SADAR UDDIN SIDDIQUI, M. FAYYAZ CHAUDHARY* AND RASHID ANWAR

Abstract: Meristan tip culture of potato (Solanum tuberosum L) were established on MS medium containing BA and NAA and multiplied on hormone free MS medium. Potato culture survival and growth was significantly influenced by storage period and the incubation temperature, whereas, stress levels significantly affected shoot growth where its effect on survival was non-significant. A temperature of 25°C and longer storage period adversely affected the culture survival.
