The formation of an oil bridge between adhesive seeds was observed microscopically. The geometry of the oil bridge was affected by the shape of the adhesive seeds. The capillary force of the oil bridge was estimated from the image captured by the microscope. The average capillary force was 127 microN, which was five times higher than the average gravity of the seeds. It was observed that several oil bridges formed between two seeds. These results indicated an adequate ability of the seeds to adhere. The capillary force of the oil bridge increased with surface oil content. The probability of formation of an oil bridge increased with surface oil content when the surface oil content was above 0.63%. The probability of formation of an oil bridge markedly increased when sucrose was added to the seeds.
通过显微镜观察到了粘性种子之间油桥的形成。油桥的几何形状受粘性种子形状的影响。根据显微镜拍摄的图像估算了油桥的毛细力。平均毛细力为127微牛，比种子的平均重力高五倍。观察到两颗种子之间形成了几个油桥。这些结果表明种子具有足够的粘附能力。油桥的毛细力随表面油含量的增加而增大。当表面油含量高于0.63%时，油桥形成的概率随表面油含量的增加而增大。当向种子中添加蔗糖时，油桥形成的概率显著增加。
