Abstract

Tacca chantrieri is a perennial plant belongs to Taccaceae family that has the potential to be marketed as an ornamental plant due to its unique shape and dark color inflorescence. To date, very limited publication on T. chantrieri are available. The aim of this research was to examine plant growth pattern and flower phenology of T. chantrieri from West Borneo, Indonesia, and from Queensland, Australia in relation to their potential development as ornamental pot plants. The study was extended to examine T. chantrieri seed morphology with an inclusion of an accession from Thailand.  The field experiment was conducted at the Leuwikopo experimental station in Darmaga, Bogor, Indonesia. Seed morphology examination was conducted at the Histology Laboratory of Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University. T. chantrieri from West Borneo blooms six times a year whereas the Queensland accession twice a year. West Borneo accession had smaller bractea, fewer numbers of flowers per inflorescence and shorter flower stalk than Queensland accession. In addition, T. chantrieri Queensland grew faster than Borneo with the one leaf formed every two to three weeks, whereas it was at least four weeks in the Borneo accession. Both accessions were susceptible to leaf brown spot disease caused by Cercospora taccae. T. chantrieri Queensland seeds are oval dark brown, whereas West Borneo and Thailand accessions were shaped like kidneys (reniform) with a lighter brown color. This study demonstrated that there is great diversity in T. chantrieri including plant morphology, seed shape and color, which are important for species identification and for development of T. chantrieri as ornamental pot plant.

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

The selection of Jatropha curcasfor drought tolerance is one of the key points prior to growing the species extensively on marginal lands. The objective of this study was to determine drought tolerant genotypes based on morphological and physiological characters. The research consisted of two experiments. The first experiment was aimed at determining the moisture content of the media to generate drought stress. The experiment was arranged in a split-plot design with moisture content as the main plot and genotypes as sub-plot. Four level of moisture contents were tested, i.e. 22-23%, 27-28%, 32-33%, and 37-38%. The genotypes tested (9) were Dompu-1, Gunung Tambora, Bima (representing genotypes from dry areas); Aceh Besar, IP-2P, Komering (representing genotypes from wet areas); and IP-1M, Papua, Yogyakarta (representing genotypes from moderately dry areas). The result showed that 22-23% moisture content of the media was suitable for drought tolerance test in Jatropha curcas. The second experiment was screening of genotypes using the suitable media moisture content from first experiment. Twenty three genotypes were screened for drought tolerance under 22-23% media moisture content. The result show that Dompu-2, Indralaya and China were tolerant to drought; Sukabumi-1, Sukabumi-2, Pidi, Lahat, Kupang, Lampung-2, Lampung-3, Sumba, IP-2M, and IP-2A genotypes were moderately tolerant; Curup, Bogor-1, Bogor-2, Bogor-3, Pontianak, Pagar Alam, Palembang, Saweli, Jeneponto, and Medan genotypes were sensitive to drought. Plant height, leaf water content, leaf area and percentage of plant survival can be used as indicators of drought tolerance for seedling selection using a non-destructive method.Keywords: drought tolerance, genotypes, Jatropha curcas, screening

Abstract

Production of maize hybrid seed is hindered by relatively poor production by the male line pollen; short live of the pollen which was ascribed to desiccation and dehydration sensitive and flowering asynchrony between male and female lines. The aims of this study were to enhance production and viability of male line pollen and also to determine the suitable storage condition for maintaining pollen viability in order to be used for production of hybrid seed. The research consisted of two experiments. The first experiment was arranged in split plot randomized block design with NPK dosages as main plot (0, 300, 600, 900 kg ha-1) and application of boron as sub-plot (0, 1.5, 3, 4.5, 6 kg ha-1), replicated three times. The second experiment used randomized block design with two factors, i.e. storage temperature (-196 oC and -20 oC) and storage period (0, 1, 2, 3, 4 weeks). The result showed that NPK 900 kg ha-1 increased the number of spike per tassel from 9.3 to 10.7. Application of NPK 600 kg ha-1 or boron 1.5 kg ha-1 improved pollen viability. Combination of NPK 900 kg ha-1 and boron 6 kg ha-1 resulted in the highest pollen viability of 95.3%. Pollen after being stored for four weeks either in -196 ºC or -20 ºC was possible to be used for seed production with 20% seed set.Keywords: boron, freezer, liquid nitrogen, NPK dosage, pollen viability

Abstract

Srikaya’s high quality seeds are needed to support development of srikaya. This study aimed to determine the level of maturity and position of the seeds in the fruit in order to get quality seeds and get the best treatment to improve seedling performance through the use of rhizobacteria and CaCO3. The first experiment used a two-factor completely randomized design (CRD), with the first factor of the color of the exocarp of the fruit and the second factor of the position of the seed in the fruit. The second experiment used CRD with rhizobacteria, CaCO3, and a combination of both as a single factor. The first count time was observed for germination at 36 days after planting (DAP) and the final count was at 56 DAP. The best seed quality was obtained from the yellow exocarp color based on seed dry weight, germination, vigor index, normal germination dry weight, and seed growth speed. The highest seed growth vigor was obtained from fruit with yellow exocarp color from the tip and base of the fruit. CaCO3 treatment affected root elongation, leaf width, stem diameter, and leaf length. Application CaCO3 gives the best effect on seedling growth followed by Pseudomonas + Actimomycetes + CaCO3 treatment. Keywords: Annona squamosa, rootstock, final count, vigor index, rhizobacteria

