Abstract

One of the definite successful of rice breeding programs for increasing yield and tolerance to environmental stress condition is selection method. Selection method will be effectively if it is supported by a perfect knowledge of genetics character inheritance. The objectives of this study is to investigate the information of inheritance pattern adapted of rice towards low temperature stress condition. The experiment was conducted in both Sesean rural area, Toraja regency, South Sulawesi on 1500 m above sea levels, an mean temperature 15 o C, type of soil is Podzolic and at Bogor Agriculture Institute. This experiment is done in January 2006 until July 2007. The result showed that tolerance parental grew well and higher yield than sensitive parental. There were no significant differences between F1 and F1 reciprocal for all characters. Tolerance parental is more superior than sensitive parental in all characters have been tested. Mean of F1 generation is in between tolerance parental and sensitive parental. BCP1 has spheres wider than parentals and F1 generation, but BCP2 smaller than parentals and F1 generation. F2 generation is spheres wider than the average of both parentals. The m [d] [h] genetic model is the most suitable for all characters. Except, date of flowering and weight of filled rice where appropriate models is m [d] [h] [l]. Broad sense and narrow sense heritability is range between low to high. Based on the degree of dominant, additive effect is higher than dominant effect. The negative F value reached on date of flowering and fur lenght; and others characters, F value is positive.

Abstract

Molucca, in general and especially Ambon has ground nut fields with low productivity compared to national yield of ground nut. Brunizem has low levels of K and P nutrients. These conditions were interesting to be investigated. The research took place in a plastic house for two months in Halong village, sub district Baguala. The research was done in a Completely Randomized Design with 2 Factors. The first factor was three levels of K fertilizer, ie K0 (no K fertilizer application), K1 ( 0.5 g KCl/pot) and K2 ( 1.0 g KCl/pot). The second factor was three levels of P fertilizers, ie P0 (no P fertilizer application), P1 (0.6 g SP-36/pot), and P2 (1.2 g SP-36/pot). The aim of the research was to investigate the availability and sorption of potassium, growth and dryweight-of ground nut (Arachis hypogaea L.) seed due to the application of KCl and SP-36 fertilizers on Brunizem. The results of this research showed a high significant effect of potassium fertilizer treatment on soil-pH, availibility and sorption of K, plant height, stem diameter, and dryseed weight of ground nut. Treatment g P fertilizer has a significant effect on soil pH, available K, plant height, and dry weight of seed. The interaction of K and P fertilizers had no significant effect on K availability and sorption of K. K availability of 0.26 me/100 g and 4.95% of plant-K was attained at the treatment of 1.0 g KCl/pot. The high dry yield of ground nut (17.35 g/pot) was achieved at dose of 1.0 g KCl/pot, meanwhile dose of 1.2 g SP-36/pot gave the highest seed-dry yield of ground nut

Abstract

Several bacterial pathogens can cause diseases of potato. Ralstonia solanacearum and Erwinia carotovora are those of the world’s most important diseases of potato, especially in tropical climates. This experiment was aimed to obtain putative potato cultivars having good tolerance to bacterial wilt caused by R. solanacearum and soft rot caused by E. carotovora. Two adopted potato cultivars in Indonesia, cv. Atlantic (2n=4X=48) and cv. Granola (2n=4X=48), were used as parents. The experiment was arranged in a Randomized Complete Design. Test for tolerance was perfomed in vitro using BF15 as susceptible control and Solanum stenotonum as tolerance control. The result showed that there was high diversity of tolerance level to both R. solanacearum and E. carotovora. Some clones showed good tolerance level as compared to cv. Atlantic and cv. Granola, but none showed that as compared to S. stenotonum.

Abstract

The objective of this experiment was to study the influence of post-harvest storage and storage period to seed viability. The research was conducted in the Laboratory of Seed Science and Technology and the green house at Leuwikopo IPB Darmaga, from February until August 2007. The experiment used split-plot design with three replications. The main plot was seven periods of storage: 0, 3, 6, 9, 12, 15, and 18 weeks. The sub plot was the period of post-harvest maturation storage (use the fruits with 30-40% yellow coloured): 0, 2, 4, 6 days post-harvest storage, and control fruits that ripe on the tree (with 80-90% yellow coloured). The control fruits have the best seed viability and vigor. Viability of seed from fruits with 0, 2 and 6 days post-harvest storage was significantly less than that of control. Seed from four days post-harvest storage have same viability as control. Post-harvest storage can improve physiological seed quality on the seed that must be harvested before the time of physiological maturity, especially four days post-harvest storage

