Abstract

ABSTRACTUpland rice cultivation required specific cultivation, particularly the use of crop varieties that have good water-use efficiency or varieties that are able to adapt to the conditions of limited water availability. The aim of this study was to describe characters of morphology and physiology related to water use efficiency of upland rice varieties. The research was conducted from October 2013 to April 2014 in the greenhouse IPB Experimental Station Cikabayan, Bogor. The research was arranged in randomized block design with two factors. The first factor was 5 upland rice varieties (Inpago 5, Batutegi, Jatiluhur, Inpago 8 and Sarinah). The second factor was 4 irrigation intervals which were 3, 6, 9, and 12 days. Characteristics assosiated with water saving of upland rices were higher plant height, longer panicle, larger roots volume, narrower leaves, higher evapotranspiration, faster flowering phase, greener leaves, higher number of leaves and tillers, heavier dry matter, higher number of grains, heavier 100 grain weight and dry weight of grains. The fraction of available absorbed water at panicle  initiation,  flowering  and  harvesting  were 83.36%, 137.14% and 116.65%, respectively, to obtain dry grains of 3.39 ton ha-1.Keywords: evapotranspiration, water fraction, WUE

Abstract

Seed priming has been widely used to improve seedling vigor of several crops  such as corn, wheat, and rice. Seed priming with zinc to increase seedling tolerance on submergence stress had never been evaluated. The objective of this research was to identify agronomical and physiological characteristics of several rice genotypes during seedling stage at submergence stress following zinc priming treatment. This research used factorial randomized block design with three replications. The first factor was rice genotypes and second factor was zinc solution of ZnSO4.7H2O. Seeds were soaked with Zn solution at different concentrations namely 0, 2.5, dan 5.0 mM respectively for 24 hours. After that the seeds were germinated on soil media in side the plastic box. Fourteen days-old seedling were submerged in water for 5 days and then return to normal condition for recovery. Parameters being observed included seedling dry weight, shoot carbohydrate, and leaves chlorophyl which were measured after 10 days of recovery. Seedling height was measured once a week from 2nd to 4th week. Results showed that intolerant genotypes to submergence stress grew faster but seedling dry weight, shoot carbohydrate and leaves chlorophyll content were lower compared to those tolerant genotypes. Local and national varieties which were not tolerant to submergence stress could be improved by priming treatment with 5.0mM zinc.Keywords: abiotic-stress, seeds- priming

Abstract

ABSTRACTTwelve soybean shade tolerant promising lines and two check varieties, Pangrango and Argomulyo, were evaluated in eight locations covered varying degree of shades. The objective of this study was to assess the effect of genotype x environment interaction on seed yield and yield components, as well as on adaptation and yield stability of the lines  under those environments. The trial, in each location, was arranged in randomized block design repeated four times. The traits evaluated were days of flowering, maturity days, plant height, pod number, 100 seed weight, and seed yield. Light intensity was measured during generative phase, started at plants’ 30 days old,  two week interval. The results showed that genotype x environment interaction significantly affected those evaluated traits. Stability analysis revealed that four lines, i.e., IBK5-173-5-372, IBM22-861-2-22, IBM22-862-4-1, and IBM22-867-4-7 poorly adapted to the environments as indicated by coefficient regressions approximating 1.0 and low yield average. Eight lines, i.e., IBK5-143-3-7, IBK5-147-2-11, IBK5-172-4-36, IBK5-173-5-371, IIj9-299-1-4, IBM22-873-1-13, IBIj11-431-2-20, and AI26-1114-8-28, and the two check varieties, Pangrango and Argomulyo, were unstable. Of the 13 unstable genotypes, two lines, AI26-1114-8-28  and IBM22-873-1-13, gave higher average yield under shade condition (35%-70% shading level), 1.68 t/ha and 1.36 ton ha-1, respectively, than the two check varieties.Keywords: adaptation, Glycine max

