Abstract

Abstrak Salah satu permasalahan dalam perbanyakan tanaman cendana secara generatif yaitu perkecambahan biji yang lambat (dormansi), sehingga diperlukan upaya untuk mempercepat perkecambahan dengan pemberian Zat Pengatur Tumbuh (ZPT). Tujuan penelitian ini untuk mengetahui pengaruh jenis ZPT terhadap perkecambahan benih cendana. Penelitian dilakukan di Laboratorium Institut Pertanian Malang, mulai bulan Oktober sampai Desember 2017, menggunakan metode eksperimen. Rancangan yang digunakan ialah acak lengkap (RAL) dengan 5 perlakuan yaitu ; Kontrol menggunakan air tanah, air kelapa muda konsentrasi 70%, simplisia kecambah kacang hijau konsentrasi 70%, simplisia tomat konsentrasi 70% dan asam giberelat (GA3) konsentrasi 70%. Pengamatam perkecambahan benih cendana meliputi Kecepatan berkecambah, daya kecambah, panjang plumula dan berat basah benih cendana. Data yang diperoleh dianalisis menggunakan analisis ragam pada taraf kepercayaan 95% menggunakan Program SPSS statistics 24.0. Hasil penelitian menunjukkan bahwa penggunaan jenis ZPT terhadap perkecambahan benih cendana berpengaruh nyata terhadap semua parameter. Penggunaan ZPT GA3 menghasilkan pertumbuhan terbaik pada parameter kecepatan berkecambah dan berat basah dan berbeda nyata dengan perlakuan yang lain. Pada parameter panjang plumula, penggunaan GA3 tidak berbeda nyata dengan penggunaan air kelapa muda. Sedangkan untuk parameter daya kecambah, penggunaan GA3 tidak berbeda nyata dengan penggunaan air kelapa muda dan penggunaan simplisia tomat. Perlakuan yang menghaslikan rata-rata terendah adalah penggunaan air tanah (kontrol). Abstract Problems in the propagation of sandalwood plants are generative germination is slow because the seeds have dormancy, so it takes effort to accelerate germination with the provision of Plant Growth Regulator (ZPT). The purpose of this study was to determine the effect of several type of plant growth regulator on germination sandalwood seeds. The study was conducted at the Central Laboratory of the Malang Institute of Agriculture (IPM) from October to December 2017, using experimental methods. The design used was complete randomized (RAL) with 5 treatments, namely: Control using ground water, 70% coconut water concentration, simplicia of green bean sprouts concentration 70%, simplicia of tomato concentration 70% and giberelin acid (GA3) concentration 70%. The germination monitoring of sandalwood seeds include germination rate, germination, plumula length and wet sandalwood weight. The data obtained were analyzed using variance analysis at 95% confidence level with the SPSS statistics 24.0 program. The results showed that the use of several plant growth regulator substances to germination of sandalwood seeds significantly affected the germination rate, germination, plumula length and wet sandalwood seed weight. The use of GA3 plant growth regulator resulted in the best growth in germination rate parameters and the wet weight and significantly different from other treatments. In the plumula length parameter, GA3 usage having not significantly different with young coconut water treatment. While for germination parameter, GA3 usage not significantly different with young coconut water usage and tomato simplicia. The treatment of the lowest average is ground water usage (control).