Abstract

A field research was conducted to study morpho-ecotype and proximate aspects of Banda nutmeg (Myristica fragrans Houtt.) in three ecotypes: Banda Islands, Ambon Island, and Ceram Island in Maluku. The objectives of the study were to characterize morpho-ecotype of the Banda nutmeg, to investigate the trees productivity across three ecotypes, and to identify the proximate characteristics of the fruit. Ten productive nutmeg sample trees aged ranging 25 to 50 years were chosen for observations. In morphological observation, 21 items were described based on IBPGR procedure, and then subjected to UPGMA cluster analysis. The proximates of nutmeg flesh including edible portion (EP), water content, protein content, fat content, and pectin content were analyzed by AOAC procedure. Morphological and proximate data were analyzed using SAS. Results show that Moluccas ecotypes characterized by hill and mountain has tectonic mountain physiography and karst soils with a slope of 16 to 40%. Ambon and Banda ecotypes are mainly composed of volcanic soils, whilst Luhu has sediment. The climate of Moluccas ecotype is dominated by IIIC type, except Banda Island which has IIB. The morphological traits of the nutmeg are stabile across three ecotypes (similarity index, SI 90%). Productions of fruit, nutmeg, and mace show no difference between the three sites. They are 137.73, 19.27, and 3.07 kg per tree, respectively. All proximate parameters analyzed are not statistically different, except EP. EP of Ambon ecotype is statistically different from that of Ceram but it is similar to Banda ecotype.

Abstract

Latex yield of rubber tree (Hevea brasiliensis Muell. Arg.) is a complex trait influenced by external and internal factors. In this trial, F1 progenies of two populations (crossing PB 260 as high latex yielder x PN as low latex yielder) and their parents were used to study the characteristic of yield components, namely physiology, anatomy and growth characters which influence latex yield. Based on statistic analysis, it showed that latex yield of two populations had high variation among their F1 progenies. The other variables such as girth, bark thickness, number of latex vessel rings, plugging index, sucrose content and inorganic phosphate content also showed high variation. Based on path analysis and stepwise regression, it showed that the number of latex vessel rings and plugging index had bigger direct effect on determining latex yield of A population (PB 260 x PN 7111), while girth and plugging index variables had bigger direct effect on latex yield of C population (PB 260 x PN 7).

Abstract

The objective of this research was to study the morphology and physiology of jatropha leaves and its relation to photosynthesis. Research was conducted using Randomized Complete Block Design with single factor, i.e., leaf ages at the canopy with ten replications. The results showed that jatropha had phyllotaxy 5/13 with angular divergence 1380 . In early growing leaf enlarged sharply and then constant after 9 week, remaining green for 14 weeks. Chlorophyll a, b, and total achieved maximum at 9 week, i.e., 0.45 g/cm2 , 0.19 g/cm2 , and 0.62 g/cm2 , respectively. Photosynthesic rate was maximum at 6 week, i.e., 8.99 µmol/m2 /s, while number of stomata was maximum at 9 week (289.47 mm2 ). This finding implies that leaf number 11 to 13 or age 6 week after emergence could be used as reference for photosynthetic evaluation.

Abstract

The experiment was aimed to investigate the Al-tolerant mechanisms physiology of legume cover crops species related to metabolism NO3 - , NH4 + , and N02 - . The results revealed that an addition of Al had less effect on Al-tolerant species compared to Al-sensitive in term of reduction in NO3 - , NH4 + and N02 - uptake. The reduction in Nitrit of the Al-tolerant species under Al treatment was less than in Al-sensitive species. The results suggested that in tolerant legume cover crops species, the higher level of Al tolerance seems to have emanated from efficient NO3 - metabolism and the higher N02 - to NH4 + .

Abstract

Stevia rebaudiana Bertoni, a sweetener plant, has been cultivated in Indonesia since the early 1980s, but the yield is lower than in other countries. Five selected introduced stevia clones were planted at Megamendung, Bogor, Indonesia (6°39’ S, 106°56’ E, 800 m above sea level) on December 2014 until November 2015 to evaluate their growth and biomass yield. The growth and yield were observed from 6 to 12 months after planting. In addition, stevioside, rebaudioside A (reb A), and total steviol glycoside (TSG) contents of leaves were measured using high performance liquid chromatography (HPLC). At six months after planting, stem diameter was 8-11 mm, plant canopy diameter was 23-30 cm, plant height was 24-35 cm, and plant mortality was less than 5% except for clone BU at 30.7% due to Sclerotium attack. The plants flowered at different times, therefore had different harvest durations, from 4 weeks (clone BM) to 8 weeks (clone BP). The highest leaf yield was clone BM (6.04 ton ha-1 per year), followed by BX (4.91 ton ha-1 per year), and BP (4.38 ton ha-1 per year). From the five clones tested, clone BM was the best for leaf, TSG, and stevioside yields; whereas clone BS and BP were the best for reb A yield. Keywords: rebaudioside A, Stevia rebaudiana, stevioside, total steviol glycoside
