Abstract

The objectives of this research were to estimate responses of several sweet potato genotypes in preservation media through in vitro slow growth preservation, and to achieve cheap and accessible media. Experiment was arranged in a completely randomized design with a single factor. The experimental factor was sweet potato genotype (Sukuh, 421.34,343.15 and 2040.8). These genotype were tested in a preservation media which consisted of 15% coconut water +  30 mg/l aspirin + 50 g/l sucrose + 7 g/l agar. Experiment was replicated four times. Data was analyzed parametrically and non-parametrically. The result showed that genotype gave high responses to preservation media. Genotype Sukuh produced highest leaves while genotype 421.34 yielded highest numbers of root and internode. In the preservation medium of Genotype Sukuh through in vitro slow growth preservation, aspirin could be added to inhibit growth by increased leaf senesence. This experiment also showed that Hiponex (20:20:20) could be used as the basic media for in vitro preservation of sweet potato

Abstract

The objective of this research was  to obtain suitable concentration of sucrose and agar in the sweet potato (Ipomea batatas (L) Lam) in vitro preservation medium, in order to make plant grow slowly and healthy. Experiment was done in Molecular Biologi Laboratory of PAU IPB. The experiment was arranged in factorial complete random design, using sweet potato var. Sukuh in order to know the effect of sucrose (40,50,60,70 and 80 g l-1) and agar (7 and 8 g l-1) which were added 1 g l-1 hyponex fertilizer 20-20-20. The experiment was replicated four times. Data were analyzed parametrically and non-parametrically. The result of these experiments showed the suitable conservation media was 1 g l-1 hyponex 20-20-20 + 60 g l-1sucrose + 7 g l-1 agar. Threfore, the media composition MS could produce high green inter nodes number, high root number and more than two green leaf number. This experiment also showed that MS media could be replaced by a cheaper and easily found conservation medium.
