Changes in porphyrins and chlorophylls during the development of hiperhydricity in micropropagated shoots of Lupinus polyphyllus
This work studies changes in porphyrins during the development of hyperhydricity. Micropropagated shoots of Lupinus polyphyllus showed thick broad leaves that were translucent, wrinkled and/or curled and brittle, symptoms of hyperhydricity. The ratio between dry and fresh weight (%) dropped from 14....
