Abstract

Abstrak Penelitian tentang perkembangan aerenkim pada kangkung darat dan kangkung air telah dilakukan pada bulan Oktober 2014 sampai Februari 2015 di Laboratorium Struktur Perkembangan Tumbuhan Jurusan Biologi Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Andalas. Jaringan akar diproses dengan metode parafin, kemudian dideskripsikan secara kuantitatif. Rongga aerenkim pada kangkung air terbentuk pada minggu ke tiga dengan jumlah dua rongga sel sedangkan pada kangung darat terbentuk pada minggu ke empat. Proses pembentukan aerenkim terjadi melalui proses pelisisan sel korteks.Abstract Research of aerenchyma development on terrestrial kale Ipomea reptans poir and water kale Ipomoea aquatic Forsk was conducted from October, 2014 until February, 2015 at Laboratory of plant growth structure, the Faculty of Math and Science, Department of Biology, Andalas University. Kales were analyzed by using paraffin method then described by quantitive data. Results showed: (i) aerenchyma cavities were formed in the 1st week, (ii) aquatic Forsks with two cell cavities were formed in the 3rd week, (iii) terrestrial kales were formed in the 4th week. The formation process of aerenchyma occurred through lysis process of cortical cell.

Abstract

AbstrakPenelitian tentang pertumbuhan bibit surian (Toona sinensis (Juss,) M. Roem pada tanah ultisol yang dicampur pupuk kompos dengan penambahan Fungi Mikoriza Arbuskula (FMA) telah dilakukan pada bulan November 2014 sampai April 2015 di Rumah Kaca dan Laboratorium Fisiologi Tumbuhan, Jurusan Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Andalas, Padang. Penelitian ini bertujuan untuk mengetahui pertumbuhan bibit surian pada media tanah ultisol yang dicampur pupuk kompos dengan penambahan FMA. Penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 6 ulangan. Perlakuannya adalah tanpa inokulasi (hanya pupuk organik), 5 g inokulan per tanaman, 10 g inokulan per tanaman, 15 g inokulan per tanaman. Hasil penelitian menunjukkan bahwa pertumbuhan bibit surian pada media tanah ultisol yang dicampur pupuk kompos dengan penambahan FMA memberikan pengaruh nyata terhadap pertambahan diameter batang.Abstract Study on the seedling growth of surian inoculated with some doses of Arbuscular Mycorrhizal Fungi (AMF) on ultisol mixed compost has been conducted from November 2014 until February 2015 in the Greenhouse and Plant Physiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, Andalas University, Padang. The aim of this study was to find the growth of surian seedling that inoculated with some dosages of AMF on ultisol mixed compost. The study used a Completely Randomized Design with four treatments and six replications. The treatments were done without inoculation, 5 g inoculants/ plant, 10 g inoculants/ plant, 15 g inoculants/ plant. Result of this study indicated that AMF given on ultisol soil gave significant effect on increasing stem diameter of surian seedlings.
