2009/8/27
To obtain the pine trees with high resistance to the pine wilt from susceptible species, the criteria for selective breeding should be made based on the inhibition factors of symptom development. Migr...
A weighted relative density model applied to loblolly pine（Pinus taeda L.）stands
relative density size-density Pinus taeda L loblolly pine
2009/3/3
We present a weighted, individual-tree relative density approach whose reference conditions have the same distribution of crown areas and species as a subject stand. An initial evaluation of the me...
Gravitropism of loblolly pine（Pinus taeda）radicles after chemical sterilization of seeds
Loblolly pine radicle geotropic growth microorganism H2O2
2009/3/3
Certain types of chemicals can affect the gravitropism of roots. In a laboratory study, intact loblolly pine (Pinus taeda L.) radicles (emerged from H2O2-treated seeds) exhibited positive gravitro...
