Abstract

Effect of invigoration on seed viability and plant growth of kenaf (Hibiscus cannabinus I.)I aw vigour and viability of seed is the main factor causing the low productivity of crops. One of the methods of improving a deteriorating seed is in vigoratioo. The study was aimed at evaluating the effect of invigwation treatment on seed viability, plant growth and yield of kenaf (Hibiscus cannabinus). The experiment was conducted in two steps. The irst step was conducted in the laboratory of the Research Institute for Tobacco and Fibre Crops. Malang from Januai to April 1998 and the second step was conducted at Asembagus Expeimental Farm from Januai to May 1998. The experiment in the laboratory was designed as a completely randomized design while the field expeiment was done as a randomized block. The treatments were arranged factoially The irst factor was the seed vigour (growth uniformity) i.e. 40 or 60%, and the second factor was tnvigoration treatment, i.e control (untreated), water, sodium phosphate (2x10 M), sodium thiosulphatc ( 2 x 10 M), or tannic acid (2 x 10"* M). Results showed that invigoration treatments were not effective, when they were applied on the seed of 40% vigour. On the seed of 60% vigour, the invigoration improved seed vigor and viability. Treating the seed of 60% vigour with sodium phosphate (2x10 M) improved growth uniformity by 20% and potential viability by 7%, while applying the seed with sodium thiosulphnte decreased elcctroconductivity by 24.59 Mmhos/g compared to the control. Furthermore, treating seed of 60% vigour with sodium phosphite improved plant stand by 7 33%. increased plant height by 19 an. stem diameter bv 2 cm and fresh stem per plot (9at ) by 633 kg.

Abstract

Cimanggu progeny clove has been distributed to almost of centre production, such as in Sumedang. However, their genotypes are still unidentified. Therefore, clustering cloves accession population in Sumedang is necessary. The objectives of this study is to cluster and determine phylogenetic relationship of Cimanggu progeny clove population in Sumedang base on morphological characters. The experiment was conducted in Sumedang (West, Java) from 2013 until 2014, by using 10 selected accessions (healthy, more than 40 years old, productivity is ≥ 20 kg dried flower). Variables were observed include morphological leaf, flower and flower production. To distinguish genotype from each accession was conducted by cluster analyzed, while to identify the variables which were related to the clusters formation, used correspondence analysis. The results indicated, that clove population Sumedang can be classified into three clusters as followed: the first cluster are Syar 43 and 46 accessions, characterized by greenish orange and greenish purple of young leaves tip with flower tube greenish red (GR 180B), the second cluster are Syar 44 and 45 accession, characterized by tip reddish purple young leaves and greenish red (GR181B) flower tubes color, and the third cluster are Syar 47, 49, 50, 51 and 52 accessions, characterized by orange young leaves tips and greenish red (GR180C) flower tubes. This information can be utilized to support releasing Cimanggu clove variety.Keywords: Syzygium aromaticum, clustering, characters, morphology

Abstract

Morphological and physiological characteristics of Vinca at di fferent water stress levelsVinca (Vinca rosea L.) is one of the important medicinal crops as the sources of raw materials for traditional medicines. Its alkaloid is believed can reduce the risk of cancer, blood tension and diabetes diseases. Recently, vinca is only grown as ornamental plant in the garden, therefore, its cultivation methods is limited, especially its water stress tolerance, lite purpose of this experiment was to study the effect of water stess on the morphological and physiological characteristics of vinca. A pot experiment was conducted in the plastics house of the Research Institute for Spice and Medicinal Crops from November 1997 to March 1998. Factorial experiment consisted two factors and three replications was arranged in a randomized block design. Ihe irst factor consisted of two vinca varieties, those wee white flowers (WFV) and red flowers of vinca (RFV). While 4 different levels of water stress i.e., (I) 100% ield capacity (FC), (2) 80% FC, (3) 60% FC, and (4) 40% FC were used as the second factor. Parameters used for evaluating the effect of teatment consisted of morphological characteristics such as (I) plant height, (2) number of primary branches, (3) number of leaves, (4) leaf area (5) dry weight of stem, (6) dry weight of leaf, (7) dry weight of flowers and (8) dry weight of roots, and physiological characteristics observed including: (I) percentages of opened stomata and (2) free proline content of leaf. Results showed that interaction between varieties and water stress did not significantly affect the morphological nor physiological characteristics. Varieties significantly affected the morphological characteristics (except plant height), however they did not signiicantly affect physiological characteristics. Water stress significantly affected the morphological (except dry weight of roots) and free proline contents. Under 80% FC, vinca produced the highest growth and dry weight of plant however, the plant growth and dry weight wee inhibited under 60 and 40% FC. Under 40% FC, percentages of opened stomata deceased signiicantly. Moeover, proline content in the leaves signiicantly increased by water stess treatments.

