Abstract

The pineapple vegetative propagation method using crown leaf bud cuttings has potential to produce seedlings of greater uniformity and in larger quantities than other methods. This study, aimed to explore the potential eff ects of concentration and frequency of Benzylaminopurine (BAP) application for increasing the production and quality of pineapple seedlings from crown leaf bud cutting propagation. The experiment used a randomized complete block design (RCBD) with two factors. The fi rst factor was the concentration of BAP (0, 200, 400, 600, 800 ppm) and the second factor was the frequency of BAP application (1, 2, 3 times). Furthermore, this study investigated the eff ects of applying mycorrhizae to accelerate seedling growth and improve seedling quality during production from crown leaf bud cutting propagation. The experiment used a RCBD with one factor (dose of mycorrhiza: 0, 50, 100, 150, 200 spores). The results indicated that the eff ects of concentration and frequency of BAP application and their interaction increased seed production as determined by sprout cuttings at 5 weeks after planting by applying 600 ppm 2 times. Generally, with increasing concentration and frequency of BAP application, leaf chlorophyll content was reduced. However, the application mycorrhiza positively infl uenced the production of seedlings from pineapple crown bud cuttings and improved seedling quality as measured by root dry weight, chlorophyll content, root infection, and phosphatase enzyme activity.

Abstract

Low seeds quality of the clove tree may attribute to the low national productivity of cloves in Indonesia.  The study aimed to determine the level of physiological fruit maturity and the effect of germination media on the viability of clove seeds. The study was performed at the Leuwikopo Seeds Storage and Quality Testing Laboratory and Leuwikopo Research Installation, Bogor, in October 2017 to December 2018. The material used was the Zanzibar clove seeds from ≥ 10 years old trees. The clove seeds obtained from a farmer’s plantation in Tolitoli District, Central Sulawesi. The study arranged in a split-plot design, with four replications, with the main plot was four levels of seed viability based on fruit colors: reddish-green, pink, red, and dark red. The subplots were three types of germination media, namely sand, cocopeat, and zeolite.  Thus, there were twelve treatments. Each plot consisted of 40 seeds for germination test and five seeds for water content determination. The results showed that the percentage of clove seeds viability negatively influenced by the level of fruit maturity based on the color of the fruit but was affected by the germination media. Good physiological quality of clove seeds characterized by dry seed weight of 2.70  g,  100 %  germination rate, vigor index of 73.75 %, and growth rate of 1.19 % etmal-1. Among the three types of germination media tested (sand, cocopeat, and zeolite), sand was the best germination media for clove seeds. Hence it is recommended to seeds producer.

