Abstract

ABSTRACTIn vitro breeding technique of citrus is effective when optimum explant regeneration method is obtained. Low germination frequency and high abnormality were barrier in citrus somatic embryogenesis. This research aimed at optimizing somatic embryogenesis in Tangerine var. Batu 55. This research consisted of 3 experiments. First experiment was maturation of embryogenesis, using Completely Randomized Design (CRD) method. Modified MS+MW was used as basic media added with 500 mg L-1 malt extract (control) and addition of 3 mg L-1 BAP, and 2.5 mg L-1 ABA as treatments. Second experiment was SE (cotyledonary phage) desiccation. Factorial CRD used in two factors. First factor was poly-ethylene-glicol/PEG 8000 (0, 2.5, 5, 7.5 and 10%), while second factor was immersed periods (control, 3, 6, and 9 hours), in desiccant solution (base medium + PEG). Third experiment was studied of plantlet growth and development planlets. Based on CRD 2 factor method, the first factor was PEG concentrations from the second experiment. Second factor were active charcoal treatments (with or without), in basic media. The result showed that 2.5 mg L-1 ABA produced has highest mature somatic embryo (SE). Desiccation for 9 hours, induced the highestt germination frequencies (90.29%). The best growth of plantlets shown in previous experiments immersed desiccant PEG 2.5% for 9 hours, and cultured in basic media with 2 g L-1 of activated charcoal.Keywords: desiccant, embryogenic callus, maturation, PEG 8000, somatic embryo ABSTRAK Pemuliaan tanaman melalui teknik in vitro efektif bila metode regenerasi eksplan optimum telah diperoleh.

Abstract

In vitro selection to increase the citrus resistance to Huanglongbin-HLB diseases, requires theavailability of lime in vitro shoots as a negative control, because it is one type of citrus that is verysusceptible to HLB. In vitro shoots can be obtained from seed germination in vitro with a more controlledenvironment. Shoots derived from in vitro germination can be used as controls when in vitro artificialinoculation by pathogen suspension is performed to select in vitro breeding lines. This study aims to obtainthe best concentration of gibberellins and scarification treatment for in vitro germination of lime.Germination was carried out on citrus seeds that had been sterilized on the surface of the fruit. Scarificationis done by injuring the testa of the seed. Lime seeds with and without scarification treatment were germinated on MS+VMW base media with the addition of GA3 0 mg L-1, 5 mg L-1, 10 mg L-1, and 15 mgL-1. The results showed that the optimal concentration of GA3 to induce lime seed germination was 5 mgL-1. Scarification by wounding the seed testas significantly accelerated lime germination time.

Abstract

Seedless fruit is one of the criteria (necessary) to improve the quality of Simadu tangerine. The most effective method to obtain seedless triploid cultivars is hybridisation between tetraploid and diploid parents. Simadu tangerine is a diploid plant. Tetraploid Simadu tangerine can be obtained with doubling chromosome using colchicines.The aim of this research was to obtain tetraploid Simadu tangerine shoot which would serve as parent to produced seedless Simadu tangerine. Shoot-tips of Simadu tangerine without leaves were treated with colchicines at four different concentrations (0, 0.1, 0.2, and 0.3%) for 3 hours. The results showed that the high concentration of 0.3% reduced survival rate. The colchicine treatments reduced growth of shoot-tip of Simadu Tangerine.The leaves of colchicines treated shoots were thicker than control. Leaves from control (0% colchicine) and 0.1% colchicine treated shoots had 8.67 and 18.25 chloroplast per pair of guard cells. Compared to those of control, leaves with 0.1% colchicine had lower stomatal density, and larger stomatal size. It appeared that 0.1% colchicine treatment resulted in tetraploid Simadu Tangerine Shoot.Keywords:chloroplasts, doubling chromosomes, stomatal size, stomatal density