The diseasespread widely over all pepper producing areas in Indonesia. Integratedpest managements are suggested to reduce the economic loss due to thedisease. Recently, breeding program has been developed in Indonesiathrough hybridization to find out promising accessions resistant to foot rotdisease. The objective of the present study was to evaluate the resistanceof F1 progenies obtained from polination of various parents to foot rotdisease. Among 400 accessions of black pepper obtained from breedingprogram, 15 accessions were selected based on previous evaluation. ThreePhytophthora isolates were used as tester in the study. The research wascarried out in laboratory and glass house of Indonesian Spice andMedicinal Crops Research Institute, from January to December 2005. Invitro screening was carried out by inoculating detached third and fourthleaves of each accession. The leaves were set in boxes abaxial surfacefacing up, while wet tissue papers were used to retain air humidity in thebox. The lower leaf surface of each pepper accession was inoculated witha piece of Phytophthora colony then incubated in room temperature. Thewidth of necrotic areas was measured with leaf area meter after the leaveswere incubated for 72 hours. Each treatment was replicated 5 times. Ingreen house experiment, 4 month seedlings of each accession wereinoculated with 50 ml of zoospore suspension (10 5  zoospore/ml), replicated3 times, and each replication consisted of 5 seedlings. The number ofinoculated seedlings was counted after one month of incubation. Bothexperiments were arranged using factorial design with two factors: pepperaccession and Phytophthora isolate. There was no significant interactionbetween black pepper accession and the Phytophthora isolates, neither invitro nor green house. Nine accessions showed disease severity less than20%, and accession number 27-1, 36-31, and 4-5L showed disease severitybelow 10% in both experiments. To obtain better progeny resistant to stemrot disease and more stable, it is suggested to continue this pollinationprogram by using those promising accessions.Key words: Piper nigrum L., Phytophthora, resistance, pollination

Abstract

To produce while pepper using traditional method, the ripe berries are soaked in a river or a pond for 10-14 days prior to decorticating. To improve the traditional method. Research Institute for Spice and Medicinal Crops has designed pepper decorticator to support the white pepper processing. This decorticator has a good function, hut its performance still need to be improved, as it still produces high percentage of white pepper damage. This experiment was aimed to at improving (he performance of the pepper decorticator. The experiment was conducted from July to Ocktobcr 1999 and divided into two steps i.e. preliminary and main experiment. The treatments applied on Ihe main experiment were (I) disc diameter (18, 20, and 22 cm) and (2) rubber elasticity (5.34, 7.74, 9.79, and 15.02 N/mm). The experiment was designed as a completely randomized, arranged factorially in three replications. The pepper variety used for the experiment was Lampung Daun Lebar. The disc distance of pepper decorticator in this experiment was set at 3.5 cm based on the preliminary experiment. Results showed that the optimal disc diameter and nibber elasticity was 20 cm and 7.74 N/mm respectively. Decorticator performance on the optimal condition were : decorticated pepper 97.25%, white pepper damage as pepper defect 2.46% and as broken pepper 1.98% respectively and the capacity of decorticator was 42.27 kg/hours. In general, the quality of while pepper produced met the National Standard of Indonesia.
