ABSTRACTAll mature individuals of Aglaia aff. flavida (Meliaceae) were mapped in a 260 ha study area at the Crater Mountain Biological Research Station in Papua New Guinea. Sixty-four reproductively mature trees were found in an aggregated distribution with a mean inter-tree distance of 88.9 m. The sample consisted of 35 female and 29 male trees with a mean shortest distance between sexes of 232 m. Seed production and seed removal of 22 female trees was monitored throughout the 1992 fruiting season. Female trees with in 200 m of male trees generally produced large seeds crops (> 100 seeds) whereas trees farther than 200 m from the nearest male had small seed crops (< 100 seeds) regardless of female size (DBH). Most seeds (63.2%, n = 3312) produced in a sub-sample of 22 trees came from the five most fecund trees, which also produced 74.1% of the seeds that were removed by vertebrate dispersers. Where a minority of a population of rare tropical trees produce the majority of progeny, sustainable harvest practices would be most effective where highly fecund individuals are identified and conserved.

Leaf Sample

Copra yield in Papua New Guinea is estimated at 0.6 tonnes per hectare per year. Several factors may be responsible for this low productivity compared to other Asia Pacific countries. Amongst these, nutrient deficiency is an important limiting factor. In order to evaluate coconut nutrition status in PNG, leaf sample collection was undertaken by examining 23 sites around the country and from a nutrition trial carried out at the Stewart Research Station of the PNG Cocoa & Coconut Research Institute (PNG-CCRI) in the Madang Province. Results of leaf analysis revealed significant widespread nitrogen deficiencies at most of the sampled sites and geographic variations in potash deficiency. Chlorine deficiency varied with geographic sites and was closely related to the prevailing wind pattern. Preliminary results on nut-set and flowering in the trial at Stewart Research Station revealed a positive response to nitrogen and chlorine-based fertilizer applications. This suggests that appropriate fertilizer applications would be benefit future coconut production on this particular site.

Good Resistance

The resistance of coconut palms to violent winds was observed at the Saraoutou research station as cyclone Dani passed over the island of Santo in Vanuatu in January 1999. Mortality caused by felling or uprooting was recorded on 13 Dwarf varieties, 10 Tall varieties and 28 Dwarf x Tall hybrids. The Dwarf palms were generally more susceptible than the Tall palms and hybrids, but substantial differences were also found between varieties in the same group. At 15 years old, the Tacunan Green Dwarf originating from the Philippines proved to be the most resistant Dwarf with 0% of felled palms compared to 100% of felled palms for the most susceptible, the Malayan Yellow Dwarf. Of the Tall palms, the Vanuatu Tall proved to be the most resistant with 2% of felled palms. The varieties originating from the South Pacific or the Philippines also displayed good resistance compared to varieties from Papua New Guinea. Of the hybrids, the Malayan Red Dwarf x Rennell Tall displayed the least resistance. The effect of different factors (morphological characteristics, age) on susceptibility to violent winds is discussed.
