Abstract

Studies in transgenic sugarcane (Saccharum officinarum L.) demonstrated that sucrose transporter (SUT) genes were essential in sucrose translocations. Sucrose transporter gene isolated from sugarcane were designated as SoSUT1 and SoSOSUT2 respectively as encode protein of 518 and 747 amino acids. The genes were constructed into plasmid pYES2 for SoSUT1, and pYX112 for SoSOSUT2. cDNA SoSOSUT2 had also constructed into plasmid pBIN-At-GFP which was possible to trace the gene inserted. The constructed plasmid was transformed into yeast (Saccharomyces cerevisiae) and grown in minimal medium (SD–urasil) as selection medium. The transformed colony was confirmed using PCR. The functional expression was studied by growing yeast in YPD medium with 2% Sucrose, then the sucrose uptake was measured in number interval time using resorcinol method. The result showed that yeast INVSc1-pYES2-SoSUT1 and BF264- pYX112-SoSOSUT2 had higher ability in sucrose transport compared to the control-INVSc1 for SoSUT1 and control-BF264 for SoUT2. Moreover, the result showed that SoSUT1 had higher ability to transport sucrose than SoSOSUT2. Confocal microscope observation showed that transformation gene SoSOSUT2 was successful, which was indicated by green exposure of GFP protein.Keyword: sugarcane, sucrose transporter, yeast

Abstract

The research was conducted to study the agronomical characters as the resistance attributes of twenty soybean varieties to Nezara viridula. The results showed that the twenty soybean varieties had a different response to stink bug infestation. Gepak Kuning, Seulawah, and Sinabung were resistant to stink bug, while Argomulyo were highly susceptible, and Grobogan and Malabar were susceptible. Besides resistance to stink bug, Sinabung also had the highest seed yield (2.95 t/ha). The seed yield of Gepak Kuning and Seulawah were not high, i.e. 2.20 and 1.82 t/ha respectively. The three highly susceptible or susceptible varieties also showed the lowest seed yield, i.e. 0.68 t/ha (Argomulyo), 0.42 t/ha (Grobogan) and 0.99 t/ha (Malabar). The negative correlation was shown between resistance to pest with days to maturity, duration of the reproductive phase, the number of unfilled pods, and weight of 100 seeds. Seed yield also had a negative correlation with duration of reproductive phase and weight of 100 seeds. It indicated that varieties with short duration of reproductive phase and small seed size were preferred by Nezara viridula as food sources. Therefore, these two characters can be used to determine the soybean resistance to Nezara viridula.

Abstract

Foxtail millet is relatively tolerant to salinity stress and thus can be grown in salinity affected areas. This study was conducted to identify anatomical changes in the roots of foxtail millet genotypes with different tolerance level to salt stress. Four foxtail millet genotypes, namely ICERI-5 and ICERI-6 (salt tolerant) and ICERI-4 and ICERI-10 (salt sensitive), were grown hydroponically for 1 week prior to 60 and 120 mM salt stress treatments. Root anatomical changes were observed on the fifth day after treatments. The results showed that salt stress significantly induced some anatomical changes in the roots of foxtail millet, i.e. increased epidermis and cortex thickness, increased root diameter, and increased the number of root hairs. The increase in epidermis thickness, root diameter and the number of root hairs due to the salt application were more pronounced in the sensitive genotypes. Number of protoxylem in the tolerant genotypes were significantly increased due to salt stress, however salinity significantly decreased the number of protoxylem in the sensitive genotypes. The different anatomical changes under salt stress between the tolerant- and sensitive genotypes indicated that some anatomical attributes of the roots might determine the salt tolerance level of foxtail millet.

Abstract

The research aims to know the life cycle, feeding and mating behavior of predatory beetle S.  gilvifrons, and was conducted at entomology laboratory of Assessment Institute for agri-cultural technology Malang - East Java. The treatments involved feeding behavior and capacity of the various instars and imago of S. gilvifrons. The number of mites consumed within 24 hours by each stage of beetle was also recorded. The average voracity of five individual predators for each instar was determined.  The result showed that average life cycle of S.  gilvifrons feed on E. orientalis was 4.11 + 0.78; 8 + 1.10; 3.83 + 0.41, respectively for egg, larva and pupa.  The predator caught the preys from the front side, then chewed and sucked the body contents of adult preys or consumed the whole egg.  The feeding capacity was greater in egg-laying than that in non egg-laying females and males.  The smallest size of the cage (1.5 cm diameter x 5 cm long) and clear weather were the most preferred situation for S.  gilvifrons mating, which  usually occurs on the upper leaf surface.  The male positioned itself over the female body and extended its aedeagus to reach the female.    Keywords: Life-history, Stethorus gilvifrons, phytophagous mites

