The excitable properties of conifer protoplasm consist of nitric oxide (NO) bursts that prime and prepare chemical messengers for the transmission of stressful environmental signals. NO in somatic and reproductive cells is produced in response to mechanical forces, gravity, wounding, changes in nutrition, hypoxia, drought, salinity, temperature shock, pollutants, and pathogen attack. NO arises primarily from nitrite via nitrite:nitric oxide reductase and nitrate reductase. It also arises from arginine N and oxygen via putative nitric oxide synthase activity. NO rapidly reacts with, oxygen species, hemes, thiols, and proteins to produce biochemical...

Research plots in Vojířov were established in a spruce stand and in a mixed stand. They are situated south of Jindřichův Hradec, near the border with Austria, on the ridge sloping to the Třeboň basin, exposed to western winds. The soils (Haplic Podzols) have developed on deep overlaps of eolian sands, between boulders of mica granite. Since summer 1991, the chemistry of precipitation water and run-off water from the O-humus horizon...

Differentiation of forest technologies according to ecosystem properties is a necessary step to achieve sustainable forestry. A forest typological system is considered to be the basic unit of ecosystem differentiation in the Czech Republic. Terrain characteristics, potential water erosion and applicable harvest technology were examined for 44 forest sites in a landscape segment of the Jizerské hory Mts. Forest site was found homogeneous in terms of terrain and technological properties. Edaphic category and groups of forest types as higher classification units and management sets as units of alternative classification showed lower homogeneity insufficient...
A short-term response of floodplain and spruce forests to evaporation requirements in Moravia in different yearsOriginal Paper

J. For. Sci., 2002, 48(7):320-327 | DOI: 10.17221/11891-JFS
Energy exchange above the floodplain forest and spruce monoculture ecosystems was measured in Moravia in 1988 and 1989. The results showed that the floodplain forest ecosystem with better access to groundwater than the spruce monoculture evaporated more rapidly. A higher flux of energy was recorded daily in latent heat (65% of net radiation) above the floodplain forest canopy, in contrast with the spruce plantation where it reached 17% only. The estimation of the floodplain forest actual evapotranspiration during the first half of June reached its maximum 0.17 g/m2/s, i.e. 0.6 mm/h. During the same...
Jananese flowering cherriesReview

The Japanese sato-zakura, literally "village cherries", represent perhaps the most popular subject of dendrology and ornamental horticulture. The authors rose to the occasion to write an extraordinary account of Japanese cherries and shed more light on a still confused group of these aristocratic flowering trees. Kuitert teaches at the Kyoto University of Art and Design while Peterse is a dedicated plant breeder and researcher of the Japanese flowering cherries. Rarely do professors have the time, or take the time, needed to solely write such a thoroughly prepared text. Both Dutchmen paid attention to detail, and the result is a well-written,...
