摘　　要：以5个籼稻杂交组合的F1为试材,详细研究了外源脯氨酸对籼稻花药诱导愈伤组织的影响。同时研究了水分胁迫处理对籼稻绿苗分化率的影响。结果表明,通过添加适量的外源脯氨酸及一定的水分胁迫处理,可以进一步提高花药培养力,降低花培成本,使花培育种更加经济、有效。With anther culturing of first generation of five lndica rice hybridization combinations, this paper studied the in- fluence of extrinsic proline on the callus, and the influence of water stress on improving the green plantlet differentiation frequency. The results showed that appropriate extrinsic proline and proper water stress could improve the effect of anther culture and reduce the cost. It could make the breeding of anther culture more obvious economy and effective.
