摘要
本文研究了吲哚-3-乙酸(IAA)、赤霉素(GA)和动素(kinetin)的市售制剂单独和联合对脂肪偶氮螺旋菌和巴西芽孢杆菌的影响。这些激素对形态、生长速度或摄氧量没有影响。GA、动素和激素组合(而不是IAA单独)对活细胞数量的一些随机影响被观察到。IAA浓度在0.001 ~ 1.0 μ g /ml范围内对脂孢霉的氮酶有抑制作用，对巴西芽孢霉无抑制作用。GA和动素单独或与IAA联合对氮酶活性无影响。
The behaviour of Azospirillum spp. in the presence of plant growth hormones.
Tests were carried out to determine the effects of commercial preparations of indole-3-acetic acid (IAA), gibberellin (GA) and kinetin, separately and in combination, on Azospirillum lipoferum and A. brasilense. These hormones showed no effect upon morphology, growth rate, or oxygen uptake. Some random effects of GA, kinetin and the combination of hormones--but not of IAA alone--were observed on the number of viable cells. IAA, in the concentrations 0.001-1.0 microgram/ml, inhibited nitrogenase in A. lipoferum but not in A. brasilense. GA and kinetin separately and in combination with IAA had no influence on nitrogenase activity.
