Abstract

Proper storage period and medium is essential in order to keep the scion of rubber plant in a good condition, so that the budding success rate can still be maintained as high as possible. The objective of this study was to determine the effect of storage periods and media of scion on the success level of green budding and its water content in the rubber plant. This experiment was conducted at Pakuwon experimental garden with altitude of 450 m above sea level, Latosol type of soil, and B type of climate according to the classification of Schmidt and Fergusson, from January to July 2014. Randomized complete block design in single factor with nine treatments and three replications was used in this study. The nine treatments used were: (1) storage of scion for 2 days without media, (2) Two days stored with moistened newsprint paper, (3) Two days stored with moistened sawdust media, (4) Two days stored with moistened cocopeat media, (5) Four days stored without media, (6) Four days stored with moistened newsprint paper, (7) Four days stored with moistened sawdust media, (8) 4 days stored with moistened cocopeat media, and (9) without storing/control (K). The results showed that the storage of rubber scion for 2-4 days can reduce the success level of green budding due to the decrease in water content of scion. In condition when scion had to be stored, it should be a maximum of 4 days by using moistened newspapers or sawdusts storage media. Both of the storage media can still maintain the water content of scion at about 94.8% and 93.9%, respectively, compared to the water content of scion without storage treatment.

Abstract

Jarak yang jauh antara kebun entres dengan kebun produksi menyebabkan batang entres untuk okulasi hijau tanaman karet memerlukan proses penyimpanan dan pengangkutan. Oleh karena itu, teknologi penyimpanan dan pengemasan batang entres karet perlu diketahui. Tujuan penelitian adalah mengetahui pengaruh periode penyimpanan dan jenis pengemasan batang entres terhadap keberhasilan dan pertumbuhan okulasi hijau tanaman karet. Penelitian dilakukan di Kebun Percobaan Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar (Balittri), Sukabumi, mulai bulan Februari sampai Mei 2015. Rancangan yang digunakan adalah petak terpisah yang diulang 3 kali. Sebagai petak utama adalah 3 periode penyimpanan batang entres, yaitu 3, 4, dan 5 hari setelah panen. Sebagai anak petak adalah 4 teknik pengemasan batang entres: (1) kotak kayu dengan media 5 lapis kertas koran yang dibasahi dan batang entres tanpa kantong plastik, (2) kotak kayu dengan media serbuk gergaji yang dibasahi dan batang entres tanpa kantong plastik, (3) kotak kayu dengan media 5 lapis kertas koran dibasahi dan batang entres dibungkus kantong plastik, dan (4) kotak kayu dengan media serbuk gergaji dibasahi dan batang entres dibungkus kantong plastik. Peubah yang diamati adalah tingkat keberhasilan okulasi dan pertumbuhan tunas hasil okulasi. Hasil penelitian menunjukkan tingkat keberhasilan serta pertumbuhan tunas okulasi hijau dari batang entres karet yang disimpan selama 4 hari tidak berbeda nyata dengan yang disimpan selama 3 hari. Teknik pengemasan paling baik adalah berupa kotak kayu dengan media 5 lapis kertas koran atau serbuk gergaji yang dibasahi dan batang entres dibungkus kantong plastik.

Abstract

Perbanyakan karet (Hevea brasiliensis Muell. Agr.) dengan okulasi cokelat membutuhkan waktu yang lama dalam pembibitannya, sedangkan perbanyakan dengan okulasi hijau belum banyak dilakukan karena tingkat keberhasilan masih sangat rendah. Salah satu faktor yang diduga berpengaruh terhadap keberhasilan okulasi hijau adalah umur bibit batang bawah. Tujuan penelitian adalah mengetahui pengaruh perbedaan umur batang bawah terhadap persentase keberhasilan okulasi hijau pada tiga klon karet. Penelitian dilaksanakan di Kebun Percobaan (KP.) Pakuwon, Balai Penelitian Tanaman Industri dan Penyegar pada bulan Januari-Desember 2013. Penelitian menggunakan rancangan petak terbagi, tiga ulangan dan ukuran petak 25 pohon. Petak utama adalah jenis klon batang bawah, terdiri dari 3 klon, yaitu K1 = AVROS 2037, K2 = PB 260, dan K3 = GT 1. Anak petak adalah umur batang bawah terdiri dari 4 taraf, yaitu U1 = 4 bulan, U2 = 5 bulan, U3 = 6 bulan, U4 = 7 bulan. Okulasi dilakukan dengan cara membuka kulit batang bawah, kemudian entres dimasukkan ke dalam jendela sayatan hasil pembukaan. Pengikatan sambungan dilakukan dengan menggunakan plastik khusus dengan cara dililitkan dari bawah ke atas. Pengamatan dilakukan terhadap persentase keberhasilan okulasi hijau pada umur tiga minggu setelah okulasi (MSO). Hasil penelitian menunjukkan bahwa keberhasilan okulasi hijau pada tanaman karet dipengaruhi oleh umur batang bawah. Untuk Klon PB 260 dan GT 1, makin tua umur batang bawah sampai maksimum 7 bulan di polybag maka semakin meningkat persentase keberhasilan okulasi, sedangkan pada klon AVROS 2037 belum memperlihatkan perbedaan yang nyata.Kata kunci: Hevea brasiliensis, umur batang bawah, klon, keberhasilan okulasi hijauPropagation of rubber (Hevea brasiliensis Muell. Agr.) using brown budding need a long time in the nursery, whereas the propagation usinggreen Budding has not yet been done due to the success rate is still very low. One of the factorthat might influence the successfulness of green budding is rootstock age.. The purpose of this study was to determine the effect of different age of rootstock on the percentage of green budding success in three rubber clones. The experiment was conducted at the Pakuwon experimental station (ES), Indonesian Industrial and Beverage Crops Research Institute, from January-December 2013. The research was done using split plot design with three replications, and the plot size is 25 trees. The main plot was the type of clones used for rootstock that comprised of 3 clones: K1 = AVROS 2037, K2 = PB 260, and K3 = GT 1. Meanwhile, the subplots were rootstock age consists of 4 levels, namely: U1 = 4 months, U2 = 5 months, U3 = 6 months, U4 = 7 months. Observations were made on the percentage of green budding success at 3 weeks old after grafting . The results showed that the success of the green budding on the rubber plants is influenced by the age of rootstock. The use of rootstock up to 7 months old in polybag in PB 260 dan GT 1 clones would increase the percentage of grafting success, whereas AVROS 2037 clone did not show any significant different.

