Abstract. Prayoga GP, Aini SN, Mustikarini, ED, Rosalin Y. 2020. Diversity of black pepper plant (Piper nigrum L.) in Bangka Island (Indonesia) based on agro-morphological characters. Biodiversitas 21: 652-660. Black pepper (Piper nigrum L.) production in Bangka Belitung Islands Province continued to decrease in 2014-2017. Efforts to increase black pepper production was carried out by providing superior varieties that began with an increase in the genetic diversity of black pepper plants. Increasing the genetic diversity of black pepper can be done through black pepper germplasm exploration activities followed by characterization. The research aimed to obtain the agro-morphological characteristics of black pepper plants in Bangka island. Exploration was carried out by survey method in four regencies in Bangka Island. The research method used a survey method with convenience sampling technique. Observation of agro-morphological characters was carried out in accordance with the descriptor for black pepper from IPGRI (1995). The results of exploration of black pepper plants in Bangka Island have found 9 accessions of black pepper plants, consisting of 5 cultivars were Lampung Daun Lebar (LDL), Lampung Daun Kecil (LDK), Chunuk, and Jambi and 4 landraces namely Bogor, Peremis, Keriwil, and Merapin Daun Kecil (MDK). There were morphological differences in 9 accessions of black pepper plants, namely leaf lamina shape, leaf vein, leaf margin, lateral branch habit, leaf base shape, ripe fruit color, hanging vines, ground vines, and stem shape. Agro-morphological relationship of 9 accessions of black pepper plants can be divided into 5 clusters at a 50% similarity level. Based on this study, black pepper breeding program on Bangka Island could be done accessions of Peremis, Bogor, Nyelungkup, and Jambi as genetic sources. Furthermore, selection would be better to use length of petiole, length of stem segment, fruit size, percentage of perfect fruit, weight of 1000 fruits, and the weight of 1000 dried seeds as the selection criteria.

The cause of stunting disease of black pepper (Piper nigrum) in Indonesia has not yet been confirmed cither due o a virus or mycoplaam. However, similar disease found on black pepper plants in the Southeast Asia is caused by Piper yellow mottle virus (PYMV) which is transmitted by Planococcus citri. This expeiments was aimed o examine the cause of the stunting disease and its insect vectors. The expeiment were conducted from October 1998 to May 2001. Diseased vegetative materials of black pepper plants showing stunting disease were collected from Sukamulya, Sukabumi. The potential insect vectors were collected from black pepper plants in Bogor, IP Sukamulya (Sukabumi), Lampung and Bangka. The insects were fed on the diseased plants obtained from Lampung, Bogor and IP Sukamulya, then transferred o the healthy plants. The healthy plants were produced rom true seeds and cutings oiginated rom Bogor and IP Sukamulya. The tested plants were incubated at the green house and examined for disease development. Diseased leaf samples collected rom black pepper plant rom IP. Sukamulya and the transmitted plants were sent to the University of Minnesota, USA for Ihe virus (PYMV) by using ISEM (immunosorbent electron microscope). The result snowed that the leaves samples rom IP. Sukamulya were infected by PYMV. The morphology and size of the virus were similar to those caused stunting disease in the South East Asia. Potential insects vectors found on the diseased black <br /><br />pepper plants were two mealybugs, P. minor and Ferrisia virgata (Hemiptera; Coccoidca: PaaidbcoccidaeX aa well as an aphid Toxoptera aurantii (Hemiptera: Aphidoidea: Aphididae). The first tial on disease transmission by using P. minor, previously reared on the potato tubers, showed one out of ten tested plants produced disease sympom. The subsequent trial using P minor, bred on healthy black pepper seedlings, showed thee out often tested plants developed disease symptoms. None of the aphid transmitted plants developed Ihe disease. This study confirmed thai PYMV b the cause of stunting disease on black pepper in IP Sukamulya and Lampung and P. minor as the insect vecor of the disease.<br /><br />

