"I would highly recommend this book to all scientists who are engaged in tree physiology and also to forestry students. I encourage environment protection students to study the issue of acidification of ecosystems from sulfur and nitrogen deposition and the consequences of this process on forest ecosystems (temperate forest and tropical forests) in the global scale. Moreover, they will find much interesting information concerning tropospheric ozone as an important component of photochemical smog, which induces gene expression in deciduous and coniferous trees."
