“…The fruits of I. gabonensis were heavier, longer, wider and thicker than those of I. wombolu. Whilst the fruits of I. gabonensis weighed 125.08 g those of I. wombolu weighed 86.08 g. Previous studies undertaken by Atangana et al (2001) that did not differentiate between the two species showed that the mean weight of Irvingia fruits from two different villages were 99 g and 107g respectively. The mean weight of all fruits obtained in this present work was 105.58 g, and this would be comparable to the results of Atangana et al (2001) if I. gabonensis and I. wombolu were not treated separately.…”

“…Results in this work showed that fruits of Irvingia gabonensis were generally wider (62.66 mm) than they were long (60.85 mm) ( Table 1). On the other hand, the length (54.23 mm) and width (54.09 mm) of fruits of I. wombolu were about the same but Atangana et al (2001) showed that Irvingia fruits were consistently greater in length than in width. Inconsistent with the findings of Atangana et al (2001), an earlier report by Leakey and associates (2000) had shown that significant differences exist between trees with respect to fruit length and width.…”

Even though differences in Irvingia fruit weight have been reported amongst fruits obtained from different locations (Atangana et al, 2001;Leakey et al, 2000) they did not differ as a function of the different land uses (homegardens, cocoa farms, crop fields or fallows) (Atangana et al, 2001).…”

Irvingia (bush mango) species are economically important trees, but studies aimed at their prospect for domestication did not take into account the potential differences between members of the Genus. Hence fruit size, postharvest pathology and phytochemicals of I. gabonensis and I. wombolu were studied. Results showed that whilst the mean weight, length, width and thickness of fruits of I. gabonensis were 125.08g, 60.85mm, 62.66mm and 56.78mm, respectively, those obtained from I. wombolu were 86.08g, 54.23mm, 54.09mm and 50.97mm, respectively. Difference in brownish-black rot fruit disease between the two Irvingia species was not significant (P=0.05), but disease severity increased correspondingly with increase in storage days. Four genera of fungi (Aspergillus, Penicillium, Rhizopus and Mucor) were isolated from fruits of both Irvingia species, and I. wombolu was found to sustain a significantly lower fungal population (7.76E+07 cfu) than I. gabonensis (1.05E+08 cfu). High fungal population led to a correspondingly high severity of brownish-black rot disease. Fruits of both Irvingia species possessed all five phytochemicals (alkaloids, flavonoids, saponins, tannins and glucosides). However, whilst both species had the same amounts of flavonoids and glycosides, I. wombolu possessed relatively higher amounts of alkaloids, saponins and tannins than I. gabonensis. I. wombolu may be the preferred choice if domestication would be based on phytochemicals. In like manner, I. gabonensis may be the preferred choice for domestication if taste, weight and size of fruits were the parameters of interest.

Phenotypic variation in heartwood and essential-oil characters of Santalum austrocaledonicum was assessed across eleven populations on seven islands of Vanuatu. Trees differed significantly in their percentage heartwood cross-sectional area and this varied independently of stem diameter. The concentrations of the four major essential-oil constituents (alpha-santalol, beta-santalol, (Z)-beta-curcumen-12-ol, and cis-nuciferol) of alcohol-extracted heartwood exhibited at least tenfold and continuous tree-to-tree variation. Commercially important components alpha- and beta-santalol found in individual trees ranged from 0.8-47% and 0-24.1%, respectively, across all populations, and significant (P<0.05) differences for each were found between individual populations. The Erromango population was unique in that the mean concentrations of its monocyclic ((Z)-beta-curcumen-12-ol and cis-nuciferol) sesquiterpenes exceeded those of its bi- and tricyclic (alpha- and beta-santalol) sesquiterpenes. Heartwood colour varied between trees and spanned 65 colour categories, but no identifiable relationships were found between heartwood colour and alpha- and beta-santalol, although a weak relationship was evident between colour saturation and total oil concentration. These results indicate that the heartwood colour is not a reliable predictive trait for oil quality. The results of this study highlight the knowledge gaps in fundamental understanding of heartwood biology in Santalum genus. The intraspecific variation in heartwood cross-sectional area, oil concentration, and oil quality traits is of considerable importance to the domestication of sandalwood and present opportunities for the development of highly superior S. austrocaledonicum cultivars that conform to the industry's International Standards used for S. album.
