The potential values of cereal crops may be excavated by multiplying the chromosomes 通過(guò)多倍化途徑有可能進(jìn)一步挖掘禾谷類作物的潛在利用價(jià)值。
Together with other lines of evidence , we propose that polyploidization is still an ongoing process in grasses of polyploidy origins 參照其它類群演化式樣,提出多倍化仍然在禾草的多倍化起源方面起作用。
The content in the paper is included in the man - induced technique , biological characters of polyploid and the potential values 摘要綜述了禾谷類作物的人工誘導(dǎo)、生物學(xué)特征特性、多倍化過(guò)程中基因組的動(dòng)態(tài)變化研究及其潛在價(jià)值。
The bmn cells are multiploidy and heteroploidy so highly that in which the diploid was few and far between , and multiploid was so much that came to 90 % . even there were 533 chromosomes in one cell Bmn細(xì)胞是高度異倍化、高度多倍化的細(xì)胞系,其典型二倍體極少而高多倍化群達(dá)90 ,最多的染色體一群在500條以上。
The results are basically comparable with those obtained from studies on morphology , cytology , biochemistry and phytochemistry . a significant intraspecific differentiation among the populations of a . hookeri was confirmed by the use of rapd analysis . differentiation level of not withering in the winter populations is higher than that of withering in the winter ones Rapd研究結(jié)果與細(xì)胞學(xué)研究、植物化學(xué)研究和生物化學(xué)的研究結(jié)果基本一致,表明寬葉韭內(nèi)的確存在著明顯的種內(nèi)分化現(xiàn)象,而多倍化可能為寬葉韭進(jìn)化的趨勢(shì)。
