Abstract

Maize productivity could be improved by using good quality of seed of high yielding hybrid varieties. The objective of this research was to study the effect of rhizobacteria and P fertilizer on physiological quality of maize hybrid seed and maize productivity. The experiment was conducted at Lembar Village, West Lombok District, West Nusa Tenggara Province and at Seed Science and Technology Laboratory IPB from April to December 2012. The experiment was arranged in a split plot design with three replications. The main plot was P fertilizer (untreated, 50 kg, 100 kg, 150 kg, and 200 kg SP36/ha), and the subplot was rhizobacteria treatments (untreated, rhizobacteria B42, and rhizobacteria ATS4). The results showed that application of 100 kg SP36/ha increased maize yield compared to that of unfertilized. Rizhobacteria ATS4 increased plant height and productivity of maize. Application of ATS4 rhizobacteria followed by 100 kg SP36/ha fertilizer increased the percentage of good quality seeds. Application of rhizobacteria could reduce the use of SP36 fertilizer up 50% of the recommended rate. Rizobakteri ATS4 and fertilizer P 100 kg SP36/ha increased the physiological quality of harvested seeds after four month storage at 21-25oC temperature and 53-62% relatif humidity.

Abstract

Matriconditioning using a solid carrier, Micro-Cel E, was applied on pepper seeds and its effects on the improvement of thermotolerance through the ethylene biosynthesis were studied. Untreated and matriconditioned seeds were soaked in 5 mM 1-aminocyclopropane-1-carboxylic acid (ACC) for various time at 25 oC to studies the time course of ACC-derived ethylene production. To study the performance of the seeds at high temperature, they were planted at temperature regime of 35 oC, 12h light/27 oC, 12h dark. The ACC-oxidase activity of the seeds after incubated in ACC at 35 oC was also determined. The ACC contents in untreated and matriconditioned seeds during the 24h imbibition period at 35 oC were monitored. No ethylene was detected during soaking of pepper seeds in the absence of ACC. In 5 mM ACC detectable levels of ethylene were produced; the matriconditioned seeds producing 10-fold larger amounts than the untreated seeds at the time of germination. It is postulated that matriconditioning greatly increases the ACC-oxidase activity at the time of germination. Matriconditioned seeds imbibed at 35 oC produced larger amounts of ACC and greater ACC-oxidase activity than the untreated seeds. Thus, the basis for the thermotolerance by matriconditioned seeds may be increasing ability to synthesize ACC and to utilize it for ethylene production and stress alleviation. Key words: ACC-derived ethylene production, ACC-oxidase, germination, preplant conditioning

Abstract

The objectives of this experiment were to analyze the endo- or exo-chitinase activities of healthy and Sclerotium rolfsii infected peanuts. The experiment analyzed 24 different peanut genotypes. Results of the experiment showed chromogenic dimer was the most suitable substrate for analysing chitinase activities. Both endo- and exo-chitinases activities were detected in leaf, stem, and crown tissues. Increased in chitinase activities were detected in S. rolfsii infected peanut tissues than in healthy plant. Regression analysis showed negative slope between disease intensity and chitinase activity in S. rolfsii infected peanut tissue (R2= 0.45). Key words: Disease response, stem rot disease, endo- and exo-chitinase

Abstract

The objectives of this experiment were to analyse physiological responses, such as oxidative burst reaction, peroxidase activity, and lignin content of healthy and S. rolfsii-infected peanut tissues. Differences in physiological responses among 24 peanut genotypes were determined, the disease severity was calculated and used to group resistance of tested genotypes. The regressions among observed peroxidase activity, lignin content and disease severity were used to determine the possible mechanisms of S. rolfsii resistance in peanut. Peanut seeds were grown in polybag and the growing plants were inoculated at the crown, stem, and leaf tissues. Results of the experiment indicated that infection of S. rolfsii in peanut did not induce oxidative burst. However, infection of the pathogen resulted in increased peroxidase activity and lignin content in the infected tissues. Regression analysis between peroxidase activity and disease severity showed negative slopes, indicating the more resistance the genotype, the more peroxidase activity in the tissue. Regression analysis between lignin content and disease severity was not significant. Key words: hypersensitive response (HR), resistance mechanisms, Sclerotium stem rot, disease response, Arachis hypogaea

