Abstract:

The survival rate and growth status of transplanting in vitro plantlets with roots of tetraploid Ziziphus acidojujuba were investigated under different conditions, including training days, medium, air relative humidity, plant height, root quantity and transplanting time. The results showed transplant should be carried out from the end of April to June. After 3 days training cultivation, plantlets with 7 or more roots and the height of over 5 cm were transplanted in vermiculite, perlite and soil (1:1) or vermiculite and soil (1:1). The air relative humidity was kept over 90% during the early stage of transplanting. The survival rate would be more than 70%.