ABSTRACT Plants of black pepper (Piper nigrum L.) may display changes in their photosynthetic activity as a result of environmental seasonal changes. Intercropping with tree species may represent an alternative to mitigate the impacts of climatic changes on crops. The objective of this work was to evaluate the physiological responses of photosynthesis in black pepper plants under different shade levels promoted by intercropping with rubber trees (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg. The photosynthetic performance in black pepper along the day was evaluated under full sun and five shade levels. The resulted showed that variations positives in leaf gas exchanges were not exclusively dependent on the shade promoted by the distance in relation with the line of rubber trees in the field, but also fluctuate depending on the period of the day, the orientation (Northern or Southern), relating the line of trees and the season of the year. This study showed that shaded intercropped plants displayed some advantage in a few cases (black pepper plants located at 2 m, and 5 m between rubber trees, southern side) as regards the photosynthetic rate at midday and afternoon, and especially in summer, when compared to pepper plants cultivated in full sunlight condition, That would be likely related to the to the maintenance of somewhat lower temperature and higher relative humidity in the atmosphere close to the black pepper plant implying some advantage for such consortium system to mitigate the possible effects of future climate changes, like warming.

Wild pepper of Piper colubrinum Link is used as rootstocks for grafted black pepper (Piper nigrum/Piper colubrinum) because its resistance to fungi that cause root rot disease. Grafted black pepper nurseries and plantations began to be developed by farmers in Lampung. This research aims to study the growth characteristics of wild pepper and grafted black pepper plants. The research was conducted in the field of wild pepper and grafted black pepper owned by farmers in Air Kubang Village, Air Naningan District, Tanggamus, Lampung, using survey method. Plant samples were determined randomly in the fields. The results showed that: (1) Wild pepper plants starts at the age of 1 year form plagiotropic branches with small diameters every 1-2 orthotropic branches, but slowly form orthotropic branches; (2) After the second pruning (of harvesting cuttings) 22% of the plants form orthotropic branches. The yield of pepper cuttings from the first to third harvests increased by 21-25% compared to the previous yield. In the third harvest, the production of cuttings reached 5066 cuttings (2 nodes) per 400 m2 land area or equivalent to 126,650 cuttings per ha of land harvested every 2 months; (3) At the age of 18 months, compared to non-grafted, grafted black pepper showed a greater greeness leaf index, larger stem diameter, larger plagiotropic branch diameter, higher number of orthotropic and plagiotropic branches, and 15.6% of grafted black pepper plants were flowering. Key words : Black pepper, cutting, flowering, growth, grafting, Piper colubrinum

Abstract. Rahayu, Fatimah, Bae EJ, Mo YG, Choi JS. 2020. Genetic diversity and morphological characteristics of native seashore paspalum in Indonesia. Biodiversitas 21: 4981-4989. Seashore paspalum (Paspalum vaginatum) is a warm-season turfgrass indigenous to tropical and coastal areas worldwide. The objectives of this study were to measure the genetic diversity and genetic variation of Indonesian seashore paspalum germplasm. Three turf quality, six morphological characters, and ten SSR (microsatellite) markers were used to assess genetic relationships and genetic variation among 22 germplasm resources from Indonesia and one commercial variety (Salam) from United States of America. The results showed significant variation for five morphological characters among 23 tested seashore paspalum accessions. The cluster analysis of morphological characters of 23 seashore paspalum accessions using 0,6 cut off divided into three morphological types: tall high-density, intermediate, and dwarf low-density ecotype. The genetic variation revealed 22 alleles with average number of alleles per locus was 2 and polymorphism information content (PIC) values average was 0.33. The microsatellite marker cluster analysis showed that 23 seashore paspalum accessions were grouped into two major groups, with a genetic similarity coefficient was 0,72. The low level of genetic diversity occurred among Indonesia natural grass germplasm and the genetic distance was relatively low between Indonesian germplasm and Salam variety. The genetic diversity and morphological characteristics will be useful for further study and utilization of Indonesian seashore paspalum germplasm.

