The present invention will become more fully understood from the detailed description given hereinbelow and the accompanying drawings which are given by way of illustration only, and thus are not limitative of the present invention, and wherein:
FIGS. 1A-1C are images of transverse cutting and oblique cutting on protocorms processed in a method for producing polyploid plants of orchids in accordance with the preferred embodiment of the present invention;
FIG. 2 is an image of protocorms of diploid of Phal. aphrodite subsp. formosana being cut and cultured for 2-3 months in the method in accordance with the preferred embodiment of the present invention;
FIG. 3A is a flow cytometric histogram showing DNA content (i.e. c-value) of leaf cell nuclei of diploid of a regenerated plant of the third-generation PLB produced by the method in accordance with the preferred embodiment of the present invention, wherein C-value represents the multiple of the basic DNA content;
FIG. 3B is a flow cytometric histogram showing DNA content (i.e. c-value) of leaf cell nuclei of tetraploid of a regenerated plant of the third-generation PLB produced by the method in accordance with the preferred embodiment of the present invention; and
