Study on the Effects of Mix-sowing with Bromus Inermis on Changes of Physiological Parameters of Alfalfa Root in Wintering Period
This study was to analyze the effect of alfalfa mix-sowed with Bromus inermis on root physiology index.Four alfalfa cultivars,' Xunlu',' Longmu806',' WL168HQ',' Aohan' and one Bromus inermis were used as experimental materials.The results showed that the different physiology index,such as soluble carbohydrate content in root increased with the decrease of the temperature in late fall,and decreased with air temperature rise.The content of MDA showed an up-down-up trend with temperature variation.The comprehensive analysis showed that the mix-sowing were favorable to improve cold resistance of alfalfa.
