The effect of tree shelter on the growth and anatomy of bark and wood of cork oak (Quercus suber L.) seedlings was evaluated one year after planting. Stem cross sections were examined and percentage of tissues (vessels, axial parenchyma, rays and fibres) and diameter of vessels analysed. The cork oaks responded to the effect of shelter tubes with a 22% increase in apical growth and a 35% decrease in radial enlargement resulting into highly significant differences in the diameter-to-height ratio (0.099 and 0.193 respectively for sheltered and unsheltered plants). The stem anatomy showed adaptations to the protected environment of the shelter: the sheltered plants had a significantly higher percentage of parenchyma (30% vs. 19%, P < 0.001) and lower percentage of wood fibres (40% vs. 47%) compared with unsheltered plants. Annual rings were less clearly visible in the sheltered plants. These observations suggest that trees grown in protective shelters are less able to withstand the environment than those directly subjected to it.

Pine trees around the Chernobyl Nuclear Power Plant, Ukraine, were investigated by light- and electron-microscopy as well as UV-microspectrophotometry in order to find out whether the accident on April 26 in 1986 affected the structure of xylem formed. The analysis of increment cores did not reveal any influence on the amount of xylem formed in 1986, but there was a distinct reduction during the subsequent three years. The xylem formation had recovered in 1990. ʻForkingʼ in the rows of tracheids was frequently seen at the cellular level in the 1986 tree ring. This phenomenon also occurred in the 1987 tree ring, but was less pronounced. It appears that the radioactive irradiation had no direct effect on the cambium in 1986, but affected the differentiation of xylem mother cells. The reduced wood formation between 1987 and 1989 appeared to be a consequence of the massive losses in needles in the year of the accident rather than of the uptake of radiobiologically active elements. The layering and lignification of the tracheid walls were not affected.
