Abstract

Pepper is an introduced species and has always been propagated vegetatively, so it has narrow genetic base. High genetic diversity is necessary to produce new varieties, especially for breeding of resistance to foot rot disease. Increasing genetic diversity can be done through gamma ray irradiation. This research aims to evaluate response of black pepper Ciinten variety at seed and radicle emergence phases to gamma ray irradiation. The research was conducted in PAIR BATAN and greenhous e IMACRI from June 2014 to April 2015. The plant material was Ciinten variety at the seed and radicle emergence phases. The experimental design used was completely randomized design (CRD) with one factor which is dose of irradiation with seven levels (0, 25, 50, 75, 100, 125, 150) Gy. Each treatment consisted of three replications, each replication consisted of 60 seeds. Both phases showed significant differences in perfomances between dose in plant height, leaf length, number of leave, number of internode. Radiosensitivity of pepper on radicle emergence phase was higher than the seed phase indicated by LD50 (Lethal Dose 50). LD50 at seed phase was 68.15 Gy, whereas LD50 of the radicle emergence phase was 30 Gy. The higher irradiation dose that given to both treatment phases caused reduction in plant height, leaf length, while the number of leaves and nodes decreasing. Irradiation dose 25 dan 50 Gy in seed phase and 25 Gy in radicle emergence phase significantly increase genetic diversity base on quantitative, qualitative characters, anatomy and leaf resistence to P. capsici infection. Eighteen putative mutants resistant to infection P. capsici. Eighteen mutant putative Ciinten pepper varieties were expected to be high yielding varieties with more research in the greenhouse and in the field to determine the production and quality potential.

Abstract

Response To The Growth of (Pepper nigrum L.) In Different Number of Segment  and Planting Media. Pepper are propagated vegetatively by stem cuttings. The number of planting material segments and planting media can support technology of pepper seeds. The good pepper cuttings are strong, healthy, and free of disturbing organisms so it will produce healthy and strong plant. This study was aim to analysis the pepper growth in different segments and media. The study was conducted in January to December 2018 in Balittro's greenhouse. The study used factorial randomized block design (RBD). The first factor is the number of segments, namely one segment and two segments. The second factor plant media, namely (1) soil, (2) cocopeat, (3) charcoal husk, (4) sand, (5) sand: soil (1: 1), (6) soil: manure (2: 1), (7) soil: manure: cocopeat (2: 1: 1), (8) soil: manure: husk charcoal (2: 1: 1). One and two segments of pepper cuttings can be used as vegetatif propagation. Optimal use of cuttings for pepper seed is one segment cuttings. The growth of one segment cuttings at 6 MAP was not significantly different from that of two segment cuttings, on the parameters of leaf length and width, as well as root length and internode length, so that the use of one segment cuttings for pepper seed production can save the use of planting material as a seed source, making it more efficient and economical. Composition of plant that can be used as an alternative are soil: manure: husk charcoal (2: 1: 1), soil: manure: cocopeat (2: 1: 1) which has a higher value on the variable plant height, length, width and number of leaves. Keywords: cutting, cocopeat, husk charcoal, pepper ABSTRAKTanaman lada diperbanyak secara vegetatif melalui setek batang. Jumlah buku dan media tanam yang tepat dapat menjadi pendukung dalam teknologi penyediaan benih lada yang baik. Mutu benih setek lada yang baik yaitu benih kokoh, sehat, dan bebas organisme pengganggu sehingga akan menghasilkan pertumbuhan tanaman yang baik. Tujuan dari penelitian adalah mengetahui respons pertumbuhan setek lada pada jumlah buku dan media tanam yang berbeda. Penelitian dilaksanakan pada bulan Januari hingga Desember 2018 di rumah kaca Balittro. Penelitian menggunakan rancangan acak kelompok (RAK) faktorial. Faktor pertama adalah jumlah buku yaitu satu buku dan dua buku. Faktor kedua adalah media tanam (1) tanah, (2) cocopeat, (3) arang sekam, (4) pasir, (5) pasir : tanah (1:1), (6) tanah : pupuk kandang (2:1), (7) tanah : pupuk kandang : cocopeat (2:1:1), (8) tanah : pupuk kandang : arang sekam (2:1:1). Hasil penelitian menunjukkan bahwa perbanyakan benih dengan menggunakan setek lada satu buku dan setek  lada dua buku dapat digunakan sebagai bahan perbanyakan. Penggunaan setek optimal untuk benih lada adalah stek satu buku. Pertumbuhan setek satu buku pada 6 MST tidak berbeda nyata dengan setek dua buku, pada parameter panjang  dan lebar daun, serta panjang akar dan panjang ruas, sehingga penggunaan setek satu buku untuk produksi benih lada dapat menghemat penggunaan bahan tanam sebagai sumber benih, sehingga lebih efisien dan ekonomis. Media tanam yang dapat memberikan respon pertumbuhan yang baik yaitu pada peubah tinggi tanaman, panjang, lebar dan jumlah daun serta  dapat dijadikan media alternatif adalah komposisi; tanah : pupuk kandang : arang sekam (2:1:1), dan komposisi; tanah : pupuk kandang : cocopeat (2:1:1)Kata kunci: arang sekam, cocopeat, setek, lada

Abstract

Lada merupakan komoditas ekspor yang menguntungkan dan kaya manfaat. Hal ini menyebabkan permintaan benih lada yang berasal dari setek batang meningkat. Untuk memenuhi permintaan benih lada dibutuhkan peningkatan keberhasilan hidup setek batang. Salah satu caranya yaitu penggunaan zat pengatur tumbuh (ZPT). Beberapa ZPT akan diujikan pada lima aksesi lada hasil iradiasi sinar gamma. Aksesi ini membutuhkan waktu sekitar tiga minggu untuk menumbuhkan akar atau tunas. Penelitian ini bertujuan untuk mengetahui respons pertumbuhan aksesi lada hasil iradiasi sinar gamma terhadap zat pengatur tumbuh Rootone F dan air kelapa. Penelitian dilaksanakan pada bulan Januari – Juni 2020 di Rumah Kaca Balai Penelitian Tanaman Rempah dan Obat (Balittro), Bogor. Rancangan yang digunakan adalah Rancangan Acak Kelompok dua faktor. Faktor pertama adalah jenis aksesi yang terdiri dari lima jenis yaitu MP1, MP2, MP3, MP4 dan varietas Ciinten. Faktor kedua adalah ZPT yang terdiri dari tujuh taraf yaitu Rootone F 0.5 g, Rootone F 1 g, Rootone F 1.5 g, air kelapa 25%, air kelapa 50%, air kelapa 75% dan tanpa ZPT (kontrol). Hasil penelitian menunjukkan bahwa respons aksesi MP3 dan MP4 memiliki jumlah tunas, tinggi tunas, jumlah daun, panjang daun, dan lebar daun lebih baik daripada varietas Ciinten. Respons perlakuan ZPT Rootone F 0.5 g memiliki daun lebih lebar dan jumlah daun lebih banyak dibandingkan dengan air kelapa 75%, namun tidak berbeda nyata dengan kontrol pada umur 7 MST. Terdapat interaksi ZPT dan aksesi yang diuji dimana seluruh kombinasi memiliki persentase hidup >75% kecuali perlakuan Rootone F 1.5 g aksesi MP1 memiliki persentase hidup nyata lebih rendah.
