Abstract

The effect of red- and blue-light-emitting diodes on shoot and root growth of Hybrid Franc grape, a rootstock cultivar, along with two other grape genotypes, Kadainou R-1 and Vitis ficifolia var. ganebu, were investigated in vitro. Plants cultured under red-light-emitting diodes produced the longest shoots with longer internodes for all genotypes. The chlorophyll content measured as SPAD value and leaf number per explant were highest on plants cultured under blue-light-emitting diodes in all the genotypes. Blue light was also responsible for a higher number of stomata in all the genotypes; however, there was no significant difference in size of stomata in all genotypes under the different light conditions tested. Different light-emitting diodes did not affect the rooting percentage of Hybrid Franc but red-light-emitting diodes gave a higher rooting percentage along with higher root numbers for the two other grape genotypes.
