Abstract

ABSTRAKPenelitian ini bertujuan untuk mengetahui pengaruh pemberian takaran terbaik hyponex merah terhadap sporulasi FMA lokal asal rizosfer kayu kuku. Penelitian dilakukan di Rumah Plastik Asosiasi Mikoriza Indonesia Cabang Sulawesi Tenggara dan Laboratotium Jurusan Kehutanan Fakultas Kehutanan dan Ilmu Lingkungan UHO selama bulan Mei-September dengan menggunakan Rancangan Faktorial Acak Lengkap (RAL) dua faktor yaitu faktor pertama  jenis FMA diantaranya Glomus sp. dan Acaulospora sp. dan faktor kedua yaitu hyponex merah diantaranya kontrol, 1 g/L, 2 g/L dan 3 g/L. Hasil Penelitian menunjukkan bahwa terjadi peningkatan kolonisasi dan sporulasi FMA Glomus sp. pada perlakuan tanpa pemberian hyponex seiring dengan waktu pengamatan. Jenis FMA Glomus sp. mampu meningkatkan nodulasi, jumlah daun dan berat kering tanaman seiring dengan meningkatnya takaran hyponex merah. Perlakuan tanpa pemberian hiponex merah cocok untuk perbanyakan Glomus sp. Kata Kunci:, Glomus sp.,Hyponex Merah, sporulasi

Abstract

ABSTRACTKalapi (K.celebica Kosterm.) is an endemic and endangered plant species in Sulawesi and categorize as monotypic species in the Fabaceae family. Kalapi, since 1998, listed as endangered. However, researches about kalapi still limited, such research that related to the handling of the seeds, the dimensions of fruits and seeds, as well as testing of physical quality of seeds has not been done. So that, the purpose of this study was to determine  handling of seeds, measuring the dimensions of fruits and seeds as well as testing of physical quality of seeds. Seed was collected from natural forest of Abuki, Village of Anggoro, District of Abuki, Konawe. Testing of physical quality of Kalapi was conducted at the Laboratory of Forestry, Faculty of Forestry and Environmental Sciences, Halu Oleo University, Kendari. Research was carried out for 4 months. Related to seed handling, technique to collect seed was by climbing and taking under trees. Physiologically, mature fruit has been colored brownish. Fruits that have been collected were stored in sacks and plastic. Fruits were extracted by using dry extraction. Based on, the dimensions of fruits and seeds observation, the length of the fruit averaged 7.081 cm (with ranged about 2.6-12.8 cm). While, the width of fruits has averaged 2.97 cm (with ranged about 1.7-4.6 cm). The mean length, width and thickness of each seed sized 11.33 mm (7.31-19.93 mm), 9.4 mm (5.99-11.90 mm) and 1.39 mm (0.7-2.02 mm), respectively. The number of seeds per fruit is 1-4 seeds. The average of purity of seeds that has been extracted is 99.51% with a range of 99.22-99.77%. Weight of 1000 of seeds grain is 99.1 g with a range of 91-103.6 g. Prediction of the number of seeds/kg is 10,113 grains of seeds / kg. Seeds moisture content is 13.12% with range of 11.3-13.12%. This research will support and provide important data about kalapi related to their seeds. Keywords: K. celebica Kosterm, character of seed physical, dimension of fruit and seed, Abuki.
