Anatomical changes of flag leaf by variety winter wheat in conditions water stress conditions

The density of stomata on abaxial and adaxial epidermis of flag leaves was measured at three experiments. The influence of water stress on plants was not uniquely determined, because the number of stomata was different in experimental years ...

Variability in wood anatomical characteristics in silver fir and European beech at three different sites in the Carpathian Mountains

Although the general anatomical features are species-specific and thus adjust their anatomical structure in response to changing environmental conditions (von Arx et al. 2016). Variability in wood anatomical traits. Variabi...
