Eucalyptus pellita Coppice vs. Seedlings as a Re-Establishment Method in South Sumatra, Indonesia
Eucalyptus pellita growth coppice regeneration coppice reduction fertiliser application
2023/12/4
Eucalyptus pellita can be regenerated through coppice. We report on the first known study of full-rotation productivity of E. pellita coppice and seedling re-establishment methods. We conducted this s...
Evaluation of O3 Effects on Cumulative Photosynthetic CO2 Uptake in Seedlings of Four Japanese Deciduous Broad-Leaved Forest Tree Species Based on Stomatal O3 Uptake
Japanese deciduous broad-leaved trees net photosynthetic rate net primary production stomatal
2024/3/8
The current level of tropospheric ozone (O3) is expected to reduce the net primary production of forest trees. Here, we evaluated the negative effects of O3 on the photosynthetic CO2 uptake of Japanes...
Physiological responses of seedlings of different Quercus castaneifolia C.A.Mey.provenances to heterogeneous light environments
peroxidase quantitative activity Hyrcanian forest chlorophyll content
2016/11/11
In this study, five biochemical traits obtained for seedlings of five different provenances of Quercus castaneifolia C.A. Meyer were used to evaluate the available light environment using instantaneou...
Effects of different irradiance levels on peroxidase activities in Quercus castaneifolia C.A.Mey.seedlings from different provenances
Hyrcanian vegetation zone abiotic stress polyacrylamide gel electrophoresis
2016/8/2
To understand the function of peroxidase (POD) in relation to a light gradient, changes in POD activity were studied in five different provenances of chestnut oak seedlings. An experiment was conducte...
Root rot and damping-off of Aleppo pine seedlings caused by Pythium spp. in Algerian forest nurseries
pathogenicity oomycetes Pinus halepensis Pythium ultimum Pythium heterothallicum seedling emergence
2016/8/2
Aleppo pine (Pinus halepensis Miller) is a common forest tree in the Mediterranean Region. Production of Aleppo pine seedlings is hindered by damping off and root rot diseases in cooler conditions of ...
Drought and aluminium as stress factors in Norway spruce (Picea abies) seedlings
drought aluminium proline water potential photosynthesis chlorophyll fluorescence
2015/3/27
Effects of drought, Al and their possible interaction on physiological characteristics were studied in four-years-old Norway spruce seedlings in a pot experiment. Drought stress was imposed by withhol...
Growth and physiological state of beech seedlings grown in a nursery in different light conditions
beech chlorophyll fluorescence Fagus sylvatica light conditions morphology seedlings
2015/3/19
Seedlings of European beech of two populations (from the 4th and 7th forest altitudinal zone) were grown in a shaded and unshaded plastic greenhouse. The objective was to compare seedling growth and t...
Production of Norway spruce (Picea abies [L.] Karst.) seedlings on substrate mixes using growth stimulants
Norway spruce seedlings substrates and their mixes biostimulant treatment
2015/2/6
We evaluated the growth of Norway spruce (Picea abies [L.] Karst.) seedlings on peat and bark substrates, on their mixes and on their mixes with agroperlite. We examined the basic quantitative traits ...