Abstract

ABSTRACTUse of shade on the cultivation of  potato in medium altitude is expected to reduce both light intensity and temperature, and therefore is more suitable for potatoes to grow in medium altitude. While the use of growth regulators subtances improving the process of assimilate distribution from the leaves to the tuber. Therefore  use of shade followed by plant growth regulators applications are expected to increase of  growth and yield. The objectives of the experiment were to determine growth and yield of  potato cultivar Atlantik grown  at medium  altitude with different types of shading and  plant growth regulators. The experiment was conducted at an experimental station of the Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang, at an altitude 685 m asl. The experiment was arranged in  a split plot design  consisting of two factors and three replications. The main plots were types of shading (without shading, paranet 45%, UV polyethylene, and corn plant) and the sub plots were combination of plant growth regulators (benzylaminopurine + paclobutrazol), (benzylaminopurine +chloro choline chloride), benzylaminopurine, paclobutrazol, chloro choline chloride).  The results showed that the effect of interaction between shading and plant growth regulator on growth and yield of the potato were not significant. Paranet shade and corn plant shade  increased plant height, leaf area index, tuber weight per plant, yield  per hectar and tuber grade A of potato cultivar Atlantik. Corn plant shading gave potato yield 21.6 ton ha-1 with 64% grade A tuber. Paclobutrazol decreased potato plant  height,  but  increased  number  of  tuber per plant and yielded highest tuber weight of 702.1 per plant (23.3 ton ha-1 ), with 70.9% grade A tuber.    Keywords: Benzylaminopurine, microclimate, paclobutrazol, temperature

Abstract

ABSTRACTThe continuous supply of true-to-type seedling through in vitro technique is very important for cassava (Manihot esculenta Crantz.) as the demand for seedlings is increasing. The research consisted of two experiments and they were conducted from February 2013 to February 2014. The first experiment was in vitro shoot multiplication to evaluate the effect of culture medium and single node position on growth and shoot multiplication of cassava Jame-jame genotype. This experiment was arranged in a randomized complete block design with two factors and four replications. The first factor was culture medium (MS0 and MSB3) and the second factor was single node positions used as explant (basal, middle, and top section of the stem). The result showed that middle section of the stem cultured on MS0 medium had the highest shoot height, number of leaves, and number of nodes. The second experiment was the acclimatization to evaluate the effect of culture period on the success of the acclimatization. This experiment was arranged in a completely randomized design with culture period prior to acclimatization as treatment. The results showed that seedlings from period of 12 and 24 weeks after culture showed higher survival rates (80%) than seedling from period of 36 and 48 weeks after culture (50 and 40%). Culture period prior to acclimatization had no significant effect on plant height and number of leaves.Keywords: BAP, culture period, single node position, shoot multiplication

Abstract

ABSTRACTCharacterization and evaluation of genetic potential of bambara groundnut accessions is very important in order to obtain accessions with high yield potential and early maturity. The objective of this research was to study the phenology, morphology, and yield of four bambara groundnut accessions. This experiment was conducted using a randomized completely block design with one factor i.e. origin of accessions (Bogor and Sukabumi black testa, Sumedang black and brown testa). The results showed that days to seedling emergence of Sumedang brown testa were 9.7 days after sowing (DAS), three other accessions ranged from 8.0 to 8.3 DAS. Days to 75% flowering of Sumedang brown testa was 45.3 days, the other three accessions ranged from 46.0 to 46.7 DAS. Days to pod formation of Bogor and Sumedang accessions with black testa were 49 DAS, Sumedang brown testa at 50 DAS, and Sukabumi accession at 54 DAS. Physiological seed maturity of Bogor and Sukabumi accessions at 112 DAS, Sumedang brown testa at 116 DAS and black testa at 128 DAS. Morphological variation of four bambara groundnut accessions included color of plumule, petiole, seed coat (testa), and leaf shape. Accessions of Sukabumi and Bogor black testa were potential to be developed further because of its showing higher number and weight of pods, and earlier maturity compared to those of Sumedang accessions with black and brown testa.Keywords: early maturity, leaf shape, pod, seedling emergence, testa color

