Studies on Histology and Histochemistry of the Morphogenesis of Stem Segment in Chinese Gooseberry Cultured in vitro
Gui Yao-lin and Xu Ting-yu
The stem segments of Chinese gooseberry cultured in vitro, 2ip added in the medium would give good effect on the regeneration of the plantlet same as zeatin. The effect of 6-BA was less and kinetin almost had no effect. Inhibition was found in almost all cases, when gibberellie acid (GA3) or GA3 (1,5, 10 ppm) combined with zeatin was used. Calli were originated from cambium and ploem. The primary xylem elements also participated in the formation of callus. The shoot primordium originated from the surface cells of callus and the subepidermal cells also participated in it. In certain conditions, shoot primordium was produced from internal part of callus. During the shoot primordium formed, a positive correlation between the starch accumulation and primordium formation could be obtained. The accumulated starch in the cells gradually disappeared as the shoot formation proceeded.