Abstract

One characteristic in determining the differences of fruit maturity levels in coffee is based on the difference in colour of epicarp or based on the ages of fruit that is calculated starting on a days after anthesis (HSA). In general, fruits in cherry level can result better germination than green level. This experiment was conducted at Pakuwon Experimental Station, Laboratory and Greenhouse of Indonesian Industrial and Beverage Crops Research Institute, Sukabumi, beginning from April until August 2013. The objectives of this study was to analyze the effect of varieties and fruit maturation stages on germinations and physical components of Arabica coffee seeds. The split plot design with three replications was used in this study. The main plot factors were four varieties of Arabica coffee i.e. Sigarar Utang, Kartika 1, S 795, and Kartika 2. While the split plot factors were four level of fruit maturation stages defined operationally by harvest fruit in cherry level (≈249 HSA), redish-yellow level (≈241 HSA), yellow level (≈233 HSA), and yellowish-green level (≈225 HSA). The results showed that the difference in coffee varieties and fruit maturation stages affect the germination speed of Arabica coffee seed. S 795 more faster to germinate than Sigarar Utang, Kartika 1, and Kartika 2. Similarly, fruit in the cherry level, redish-yellow, and yellow more faster to germinate than fruit in the yellowih-green level. Sigarar Utang has the highest in fresh weight of fruit and seed and dry weight of seed, and the lowest in seed water content, followed by S 795, Kartika 1, and Kartika 2. The germination success not only determined by seed physical quality components but is also influenced by environmental factors.

THE EFFECTS OF AGE AND STORAGE PERIODS ON THE GROWTH OF ROOTED CUTTINGS OF BLACK PEPPER ABSTRACT To provide good black pepper cuttings grown in polythene bags, it might be costly due to transportation cost should be covered into cost production. The use of rooted cuttings of black pepper is therefore considered as an alternative solution in providing of plant materials being ready to be planted in the fields. A research was carried out at a glass house of Sukamulya Research Station (Sukabumi) from January to Desember 2011. The objective of the study was to investigate the effects of age and storage periods of rooted cuttings on their freshness and growth performances under nursery condition. A randomized factorial design with three replications was used. The age of black pepper cuttings consisted of 1, 2, and 3 months old, while the storage periods were 0, 3, 5, 7 and 9 days. The number of pepper cuttings observed for their freshness levels were 50 cuttings per treatments, whereas those of their growth were 25 cuttings. For evaluation of their freshness, they were calculated based on the percentage of treated cuttings having water content of higher than 75%, while for their growth parameters observed were height of rooted cuttings, number of nudes, leaf length, leaf width, and length of internodes. The data were then analyzed with analysis of variance (anova) followed by HSD test level 5%. The results showed that there were noted interaction between the age and storage periods of rooted cuttings to the freshness and growth of young rooted cuttings. If farmers use rooted cuttings taken out from their polythene bags, then 2-month cutting olds with maximum storage periods of 5 days would give the best treated rooted cuttings having high in performance growth.

Abstract

Volume and type of growing media is important to support the growth of rubber seedling (Hevea brasiliensis) for rootstocks. The objective of this study was to determine the growth of rootstock and green budding success of rubber plants in different size of polybag and growing media. The research was carried out since January to December 2013 at the Pakuwon experimental garden, Parungkuda District, Sukabumi Regency, West Java. The study used a randomized block design (RBD) in factorial with two factors and three replications. The first factor is the sizes of polybag: (1) 30 ´ 20 cm, (2) 35 ´ 20 cm, and (3) 40 ´ 20 cm. Meanwhile, the second factor is the growing medium that consists of the mixture of soil and cow manure with 4 proportions: (1) 1 : 0, (2) 3 : 1, (3) 2 : 1, and (4) 1 : 1. Observations were made on the growth of pre-budding rootstock including seedling height, seedling diameter, number of leaves, and the success percentage of green budding. The results showed that the size of polybag has positive effect on the growth of the rubber seedling as rootstock at 6 months old after planting. Moreover, the use of large sizes of polybag (30 x 20–40 x 20 cm) was good for the growth of rootstocks that would be used for green budding. In addition, growing media that consisted of soil and cow manure at a comparison of 1 : 1 gave the highest effect on the growth of rootstock as well as the highest percentage of green budding success. However, there is no interaction between the size of polybag and growing media to the growth of rootstock and green budding success.
