常見例句雙語例句This paper reported that an in vitro embryogenic callus induction and plantlet regeneration system from immature zygotic embryos of hybrid larch was established.以未成熟合子胚為外植體，建立雜種落葉松胚性愈傷組織誘導(dǎo)和植株再生體系。The results showed that the sampling time (maturity) of immature zygotic embryos, concentration of 2,4-D and 6-BA had a significant effect on induction rates of callus.結(jié)果表明：未成熟合子胚的采樣時(shí)間（發(fā)育程度）、2，4-D和6-BA的濃度極顯著影響紅松愈傷組織的誘導(dǎo)率。 返回 zygotic induction