ABSTRACTKenikir (Cosmos caudatus Kunth.) is an Indonesian indigenous vegetable which is potential to be developed. Exploration conducted in Bogor, Sukabumi, Bandung, Bandung Barat, Subang, Garut, Majalengka, Kuningan, and Tasikmalaya had succesfully collected 20 accessions of Cosmos sp. The objectives of this study were  to observe similarity and estimate the yield of Cosmos accessions from West Java. Clusters analysis grouped 20 Cosmos accessions into three clusters. Cluster I consisted of Pendeuy, Saribakti, Karang agung, Sindangbarang, Langensari, Perbawati, Sudajaya girang, Karang tengah, Argalingga, Warnasari, Sukaresmi, Ciwidey, Jalan cagak, Lebaksiuh, Tugu selatan, Ciwarak, Linggarjati and Babakan accessions. Cluster II and III consisted only one accession each which were Ciaruteun and Dramaga, respectively. Seven accessions from different sub cluster were evaluated to estimate the yield. A significant variability was found among the accessions. Results showed that those accessions were significantly different on plant height, stem girth, numbers of primary branches, number of leaf, leaves width, leaves length, days to flowering and yield. The results showed that Dramaga and Ciaruteun acessions were recomended to be developed because of its high yield. Keywords: characterization, cluster analysis, exploration

Abstract

ABSTRACTPhalaenopsis orchid is one of famous genera in Orchidaceae family which have high economic value. Phalaenopsis breeding needs to be developed intensively to fulfill market demand for new varieties. The objective of this study was to obtain the information of  morphological and biochemical diversity of a collection of Phalaenopsis orchid which will be useful for Phalaenopsis breeding. Plant materials used were 10 genotypes of Phalaenopsis with various petal colours of white, yellow, pink, deep pink, purple, or combination of yellow and brown. Morphological diversity of 10 genotypes were analyzed based on qualitative and quantitative characters following UPOV guidance for Phalaenopsis, while biochemical diversity was based on pigment content such as chlorophyl, anthocyanin, and carotene in plant roots, leaves and flower petals. The result of this research showed morphological diversity of 10 genotypes used was relatively high, with similarity of 55%. In that level of similarity, genotypes were grouped into two cluster. Biochemical analysis showed that most of genotypes were different for anthocyanin and carotenoid content for each plant organ. Genotype which showed high content of anthocyanin in leaves was Phal. hybrid ‘PH37’ while high content of carotene in leaves was Phal. hybrid ‘PIROUI. High content of anthocyanin in petals were found in Phal. hybrid ‘PH37’ and Phal. esmeralda, and high content of carotene were in Phal. cornucervi and Phal. cornucervi Red. Root with high anthocyanin content was found in Phal. hybrid ‘PIROU1’. There were significant correlation (0.975) for anthocyanin content between leaves and petals, petals and roots (0.953) on Phal.hybrid ‘PH37’, and between leaves and roots (0.874) on Phal. hybrid ‘PIROU1).Keywords: anthocyanin, carotene, chlorophyll, Phalaenopsis, similarity

Abstract

Induction of polyploid gametes is one of useful plant polyploidization methods. Some of its benefits are to obtain triploid and tetraploid progenies at the same time by cross and self pollination. Previous research showed that some morphological characters which could be the indications of polyploidy plantlets before the analysis of chromosome number. Colchicine treatment on flower bud of diploid Phalaenopsis amabilis was conducted to determine the effect of colchicine on flower bud development, plantlets morphology and growth, and potential of polyploidy induction based on plantlets morphology. Colchicine concentrations in the experiment were 0, 50, 500, 1,000, and 2,000 mg L-1, with three days duration of treatments with aluminium foil wraps on flower buds. The results showed that high colchicine concentrations (2,000 mg L-1) inhibited flowers blooming of treated flower buds. Based on morphological characters, plantlets were classified into normal and putative polyploid plantlets. Putative polyploid plantlets from colchicine with the concentration of 50, 500, and 1,000 mg L-1 were 71.2, 86.4, and 100.0% respectively.Keywords: colchicine concentration, morphological characters, normal plantlets, putative polyploidy, reproductive organ
