The results showed that POD activity increased at first and then decreased in the skin and flesh of root. The peak occurred at 40 d and 60 d in the skin and flesh, respectively. POD activity in the skin was higher than that in the flesh at 30 d and then contrary results were observed. The higher POD activity was, the more POD isoenzyme was. The pattern of POD isoenzymes was different between skin and flesh at different vegetative growth stages. POD isoenzymes in the skin were composed of five monomers and four dimers while five dimers or two monomers, two dimers and one tetramer in the flesh. POD isoenzymes in the root were mainly acidic. POD localized mainly in the cell walls of periderm, cambium, xylem ray, xylem vessels and primary xylem.
结果显示,心里美萝卜营养生长期肉质根的皮和肉中POD活性均先升高后降低,分别在播种后第40 d和60 d出现峰值,30 d时皮中POD活性高于肉,之后则相反,酶活性最高时同工酶数目也最多,不同时期,皮和肉中同工酶种类不同;皮中POD同工酶由5个单体和4个二聚体组成,而肉中由5个二聚体或2个单体、2个二聚体和1个四聚体组成,均以酸性同工酶为主;组化定位显示POD主要分布在肉质根的周皮、形成层、木射线、木质部导管和肉的初生木质部等的细胞壁附近。

Because the strength of springwood was very low, the strength of board which included more springwood was low. The main reason why there was no difference in wet compressing shear strength between quarter-sawn board and flat-sawn board was that quarter-sawn board had a lot of pits on radial cell wall and in flat-sawn board xylary rays were transversely cut and left a lot of pores which provided a kind of tunnels for water.
造成柞木径切板的反复煮沸压缩剪切强度与弦切板的反复煮沸压缩剪切强度没有显著性差别的主要原因是柞木细胞壁径面上的纹孔很多,而弦面上的木射线在经刨削后是横断的,留下许多孔隙,这使得弦径向均有成为水分通道的孔隙,造成柞木径切板的反复煮沸压缩剪切强度与弦切板没有显著性差别。

The reasons why quarter-sawn board of Larch had smaller wet compressing shear strength than flat-sawn board of Larch for repeatedly boiling samples were as follows: first of all, antiswelling efficiency between springwood and summerwood of Larch was different; secondly, pits of Larch had great effect on this aspect.
造成桦木反复煮沸压缩剪切强度径切板的比弦切板的要大的主要原因是在弦切面木射线是被横断的,因此,在弦面上留下射线管胞的孔隙,在反复煮沸时这些孔隙成为了水分的通道,因而使桦木反复煮沸压缩剪切强度径切板的比弦切板的要大。

According to the observation of the microstructure of small diameter lumber with scan electron microscope, there are many bordered pits of the radial trancheidal wall in the small-diameter Larch, and most of them have pit film. The resin is not only in resin canal, but also in some trancheid and ray parenchyma cells. The drying defects of small-diameter Larch lumbers were the most severe in consecution heating, fluctuating-heats 2h in between, and drying defects were nearly not observed in fluctuating-heats 6h. There is tylosis in the vessel of the heartwood of small-diameter Cathay poplar. The bordered pits of the radial trancheidal wall are dense, and the pits between vessels are alternate, most of them have pit film. Different collapse happened in all the small-diameter Cathay poplar lumbers. The collapse of small-diameter Larch lumbers was the most severe with consecution heating, fluctuating-heats 2h in between, the least with fluctuating-heating 6h.