Abstract

This research was held from April to July 2012, located in the seed processing unit of PT Astra Agro Lestari Tbk, Central Borneo. The study consisted of three experiments, the first experiment to determine the effect of water temperature and immersion intensity of seed germination. The first experiment used completely randomized design (CRD) factorial with two factors, water temperature: 27, 60, 70, 80, 90oC and immersion intensity: 1x24, 2x24, 3x24 hours. The second experiment used a single factor of CRD namely ethephon concentration: 0, 0.4, 0.8, 1.2, 1.6%. The third experiment was a continuation from the second experiment with the adding heat drying treatment during a week. The result showed that 3x24 hours soaking treatment in 80oC hot water increased the germination, soaking in ethephon 0.4% inhibited radicle growth resulted abnormal seedlings. Soaking seed in 80oC hot water for 3x24 hours and followed by ethephon and then heat drying treatment for a week increased germination (52.0% maximum growth potential) but still ineffective to break seed dormancy.Key Words: breaking dormancy, ethephon, hot water treatment, oil palm seeds

Abstract

ABSTRAKSalah satu faktor yang menentukan daya simpan benih jahe putihbesar (JPB) adalah mutu. Mutu benih sangat ditentukan oleh tingkatkemasakan rimpang. Penelitian bertujuan untuk mengetahui pengaruhumur panen terhadap perubahan fisiologi dan viabilitas benih selamapenyimpanan. Penelitian dilaksanakan di Rumah Kaca dan LaboratoriumTeknologi Benih, Balai Penelitian Tanaman Rempah dan Obat sertaLaboratorium Pascapanen IPB Bogor, mulai bulan Juli 2012 sampaidengan Februari 2013. Rancangan yang digunakan adalah acak lengkap(RAL) dengan lima ulangan. Perlakuan yang diuji adalah tiga tingkat umurpanen benih 7, 8, dan 9 bulan setelah tanam (BST). Pengamatan dilakukanterhadap perubahan fisiologis (penyusutan bobot, persentase rimpangbertunas, tunas, kadar air, dan laju respirasi), serta viabilitas rimpang benih(daya tumbuh, tinggi, dan bobot kering bibit). Hasil penelitianmenunjukkan rimpang benih umur 7 dan 8 BST mempunyai daya simpanterbaik karena menghasilkan masing-masing total angka penyusutan bobotlebih rendah (24,65 dan 25,25%) dan tunas lebih pendek (0,30 dan 1,08cm) dibandingkan dengan umur panen 9 BST (27,13% dan 1,62 cm),selama 4 bulan disimpan. Masa dormansi rimpang benih JPB mulai pecahsetelah mengalami periode simpan 2 bulan. Pertumbuhannya mulaiseragam setelah 3 bulan simpan. Umur panen jahe 7 dan 8 BSTmempunyai derajat dormansi yang lebih tinggi dibanding 9 BST. Rimpangbenih umur panen 7, 8, dan 9 BST mempunyai daya tumbuh tinggi (>95%)dan pertumbuhan bibit seragam setelah 3 bulan disimpan.Kata kunci: Zingiber officinale Rosc., penyimpanan, benih, perubahanfisiologis, viabilitasABSTRACTOne of the factors that determine the storability of seed rhizome ofwhite big ginger (WBG) is quality. The quality is determined by thematurity levels of seed rhizome. The aim of the experiment was to observethe effect of harvesting time on physiological changes and seed viability ofWBG seed rhizomes during the storage. The experiment was conducted atGreen House and Seed Technology Laboratory of Indonesian Spice andMedicinal Crops Research Institute, Bogor and Postharvest Laboratory,IPB, from July 2012 to February 2013. The experiment was arranged in acompletely randomized design with five replications. The treatmentstested were three levels of WBG seed rhizome harvesting time: 7, 8, and 9month after planting (MAP). Variables observed were physiologicalchanges of seed rhizomes during the storage (weight loss, sproutingpercentage, shoot height, respiration rate, and moisture content) andviability (growth ability, height, and dry weight of the seedling). Theresults showed that seed rhizomes at 7 and 8 had the best storability, sinceit was produced each low rate of weight loss (24.65 and 25.25%), andshoots shorter (0.3 and 1.08 cm) than 9 MAP (27.13% and 1.62 cm), for 4months in storage. Dormancy of WBG seed rhizomes has been brokenafter 2 months in storage. Harvesting at 7 and 8 showed a degree ofdormancy higher than the harvesting age 9 MAP. Harvesting time at 7, 8,and 9 MAP had high growth ability (> 95%) and uniform seedling growthafter 3 months in storage.Keywords: Zingiber officinale Rosc., storage, seed, physiologicalchanges, viability

