[Massive multiplication of coffee (Coffee arabica L. cv. Catimor) through embryogenic cell suspension culture].

Abstract

Cell suspensions offer several advantages as a system for massive propagation because of the high rates of multiplication, the higher homogeneity in the culture conditions and the possibility of automatization. In this study, different experimental conditions were analyzed to establish embryogenic cell suspension cultures of coffee. The best conditions to establish the embryogenic cell suspension cultures of coffee were as follows: coffee leaf sections were cultivated during 12 weeks (Stage I) in a solid medium with the Murashige and Skoog salts, 2 mg/l kinetin and 0.5 mg/l 2,4-dichlorophenoxiacetic acid (medium 1). Under these conditions the explants formed a callus tissue that was transferred to a liquid medium containing 5 mg/l of 6-benzylamlno-purine (medium 2). After 12 days in a shaking liquid medium (Stage II), the cultures were sieved and were maintained In the same media, which was renewed every eight days (Stage III). This method yielded 1884 embryos in 50 ml; placing the embryos under conditions for germination yielded plantlets of normal appearance.
