Abstract
The amyloplast DNA of potato tuber (Solanum tuberosum L.) and lily scale (Lilium davidii var. willmottiaeRiffill)were studied. Feulgen, toluidine blue and DAPI (4'6-diamidino-2-phenylindole) were used for starning, all results showed identical location and shape of the amyloplast DNA. The changes of amyloplast and amyloplast DNA in different development stages were also observed, indicating the relationship among the amyloplast core, crystal structure and the amyloplast DNA. Results showed that the earliest appearance of amyloplast DNA was on the amyloplast core. Crystal structures were formed by the copies of DNA, and the radio-shape of the crystal structure resulted from the continuous copies of amyloplast DNA in the development stages.
