Heritable variation in tree growth and needle vegetation indices of slash pine (Pinus elliottii) using unmanned aerial vehicles (UAVs)
Pinus elliottii Heritable variation UAVs
2023/6/2
Vegetation indices (VIs) are mainly associated with plant yield, and yield-related physiological traits can assist in breeding selection. Tree breeding programs require a rapid assessment of a large n...
Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach
base-age invariant approach Chapman-Richards function global parameters tree-specific parameters iterative nested regression National Forest Inventory
2017/6/26
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
Production impacts of forest tree breeding on an example of Norway spruce
economic efficiency forest tree breeding growth Norway spruce production
2015/3/19
The present paper evaluates the height, diameter and stem volume of parental tree progenies. These Norway spruce progenies are compared with the control estimated from tables. The control was overperf...
Heavy metals uptake by the hybrid aspen and rowan-tree clones
phytoremediation heavy metals hybrid aspen
2015/3/5
Micropropagated plantlets derived from selected clones of the hybrid aspen (Populus tremula × Populus tremuloides) and the rowan-tree (Sorbus aucuparia L.) were used to determine the comparative study...
Variation of the tree form factor and taper in European larch of Polish provenances tested under conditions of the Beskid Sądecki mountain range (southern Poland)
genotype planting experiment stem profile
2015/3/5
The genetic variation in 20 provenances of European larch, growing under site conditions of the Beskid Sądecki mountain range (experimental area in Krynica), was investigated during a long-term s...
Conversion of substitute tree species stands and pure spruce stands in theOreMountains inSaxony– A Report
substitute tree species stands pure spruce stands species composition conversion Ore Mountains Mts. Germany
2015/2/6
The original natural forest ecosystems of the OreMountains(Norway spruce, silver fir, and beech forests) have been destroyed by overcropping since the 11th century. In the 19th century spruce afforest...
Genetic basis of pathogen community structure for foundation tree species in a common garden and in the wild
common garden and wild contrasts community genetics cottonwoods, density effects
2015/11/13
Genetic variation within and among foundation plant species is known to affect arthropod, plant and soil
microbial communities. We hypothesized that the same would be expected for pathogen communitie...
Discrimination of Sugi (Cryptomeria japonica D. Don) Plus-tree Clones Using SSR Marker Analysis
clone discrimination discrimination power SSR marker sugi plus tree
2009/8/28
Eight hundred and thirty-five sugi (Cryptomerica japonica D. Don) plus-tree clones from the Kanto Breeding Region were genotyped using three highly polymorphic SSR markers. With a mean observed hetero...
Influences of Mast Seeding on Tree Growth Dynamics of Fagus crenata and Fagus japonica in Central Honshu,Japan
Fagus crenata Fagus japonica mast seeding leaf litterfall basal area increment
2009/8/24
We investigated influences of mast seeding on tree growth, in relation to beech tree species Fagus crenata and F.japonica dynamics of leaf litterfall. The study objective was to clarify any relations ...

林木遗传连锁图谱构建研究进展与发展方向Research Progress in Forest Tree Genetic Linkage Map Construction and Its Future Prospects
遗传连锁图谱 QTL定位 表达序列标签多态性（ESTP） 比较作图
2008/1/16
摘要本文就目前国内外林木连锁遗传图谱领域的研究进展进行了综述，指出了该领域研究中存在的主要问题，即一方面是作图个体的数量有限，另一方面是采用的标记以随机标记为主，导致了建成的图谱以及利用图谱获得的数量性状基因位点（QTLs）信息具有杂交组合特异性，造成了QTLs的可信度和在林木遗传改良以及标记辅助选择中的实用性降低等现象。针对存在的问题，讨论了根据林木生物学特点选择合适遗传标记的意义，指出进行林木...
