| Comments: | Recovery of yellow pine from grazing injury-top from specimen 18" in height. History: Lowest portion of stem is 3 1/2" stub of grazed 1927 leader. On this stub developed 3 leaf sheath buds which grew into 6" leader and 2 primary laterals 5" and 3 1/2", respectively, in 1928. Growth on 1928 laterals was not injured in 1929. The 1928 leader formed a leader and 2 primary laterals in 1929, all of which were grazed to short stubs without leaves and which died, as is always the case with stems grazed to below the point of needle growth. |
