Calophyllum inophyllum： recalcitrant or intermediate seed？

We studied seed storage behaviour of a multipurpose tree Calophyllum inophyllum (Clusiaseae). Seeds were collected at Roslyn bay (23°7′60″ S, 150°43′60″ E) Central Queensland. Seed drying and desiccation tolerance tests were carried out according to International Seed Testing Association (ISTA) rules. We found C. inophyllum seeds to be recalcitrant and vulnerable to chilling injury, hence, unsuited for cold storage. C. inophyllum seeds maintained their viability for an appreciable period (> 8 months) if stored in warmer environments.

Erratum to: DOI duplications

Eight articles in Journal of Forestry Research were published online but then became inaccessible when a technical error led to eight other articles being published with the same DOIs. They were then republished under new DOIs, as listed below: Article: Anthropogenic disturbances and status of forest and wildlife in the dry deciduous forests of Chhattisgarh state in India Original Article: Characterization of 14 anonymous nuclear loci in Pinus thunbergii and their cross-species transferability Original The publisher sincerely apologizes to all concerned and regrets the inconvenience caused.

Variations in bark thickness and sapwood density of Calophyllum inophyllum provenances in Australia and in Sri Lanka

Sapwood density and bark thickness of Calophyllum inophyllum L. (a multipurpose durable timber species) were studied in various locations in Northern Australia and in Sri Lanka. Measurements were taken non-destructively by using core sampling and bark gauge. From each provenance, 4–15 mature trees having girth at breast height over bark (GBHOB) at 100–150 cm were selected on the basis of the population size. Significant (p<0.05) hemispheric and provenance variations in bark thickness were found. Variations in the bark thickness are influenced by environmental variables. Variations in sapwood density were less pronounced compared to that of bark thickness. Variations in sapwood density are likely to be governed by genotypic variations.

Reproductive phenology of Calophyllum inophyllum in Yeppoon, Australia and Meegoda Western Province, Sri Lanka

Reproductive phenology of multiple use native plant Calophyllum inophyllum L. was studied in Yeppoon (23°7′60″ S, 150°43′60″ E), northern Australia (southern hemisphere) and in Meegoda (6°18′51″N, 80°31′3″), Sri Lanka (northern hemisphere). C. inophyllum trees in Yeppoon, Australia had relatively shorter flowering periods, shorter floral life spans, longer fruit life spans, smaller flowers and larger fruits compared to those in Meegoda, Sri Lanka. Although the number of flower buds/inflorescence was comparatively higher in Meegoda, C. inophyllum trees in both locations had similar mean number of mature fruits/cluster due to the higher floral abscission in C. inophyllum trees at Meegoda. Despite having a comparatively lower fruit yield (664 000 fruts·ha−·a−), C. inophyllum trees in Yeppoon had higher kernel weights (2 988.0±853.2 kg·ha−1·a−1) and oil yields (1 332.6±380.5 kg·ha−1·a−1) compared to those in Meegoda.
