图1. 杉木家系M1 (A)和M4 (B)放射自显影。黑化部分为含32P部分, 黑化程度越高32P含量越高; 每一列图像从上到下代表整株杉木苗地上部上端、地上部下端和根部; 每个处理时间的图像左侧代表低磷处理杉木苗自显影, 右侧代表高磷处理杉木苗自显影。
Fig. 1. The autoradiography of M1 (A) and M4 (B) for Chinese fir family. The blackening part indicates the parts containing 32P of the fir seedlings. The higher the degree of blackening, the higher the content of 32P. Each column of images from top to bottom represents the upper part of the shoots, the lower part of the shoots and the roots. The left and right image for each processing time represents the autoradiography of the fir seedlings under low and high P treatment, respectively.
