Increasing pitch content of Pine by herbicide treatment

, : Increasing pitch content of Pine by herbicide treatment. Paperi ja Puu 57(9): 597-599

In Finland, treatment of exposed cambium with solutions (0.1, 1 or 10%) of paraquat or diquat induced resinosis to a height of 8 m above the treated area in Pinus sylvestris Treatment with herbicides increased the contents of acetone/petroleum-ether extractives by 5 to 20 times and the increases were mainly in rosin acids.

Hepatitis B virus core protein self-assembles into icosahedral, highly immunogenic capsid-like particles (CLPs) that can serve as molecular platforms for heterologous proteins. Insertion into the centrally located c/e1 epitope leads to surface dis...

Dispersal of avian ectoparasites can occur through either vertical transmission from adult birds to their offspring in the nest or through horizontal transmission between adult birds or through phoresy. In this study, we investigated the importanc...
