Abstract

Abstract: Phalaenopsis orchids are one of the ornamental plants that are very popular with the public because they have attractive flower colors and shapes. One of the obstacles in the success of orchid cultivation is the attack of soft rot disease caused by Dickeya dadantii. Therefore, efforts are needed to find Phalaenopsis clones that are resistant to soft rot disease. This study aims to identify the resistance response of the hybrid orchid genotype Phal. Salu Spot Phal. bellina no. 1102-44. The plant material used was the hybrid orchid Phal. Salu Spot Phal. bellina no. 1102-44 inoculated with Dickeya dadantii bacteria. Identification of the resistance response was carried out through the infection method using the leaf disk technique. The results showed that the clone Phal. Salu Spot Phal. bellina no. 1102-44 was successfully grouped into five resistance classes at 24 JSI (hours after inoculation). A total of three accessions were identified as having resistance to soft rot disease, with two accessions originating from the 22.19 M media treatment (T2-15 and T2-17) and one other accession originating from the 44.39 M media treatment (T4-23).Keywords: orchid, Dickeya dadantii, plant resistance, leaf disk technique Abstrak: Anggrek Phalaenopsis merupakan salah satu tanaman hias yang sangat diminati masyarakat karena memiliki warna dan bentuk bunga yang menarik.

Abstract

Somatic embryogenesis has been recoqnized as one of the process on plant micropropagation  techniques. This process occured through regeneration by direct embryo formation and through an intermediary callus phase. This research was conducted through an intermediary callus phase. The experiment was initiated with callus induction from leaf explant on five modifications of MS medium i.e :1/2MS without plant hormone  (MI-0); ½ MS containing 1mg/L BA + 0.5 mg/L 2.4-D + 1mg/L NAA  (MI-1);1/3 MS containing 2 mg/L  2.4-D (MI-2); ½ MS supplemented with 0.5 mg/L 2.4-D + 0.5 mg/L BAP +0.2 mg/L thidiazuron (MI-3); ½ MS supplemented 2 mg/L thidiazuron and 1 mg/L BAP (MI-4). After the tissues were swollen, the  explants  were  placed on callus proliferation medium  ½ MS supplemented with 0.2 mg/L thidiazuron and 0.5 mg/L 2.4-D (MP). After two months, calli were  regenerated in regeneration medium ½ MS supplemented with 0.4  mg/L BAP and 0.2 mg/L  2.4-D (MR). The results of this research  showed that  MI-1 and MI-3 were the best swelling explant mediums   before the callus  produced in both MP and MR medium. Callus produced was increased in every subculture. However, the level of callii production decreased on the following subculture. Plantlets were regenerated from somatic embryos derived from  callii on MR medium. The results of this study may contribute to our advancement of scientific knowledge achievements tissue culture techniques to support inconventional plant improvement.   Key words:  embryo somatic induction, in vitro, embryogenic callii

Abstract

The objective of this research was to obtain haploid hot pepper plants by inducing gynogenesis with g-ray irradiated pollen for pollination. Fruits resulted from pollination by irradiated pollen was used as the explants of the in vitro culture in solid MS medium containing BAP, IAA and GA3. The resulted plants then cultivated in MS0 medium. The result of the research showed that hot pepper immature embryo could grow and developed into whole plant when the age of this embryo was 9 days after pollination or more. The haploid hot pepper plants can be obtained by pollinating the pistil with 10 Gy irradiated pollen. The MS medium containing BAP 0.3 + IAA 0.2 + GA3 0.5 mg/l and BAP 0.4 + IAA 0.1 + GA3 0.5 mg/l supported well the development of immature embryo into whole plants. The growth of haploid hot pepper plants was slower than that of diploid ones.   Key words:  Hot pepper, haploid plant, gynogenesis, g-ray.

Abstract

These experiments were aimed to obtain optimum medium for micropropagation of Ruscus. There were two experiments consist of in vitro shoots proliferation, shoot elongation and rooting.  The experiment of shoot proliferation performed by inducing adventitious shoots from explant in the Murashige and Skoog (1962)(MS) basal medium supplemented with combination of plant growth regulators BAP (0.0, 0.5, 1.0, 2.0, 4.0 and 6.0 mg/l) and IAA (0.0, 0.1, 0.2 and 0.4 mg/l). The elongation and rooting of plantlets were induced in the different concentration of the MS basal medium (0.5, 1.0 and 2.0 strength) combined with IBA (0.0, 1.0, 2.0, 3.0 and 4.0 mg/l).  Both experiments were arranged as completely randomized design with 15 replications. Adventitious shoots were produced in all medium supplemented with BAP with or without IAA. However MS medium supplemented with BAP 1 mg/l or 2 mg/l combined with IAA 0.2 mg/l were the best.  The number of adventitious shoots in these medium were 9.2 and 9.4 shoots after 8 weeks cultured respectively.  Increasing concentration of BAP more than 4 mg/l decreased number and size of adventitious shoots.  The plantlets produced in the proliferation medium were then transferring to the next treatments for elongation and rooting.  The best medium for elongation and rooting were medium with half strength of MS with or without IBA. Acclimatization conducted by transferring the rooted plantlets on the medium containing sterilized soil and rice husk charcoal (1:1).  After 4 weeks acclimatization, 60-100 percent of plantlets were survived and growth, depend on treatments.   Key words: Acclimatization, adventitious shoot, micropropagation, rooting, Ruscus hypophyllum L.

Abstract

At least ten years needed to abtain new potato cultivar through sexual hybridization, somatic hybridization or through genetic transformation, To short cut this process, Laboratory of Biotechnology, Department of Agronomy, IPB employed a strategy so called single seed in vitro clonal decent ( SSICD) by usings elected parental lines for TPS (True Potato Seed) production. This breeding consist of in vitro pre evaluation for resistance wilt, fusarium wilt, black leg, rot knot nematode and maturity. Using the same number of bacterial cell / (109 cell/ml), there were positive correlation between in vitro test for disease resistance through dripping test or dripping test with greenhouse test through direct inoculation of Ralstonia solanancearum. Resistant clones to fusarium wilt and verticillium were also resistant to bacterial wilt. In vitro tuberization could be use to evaluate maturity of potato cultivar.   Key words: Potato, SSICD

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.
