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....

| Sumario: | 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 14.9 to 6.7. Chlorophyll content was reduced from 2512 to 499 μg g-1 frwt. The a/b chlorophyll ratio (5/1) did not change until the third week, it was then modified to 3/1. Porphyrin content was reduced from 20 to 5 μg mg-1 protein. Porphyrins with more carboxyl groups increased, while uroporphyrinogen III level was reduced. |
