Recent fir hybridization research in the light of Czech-American cooperation
Abies hybridization breeding
2015/3/16
The project is based on control pollination of different fir species in the sense of interspecific hybridization. The aim of this procedure is a new bred material for specific needs of forestry and Ch...
Assimilation apparatus variability of beech transplants grown in variable light conditions of blue spruce shelter
beech transplants light nutrient content of leaves fluorescence of chlorophyll leaf area
2015/3/12
The paper valuates the differences in the selected characteristics of the assimilation apparatus of beech transplants growing in various light conditions of blue spruce small pole stage in the Jizersk...
Light distribution within forest edges in relation to forest regeneration
advanced planting forest edge light compensation point photon flux density
2015/2/6
Light conditions were measured along six transects from 35 m inside of a mixed Norway spruce/Scots pine forest to an adjoining clear-cut in NW-Austria. Photosynthetic photon flux density (PFD) was rec...
Effects of light exposure in freezing temperatures on winter damage to foliage of Norway spruce container seedlings in mid and late winter:Pilot experiments in an open field
cell damage frost irradiance needle colour Picea abies
2015/5/6
Norway spruce (Picea abies (L.) Karst.) is widely planted for reforestation in the boreal zone. It is sensitive to frost and high irradiance during the growing season, and also to winter damage, which...
Effects of grasses on sapling establishment and the role of transplanted saplings on the light environment of pastures: implications for tropical forest restoration
Degradation Light incidence Mexico Rain forest Recovery
2015/11/13
Saplings had high survival (49–88%) regardless of the presence of
grasses. In the presence of grasses, growth of surviving saplings either
increased or was not impacted, and in only one out of eight...
Reliability of Light-trapping Data to Represent the Annual Changing in the Number of Adult Emergences of Cypress Bark Moth Epinotia granitalis Butler (Lepidoptera: Totricidae) in Two Stands of Japanese Cedar Cryptomeria japonica (Taxodiaceae)
Epinotia granitalis feeding scar light trap number of emerged adult
2009/8/28
The cypress bark moth, Epinotia granitalis (Butler), is a serious insect pest of the Japanese cedar, Cryptomeria japonica. Light traps have been used for monitoring the number of moths in forests. How...
Influence of Parameters and Light Environment under the Canopy on the Fuel Moisture Estimation Model
fuels on forest floor litter moisture ratio solar radiation on forest floor
2009/8/28
Model parameterization was performed for estimation of the fuel moisture in adjacent plots with different tree species aiming at the mapping of forest fire hazard. One plot was covered with only decid...
Relationships between stand parameters and understorey light in boreal aspen stands
Relationships stand parameters understorey light boreal aspen stands
2009/1/8
Data from six aspen stands in northeastern British Columbia ranging in age from 12 to 40 years were used to examine relationships between understorey light levels and stand attributes (basal area, sta...
