Changes in the biochemical parameters of albino, hyperhydric and normal green leaves of Caladium bicolor cv. “Bleeding hearts” in vitro long-term cultures

Publication date: Available online 27 December 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): Tasiu IsahAbstractCaladium bicolor is an excellent landscape and pot plant grown for its ornamental value due to the varied shapes and multi-colored foliage. However, the ornamental value of in vitro clonally propagated plants is affected by the occurrence of morpho-physiological anomalies in the long-term cultures. During the long-term culture of rhizome-derived shoot cultures of C. bicolor cv. "Bleeding hearts", some incidences of hyperhydricity and albinism were observed. Hyperhydricity occurred at high frequency in the shoot cultures and was more prevalent in the liquid over solid medium cultivated plantlets. The addition of silver nitrate at 7.5 μM overcame...
