Abstract

A number of Trichosanthes species has been reported as a source of bioactive protein associated with defense mechanisms such as chitinase. Chitinase and peroxidase of crude protein extracted from leaves, roots, in vitro calli and shoots of T. tricuspidata had been analysed. Calli were induced on MS medium containing combinations of 1 µM NAA + 1 µM BA  (K1), 2 µM NAA + 2 µM BA (K2), 3 µM NAA + 3 µM BA (K3), or 4 µM NAA + 4 µM BA (K4). Shoots were cultured in MS with 1 mg/l of BA, while leaves and roots were harvested from six-month old plants grown on the field. Results of the experiment suggested that K1-K4 medium could be used to induce calli although weight of calli from all medium composition  was not significantly different (0.19-0.31 g/explant/4 weeks). Calli from K1 medium had the highest of total crude protein content (3.24 mg/ml). The highest of chitinase activity was found in in vitro shoots (6.51 mM pNP/hour/mg protein) and the highest peroxidase activity was in the plant roots (0.25 ∆ 420/minute/mg protein).   Key words:  in vitro calli, shoots, crude protein, chitinase and peroxidase activities

Abstract

The research was aimed at studying the effects of seed deoperculation treatment and germination substrate to enhance viability of sugar palm seed. This research was conducted from February until August 2006 at Seed Science and Technology Laboratory and Turfgrass area. Randomized block design with 2 factors was used in this research. The first factor consisted of five treatments namely: control, without seed treatment (P0), deoperculation with sand paper precisely on the embryo position (PI), deoperculated seed and heating in the incubator at 40oC for 5 minutes (P2), deoperculated seed and soaking in the potassium nitrate (KNO3 0.5%) for 36 hours (P3) and deoperculated seed, soaking in the potassium nitrate for 36 hours and heating in the incubator at 40oC for 5 minutes (P4). The second factor substrate used for germination consisted of five types, i.e., sand (M1), soil and compost mixed, each in equal (1:1) portions by weight (w/w) (M2), saw dust (M3), cocopeat (M4) and paddy charcoal (M5). The result showed that seed deoperculation gave very significant effect to enhance seed viability. The interaction between seed treatment and substrate significantly influenced on potential growth, germination percentage, speed of germination, the length of embryonic axis and the length of root. The highest potential growth of 96.67% was obtained from deoperculated seed and heating in the incubator at 40oC for five minutes and germinated in sand, whereas highest germination percentage of 88.33% was reached by deoperculated seed and germinated in sand. Sand (M1), cocopeat (M4) and paddy charcoal (M5) were suitable for germination substrate of sugar palm seed.   Key words:  Sugar palm seed, seed viability, deoperculation, cocopeat, paddy charcoal.

Abstract

The objective of this study was to analyze the inheritance pattern of soybean adaptation to shade stress based on leaf morpho-physiological characters. Genetic materials used in this study consisted of 22 plants of low irradiance (LI)-tolerant genotype (Ceneng) and 22 plants of LI-sensitive genotype (Godek); 21 plants of F1 (Ceneng x Godek); and 114 plants of F2 populations (derived from F1). These populations were planted under shading of paranet 50%. The population was arranged in a Randomized Complete Block Design with two replicates. Analysis of inheritance of soybean adaptation involved estimation of heritability (broad sense) and gene action. Results of this study showed that: adaptation of soybean to low light stress based on characters of yield per plant was highly heritable (68% of broad sense) with partial dominant mode of action. Characters of leaf area and specific leaf weight were highly (68% of broad sense) and moderately (48% of broad sense) heritable, respectively, with additive mode of action. Soybean adaptation based on leaf physiological characters (chlorophyll contents) was highly heritable (70% - 86% of broad sense) in epistatic mode of action.   Key words:  Soybean, leaf morpho-physiological character, heritability, gene action

