The objective of this research was to know the effect of compound fertilizer as nutrient source for hydroponics tomatoes. This experiment was conducted from Mei to September 2002, at Cikabayan Experiment Station of The Faculty of Agriculture, Bogor Agriculture Institut (IPB). The compound fertilizers used were Grow More, Gandapan, Hyponex, and Joro AB mix as control. Experimental design used was Randomized Block Design with three replications. The results of this experiment indicated that Joro and Gandapan have the greatest effect for vegetatif phase. There was no significant difference between control (Joro) and the treatments (Grow More, Gandapan, and Hyponex) in number of flower, fruit set, fruit weight, and bad fruit weight, fruit quality, percent total solid. This indicated that the fertilizers could be used as nutrient source for tomato cultured in hydroponics. Key words : Hydroponic, Multi fertilizer, Vegetatif, Generative phase.

Four kinds of antibiotics were examined, viz. streptomycin (SM) and gentamicin (GM) as bactericidal antibiotica and tetracycline (TC) and spectinomycin (SE) as bacteriostatical antibiotics. Kyoho an Pione (tetraploid hybris cultivars) were used as the plant materials. Among the four antibiotics, SM and SE were effective to induce seedlessness in Muscat of Alexandria (MOA) and less effective for Kyoho and Pione. The seedless induction effect of SM and SE seemed not to be affected by their mode of action. Using the four cultivars, Kyoho, Pione, MOA, and Neo Muscat (NM), either SM or SE most effective to induce seedlessness when applied 3 days before full bloom. The ineffectiveness of antibiotics for Kyoho and Pione was indicated by the higher percentage of empty-seeded berries in these cultivars compared to MOA and Nm. Since there was no normal seed in the antibiotic-treated berries, this phenomenon indicated that the outer parts of the tetraploid ovules were more resistant to antibiotic treatments than those of diploid ovules.

The objective of the experiment was to investigate the physical and chemical characteristics of three stadia of maturity based on a range of peel color from green to yellow or based on percentage of the yellow area of fruit peel (stadium 1 = 25-49 % yellow, stadium 2 = 50-74 % yellow, and stadium 3 = above 75 % yellow) on six genotypes of papaya. Each genotype exhibited different days to maturity for each stadium. The fruits of stadium 1, 2 and 3 for IPB 1 were picked at 130, 135, and 140 days after anthesis (DAA); IPB 10A at 160, 165, and 170 DAA; IPB 1 x PB 174 at 135, 140 and 145 DAA; while PB 174, IPB 1 x IPB 10A and IPB 10A x PB 174 were picked at 140, 145 and 150 DAA, respectively. The results indicated that peel firmness was affected by maturity stage on female fruit of IPB 10A. Maturity stage affected chemical characteristics of papaya included total soluble solids (TSS) content (IPB 10A, female fruit of PB 174, female fruit of IPB 1 x IPB 10A, and female fruit of IPB 1 x PB 174), vitamin C content (hermaphrodite fruit of 10 A, female fruit of IPB 1 x IPB 10A) and juice pH (hermaphrodite fruit of IPB 1). IPB 1 genotype can be harvested at all stadia of maturity stage. Hermaphrodite and female fruit of IPB 10 A, female fruit of PB 174, female fruit of IPB 1 x IPB 10A and female fruit of IPB 1 x PB 174 genotype would be better harvested at stadium 3 of maturity stage.

A study was conducted to determine the variation and relationships among papaya genotypes based on morphological and fruit characteristics in order to produce high quality papaya fruits. Fruit characterization study is very useful for genotype improvement and genotype classiﬁ cation of papaya. In this study the morphological characters of 36 genotypes were analyzed to determine their phenotypic variabilities. The relationships between genotypes based on all of the morphological and fruit characteristics were tested by subjecting the data to multivariate principal component analysis and to cluster analysis. Based on the dendrogram generated from vegetative and generative characters, the 36 genotypes could be grouped into 11 clusters on a threshold of 1.6 and formed 6 clusters on a threshold of 1.8. The dendrogram was able to explain the close relationship between IPB 5 x IPB 1 and IPB 5 x IPB 4, IPB 2 and IPB 7, IPB 1 and IPB 3 genotype. The scattered diagram of generative variable divided the papaya genotypes into three groups based on fruit sizes i.e small group (IPB 1, IPB 3, IPB 4, IPB 3 x IPB 4, IPB 1 x IPB 9), medium group (IPB 5, IPB 7, IPB 8, IPB 9) and big group (IPB 2, IPB 10). The IPB 1, IPB 3 and IPB 4 were different from IPB 2 in fruit shapes, petal length of male ﬂ owers, inﬂ orescence size and fruit length. The hybrid plants obtained from crossings with IPB 10 were different from the other genotypes in the colours of female-, hermaphrodite-, and male ﬂ ower-lobes. Subsequently the scatter diagrams also revealed that several genotypes i.e. IPB 2 x IPB 6, IPB 1 x IPB 5, IPB 1 x IPB 9, IPB 5 x IPB 1 and IPB 5 x IPB 2 had superior characters ideotype similar to IPB 1, IPB 3 and IPB 8 genotypes.

