摘　　要：研究了浓度均为150mmol/L的9种碳源(含组合)对3个籼稻品种花药的愈伤组织诱导率的影响,发现麦芽糖为碳源的培养基效果最佳。进一步以7个灿稻、2个粳稻和4个杂交组合为材料,系统比较了150mmol/L的麦芽糖与蔗糖作为诱导培养基的碳源对花药培养的影响,结果表明,以麦芽糖为碳源的培养基上,平均愈伤组织诱导率和随后的绿苗分化率分别为54.81%与9.70%,而在相应的蔗糖培养基上,只有11.85%和3.30%,差异极显著。讨论了提高籼稻花培效率的策略,并建议采用统一的方法计算愈伤组织诱导率。The effect of different sugars (150 mmol/L for each) on callus induction in rice anther culture was innitially investigated by using three indica cultivars. Maltose resulted in greater microspore callus induction than sucrose and other sugars. Further experiments with 7 indiea, 2 japonica cultivars and several hybrids indicated that mean percentages of callus induction and then green plantlet regeneration were 54. 8% and 9. 70%, respectively, on maltose medium, which were significantly higher than those on sucrose medium. The strategy of raising the efficiency of indica rice anther culture and suitable calculative formula for callus induction rate are discussed.
