Cytokinins and coconut water promoted abnormalities in zygotic embryo culture of oil palm

Abstract

Induction of adventitious shoot formation from mature zygotic embryo of oil palm was carried out in liquid MS mediumsupplemented with various types of cytokinins. Kinetin (KN) alone at concentration of 0.5 mg/l gave the highest adventitiousshoot formation at 13.4%. However, abnormal shoots in form of inflorescence-like structure (ILS) were obtained in 5mg/l KN containing medium. For coconut water a big ILSs were formed at 10.6%. Histological studied revealed that thoseinflorescences had no clear floral organs.