Abstract

Permasalahan utama dalam pengembangan tanaman jahe putih besar (JPB) adalah   terbatasnya ketersediaan rimpang benih bermutu dalam jumlah yang mencukupi, pada waktu diperlukan oleh pengguna. Permasalahan tersebut antara lain disebabkan oleh produksi dan mutu rimpang benih yang masih rendah, serta bobot rimpang benih yang cepat menyusut dan mudah bertunassaat di penyimpanan. Penulisan ini bertujuan untuk menginformasikan kepada pengguna tentang karakter pola pertumbuhan, keseimbangan hormonal dan perubahan fisiologis yang menjadi faktor perhatian utama dalam peningkatan produksi dan mutu JPB melalui aplikasi zat pengatur tumbuh (ZPT).Peningkatan produksi dan mutu dapat dicapai dengan penggunaan rimpang benih  bermutu yang diperoleh  melalui: penentuan pola pertumbuhan, pengaturan keseimbangan hormon, baik secara alami (pengaturan iklim mikro), maupun dengan pemberianZPT selama proses produksi di lapangan dan di penyimpanan. Beberapa hasil penelitian membuktikan bahwa: (1) Pola pertumbuhan tajuk dan rimpang JPB selama pembentukan dan perkembangannya secara umum diklasifikasikan atas  tiga fase yaitu: fase lambat 1–4 bulan setelah tanam (BST), cepat (> 4–6 BST), dan pemasakan (> 6 BST).Rimpang benih JPB umur 7 BST sudah dapat digunakan sebagai bahan tanaman. (2) Perbedaan lokasi tanam dan umur panen mempengaruhi pola keseimbangan hormon endogen tanaman (rasio hormonABA/GA dan ABA/sitokinin (Zeatin) dan mutu rimpang benih JPB. Rasio ABA/sitokinin (zeatin) yang lebih tinggi pada rimpang benih umur 7 BST (5,0) dan 8 BST (4,7) dibanding rimpang benih umur 9 BST (4,2) untuk rimpang benih asal Nagrak, sehingga mampu memicu dan mempertahankan dormansi sehingga benih JPB lebih tahan disimpan.  (3) Periode dormansi benih rimpang JPB pecah setelah disimpan selama 2 bulan dan merupakan periode kritis atau periode yang tepat untuk aplikasi perlakuan penundaan pertunasan. (4) Aplikasi PBZ 400 ppm meningkatkan produksi JPB yang dinyatakan dalam bobot basah (22%) dan jumlah rimpang cabang (68%), dengan karakter rimpang: kecil, ruas pendek dan bernas, serta meningkatkan mutu dan daya simpan dibanding tanpa PBZ. (5) Aplikasi PBZ 1000 ppm, pada suhu ruang simpan 20 – 22 ºC, dapat menekan susut bobot sebesar 15% dibanding kontrol, setelah disimpan selama 4 bulan dan dapat menekan persentase rimpang bertunas sebesar 26% setelah 3 bulan disimpan.Permasalahan utama dalam pengembangan tanaman jahe putih besar (JPB) adalah   terbatasnya ketersediaan rimpang benih bermutu dalam jumlah yang mencukupi, pada waktu diperlukan oleh pengguna.

Its caused by the production and quality of seed rhizomes are still low, and the seed rhizomes weight are rapidly shrinking and sprouting when in the storage. This Overview aims to inform users about the character of the pattern of growth, the balance of hormonal and physiological changes that are primarily focused on the production and seed quality improvement BWG through the application of plant growth regulator (PGR). Increased production and quality can be achieved by the use of quality seed rhizomes obtained through: determination of growth patterns, hormonal balance regulation, both naturally (microclimate regulation), as well as by application of growth regulators (ZPT) during the production process in the field and in storage. Some research results showed that: (1) The growth pattern of the canopy and GWB seed rhizomes during its formation and development is generally classified into three phases: slow phase 1-4 months after planting (MAP), fast (> 4-6 MAP), and maturty (> 6 BST). (2) Differences in planting location and harvest age affect the balance pattern of plant endogenous hormones (ABA / GA and ABA / cytokinin (zeatin) hormone ratios) and the BWG seed rhizomes quality. ABA / cytokinin ratios are higher in BWG seedlings aged 7 MAP (5.0) and 8 MAP (4.7) compared to 9 MAP (4.2) for seed rhizomes from Nagrak, so they are able to trigger and maintain dormancy so Its are more resistant to storage. (3) The dormancy period of BWG seed rhizomes break after stored for 2 months and this is a critical period or an appropriate period for sprouting inhibition treatment. (4) Application of PBZ 400 ppm increased production and quality of BWG seed rhizomes, namely: wet weight (22%) and number of branch rhizomes (68%) with rhizome characteristics: small, short and filled out internodes compared without PBZ. (5) Application of PBZ 1000 ppm, at a storage temperature of 20-22 ºC, can reduce weight loss by 15% compared to control, after stored for 4 months and also can reduce the sprouting percentage of rhizomes by 26% after stored for 3 months.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh perlakuan pelapisan benih menggunakan bakteri Bacillus subtilis, Serratia marcescens, dan Pseudomonas kelompok fluorescens terhadap viabilitas dan daya simpan benih jagung manis (Zea mays saccharataSturt.). Penelitian disusun dengan rancangan petak tersarang (Nested Design) dengan petak utama adalah periode simpan minggu ke 0, 3, 6, 9, 12, 15, 18, 21, dan 24 dan anak petak adalah perlakuan coating dengan bakteri Bacillus subtilis, Serratia marcescens, Pseudomonas kelompok fluorescens, dan kontrol. Hasil penelitian menunjukkan adanya interaksi yang sangat nyata antara perlakuan coating benih dan periode simpan terhadap daya berkecambah, berat kering kecambah normal, kadar air, dan populasi bakteri. Perlakuan coating benih dan periode simpan menunjukkan interaksi yang nyata terhadap indeks vigor benih. Tolok ukur kecepatan tumbuh benihhanya dipengaruhi oleh faktor tunggal periode simpan. Benih yang dilapisi bakteri menghasilkan nilai berat kering kecambah normal yang nyata lebih baik daripada benih tanpa coating. Benih tanpa coating memiliki nilai daya berkecambah sebesar 56.7% pada periode simpan 24 minggu. Benih yang dilapisi bakteri Bacillus subtilis dapat mempertahankan daya berkecambah hingga 64.0% sampai periode simpan 24 minggu, sedangkan Serratia marcescens mampu mempertahankan daya berkecambah hingga 60.0% . Berdasarkan tolok ukur daya berkecambah, pelapisan benih menggunakan bakteri Bacillus subtilis dan Serratia marcescens merupakan perlakuan pelapisan benih yang potensial untuk lebih dikembangkan. Bakteri Bacillussubtilis lebih mampu bertahan hidup selama penyimpanan dibanding dengan bakteri Serratia marcescens maupun Pseudomonas fluorescens.  Populasi bakteri Bacillus subtilis sampai dengan periode simpan 24 minggu adalah 14.2 × 104 cfu g-1.

