Alternatives to Eucalyptus for Pole Production - NCT Worldview - Pietermaritzburg
been much speculation about Eucalyptus grandis being the best specie for pole
production. In recent years there have
been Eucalyptus crosses made that would appear to be better for poles than the straight
E. grandis, but pole treatment plants have been reluctant to take them.
There is now
conclusive proof that the E. grandis x E. urophylla (GXU) and E. grandis x E.
nitens (GXN) are suitable for pole production and in some cases even better.
by SAUPA have indicated that the CSIR (NCT) clones GxU 111 and GxU 082 have a
better retention than E. grandis. The
GXU clones can be planted on any E. grandis site and have the added advantages
in that they are tolerant to the Gall Wasp, disease, canopy quickly, coppice
very well and will give you up to 30% better volume.
colder areas there is the option of GxN clones, in particular GxN 018b, AND GxN010. These clones have acceptable retention levels
but are denser than E.grandis. The GxN
010 and GXN 018b both have moderate snow tolerance. GxN 010 has tolerant to the Gall Wasp.
recommend that all farmers begin planting alternatives to E. grandis. The GXU
and GXN clones are available in commercial quantities from Sunshine Seedlings
