The substructure of pollen exine in Cedrus deodara (Roxb.) Loud, and Metasequoia glyptostroboides Hu et Cheng has been examined with an atomic force microscope (AFM). The results indicate that the exine substructure units containing sporopollenin in t

本文提出一种新的指纹脊线提取方法。首先利用灰度形态学,结合条件模板进行滤波,然后用Otsu方法分割得到二值图像,再将原图反相,进行上述同样处理,最后融合两次分割的结果,提取指纹脊线。实验结果证明本法具有抗噪性、旋转不变性。

采用同位素双标记技术 ,通过研究各种处理的棉花果枝韧皮部14 C -同化物和3 H -H2 O的运输情况 ,计算并比较二者的加权速率平均值 ,说明了韧皮部同化物和水存在一定程度的相对运动 ,这种相对运动可能是由于3 H -H2 O和筛管外细胞及胞间隙中的大量存在的非标记水发生侧向交换的结果 ,并说明这种一定量的相对运动与韧皮部同化物以液流形式运输的学说并不矛盾
