Abstract

Gamma ray mutative induction for increasing genetic variation has been applied for plant prime variety engineering. The materials are derrived from seed organ, shoot and calli. Calli is a group of actively dividing cell and have not been organized to form plant. The benefit of using calli explant is that the gamma ray could directly shot to DNA in the nuclear cell in such a way that there is higher opportunity for genetic change to occur. The problema of using calli explant are the difficulties in regenerating the calli into shoots, due to the deformation as a result of radiation process. Therefore, this research is aimed at obtaining the appropriate media formulation for shoot regeneration from Fatmawati-rice calli which has been irradiated with gamma ray. The reseach was conducted in BB-Biogen laboratory consisting of three experiments, such as : (1) calli iradiation with the dosage of 0; 5; 10; 15; 20; 25; 30; 35; 40; 45; 50; 55 and 60 Gy, (2) shoot regeneration at the MS + BA (0, 1, dan 3 mg/l) + IAA (0 dan 0,8 mg/l) media, and BA (0, 1, and 3 mg/l) + zeatin ( 0; 0,1; 0,2 and 0,3 mg/l) + IAA 0,8 mg/l and (3) Shoot induction at MS + IBA (0, 1, 2 and 3 mg/l) media. The result shows that the range of LD50 was obtained at the dosage of 30 Gy, the most apropriate media for shoot regeneration is MS + BA 3 mg/l + IAA 0,8 + zeatin 0,1 mg/l and media for root induction is IBA 1 mg/l.

Abstract

In vitro culture can be applied for producing new genotype which is tolerant to biotic and abiotic or to incerase secondary metabolic content. To obtain the optimum result of variety improvement, regeneration system should firstly be found out.It is sufficiently difficult to regenerate pulai pandak (Rauwolfia serpentina L.). Hence, with this system, the improvement of R. serpentina with secondary metabolic content higher than the other. The mother stok of R. serpentina used in this experiment, belongs to the collection of BB-Biogen. Calli were produced from leaves and internodes which is cultured at medium MS contain 2.4-D (0, 1, 3,5, 7 mg/1) combined with caseine hydrolysate 3 mg/1. Regeneration medium was MS contain BA (0,5, 1 mg/1) combined with zeatin (0, 0.1 and 0.5 mg/1) and root formation used was three kinds of auxin (IBA, IAA and NAA). The result showed that inter nodels was better that leaves to callus induction. In this experiment, MS + 2,4-D 1 mg/1 + CH 3 mg/1 was the best medium to induct calli,while medium MS + BA 1 mg/1 + Zeatin 0,5 mg/1 + maltosa 3% to regenerate and MS + IBA lmg/1 for root induction.
