Against the background of man-made impact on environment, role landscape architecture increases. Green plantings reduce adverse factors. A special is given to coniferous plants that perform environmental-improving functions all year round. The collection VNIISPK arboretum includes more than 310 species, forms and varieties woody representing 31 families. most numerous family Pinaceae 5 genera, ...

Plant species capable of hyper-accumulating heavy metals are of considerable interest for phytoremediation, and differ in their ability to accumulate metals from the environment. This work aims to examine (i) arsenic accumulation in three fern species [Chinese brake fern (Pteris vittata L.), slender brake fern (Pteris ensiformis Burm. f.), and Boston fern (Nephrolepis exaltata L.)], which were ...

This study evaluated the ability and mechanisms of 19 Pteris and non-Pteris species to accumulate arsenic (As) in a hydroponic system spiked with 300 microM As. The study included four Pteris vittata accessions (China, India, Poland, and the United Kingdom), P. biaurita and 17 non-Pteris species. Among the accessions, P. vittata from China and UK were the most and the least efficient in terms o...

We investigated the responses of stomata to light in the fern Adiantum capillus-veneris, a typical species of Leptosporangiopsida. Stomata in the intact leaves of the sporophytes opened in response to red light, but they did not open when blue light was superimposed on the red light. The results were confirmed in the isolated Adiantum epidermis. The red light-induced stomatal response was not a...

Coarse wood debris (CWD) plays a critical role in forest productivity, nutrient cycling, decomposition, and carbon sequestration, shapes the pool ecosystem. However, elemental composition of CWD varies among different types decay classes for same dominant tree species (Pinus koraiensis, PK). We compared across (Picea koraiensis-Abies nephrolepis-Pinus koraiensis (PAPF), Betula costata-Pinus (BP...
