摘要: 针对河北省平原区少雨干旱的气候特点,为筛选理想的抗旱节水油葵品种,研究了河北省平原区目前生产中种植面积较大的16个油葵品种在干旱胁迫下的生物性状、经济性状的变化以及干旱胁迫对于油葵叶片相对电导率(REC)和相对水分含量(RWC)等生理指标的影响,并对参试品种进行抗旱指数鉴定。结果表明,不同油葵品种在干旱胁迫下其生物性状、经济性状、生理指标的变化具有较大的差异性,通过综合筛选评价,庆丰1号、早油66和矮58为综合抗旱能力强的资源,其抗旱指数分别达到1.16、1.14、1.04,适宜在区域内进行推广种植。

Abstract: Facing the rainless and drought climate in Hebei plain,in order to screen the ideal drought-tolerant and water-saving oil sunflower varieties,16 oil sunflower cultivars which were comparatively widely grown in production in the plain were studied. The biological traits, economic traits, the relative eclectric conductivity(REC) and relative water content (RWC) of leaf were ananyzed under droutht stress condition and their drought resistant indices were also calculated for drought-tolerance identification. The result indicated that different oil sunflower varieties presented great variation in biological traits, economic traits and physiologic indices under droutht stress condition. By a general way of identificatioon, the screened highly drough-tolerant variety resources were Qingfeng No.1, Zaoyou 66 and Ai 58 with DRI (drought resistant index) 1.16, 1.14 and 1.04, respectively, and they were suit for growing in the area.
