The Effects of Plant Growth Substances on Rind-Regeneration after Girdling in Solanum melongena cv. esculantum

Abstract: This paper deals with the effects of four plant growth substances, ic. IAA, NAA, 2,4-D and GA and their different concentration on rind-regeneration after girdling in Solanum melongen var. esculantum. The formation of callus was promoted by IAA, NAA and GA, but retarded by 2,4-D in early stage. The initiation of vascular cambium in callus was retarded by all these substances. However, an increase in amount of xylem was promoted by IAA at low concentrations. The different concentrations of NAA and GA affected a decrease in amount of xylem. The formation of "bundled" vascular tissue was impelled by NAA, GA and 2,4-D. The initiation of phellogen was promoted by IAA and NAA at high concentrtion. In addition, the nest-like tracheid mass was induced in callus by IAA and NAA frequently.

Key words: Solanum melongena var. esculantum, Girdling, Rind-regeneration, Plant growth-substances
