Abstract

ABSTRACT‘Kristal’ guava fruit can easily be deteriorated during storage. The objective of this experiment was to study the effect of the waxing on the shelflife and quality of the ‘Kristal’ guava fruit. Experiment was conducted at the Postharvest Laboratory of Departemen of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University from February to May 2016. The experiment was designed using completely randomized design (CRD) with single factor consisted of 5 treatments, i.e., 0% of beewax (control), 2% of beewax, 4% of beewax, 6% of beewax and 8% of beeswax. The results showed that beewax coating suppressed weight loss and softness of fruit compared to the control fruit during storage period. Beewax coating did not significantly affect chemical quality such as soluble solids content, titratable acidity and vitamin C. The beeswax coating with 2% and 4% were able to extend shelflife of ‘Kristal’ guava fruit 9 days longer as compared to the control.

Abstract

ABSTRACTPummelo productivity is still low, therefore efforts should be made to increase its flowering and production. The objective of study was to determine the effectiveness of strangulation combined with the application of breaking dormancy substances to improve flowering of pummelo. The experiment was conducted in January to November 2015, at the Cikabayan Experimental Research Station, IPB. The carbohydrate and nitrogen analysis was done in laboratory of Postharvest Agriculture Research Institute, Bogor. Three-year-old pummelo grown in field was subjected for this research. Experiment used a completely randomized design (CRD) with two factors. The first factor was treatment to stimulate flowering, consisted of 3 levels i.e. single strangulation, double strangulation and control, and the second factor was the use of dormancy breaking substances, consisted of 3 types i.e. KNO3, Ethepon and BAP. Strangulation was performed by pressing the wire with a diameter of 2.0 mm into stem as deep as the diameter of the wire. Strangulation was done simultaneously and then released after 3 months. Dormancy breaking substance was applied immediately after releasing the wire for strangulation with the concentration of 200 ppm KNO3, 100 ppm Ethepon or 100 ppm BA. Treatments were replicated 4 times. The results showed that single and double strangulation treatments for 3 months were an effective way to induce flowering of young pummelo trees. Double strangulation produced more flowers as compared to single strangulation.Increased carbohydrate content and C/N ratio in leaves were observed on flower induced trees. Strangulation treatment for 3 months can increase flowering of young pummelo trees. Application of dormancy breaking substances did not have any effect on flowering induction in pummelo.Keywords: carbohydrate content, dormancy breaking substance, flower induction, pummelo, strangulationABSTRAKProduktivitas pamelo masih rendah sehingga perlu upaya peningkatan pembungaan dan produksinya. Penelitian ini bertujuan untuk mengetahui efektivitas strangulasi yang dikombinasikan dengan aplikasi zat pemecah dormansi dalam meningkatkan pembungaan jeruk pamelo. Penelitian dilaksanakan pada bulan Januari sampai Nopember 2015, bertempat di Kebun Percobaan IPB Cikabayan. Analisis karbohidrat dan nitrogen dilakukan di laboratorium BB Pasca Panen, Bogor. Percobaan menggunakan tanaman jeruk pamelo “Nambangan’ berumur 3 tahun dengan Rancangan Acak Lengkap (RAL) dua faktor. Sebagai faktor pertama yaitu perlakuan untuk menstimulasi pembungaan, terdiri atas 3 taraf perlakuan yaitu perlakuan strangulasi tunggal, strangulasi ganda dan kontrol, dan sebagai faktor kedua adalah penggunaan zat pemecah dormansi terdiri atas 3 jenis yaitu KNO3, Ethepon dan BAP. Masing-masing perlakuan diulang 4 kali sehingga terdapat 36 unit percobaan. Strangulasi dilaksanakan dengan melilitkan kawat dengan diameter 2.0 mm pada batang dengan menekan kawat ke batang sedalam diameter kawat tersebut. Strangulasi dilakukan serentak pada batang, strangulasi dilepas setelah 3 bulan kemudian. Zat pemecah dormansi diaplikasikan segera setelah pelepasan kawat strangulasi dengan konsentrasi masing-masing 200 ppm untuk KNO3, 100 ppm untuk Ethepon atau 100 ppm untuk BAP. Hasil penelitian menunjukkan perlakuan strangulasi selama 3 bulan merupakan cara efektif menginduksi pembungaan tanaman jeruk pamelo. Perlakuan strangulasi ganda menghasilkan bunga lebih banyak dibandingkan dengan strangulasi tunggal. Tanaman yang telah terinduksi menunjukkan tingginya kandungan karbohidrat pada tajuk tanaman sehingga meningkatkan rasio C/N. Perlakuan zat pemecah dormansi tidak memberikan pengaruh yang nyata terhadap pembungaan jeruk pamelo.Kata kunci: kandungan karbohidrat, pamelo, pembungaan, strangulasi, zat pemecah dormansi

Abstract

The aim of this research was to study the relationship between fruit drop  and contents of auxin, polyamines, ACC, total sugar, and starch. Cultivars of mango used were Gadung 21 and Lalijiwo.The persisting fruit and abscising fruits were used to quantify auxin, polyamine, ACC, total sugar, and starch.  The content of polyamine and ACC was determined on pericarp, auxin on seed, whereas the content of starch and total sugar was determined on mesocarp. The result of research showed that fruit drop was preceded by low content of auxin that increased the sensitivity of abscission zone to ethylene.  The increased sensitivity of abscission zone to ethylene was supported by low content of polyamine and  high content of ACC. The abscising fruit has high content of starch, but low in  total sugar content.   Key words : Mango, persisting fruit, abscising fruit, auxin, polyamine, ACC, total sugar, starch

Abstract

Indonesia has high variety of pummelo [Citrus maxima (Burm.) Merr.], but only several cultivar are cultivated extensively. Others became vurnerable and the  germplasm has to be conserved to prevent their extinction. One of the conservation method is in vitro conservation  using a slow growth technique. Factorial experiment was used in designing the experiment, the first factor was MS medium concentration, i.e. 1/2MS and MS. The second factor was sucrose concentration, i.e. 0; 1; 2; and 3%. The results showed that low concentration of MS medium and sucrose reducing the leaf number and shoot length but increasing the root number and length.  Based on inhibition of growth,  the most reducing growth was planlet on MS without sucrose.

Abstract

Carnation has a highly economic demand of cut flower in Indonesia.  Field observations in West Java Indonesia was conducted in order to find the typical mottle symptoms that was a suspect caused by a virus disease. Identification of the virus was respectively conducted by performing ELISA test with four anti sera and characterizations held by bioassay, observing of virion particles, detecting of nucleic acid by RT-PCR and nucleotide sequencing. Total of 403 samples were collected from plants with or no virus-like symptoms. Among those all tested, 83% were found to be infected by Carnation mottle virus (CarMV), but negatively against Carnation ringspot virus (CRSV), Carnation laten virus (CLV), and Carnation vein mottle virus (CVMV) antisera. By mechanical inoculation, the virus was able to infect systemically Cenopodium quinoa and locally infect on others. However on Phalaenopsis sp and Gomprena globosa, there was symptompless found. The isometric CarMV particles size was approximately 30 nm. RT-PCR using specific primers of CP gene of CarMV successfully amplified a DNA sized 1000 bp.  CarMV West Java Indonesian (Idn-WJ) isolates possessed the highest nucleotide and amino acid homology with CarMV from Spain and was in the same cluster with CarMV from China, Taiwan and Israel.Keyword: Dianthus caryhophyllus, RT-PCR, sequence, Tombusviridae
