1题目为了探究6-BA和IAA对某菊花品种茎尖外植体再生丛芽的影响,某研究小组在MS培养基中加入6-BA和IAA,配制成4种培养基(见表1),灭菌后分别接种数量相同、生长状态一致、消毒后的茎尖外植体,在适宜条件下培养一段时间后,统计再生丛芽外植体的比率(m),以及再生丛芽外植体上的丛芽平均数(n),结果如表1所示。
1 Title In order to investigate the effect of 6-BA and IAA on shoot regeneration of shoot explants of a certain chrysanthemum variety, a research team added 6-BA and IAA to MS medium to prepare 4 kinds of medium (see Table 1) , After inoculation were sterilized with the same number, the same growth state, sterilized shoot tip explants, cultured under suitable conditions for a period of time, statistics regeneration regeneration bud explant ratio (m), and regeneration of bud explants Body buds average (n), the results shown in Table 1.
