The secondary root number per plant of Yumai No 49,a mi d-s trength quality wheat,is the smallest among the three varieties except the winte r stage but its root system quality is the best;the intensity of reducing TTC an d the activity of SOD of fresh wheat root are the highest during the period fro m winter stage to flag leaf stage.Since flag leaf stage,its physiological charac ters are weaker and have bigger variation during whole stage.The secondary root number per plant of Yumai No 50,a soft quality wheat,is the biggest except duri ng winter stage,and its dry weight of root of single plant is the heaviest in ev ery stage.Before 19th,March,its intensity of reducing TTC is the weakest and dec reases abruptly after flag leaf stage,but its activity of SOD decreases slowly.R oot dry weight per plant of Yumai No 34,a high quality wheat,is the smallest amo ng the three varieties and its root system quality is the weakest.Before jointin g stage,the intensity of reducing TTC is stronger,but after that,it decreases sl owly though it is smaller,and the activity of SOD decreases slowly in every stag e.
