HISTOLOGICAL OBSERVATION ON THE GROWTH OF POTATO PLANTLETS IN VITRO UNDER SIX DIFFERENT LED LIGHT QUALITIES
Light quality significantly influences the growth and morphogenesis of potato plantlets in vitro. The aims of this study were to compare the effects of LED light qualities on the growth and shoot histology of potato plantlets in vitro. For the shoot height, the R treatment increased the shoot elongation, whereas the B treatment shortened the shoot length. For the shoot width, the B treatment increased the shoot width, while the R treatment made the shoot slender. Histological observation indicated that under the B treatment, the cell enlargement of vascular bundles, pith and cortex cells resulted in the increase of shoot width; under the R treatment, the cell sizes of the stem tissues were the smallest. The arrangement of stem components was similar among all treatments, but the cell sizes of stem tissue were affected by light quality significantly.
