Abstract

Gmelina arborea is one plant spacies that is widely planted in smallholder forests in Bondowoso, East Java. This research was conducted in the framework of the selection of seed sources that can be developed for proiduksi quality seeds. The results showed that a relatively equitable distribution of forest people in four districts with three patterns that monoculture, mixtures and intercropping with agricultural crops. Parent tree bole height average of 10.60 m with a trunk diameter/ 25.39 cm dbh. there are 2 types of fruit is round and slightly oval with the number of seeds per kilogram of grain in 1872 and 1000 grain weight of seed on average 538.75 grams indicates the variation differed significantly between the parent tree.Key Words: Gmelina arborea; seed trees; selection; smallholder forest

Abstract

Gmelina arborea Roxb. adalah salah satu jenis tanaman yang banyak dikembangkan di Indonesia namun informasi tentang variasi antar  populasi sebaran masih terbatas. Penelitian ini dilakukan untuk mengetahui variasi benih dari beberapa populasi sebaran di Indonesia.Penelitian ini menggunakan rancangan acak lengkap/RAL dengan perlakuan 6 asal populasi yaitu Sumedang,Lampung, Bondowoso, Mataram,  Bogor dan Bantul. Setiap perlakuan menggunakan sampel benih sebanyak 40 butir biji dan diulang sebanyak 5 kali. Hasil penelitian menunjukkan bahwa asal populasi sebaran menunjukkan variasi yang nyata pada karakter panjang benih, diameter benih, berat 1000 butir benih dan jumlah benih per kilogram. Rata-rata panjang benih berkisar antara 15,22 – 17,06 mm, diameter benih 8,57 – 9,68 mm, berat 1000 butir benih  518,74 – 657,47 gram dan jumlah benih per kilogram 1528 -1940 butir. Berat 1000 butir benih terbaik adalah dari populasi Sumedang sedangkan jumlah benih per kilogram terbanyak dari populasi Bogor.
