The physiological basis for genetic improvement of oil palm in Malaysia

摘要

Yield of Deliduraoil palms after four generations of selection was 60 greater than that of the unselected base population. Total above-ground dry matter production was increased by selection, apparently through better utilisation of solar radiation. The dry matter requirement for vegetative growth was unchanged, so a greater surplus remained for fruit production in the selected palms. Crossing theduraandpisiferato give the thin-shelledtenerafruit type improved partitioning of dry matter within the fruit, giving a 30 increase in oil yield at the expense of shell, without changing total dry matter production.
