Abstract

The objectives of the experiment were to evaluate effectiveness of seed treatments to eliminate Cmm of infected tomato seed lot, evaluate physiological quality of Cmm infected tomato seed lot after treatments with plant extracts. The research used curcuma rhizomes, betel vine leaf extract, cinnamon and clove oil to eliminate Cmm in tomato seed. Part of the seeds were dipped in either suspension of curcuma rhizomes, betel vine leaf extract, cinnamon and clove oil for 20 minutes and the others were matriconditioned using a mixture of burned rice hull (at 22 0C and RH 60-70%) plus either of plant extracts or oils. Elimination of Cmm from infected seeds was observed 10 days after treatments, and physiological seed qualities were evaluated before and after seed treatments. Results of the experiment indicated, dipping infected seeds in either 5% of curcuma, betel vine extract, cinnamon oil or 0.5% of clove oil suspension or matriconditioning plus either these extracts, eliminated 99% of infected Cmm on tomato seeds. Seed treatments using plant extracts for elimination of Cmm did not reduce seed germination, germination rate, vigor index, and did not increase time to reach 50% total germination (T50) of infected tomato seed except the seed treatment by using 5% cinnamon oil with or without matriconditioning.Key words: plant extracts, physiological quality, seed viability, vigor

Abstract

ABSTRACTThe development of an effective Agrobacterium transformation for tomato depends on several factors including plant genotype, explant vigor, Agrobacterium strain, selection system and culture conditions. It has been reported that tomato genotype contributed to success of transformation and regenerability in tissue culture. The purpose of this experiment was to study of regeneration response of four tomato genotypes and genetic transformation of tomato through Agrobacterium tumefaciens vector. The experiment of tomato genotype regeneration study was conducted at Biotechnology Laboratory, Asian Vegetables Research and Development Center (AVRDC), Taiwan, meanwhile the experiment of tomato genetic transformation study was conducted at Molecular Biology Laboratory, Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD), Bogor. Three of well-adapted genotypes in Indonesia i.e. Intan, Gondol Hijau and CL6046 were used as regeneration response experimental materials. AVRDC’s genotype, CLN1559A, was used as a control genotype in in-vitro culture. The result of experiment showed that there was variation response on the ability of explant to regenerate and form the shoot among the four genotypes. The control genotype, CLN1559, was the most regenerable genotype that indicated by the highest number of regenerated explants and shoots per explants (90,56% and 0,66), followed respectively by Intan (66,22% and 0,37), CLN6046 (45,94% and 0,26) and Gondol Hijau (17,08% and 0,09). Based on the results, among of the well-adapted genotypes in Indonesia, Intan was the most responsive genotype to be regenerated compared with two other genotypes. Considerably, Intan could be used as an explant for study on genetic engineering tomato through A. tumefaciens vector. The results of genetic transformation study have successfully obtained several explants formed the callus dan shoot on medium selection containing 50 mg/l kanamycin. Nevertheless, transformaton efficiency in the experiment still low which of 55,7 explants in average generated 1,7 shoots (about of 3%) that survive on selection medium (50 mg/l kanamycin). Keywords: Lycopersicon esculentum Mill., Regeneration, Genetic Transformation, Agrobacterium tumefaciens
