Abstract

Penelitian dilaksanakan di Laboratorium Ilmu dan Teknologi benih Fakultas Pertanian Untad dari bulan Maret – Juni 2013, dengan tujuan untuk mengetahui toleransi padi gogo lokal Mangkawa terhadap cekaman kekeringan berdasarkan karakter fisiologis dininya.  Penelitian ini merupakan penelitian eksperimental yang dirancang menggunakan rancanagn acak lengkap (RAL) dengan 5 taraf perlakuan yaitu : M0 = Tampa pemberian PEG 6000, M1 = larutan PEG 6000 – 1 bar, M2 =  larutan PEG 6000 – 2 bar,     M3 = larutan PEG 6000 -3 bar dan M4 = larutan PEG 6000 – 4 bar, setiap perlakuan diulangi sebanyak 5 kali sehingga terdapat 25 unit percobaan. Setiap unit percobaan menggunakan uji kertas digulung didirikan dalam plastik (UKDp) sebanyak 50 benih. Data hasil pengamatan di analisis dengan sidik ragam  (Uji-F), apabila hasil analisis ragam menunjukkan perbedaan nyata dilakukan uji lanjut beda nyata jujur (BNJ) pada taraf 5%.  Hasil penelitain ini berpengaruh nyata terhadap semua peubah pengamatan. Uji cekaman kekeringan dengan penggunaan larutan PEG 6000 menunjukkan bahwa tolok ukur kecepatan berkecambah, waktu berkecambah, prsentase kecambah normal, panjang plumula, rasio panjang akar per panjang plumula dan kandungan prolin bebas dapat mengindikasikan padi gogo lokal Mangkawa toleran terhadap kekeringan.

Abstract

Penelitian ini bertujuan untuk memperoleh informasi karakter kualitatif dan kuantitatif agar dapat ditemukan sifat-sifat genetik yang  baik pada padi gogo lokal asal Kabupaten Banggai. Karakterisasi dilakukan di Kebun Percobaan Sidondo, Kecamatan Biromaru, Kabupaten Sigi, Provinsi Sulawesi Tengah. Penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan 4 perlakuan genotip yaitu genotip Habo, Ranta, Sampara dan Landae’o, setiap perlakuan diulang 3 kali sehingga terdapat 12 satuan percobaan. Hasil penelitian menunjukan bahwa sebagian karakter kualitatif seperti warna lidah daun, warna leher daun, warna helai daun, warna batang dan ruas batang tidak terdapat perbedaan antara genotip padi gogo lokal asal Kabupaten Banggai yang diamati dan masing-masing genotip mempunyai keungulan di karakter kuantitatif antara lain genotip Habo (panjang daun dan persentase gabah berisi), genotip Ranta (jumlah anakan dan lebar daun), genotip Sampara (panjang malai, tinggi tanaman terpendek dan bobot 1000 biji) dan genotip Landae’o (umur tanaman terpendek). Karakter kuantitatif yang diamati relatif seragam dengan tingkat keragaman genetik yang rendah kecuali lebar daun (cukup tinggi) sehingga menyulitkan untuk dilakukan koleksi. Akan tetapi, nilai heritabilitas yang bervariasi memungkinkan genotip padi gogo lokal asal Kabupaten Banggai untuk dilakukan perbaikan sifat.

Abstract

Cocoa is one of the national commodity and plays an important role for the economy of Indonesia, especially in terms of farmer’s income and source of foreign exchange Cocoa seeds are recalcitrant i.e. prone to drought, sensitive to temperature and humidity. Cacao seeds have no dormancy, low storage capacity and sensitive to environmental changes. This study aimed to determine soaking time periods and concentration of gibberellin (GA3) for best cocoa seed viability. The study was conducted in the Seed Laboratory of Faculty of Agriculture, Tadulako University from March to April 2016.  It was arranged in a Completely Randomized Design with two factors. The first factor is the time length of soaking i.e. 2 h, 4 h, and 6 h while the second factor is the concentration of gibberellins i.e. 5 ppm, 10 ppm, and 15 ppm. Thus there were 9 treatment combinations and replicated 3 times resulting in 27 experimental units where each unit consisting of 20 grains of seed.  Data was analyzed using Variance Analysis and then continued with the Honestly Significant Difference if there is a significant effect.  The research results showed that the interaction effect between the length of time and the gibberellin concentrations is significant on root length but not significant on germination rate and root volume. Key Words : Soking time, and gibberellin concentration.
