摘　　要：为筛选耐盐碱向日葵品种,以14个向日葵材料作为试验材料,从盐胁迫对向日葵农艺性状、产量性状的影响及生理生化响应等方面入手,并通过灰色关联度分析和通径分析,探讨了盐胁迫下向日葵产量形成的主要因素。结果表明:0.26%盐分胁迫下与小区产量相关度最大的农艺性状是叶片数。0.39%盐胁迫下与小区产量相关度最大的农艺性状是株高。0.83%盐胁迫下与小区产量相关度最大的农艺性状是叶面积。0.26%盐胁迫下与小区产量关联度最大的产量性状是百粒质量。0.83%盐胁迫下与小区产量关联度最大的产量性状是单盘粒重。通径分析结果表明,盐含量为0.26%时,株高、盘径、百粒质量和结实率对向日葵小区产量具有较大的正向效应,其中百粒质量对小区产量的正向效应最大;盐含量为0.39%时,株高、盘径、百粒质量对向日葵的小区产量有较大的正向效应,但结实率的正向效应较小;盐含量为0.83%时,单盘粒质量对向日葵的小区产量有较大的正向效应,但结实率、百粒质量的正向效应较小。To screen the sunflower varieties with salt tolerance ,14 sunflower material as the experimental mate-rial,starting from the effects of salt stress on sunflower agronomic traits ,yield traits and physiological and biochemi-cal response ,and through gray correlation analysis and path analysis ,discusses under salt stress of sunflower yield formation factors .The main results are as follows:0 .26%stress associated with yield of agronomic traits is the num-ber of blades.In 0.39%under salt stress related to yield traits of maximum height .In 0.83%under salt stress re-lated to yield the greatest degree of agronomic traits of leaf area .Under salt stress is relatively light yield and maxi-mum yield correlation is 100 grain.Under severe stress and maximum yield correlation of yield is a single disc grain weight.Under different concentration of salt ,the response in the growth index of the sunflowers differences .Differ-ences related to yield traits on stress of different concentrations of salt is also great .The same index in different salt stress,positive and negative effects on yield are also different .
