Analysis of lower canopy temperature and physiological characteristics of cold type wheat under drought

FENG Bai-Li~1,ZHAO Lin~2,GAO Xiao-li~1,GAO Jin-feng~1,ZHANG Song-Wu~1,LI Sheng-xiu~2(1 College of Agronomy;2 College of Resources and Environment,Northwest A & F University,Yangling,Shaanxi 712100,China)  
Cold and Warm wheat cultivars were used to investigate their lower canopy temperature and some physiological characteristics by measuring their corresponding canopy temperature,duration of function leaves and MDA content.The results showed that canopy temperature was continuously lower in cold wheat cultivars than in warm ones,especially during kernel-filling period.Many of the physiological characteristics such as the functional period of leaves and MDA content in the former were superior to those in the latter.So the use and selection of the cold type wheats should be stressed in the wheat breeding and culture,for it is useful to improve crop yield and quality in dry farmland conditions.