Abstract

The study was aimed to determine flower initiation, floral morphology and to observe the stages of flowering and fruit development of mindi (Melia azedarch L) within a population for one period of time 2008–2009. The methods used were observing directly over the trees and some vegetatives and generatives buds were sampled for dissecting. The observation revealed that the inflorescence type of mindi was panicle, located at the end of a branch. The number of flower varied among inflorescences, ranged between 30–80 that bloomed simultaneously. The flower was hermaphroditic with position of anther was closed to stigma that selfing might be happened. Usually, the ovary contained 5 ovules that developed into seeds. Reproductive cycle was proceeded for 6–7 months within the year, first observation commenced from flower initiation that occur in August, generative buds to flower burst in September–October. Early fruits were formed in October–November and fruits reached physiological-maturity in January–February. Reproductive success was 34%, indicated that the rate of fertilized ovules proportion to be potencially viable seeds were relatively low.

Abstract

Penelitian ini bertujuan mempelajari pengaruh penurunan kadar air selama pengeringan dengan daya berkecambah serbuk sari mentimun KE014 dan kemampuannya dalam produksi benih hibrida. Percobaan pertama dan kedua, serbuk sari KE014 dikeringkan selama 8, 16, dan 24 jam dalam MgCl2, setelah itu disimpan selama 56 hari dalam ultrafreezer. Daya berkecambah diamati selama pengeringan dan penyimpanan. Pada percobaan tiga, serbuk sari KE014 di penyimpanan, digunakan dalam penyerbukan untuk produksi benih hibrida. Hasil menunjukkan, pengeringan serbuk sari selama delapan jam menurunkan kadar air secara nyata dari 12.05% menjadi 6.71%, sedangkan daya berkecambah meningkat dari 10.16% menjadi 25.60%. Pengeringan lebih lama tidak menurunkan kadar air secara signifikan. Pengeringan selama 8 jam mempertahankan daya berkecambah serbuk sari selama 56 hari penyimpanan. Pengeringan serbuk sari KE014 meningkatkan kemampuannya dalam pembentukan buah dan biji, tetapi tidak untuk daya berkecambah dan bobot 1000 butir benih. Oleh karena itu, serbuk sari KE014 perlu dikeringkan minimum selama 8 jam setelah panen untuk dapat disimpan dan digunakan dalam produksi benih hibrida.

Abstract

Sampai saat ini, belum ada media yang menunjukkan korelasi daya berkecambah serbuk sari dengan produksi dan mutu benih. Oleh karena itu, peneltian ini bertujuan untuk menentukan  media pengujian serbuk sari in vitro yang terbaik untuk cabai dan mempelajari korelasi daya berkecambah serbuk sari cabai secara in vitro dengan produksi dan mutu benih. Penelitian ini terdiri dari dua percobaan. Pertama, mencari media yang sesuai dengan daya berkecambah serbuk sari CB 005 dan CR 002. Kedua, mempelajari korelasi daya berkecambah serbuk sari pada media yang terpilih dengan produksi dan mutu benih. Hasilnya, PGM F menunjukkan nilai daya berkecambah serbuk sari yang konsisten lebih tinggi dari pada media yang lain, sehingga PGM F digunakan sebagai media dasar dalam percobaan modifikasi media. Media yang digunakan untuk pengujian serbuk sari CB 005 dan CR 002 yaitu PGM 1 dan PGM 4 (PGM F). Secara umum, daya berkecambah CB 005 tidak berbeda menggunakan PGM 1 dan PGM 4. PGM 1 memberikan nilai rata-rata daya berkecambah serbuk sari CR 002 yang lebih tinggi dari pada PGM 4. Pengujian daya berkecambah serbuk sari CB 005 dengan media PGM 1, PGM 4 (PGM F),  dan Ewid 1 tidak berkorelasi  dengan pembentukan buah, pembentukan biji, daya berkecambah benih, dan bobot 1000 butir.

Abstract

The low production of true seed of shallot (TSS) is mostly caused by a low flowering rate. The research was aimed to increase the flowering rate and seed yield in lowland (240 masl) and highlands (1250 masl) by vernalization and submersion of the seed bulbs in GA3 before planting. The research was arranged in a completely randomized block design with 2 factors and replicated four times. The first factor was vernalization, i.e. without and with vernalization at 10±2°C for 30 days, and the second factor was the submersion of the seed bulbs following vernalization in GA3 at the concentrations of 0, 100, and 200 ppm for 1 h. Parameters measured were time of 50% flowering (days after planting), percentage of flowering plants, number of umbel per plant, number of floret per umbel, fruitset, seed weight per umbel and per plant, as well as the percentage of seed germination. The result suggested that when production of TSS of var. Bima is to be carried out in the lowland then the seed bulbs had to be vernalized at 10±2°C for 30 days which will increase the flowering percentage and seed yield. If the production of TSS is to be carried out in the highland then vernalization at 10±2°C for 30 days will increase the flowering percentage and seed yield. However, if for any reason vernalization is impossible to proceed then the submersion of the seed bulbs in 100 ppm GA3 for 1 h was sufficient to increase the flowering percentage and seed yield. The produced seeds (TSS) either in the low as well as in the highlands had high germination percentages. Keywords: germination, highland, lowland, umbel, true seed of shallot
