| 41. | The larvae feed on dead sapwood, boring into dead trees and living in tunnels under the bark.
|
| 42. | The wood of " M . pomifera " is bright orange-yellow with paler yellow sapwood.
|
| 43. | The sapwood ( not often used ) is a creamy yellow, with a sharp boundary with the heartwood.
|
| 44. | The bark that is left overtop of the diamond changes quite markedly from the bark over the living sapwood.
|
| 45. | The sapwood is white to cream in color again depending on the species, but also on the location.
|
| 46. | Resin in the sapwood, however, is less at the base of the tree and increases with height.
|
| 47. | The more leaves a tree bears and the more vigorous its growth, the larger the volume of sapwood required.
|
| 48. | Timber : The sapwood is yellow; the heartwood light brown to dark red, straight grained and reasonably durable.
|
| 49. | This makes most efficient use of their properties as heartwood is best in compression whilst sapwood is superior in tension.
|
| 50. | In other desirable woods such as Osage orange and mulberry the sapwood is almost useless and is normally removed entirely.
