukkan beberapa sifat tanah memang memengaruhi respon tanaman jati dalam hal pertumbuhan baik tinggi maupun diameternya. The Effect of Soil Chemical and Physical Characteristics on Growth of 30 Families of Teak (Tectona grandis) in a 10-year-old Progeny TestAbstractSome environmental factors that greatly affect plant growth are soil’s physical and chemical properties. Some teak families planted at different locations alleged to have different growth responses. This study aimed to investigate the growth response of teak (height and diameter) from 30 families, and to determine the effect of soil chemical and physical characteristics on teak growth in two different locations. Teaks were measured for total height and diameter at breast height. Soil pits (size: 1 m x 1 m and 1 m in depth) were dug and samples were taken from 0-10 cm, 10-20 cm, 20-40 cm and 40-60 cm in depth. Soil characteristics measurement were conducted on pH (H2O), organic carbon, total Nitrogen, available P, K, Ca, and Mg, also the Cation Exchange Capacity (CEC). Further, soil physical properties been measured was soil texture. Statistical analysis was performed by t- test. The results showed that teak’s diameter of all 30 families, showed significant differences between the two locations, while only a small proportion of height parameters significantly differed among families. Chemical and physical characters of the soil also showed differences between the two locations. Soil pH (H2O), available K, Ca, and Mg, were significantly differed between the two locations while the content of organic C, available P and the CEC were not significantly differed. For the soil physical properties, content of clay and silt in two location significantly differed whereas the sand content did not differ significantly. These differences indicate that some properties of the soil were affecting the growth response of teak famili in terms of both height and diameter.

Acacia crassicarpa is widely grown in forest plantations with Acacia mangium and Eucalyptus spp. Ceratocystis sp. is identified as a significant pathogen, causing substantial damage to A. mangium plantations as well as infecting A. crassicarpa, Eucalyptus spp., and several fruit trees such as Lansium spp., which led to yield losses. Research reported that isolates of Ceratocystis derived from various hosts have varying pathogenicity. Therefore, this research aimed to characterize the morphological properties and evaluate pathogenicity levels of eight Ceratocystis isolates (AC1, AC2, AM1, AM2, AM3, AM4, EP1, and LA1) on A. crassicarpa seedlings. The investigation occurred in the shade house and at the Faculty of Forestry UGM, Forest Health and Protection Laboratory in Yogyakarta. Four-month-old A. crassicarpa seedlings were artificially inoculated with Ceratocystis isolates from A. mangium, A. crassicarpa, Eucalyptus spp., and Lansium spp. hosts. The experiment employed a completely randomized design with four replicates. The results showed that characteristics of the isolates varied, but the differences in perithecium size were statistically insignificant. EP1 had a lighter color (greyish olive) than the other isolates. It was the most virulent and had a high potential for use in screening the resistance of A. crassicarpa clones against Ceratocystis sp. in the future.
