The purpose of this study was to examine the morpho-physiological characteristics of leaves, fruits, and seeds of tembesu from five populations in South Sumatra and Western Java. Analysis of variance with completely randomized design was used to discern the characters among the five populations (Kemampo, Sungai Pinang, Kota Raya, Dago, and Carita). The results showed that all of the morpho-physiological characteristics of leaves, fruits, and seeds were significantly different among populations. Severalvariables of agro-climate significantly correlated with leaves, fruits, and seeds characteristics indicating the environment’s influence. Most of the charaters had higher environment coefficient of variances than genotypic coefficient of variances which revealed a high environment contributions. Based on the characteristics of leaves, fruits, and seeds, the populations can be grouped in two, i.e. the first group consisted of the population from South Sumatra (Kemampo, Sungai Pinang, Kota Raya) and the second group from the population of Western Java (Dago and Carita). The investigation has important practical implications for genetic resources management and future breedingprograms of tembesu. Key words: Fragraea fragrans, morphology, site grow, viability ABSTRAK Tembesu (Fagraea fragrans Roxb.) merupakan salah satu jenis multiguna asli Indonesia yang mampu  tumbuh pada berbagai tipe lahan, seperti lahan kering, lahan tergenang sementara dan selalu tergenang. Tujuan penelitian ini adalah untuk mengetahui keragaman karakteristik morfo fisiologi daun, buah, dan benih tembesu dari lima populasi di Sumatera Selatan dan Jawa Bagian Barat. Analisis ragam dengan menggunakan rancangan acak lengkap digunakan untuk mengidentifikasi perbedaan karakteristik daun, buah, dan benih tembesu dari lima populasi (Kemampo, Sungai Pinang, Kota Raya, Dago, dan Carita). Hasil penelitian menunjukkan seluruh karakter morfo-fisiologis daun, buah, dan benih tembesu berbeda nyata antar populasi. Beberapa variabel agro-iklim berkorelasi dengan karakteristik daun, buah, dan benih yang memberi indikasi adanya pengaruh lingkungan selain genetik. Sebagian besar karakteristik daun, buah, dan benih memiliki nilai koefisien keragaman lingkungan yang lebih besar dibandingkan koefisien keragaman genetik yang menunjukkan besarnya kontribusi lingkungan. Berdasarkan karakteristik daun, buah, dan benih, dari lima populasi yang diuji terdapat dua kelompok, yaitu kelompok pertama, populasi Sumatera Selatan  (Kemampo, Sungai Pinang, Kota Raya) dan kelompok kedua populasi Jawa Bagian Barat (Dago dan Carita). Penelitian mempunyai implikasi praktis yang penting untuk pengelolaan sumber daya genetik dan program pemuliaan tembesu ke depan.

Development of masoyi plants currently are constrained by meeting the needs for quality seeds in a large quantity on time. Therefore, vegetative propagation become one of the solutions for this problem. The aim of this study was to get the best media, cutting materials, and doses of growth regulators for vegetative propagation of masoyi. Completely randomized factorial design was used. The first factor was the media of cuttings (soil+sand (2:1, v/v), coconut fiber+husk (2:1, v/v), and sand media). The second factor was cutting materials derived from 1 year old seedlings (the upper shoots and the down shoots). The third factor was the concentration of growth regulators (0; 500; and 1,000 ppm of NAA). The root percentage was influenced by media, the shoots, and growth regulator NAA. Root length was influenced by media as a single factor and the interaction between media and the shoots. The number of leaves was influenced by the media, while the number of roots was not influenced by each single factor and their interactions. Media was a critical factor for the success of masoyi cuttings. Thus, the combination of soil+sand (2:1, v/v) media with the upper shoots is a recommended treatment for masoyi shoot cuttings, where the combination is not influenced by the growth regulator NAA. Keywords: Cryptocarya massoy, growth regulator, media, shoot cutting ABSTRAK Masoyi (Cryptocarya massoy) merupakan salah satu jenis tanaman penghasil hasil hutan bukan kayu (HHBK) endemik Papua bernilai ekonomi tinggi. Upaya pengembangan tanaman masoyi saat ini terkendala oleh sulitnya memenuhi kebutuhan bibit dalam jumlah banyak dan berkualitas. Untuk itu, perbanyakan secara vegetatif menjadi salah satu solusi permasalahan pemenuhan bibit. Penelitian bertujuan mendapatkan media tanam, bahan stek, dan dosis zat pengatur tumbuh NAA yang tepat untuk perbanyakan masoyi dengan cara stek. Penelitian menggunakan bibit berumur 1 tahun dengan Rancangan Acak Lengkap Faktorial. Faktor pertama adalah media tanam stek (tanah+pasir (2:1, v/v), serbuk sabut kelapa+ sekam (2:1, v/v), dan media pasir). Faktor kedua adalah bahan stek (bagian pucuk atas dan bagian pucuk bawah). Faktor ketiga adalah konsentrasi zat pengatur tumbuh (0 ppm, NAA 500 ppm, dan NAA 1.000 ppm). Hasil penelitian menunjukkan bahwa persen berakar dipengaruhi oleh faktor tunggal media tanam, bagian stek dan zat pengatur tumbuh NAA. Panjang akar dipengaruhi oleh faktor tunggal media tanam dan interaksi antara media dengan bagian stek. Jumlah daun dipengaruhi faktor media tanam, sedangkan jumlah akar tidak dipengaruhi masing-masing faktor tunggal dan interaksinya. Faktor media merupakan faktor penentu keberhasilan stek masoyi. Dengan demikian, kombinasi media tanah+pasir (2:1, v/v) dengan bagian pucuk atas merupakan perlakuan yang direkomendasikan untuk stek masoyi, dan kombinasi perlakuan tersebut tidak dip","PeriodicalId":103667,"journal":{"name":"Jurnal Penelitian Hutan Tanaman","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120948234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