Abstract

The research was aimed to study the response of oil palm seedlings to drought stress and to determine characters which would be useful in selection for drought resistance. This research was conducted at PT Dami Mas Sejahtera field station and SMART Research Institute laboratory Libo, Riau from April to August 2005. The research was arranged in split plot design with two factors in randomized block design. The main plot was soil water content, i.e. 100%FC/field capacity : 24+1%; 75%FC : 18+1%; 50%FC : 12+1%; and 25%FC : 6+1%, whereas the subplot was four genotypes: G1: 635xAP.01, G2: 635x742.316, G3:15x742.316 and G4: 15xAP.01. The result showed that only soil water content as low as 25%FC could significantly inhibit seedling growth, as indicated by reduction of leave water content,  shoot and root dry weight, seedling height, root length and volume; and an increase of water deficit. Soil water content ranging from 50-100% FC did not give any significant effect. Based on the physiological responds, G1 and G3 were relatively more resistant to drought stress than G2 and G4. Leaf water content was the easiest, cheapest, fastest and non-destructive variable to be used for early selection of drought resistant oil palm seedlings.   Key words:  Oil palm, seedling, character for selection, drought resistant

Abstract

Germination and growth at seedling stage are critical phases in plant life cycle, especially for physic nut (Jatropha curcas L.) usually grown in a dry land. Therefore seedling preparation plays an important role in nursery stock production. Position and depth of seed sowing affected the germination process and further seedling growth and development. A Completely Randomized Design with two factors was used in the experiment, i.e., depth of seed sowing (1, 2, 3, 4, and 5 cm) and seed position (seed with micropyle at the bottom, face-down, and layback). The result showed that position and depth of seed sowing affected the germination and early growth and development of seedling. The effect of seed position on growth and development of seedling persisted until the end of the experiment when the seedlings were two months old. Face-down position with 2 - 3 cm depth represented the best position and depth for seedling growth.   Key words:  Early seedling growth, micropyle, face-down position, layback position

Abstract

A study to determine the best alternative substrate paper for testing seed viability in rolled paper method was conducted with 2 experiments. The first experiment studied the physical characteristic of six substrate papers, straw, filter, stencil, CD, HVS and Samson related to seed germination. The second experiment was conducted to identify the best alternative substrate for testing germination of different seeds. High and low viability of rice, maize, peanut, yardlong bean, chick pea and leafy vegetable seeds were tested with the substrate papers arranged in a Randomized  Block Design with three replications. The first experiment showed that CD and Stencil papers had good physical characters for germination substrate. Water absorption of CD and stencil papers were 28.1g and 24.4g per medium unit, lower than Straw paper (46.51 g/medium unit) but significantly higher than the international standard of filter paper  (20.7g/medium unit). In rolled paper test, no significant difference of water holding ability among the papers. Water lost during the 7 day testing were less than 2 g/medium unit for all of the papers. All of the papers including stencil and CD papers were homogenous with low coefficient of variation, less than 5%. The second experiment showed that different data of germination percentages and dry weight of normal seedlings were obtained from the diferrent subtrate papers. As compared to the common substrate straw paper, the stencil paper produced the most similar data, 100% and 91.7% similarities of germination percentage and  dry weight of normal seedlings, respectively, whereas the other papers performed 37.5 - 91.6% and 29.1 - 66.7%.   Key words:  Substrate paper, physical characteristic, seed viability testing.

Abstract

The research aimed at studying the effect of moisture content, package and storage period on mitochondrial inner membrane protein of soybean seed. The research was conducted in the laboratory of Seed Technology and Microbiology of Gadjah Mada University from May 2002 to August 2003. A Randomized Complete Block Design was used in the experiment with three factors and three replications. The first factor was moisture content consisted of three levels, i.e. 8%, 10%, and 12%. The second was three kinds of packages namely polyethylene plastic, wheat and aluminium foil. The third was the storage period, i.e. 0, 1, 2, 3, 4, 5 and 6 months. Data collected were analyzed by analysis of variance and Duncan Multiple Range Test. Regression and correlation analysis were done to study the correlation between germination, vigor and protein content of mitochondria inner membrane. Record was made on protein content of mitochondrial inner membrane and its electrophoresis profile, electrical conductivity, germination and vigor. The result showed that moisture content, packaging and storage period had significant influences on protein content of the mitochondria inner membrane and its electrophoresis profile. Inner membrane protein of mitochondrial had a positive correlation with germination and vigor. It was concluded that moisture content, package and storage period affected inner membrane protein content of mitochondria and its protein electrophoresis profile. The protein content of mitochondrial inner membrane, germination and vigor of soybean seed stored in aluminium foil sack at 8%, 10% and 12% moisture content did not decreased within 6 months. Cell membrane damage affected mitochondrial damage.   Key words:  Soybean seed, mitochondria inner membrane protein
