摘要: The ploidy levels of the in vitro and vivo plants T. roxburghianum were invariably tetraploid (2n=4x=44). chromosome number calli 2n=2x=22 2n=8x=88, amidst normal 2n=4x=44. Changes length, disparity index, variation coefficient total forma percentage noticed. diakinesis metaphase stages flower showed quadrivalents among bivalents, whereas same plant bivalents only.
