不同玉米杂交种萌发期及花期抗旱性研究

摘要

针对近几年持续干旱现象,选泽黑龙江省常用的8个玉米杂交种进行了萌发期抗旱鉴定,花期进行了气孔导度和蒸腾速率的测定以及后期关于植株外部形态及产量相关性状的测定。结果表明：先玉335、龙单23和龙单13为相对比较抗旱品种。%Aiming at the continuous dry phenomenon in recent years,8 normal maize hybrids in Heilongjiang province were chosen to conduct the drought resistance identification in germination stage,transpiration rate and stomatal conductance determination in flowering stage,and the external form and yield related properties determination in the latter stage.The results showed that the varieties of Xianyu335,Longdan 23 and Longdan 13 were relatively drought resistant varieties.