ABSTRAKSalah satu kendala dalam produksi jahe putih  besar (Zingiber treatments tested were five types of rhizomes, control (2-3 vegetative officinale Rosc.) adalah tingginya kebutuhan benih yaitu sekitar 2 juta ton buds), mother rhizome, primary rhizome, secondary rhizomes, and tertiary per ha. Efisiensi penggunaan benih tanaman telah dilakukan melalui penelitian yang bertujuan untuk menentukan karakter awal rimpang yang berhubungan/berkorelasi dengan viabilitas benih rimpang dan peluang perbanyakan jahe dengan menggunakan satu jenis rimpang. Percobaan ini dilaksanakan di rumah kaca dan laboratorium benih Balai Penelitian Tanaman Rempah dan Obat, Bogor pada bulan Mei 2014 sampai Agustus 2014. Benih tanaman berasal dari jahe putih besar yang dipanen pada umur 9 bulan. Rancangan yang digunakan adalah rancangan acak kelompok dengan 4 ulangan. Perlakuan yang diuji yaitu lima jenis rimpang  yaitu kontrol (2-3 propagul), rimpang induk, rimpang primer, rimpang sekunder, dan rimpang tersier. Pengamatan karakteristik awal rimpang/mutu fisik (bobot, diamater, panjang dan kekerasan) dilakukan terhadap masing-masing jenis rimpang. Mutu kimia meliputi kadar pati, kadar serat, kadar air, kandungan hormon GA3 dan hormon IAA serta laju respirasi. Peubah yang diamati untuk menduga viabilitas benih yaitu daya tumbuh yang diukur 1 BST (bulan setelah tanam). Viabilitas potensial benih yaitu tinggi tunas,  jumlah  tunas,  jumlah  daun,  bobot  kering  tunas,  bobot  basah rimpang, bobot kering rimpang, panjang akar bobot kering akar diamati pada 1,5  BST.  Data  awal (karakter  fisik  dan  fisiologis  rimpang) dikorelasikan dengan viabilitas benih. Hasil penelitian menunjukkan bahwa  kadar  pati  berkorelasi  positif  dengan  viabilitas  benih (daya tumbuh).  Viabilitas  benih  berkorelasi  negatif  dengan  karakter  fisik rimpang (bobot, kekerasan, dan diameter). Rimpang induk mempunyai kadar pati dan kekerasan yang tinggi. Kontrol yang selama ini digunakan sebagai   kriteria   benih   mempunyai   daya   tumbuh   rendah.   Efisiensi penggunaan rimpang dapat dilakukan menggunakan satu jenis rimpang (satu propagul). Rimpang induk, primer, sekunder dan  tersier yang terdiri atas satu propagul dengan bobot rimpang antara 20 dan 40 g dapat digunakan sebagai sumber benih.Kata kunci:  Zingiber  officinale  Rosc,  efisiensi  benih,  jenis  rimpang, korelasi, viabilitas benih Correlation Among Physical, Physiological Characters of Rhizome Type and Viability of Large White Ginger (Zingiber officinale     Rosc.)ABSTRACTOne  of the problems  in the  large white ginger  production  of (Zingiber officinale Rosc.) is high requirement for seed rhizome (± 2 ton per ha).