Abstract

Tujuan penelitian ini adalah untuk mempelajari pengaruh priming dalam mempertahankan vigor benih kacang panjang selama dalam penyimpanan. Perlakuan priming yang dilakukan adalah perendaman benih dalam air, KNO3, CaCl2, asam askorbat, dan pelembapan diantara kertas selama dua jam. Perlakuan priming menyebabkan peningkatan kadar air benih hingga sekitar 9%, sedangkan perlakuan pelembapan diantara kertas hanya meningkatkan kadar air 1-2 % dibanding kontrol. Setelah selesai perlakuan, benih dikeringkan kembali hingga kadar air 12-13% lalu disimpan di ruang kamar(26-30.8 °C; RH 68-77 %) dan AC (±20 °C; RH ±50%) menggunakan plastic polipropilen (tebal 0.08 mm). Perlakuan priming mampu mempertahankan indeks vigor dan kecepatan tumbuh sampai dengan 15 minggu penyimpanan baik pada penyimpanan ruang AC ataupun kamar. Perlakuan perendaman dalam air  dapat menjadi pilihan terbaik sebagai perlakuan benih sebelum simpan karena murah dan mudah dilakukan serta memberikan hasil yang baik.

Abstract

The objective of this experiment is studying the effect of physical scarification of nutmeg seed coat and germination media to accelerating germination rate and enhancing nutmeg seed viability. This experiment was conducted in December 2013 until May 2014 at Leuwikopo Experimental Field’s green house and Seed Laboratory  of  Agronomy  and  Horticulture  Department,  Faculty  of  Agriculture,  Bogor  Agricultural University. This experiment was using factorial randomize complete block design with 3 replications. The first factor was physical scarification on the seed coat with three levels: without scarification, one hole scarification on seed’s base, and two holes scarifications on seed’s base. The Second factor was the seed germination substrate that consist of sand, charcoal of husk rice, and mixture of sand and compost 1:1 (v/v). The results showed that two holes physical scarification could enhance germination process according to the earlier appearance of roots and shoot. Sand as the germinating substrate was observed as a better substrate according to the parameters of germinating potency and shoot height. Two holes physical scarification treatment which was sowed in sand substrate showed the increase of lateral root number into 6 lateral roots. Nutmeg seedling growth from sand substrate seedling showed a better growth than the charcoal of husk rice substrate seedling by evaluating these parameters on stem diameter, seedling’s height, amount of leaves, canopy’s width, and leaves colour.