The study’s objective was to determine the effect of the NO3-: NH4+ratio and types of support on NPK uptake and pepper plant growth in field conditions. The study used a completely randomized block design with three replications. The first factor was the type of support, being the deadwood and living supports in the form of Gliricidia sp. and Ceiba pentandra. The second factor was the ratio of N fertilizer forms, which were 100% NO3-, 100% NH4+, 50% NO3-:50% NH4+, 75% NO3-:25% NH4+ and 25% NO3-:75% NH4+. The results have demonstrated that the uptake of N, P, and K, as well as the plant growth, were not affected by the interaction of the N fertilizer form ratio with the types of support. In field conditions, the black pepper prefers the N fertilizer in the form of 50% NO3-:50% NH4+. The pepper plants that were given N fertilizer in a combination of 50% NO3-:50% NH4+ have demonstrated an N, P, and K uptake, and morphology and plant dry weight were higher than the ratio of other forms of N fertilizers.

Stem cutting is the common planting material for black pepper (Piper nigrum L.) farmers mainly because the method is cheap, easy to obtain, and produces satisfactory number of new plantlets, which are relatively genetically uniform to their parent. However, soil propagation of stem cuttings renders both the stem and developing roots susceptible to soil borne pathogens, ultimately compromising the quality of the plant. Good quality rootstock of the new plant promotes faster, safer, and better black pepper plant establishment. Hydroponic farming thus offers a good platform for producing quality rootstock of the new plants and has gained importance to many farmers due to its flexibility in manipulating plant growth conditions and timely pathogen management, thus safer, healthier, and faster growth. This study investigated the growing media suitable for rootstock growth of P. nigrum L. cv. ‘Kuching’ and compared the rooting ability between stem cuttings with adventitious roots at the time of planting and stem cuttings without any root at the time of planting. In a laboratory setting, a total of 210 stem cuttings were hydroponically planted in seven nutrient compositions, with each nutrient composition containing an equal number of stem cuttings with adventitious roots at the time of planting and stem cuttings without any root at the time of planting. Hoagland solution supplemented with 0.005 mM potassium silicate solution (T4) and Hoagland solution supplemented with 2 mM salicylic acid solution (T6) showed faster root initiation whereas T1 (Hoagland solution only) produced the highest increment in root length followed by T6. The least suitable nutrient composition was T5 [T4 + 6 mL of 1 M Ca (NO3)2.4H2O solution]. The total number of roots was highest in plants from stem cuttings which had some adventitious roots at the time of planting, whereas roots in plants from stem cuttings which did not have any root at the time of planting, increased in root length faster than plants withstem cuttings which had adventitious roots at the time of planting.

North Lampung Regency is the main producer of Lampung black pepper, which is generally in the form of a poly-culture system of pepper cultivation. This study aims to study the performance and productivity of the pepper plant which is intercropped with coffee by farmers in North Lampung. This study used a survey method and conducted in North Lampung by taking 2 samples of the sub-districts purposively, namely Abung Barat and Abung Tengah. From each district, 2 villages were selected purposively. Primary data were collected by interviewing 93 sample farmers who were randomly sampled. To deepen the performance of planting, visits and observations of farmers' fields were conducted. The results of this study concluded that: (1) 96% of farmers applied a poly-culture pepper plantation system. Intercropping pepper plantations have a lower pepper plant population but the presence of intercropping can cause land use efficiency to increase by up to 30%;(2) The poly-culture pepper fields  are managed less intensively as indicated by the low fertilizer dosage and the high mortality rate of pepper, which reaches 7-10% of plants per year; (3) The productivity of this intercropping system is pepper yield (conversion of SPH 1600 trees / ha) reaching 230-260 kg / ha or based on factual population reaching 155-267 kg/ha, coffee yield 166-221 kg/ha, and yield of Pithecellobium jiringa 24 -28 kg/tree; (4) According to farmers' perceptions, the main constraints faced by farmers (80.2% of farmers) were the attack of pepper foot rot disease, low prices for pepper, and high mortality of pepper trees. However, most farmers (88.9% of farmers) said they would not replace pepper with other crops.Keywords: Black pepper, coffee, Pithecellobium jiringa, poly-culture, yield