ABSTRACTThe improvement of Mangifera indica L. by conventional breeding approaches has been confounded by the long generation cycle, low fruit set, single seed per fruit and high degree of cross pollination. Biotechnology complements conventional breeding and expedite the mango improvement programs. Endosperm culture is a direct method to produce triploid plants. This study aimed to obtain embryo from endosperm culture. The system of secondary somatic embriogenesis in mango described here represents a source of embryogenic material may be used for mass propagation and genetic manipulation of this crop. The method consisted of induction, proliferation, maturation, germination, and histological analysis of the obtaimed embryos. A protocol for plantlet regeneration was developed for Gedong Gincu mango clone 289 through secondary somatic embryogenesis. Primary somatic embryos (proembryo and cotyledonary embryos) were cultured in induction medium to induce the secondary somatic embryos. The best proliferation rate was 0.22 in medium with 1 g L-1 Poly Vinyl Pyrrolidone (PVP) for multiplication of secondary somatic embryos. Maturation of inoculum derived from the proliferation medium supplemented with 2 g L-1 of activated charcoal on medium containing 0.4 mg L-1 BAP provides the average 2.39 embryo formation of cotyledonari phase. The highest germination frequency (20%) was obtained in media with GA3 1.5 mg L-1.Keywords: endosperm, Gedong Gincu, Mangifera indica L, secondary endospermic embrio

The purpose of the research was to examine the pollen germination process and growth rate of pollen tubes of papaya. Pollen tube growth of nine genotypes of papaya (IPB 1, IPB 2, IPB 3, IPB 4, IPB 5, IPB 7, IPB 8, IPB 9, and IPB 10) was investigated in this experiment in order to study their pollen germination rate and pollen viability. The fresh pollen were excised from the fl owers of papaya grown at Tajur Field Station of Research Center for Tropical Fruit, Bogor Agricultural University (IPB), Bogor. The extracted pollen was cultured aseptically on the Brewbaker and Kwack medium (pH 7.3) at ambient temperature of 26-28 °C. Pollen germination and pollen tube growth was observed under optical microscope with 100 and 400 magnifi cation. Papaya pollen viability was not associated with size-based categories of papaya fruits. IPB 4 had the longest pollen tube at fi rst 30 minutes after germination (115.5 µm), whereas IPB 10 had the shortest (99.5 µm). The distance from stigma to ovary in hermaphrodite fl owers varies with genotypes, ranging from 7.38 to 13.44 mm. Average length of pollen tube within four hours of germination for small papaya fruit category (IPB 1, IPB 3, and IPB 4) was 1,030.67 ± 19.14 μm, while the distance between stigma and ovary was short (14.85 ± 2.19 mm) so that the expected of fertilization process occurred sooner. At the end of the experiment (four hours after germination), IPB 1 genotype had the longest pollen tube (1,052 µm) while IPB 9 genotype (913 µm) had the shortest pollen tube. Genotype with the highest percentage of germination at the end experiment was IPB 2 (65.65%), whereas the lowest was IPB 7 (42.56%).

Black cumin (Nigella sativa L.) is an introduced medicinal plant therefore requires investigations to establish recommended cultivation procedure in tropical areas. Black cumin seeds contain a various bioactive compounds not only for culinary but also for medicinal purposes. This study was conducted to investigate the effect of nitrogen rates and shade levels on growth of Black cumin. The activity was carried out in Pasir Sarongge experimental station, Cianjur, West Java (1,117 masl). The research was arranged in nested design with three replications. Nitrogen rates was nested within shading levels. The shading levels consist of 0%, 25%, 50%, and 75% which resulted in light intensity of 27,800, 17,400, 11,900, and 1,600 lux respectively. The Nitrogen rates consisted 0, 60, 120, and 180 kg ha-1. The results showed that shading up to 50% did not affect plant growth and did not reduce seed production. However, shading up to 75% prolong the vegetative period, decreased leaf thickness and plant dry weight. The higher the shading level up to 50%, the higher the plant height, leaf area, number of leaves and number of flower, but not number of branche. Nitrogen fertilizer 60 kg ha-1 increased number of blooming flower and number of capsule set.
