摘要/Abstract

摘要： 在灭菌土和未灭菌土盆栽系统中,研究了大豆种子的表面初始接种量对费氏中华根瘤菌HN01DL在大豆根圈中的定殖动态与结瘤的影响。结果表明,与3个接种量对应的早期根圈定殖动态和水平有明显差异,但随着宿主植物根系的生长其差异逐渐减小,整个定殖动态曲线的变化和定殖密度趋向一致,并且发现3个不同的初始接种量对HN01DL在大豆黑农33根系上的结瘤数量和占瘤率没有显著影响。

Abstract: The effects of different initial inoculate rate on the surface of soybean seed on root colonization dynamics and nodulation in soybean rhizosphere by Sinorhizobium fredii HN01DL in sterilized and non-sterilized soil pot microcosm were studied. The results showed that the root colonization dynamics and level at the very early stage were significantly different due to the three different inoculation rates. But the difference decreased gradually with the growth of host plant root system. The entire colonization dynamics curve and colonization density tended to change in the same direction. It was also found that there was no obvious influence on nodulation number and nodule occupancy by three different initial inoculation rates in the root system of host soybean Heinong 33 variety.
