图1. 供氮水平对大豆根瘤豆血红蛋白(Lb)浓度及固氮能力的影响
(A) 根瘤横切图; (B) 豆血红蛋白浓度; (C) 固氮酶活性。实验设置4个生物学重复, 每个重复随机取2或3个根瘤测定豆血红蛋白浓度和固氮酶活性。数据为10个根瘤的平均值±标准误。不同小写字母代表不同供氮水平间差异显著(P<0.05)。Bars=2 mm
Figure 1. Effects of nitrogen supply on leghemoglobin (Lb) concentration and nitrogenase activity of soybean nodules
(A) Cross section of nodules; (B) Leghemoglobin concentration; (C) Nitrogenase activity. There were 4 biological replicates, 2 or 3 nodules were randomly harvested for Lb concentration and nitrogenase activity analysis. Data are means±SE from 10 nodules. Different lowercase letters indicate significant differences among different N supply levels (P<0.05). Bars=2 mm
