Effect of morphactin on peroxidases and its relationship to rooting hypocotyl cuttings of Impatiens balsamina

K. K. Nanda, N. C. Bhattacharya and N. P. Kaur

Department of Botany, Panjab University Chandigarh-14, India

Morphactin inhibited the production of roots on hypocotyl cuttings of Impatiens balsamina with intact apex and cotyledons. Roots were, however, initiated when cuttings were transferred to water. A new peroxidase isoenzyme in the cotyledons and two in the hypocotyls that were absent in controls, appeared in morphactin-treated cuttings. However, one isoenzyme in the cotyledons and three in the hypocotyls that were absent in morphactin-treated cuttings, were detected in the controls. These isoenzymes may be involved in the initiation and development of roots.