Abstract

Areal cultivation of sugarcane in Indonesia is expanded to soil with high salt content. There is an urgent need to find an appropriate soil amendment fertilizer to minimize negative effect of saline soil on sugarcane growth. The objective of the research was to determine the effect of vermicompost and nitrogen on N, K and Na uptakes and growth of sugarcane grown in saline soil. The treatments consisted of three rates of vermicompost (equivalent to 0, 10, 20 t/ha) and three rates of nitrogen fertilizer (equivalent to 50, 75 and 100 kg N/ha). Nine combinations of treatments were arranged in randomized block design with four replicates. Sugarcane commercial variety of ‘Bululawang (BL)’ was planted for 4 months in soil with Electrical Conductivity (EC) of 4.12 dS/m. Results showed that interaction between vermicompost and nitrogen fertilizer rate increased N, K uptakes and growth of sugarcane in saline soil. Addition amount of vermicompost and nitrogen reduced soil EC and Na/K ratio uptake of sugarcane. In this study, addition of 20 t vermicompost together with 50 kg N/ha induced sugarcane production with the highest biomass during 4 month planted in saline soil.

Abstract

The physiological response of cocoa plants under VSD infections is still limited because there is no method in artificial inoculation since Oncobasidium theobromae was reported as parasitic obligates. The investigation of correlation between cocoa responses and VSD attack becomes important information to figure out the effect of decreased productivity as the consequences of the physiological damages. The objective of this research was to describe the pathogen infection and the symptom of VSD through fungal staining method and to asses the changes of some physiological aspects (chlorophyll and gass exchange character) under VSD pathogen infection. This study was conducted in Kaliwining experimental station, ICCRI, Jember, East Java, Indonesia. The result of the study indicated that late infection stage caused chlorophyll degradation, decreasing transpiration rate, and increasing temperature in both tolerant clone (Scavina 6) and susceptible clone (TSH 858). The rate of photosynthesis, stomatal conductance, and concentration of CO2 in susceptible clone (TSH 858) showed a drastic decrease when infected by VSD pathogen than that of in healthy plants. In resistant clone (Scavina 6), photosynthesis rate, stomatal conductance, and concentration of CO2 showed no significant decrease when infected by VSD pathogen compared to that non-infected condition.

Abstract

Priming is a process that controls the process of hydration of seeds for the ongoing metabolic processes before germination.  Research on   priming   was conducted  at  ICERI seed laboratory  from May to September 2009  to evaluate the  effect of different priming methods on  wheat seed vigor. Physical properties and chemical composition of seed were evaluated before seeds were treated. The priming treatment were conducted by soaking 250 g of seed in  500 mL of  solution for hydropriming and halopriming.  Two seed lots of Nias and Dewata variety were subjected to heated and unheated  distilled water for 12hours and subjected  to  KCl and CaCl2  at 10, 20, and 30 ppm and unprimed seed. The experiment were arranged in completely randomized design,  replicated thrice.  Vigor evaluation by observed  seed germination, simultaneity growth, germination rate, seedling dry weight, electric conductivity of seed  leakage and  length of primary root.   The results showed that highest  germination,  simultaneity growth, seedling dry weight, and length of primary root,  were priming treatment    with  KCl  30 ppm  and CaCl2  20 and 30 ppm.  Priming  with distilled  water for 12 hours gave  higher  germination percentage  and  simultaneity growth.   Keywords : priming, wheat, seed, vigor

Abstract

A laboratory experiment was conducted to elucidate roles of Gliricidia sepium and Tithonia diversifolia composts and their extracted humic and fulvic acids on aluminum concentration in an Ultisol. Those composts and humic and fulvic acids extracted from them mixed with soil were arranged in a complete randomized design with three replicates, and incubated for 90 days. Al concentration and pH of the soil were measured at 0, 3, 10, 20, 30, 45, 60, 75 and 90 days after incubation. Results of the study showed that the highest decrease in exchangeable Al concentration (90.5%) was observed for Tithonia fulvic acid treatment during 90 days, followed by Tithonia compost (88.4%), Gliricidia fulvic acid (82.3%), Gliricida compost (82.2%), Tithonia humic acid (75.66%), and Gliricidia humic acid (73.46%) treatments, whereas control only decreased exchangeable Al concentration by 0.9%. The rate of change in exchangeable Al concentration was fast for the first 45 days, but it then slowed down for the second 45 days (45-90 days). This was particularly observed with organic acid treatments, whereas compost treatment still showed a subsequent decrease. Patterns of Al chelate and pH were very similar to that of exchangeable Al. It was thus concluded that roles of humic and fulvic acids in reducing exchangeable Al was only short term, whereas compost played roles in the long term.Keywords: Ultisol, aluminium, humic acid, fulvic acid, gliricidia sepium, tithonia diversifolia
