Abstract

Abstrak Penelitian ini bertujuan mengamati pengaruh lama perendaman biji dengan 1% EMS terhadap persentase munculnya bibit dan karakter pertumbuhan tanaman cabai rawit pada umur 4 minggu setelah tanam (MST). Benih cabai rawit direndam dalam air selama 6 jam, selanjutnya direndam 1% EMS dalam buffer fosfat pH 7, selama 6 jam, 9 jam dan 12 jam. Tiap biji disemai dalam bumbungan kertas. Munculnya bibit diamati setiap hari. Setelah berumur 3 minggu, bibit dipindahkan ke bedengan. Hasil menunjukkan perlakuan 1% EMS memperlambat munculnya bibit. Pada 10 hari setelah semai (HSS) munculnya bibit pada perlakuan dapat mencapai 100%. Perlakuan 1% EMS berpengaruh nyata terhadap tinggi tanaman dan jumlah daun, sedangkan panjang, dan lebar daun dengan perendaman 6 jam tidak berbeda dengan kontrol, namun berbeda dengan perendaman 9 jam dan 12 jam. Kata kunci : EMS, bibit, pertumbuhan, Capsicum frustescens L.   Abstract This research aimed to evaluate the influence of different exposure durations of 1% EMS on seedling emergence and growth characters of C, fustescent at 4 week after planting (WAT). Seeds were soaked in water for 6 hours, then soaked in 1% EMS in phosphate buffer pH 7, for 6 hours, 9 hours and 12 hours. Each seed was then sowed in a single paper tube. Seedling emergence was observed every day. At 3 weeks after sowing, seedlings were transferred to field. Results showed that soaking seeds in 1% EMS inhibited seedling emergence. At 10 days after sowing, the percentages of seedling emergence at control and treated seed were 100%. Treatments of 1% EMS have a significant effect on plant height, and the number of leaf, while length, and width of leaf with 6 hour exposure were not different with control, but differ from exposure of 9 hours and 12 hours. Keywords: EMS, seed emergence, growth, Capsicum frutescens L.

Abstract

Abstrak Tanaman bawang putih (Allium sativum L.) adalah tanaman holtikultura yang memiliki banyak manfaat terutama umbinya yang umumnya digunakan sebgai bumbu dan obat. Salah satu kultivar bawang putih yang ditanam di Bali adalah ‘Kesuna Bali’ yang hanya memiliki satu siung.  Salah satu cara untuk memperbaiki karakter tanaman adalah dengan cara induksi mutasi kromosom dengan kolkisin. Penelitian ini bertujuan menganalisis pengaruh perlakuan kolkisin terhadap indeks stomata dan jumlah kromosom dari tanaman ‘Kesuna Bali’. Penelitian menggunakan Rancangan Acak Kelompok dengan enam ulangan. Perlakuan kolkisin yang digunakan adalah 5%, 10% dan 20%. Hasil penelitian menunjukkan bahwa perlakuan kolkisin menurunkan indeks stomata dan meningkatkan jumlah kromosom. Kromosom triploid (2n=3x=24) dihasilkan pada perlakuan kolkisin 20%. Kata kunci : Allium sativum L., ’Kesuna Bali”, kolkisin, mutasi, sitologi Abstract Garlic (Allium sativum L.) is a horticultural crop that has many benefits, especially as spice and traditional medicine.  One of garlic cultivars planted in Bali is ‘Kesuna Bali’ which only has one clove. To improve characters of ‘Kesuna Bali’, modification of ‘Kesuna Bali’ properties can be done by means of induced mutation using colchicine.  This research aims to analyse the effect of colchicine on stomata index and the number of chromosomes of 'Kesuna Bali'. This research used randomized block design with six replicates. In this experiment the concentration of colchicine used were 5%, 10% and 20%. The results of this study showed that colchicine treatment of 20% resulted in the lowest stomata index and there was an increase in chromosome number. Colchicine at concentration of 20% resulted in triploid chromosome set (2n = 3x = 24). Keywords: Allium sativum L., ’Kesuna Bali”, cholchicine, mutation, cytology

Abstract

Abstrak Cekaman kekeringan merupakan faktor pembatas penting bagi pertumbuhan dan produktivitas tanaman termasuk padi.      Penelitian ini bertujuan menganalisis respon padi IR64 terhadap cekaman kekeringan dengan pemberian polietilen glikol (PEG) pada fase reproduktif.  Penelitian juga bertujuan menganalisis ekspresi gen aquaporin akibat cekaman kekeringan.  Bibit padi ditanam dalam pot dan perlakuan PEG dengan konsentrasi 108g/L (-0.25MPa) dan 178g/L (-0.52 MPa) diberikan saat munculnya panikula. Perlakuan diberikan selama 2 minggu, kemudian tanaman disiram kembali.  Ekspresi gen diamati pada akhir perlakuan dengan semi kuantitatif real time PCR.  Ekstraksi RNA menggunakan RNeasy plant mini kit, sedangkan sintesis cDNA menggunakan Transcriptor First Strand cDNA Kit.  Hasil penelitian menunjukkan bahwa jumlah malai dan berat total malai berkurang akibat cekaman kekeringan.  Persentase gabah kosong mencapai 84,6% pada perlakuan PEG-0,52 MPa, sedangkan pada perlakuan PEG -0,25 MPa persentase gabah kosong sebesar 67,8%.  Pada kontrol persentase gabah kosong adalah 10,3%.  Ekspresi gen OsPIP2;7 sedikit menurun pada perlakuan PEG -0,52 MPa.Kata kunci: ekspresi gen, IR64, kekeringan, padi, PEG  Abstract Drought stress is one of the limiting factors of plant growth and productivity including rice.  The aim of this study was to analyze responses of IR64 rice to polyethylene glycol (PEG)-induced-drought stress at the reproductive stage.  This study also aimed to analyze the expression of aquaporin under drought stress.  Rice seedlings were grown in pot system and PEG treatment at concentration of -0.25MPa (108g/L) and -0.52 MPa (178g/L) were given when the panicles arose.  Treatments were conducted for 2 weeks, after that the plants were rewatered.  Gene expression was evaluated at the end of PEG treatment using semi quantitative real time PCR. RNA was extracted using RNeasy plant mini kit, while cDNA synthesis was done using Transcriptor First Strand cDNA Kit.  The results showed that the number and weight of rice ear were less in plant treated with PEG than in control.  The percentage of empty rice grain reached 84.6% at PEG -0.52 MPa, while at PEG -0.25 MPa the percentage of empty grain was 67.8%.  In control plant, the percentage of empty grain was 10.3%.  Drought stress did not alter the expression of OsPIP2;7.  Keywords: drought, gene expression, IR64, PEG, rice
