Assessing the Potential Oleoresin Yields of Slash Pine Progenies at Juvenile Ages

Abstract

The potential oleoresin yields of slash pine progenies can be assessed at juvenile ages, 7 to 8 years earlier than with previous methods. Seeds are sown in peat pots, outplanted shortly after germination at a spacing of 14 by 3 feet, and given intensive cultural treatment. At 26 years from seed, when the trees average about 9 feet tall, their potential yields are evaluated by a miniature chipping technique.
