  • The effects of plant regulators on direct somatic embryogenesis in liquid culture of Rehmannia glutinosa were investigated and the proper explant for direct somatic embryo formation was studied. Direct somatic embryos were induced from leaf segments culture in the MS liquid medium containing 0.5 mg/l of both IAA and NAA, while IBA of 1.0 mg/l was required for the same effect. Many somatic embryos were directly formed at the concentration of 2.0 mg/l cytokinin such as BA, kinetin and zeatin, but somatic embryogenesis was relatively poor at above or below this level. Relatively more somatic embryos were induced in the combination of 1.0mg/l IAA and 2.0mg/l zeatin. Formation of somatic embryos begun after 6 weeks on stem segments, while 7 weeks both on petiole and leaf. However, overall production of somatic embryos after 8 weeks was higher in leaf segment than that of stem segment.

  • This experiment was carried out to elucidate the effect of planting depth on the Quality and yield in Rehmannia glutinosa. Planting depths were 3,6,9 and 12cm, and planted on April 18. Emergence rate was decreased in the order of 86% in 3cm, 67% in 6cm, 37% in 9cm and 21% in 12cm. Leaf length was longer about $0.3{\sim}0.8cm$ in planting depth 6-12cm than that of 15.6cm in planting depth 3cm. Yield of Rehmannia glutinosa were lower 5% in planting depth 6cm, 62% in 9cm and 68% in 12cm than that of l,154kg/10a in planting depth 3cm. And optimum planting depth was considered 6cm.

  • The nucleotide sequence of a Korea isolate of broad bean wilt favavirus from Rehmannia glutinosa Lib., designated BBWV-RE, was determined. Direct amino acid sequencing of the virus coat proteins suggests that a comparison of several favaviruses in terms of nucleotide sequence and amino acid sequences showed that BBWV-2 isolates display high sequence identity. The small coat protein genes of RNA-2 were also determined for three other Japanese isolates(E, L, and 1-2) and two ATCC isolates(PV132 and PV176) of BBWV. the CP sequence suggested distinct evolution lineages. Serotype 2 favaviruses are more prevalent in Asia, Australia and North America, Wheres serotype 1 is more prevalent in europe.(중략)