Abstract

ABSTRACTMandarin Citrus cv. garut is a of local citrus variety with several superiority, but not competitive to imported citrus. Quality improvement have been the subject of citrus breeding programme. The objective of this research was to determine lethal dose 50 (LD50) and putative mutans regenerant selected based on morphological markers. Callus was irradiated at doses of 0, 20, 30, 40, 50, 60, 70, 80, 90 and 100 Gy and regenerated through somatic embryogenesis. The result of radiosensitivity showed that lethal dose 50 (LD50) analyzed by Curve Expert 1.4 software was 75.31 Gy. Observation on callus showed variation on morphology and weight of callus. Callus growth was not inhibited at doses 0-50 Gy but at doses 60-100 Gy callus growth was inhibited. Gamma irradiation also affected the formations of somatic embryos. After six weeks on maturation medium, the highest number of embryo somatic was produced from doses of 20 and 100 Gy and following culture on germination medium, the highest number of planlet was produced from doses of 20 and 40 Gy. Based on morphological characters, the selected regenerants had variability of 0-58%.Keywords: gamma irradiation, germination, lethal dosis 50 (LD50), maturation, somatic embryo

Abstract

The gene that regulates callose could be modified by CRISPR/Cas9 technology. This research aimed to insert the CRISPR/Cas9-CsCS gene into Ponkan orange genome using Agrobacterium tumefaciens. The explants were soaked in a bacterial suspension for 20 minutes and incubated for 2-3 days. In vitro acceleration growth was conducted with a two-factor completely randomized design. The first factor is the type of explant with three levels (nucellar embryo, zygotic embryo, cotyledon node), and the second factor is the type of media with 6 levels (VMW, MT, MSK0, MSK1, MSK2, MSK3). The results showed of all explant types, the highest plant height average and number of leaves were obtained in a media combination of MS + Kinetin 2 mg L-1, MT, and MS + Kinetin 3 mg L-1. The highest transformation efficiency was in the nucellar embryo explant, while the highest regeneration efficiency was in the zygotic embryo explant. The highest shoot tip grafting percentage was achieved in the cotyledon node explant at 100%. In the grafting phase, the putative transformants before and after artificial bacterial inoculation showed that Ponkan 606 and Ponkan 597 had the highest plant heights, respectively. The intensity of Huanglongbing attacks after bacterial inoculation showed that three genotypes did not show HLB symptoms in the 24th week of observation, namely genotypes 598, 606, and 607. This study concluded that gene transformation in citrus plants produced three genotypes that did not show HLB symptoms.

Abstract

Tetraploid citrus are important for interploidal hybridization to create triploid seedless citrus. Colchicine is the most commonly used as antimitotic agent to induce polyploid plants. Tetraploid induction by colchicine in Pummelo ‘Nambangan’ was conducted in vitro using different types of explants. The aim of this research was to induce tetraploid pummelo ‘Nambangan’ by colchicine treatment using germinated seed, shoot tip and cotyledonary node as explants. Tetraploid shoot induction was conducted by soaking germinated seeds, shoot tips and cotyledonary nodes in 0.1 % colchicine for 1, 3 and 5 hours. Regenerant shoots were grown on MS medium and their growth was observed after four weeks in culture. Ploidy level was determined using flow cytometry analysis. Stomata density, length and width of stomatal guard cell were also recorded. The results showed that shoot elongation was inhibited by colchicine treatment. Soaking of shoot tip explants in 0.1 % colchicine for 1 hour resulted in 66.66 % of putative tetraploid shoots. Compared to diploid shoots, tetraploids had lower stomata density but bigger in guard cell size.

Abstract

One of difficulties in mangoes hybridization is polyembryonic seeds. This phenomenon reduces the chance of recovering true hybrid seedlings. The identification of the zygotic embryo is difficult and the possible approach is by using molecular marker. The objective of this study was to evaluate the utilization of two different marker systems (dominant markers and SSR) to characterize the occurrence of zygotic or nucellar embryo in polyembryony mango cultivars Garifta Merah, Lalijiwo, Manalagi, Madu, Saigon Kuning, and Saigon Merah. The type of embryo was evaluated by comparing the exhibiting amplification patterns, if different from the mother plant considered as zygotic and identified as nucellar if they exhibited the same banding pattern as the mother plant. From both of this marker systems out of the 16 SSR and 16 evaluated dominant primers, nine primers of each systems amplified the largest number of allele and sharply defined band. Dendogram analysis showed that the evaluated dominant markers could distinguish the zygotic and nucellar embryo clearly compare to evaluated SSR primers. The number of zygotic embryos derived from SSR was 64% and dominant markers were 47%. Based on zygotic and nucellar size, number and position, indicating no relationship between the type of embryo and embryo size, number and the position.
