Effects of temperature on the micropropagation of Groriosa superba L.
The effects of temperature on the formation and growth of shoot and tuber in the micropropagation of Gloriosa superba L. were investigated. The explants formed the greatest number of shoots at 30℃, and the shoot formation was inhibited at 15℃. At 30℃, a lot of tubers, produced in vitro, sprouted and formed secondary shoots. The optimal temperature for tuber growth in vitro was 20℃. These results suggested that the optimal temperature for shoot formation differed from the temperature for the tuber growth in vitro in the micropropagation of G. superba L.
