为了提高红麻愈伤组织不定芽诱导率,以红麻子叶和胚轴为外植体,采用两种途径诱导红麻不定芽分化,对影响红麻不定芽分化的培养基组成因素进行研究。结果表明:(1)在诱导愈伤组织分化不定芽的途径中,两种外植体均可诱导产生愈伤组织,但是胚轴产生的愈伤组织质量优于子叶。在分化培养基MS+6-BA (1mg/L)+2,4-D (1mg/L)+GA3(1mg/L)中,愈伤组织可分化少量不定芽,但是分化率较低;当该分化培养基中添加0.3%的活性炭时,愈伤组织在分化不定芽的同时也产生了大量不定根。(2)在通过直接诱导外植体分化不定芽的途径中,胚轴难以诱导产生不定芽,子叶可有效诱导不定芽;在MS+TDZ (0.1 mg/L )+NAA (0.1mg/L)的诱导培养基中,子叶的不定芽诱导效果最好,诱导率为64.29%。而在诱导培养基中添加 AgNO3后,不定芽的诱导率明显提高,其诱导效果最好的培养基为 MS +TDZ (0.1mg/L)+NAA (0.1mg/L)+AgNO3(1mg/L),此时不定芽诱导率可达85%。
為瞭提高紅痳愈傷組織不定芽誘導率,以紅痳子葉和胚軸為外植體,採用兩種途徑誘導紅痳不定芽分化,對影響紅痳不定芽分化的培養基組成因素進行研究。結果錶明:(1)在誘導愈傷組織分化不定芽的途徑中,兩種外植體均可誘導產生愈傷組織,但是胚軸產生的愈傷組織質量優于子葉。在分化培養基MS+6-BA (1mg/L)+2,4-D (1mg/L)+GA3(1mg/L)中,愈傷組織可分化少量不定芽,但是分化率較低;噹該分化培養基中添加0.3%的活性炭時,愈傷組織在分化不定芽的同時也產生瞭大量不定根。(2)在通過直接誘導外植體分化不定芽的途徑中,胚軸難以誘導產生不定芽,子葉可有效誘導不定芽;在MS+TDZ (0.1 mg/L )+NAA (0.1mg/L)的誘導培養基中,子葉的不定芽誘導效果最好,誘導率為64.29%。而在誘導培養基中添加 AgNO3後,不定芽的誘導率明顯提高,其誘導效果最好的培養基為 MS +TDZ (0.1mg/L)+NAA (0.1mg/L)+AgNO3(1mg/L),此時不定芽誘導率可達85%。

Cotyledon and hypocotyl were used as explants to study the influential factors of kenaf ad -ventitious buds differentiation through two approaches.The results showed that:( 1 ) in the approach of callus induction , the quality of hypocotyl callus was better than cotyledon , callus could be induced to dif-ferentiate a few adventitious buds in the medium of MS +6-BA (1mg/L) +2, 4-D (1mg/L) +GA3 (1mg/L), but the induction rate was very low.After adding 0.3%activated carbon in the medi-um, many roots were induced along with adventitious buds.(2) In the approach of inducing explants di-rectly, hypocotyl hardly generated adventitious buds , cotyledon could induce adventitious effectively.Cotyledon could get the highest induction rate in the medium of MS +TDZ ( 0.1 mg/L ) +NAA (0.1mg/L), and the rate was 64.29%.After adding AgNO3 in the medium, the rate could increase ob-viously.The best induction medium was MS +TDZ (0.1mg/L) +NAA (0.1mg/L) +AgNO3 (1mg/L) , and the adventitious buds induction rate was 85%.
