記事区分：資料Virus-free-plants of strawberry (Fragaria ananassa) are produced by meristem culture with a special technique, and enough young plants for commercial cultivation have been prepared over the past ten years. To improve the technique, the capacity of the runner-meristem, anther, and filament to form callus, and the growth of the callus obtained, were compared on the MS medium. The three cultivars Nyohou, Toyonoka, and Houkouwase were studied. The anthers of Houkouwase and Nyohou formed callus more readily than their runner-meristems and filaments. Filaments of Toyonoka formed callus more readily than its runner-meristems. In anther cultures, more calli were formed on media containing lower benzyladenine (BA) and higher auxin (NAA or 2,4-D) concentrations, or lower kinetin and lower auxin (NAA or 2,4-D) concentrations. Anther length and its callus-forming capacity were correlated. Most of calli from long anthers stopped growing within eight weeks after the start of culture. Calluses from anthers and filaments grew faster than those from meristems.
