摘要

The genus Allanblackia consists of multipurpose, valuable non-timber forest tree species found in the rain forest zones of Africa. The seed oil of Allanblackia spp. has a high commercial value and demand for industrial purpose amounting to > 100,000 kg oil per year. Wild harvesting from Ghana, Nigeria and Tanzania cannot meet the market demand for Allanblackia oil, hence the need for domestication. A genebank of A. parviflora A. Chev. was established in Ghana in July 2007 for conservation of the genetic resources of the species and for future use in its domestication programme, using 406 seedlings derived from collections made from eight different populations in three different provenances in Ghana. Six years after establishment, the survival rate, growth parameters (height and diameter), reproductive biology (flowering and fruiting behaviour, flower colours and sex ratio of the trees) were assessed. The mean survival rate was 73.65 %. There was no significant difference in mean tree height (cm) (F = 1.017, df = 7, P > 0.05) and mean diameter at breast height (F = 1.683, df = 7, P > 0.05) among the populations. Mean tree height (F = 0.309, df = 2, P > 0.05) and mean diameter at breast height (F = 0.686, df = 2, P > 0.05) were also not significantly different among the provenances. There was a highly significant positive correlation between the volume of the tree and the number of fruits per tree (R = 0.483, P 0.0001), suggesting that fast growth could be an index for productivity and should be considered during selection.

Chev。种质库该公司于2007年7月在加纳成立，旨在保护该物种的遗传资源并在其驯化计划中将来使用，使用了来自加纳三种不同来源的8个不同种群的采集物的406株幼苗。建立后的六年，评估了成活率，生长参数（高度和直径），生殖生物学（开花和结果行为，花的颜色和树木的性别比）。平均存活率为73.65％。人群之间的平均树高（cm）（F = 1.017，df = 7，P> 0.05）和乳房高度的平均直径（F = 1.683，df = 7，P> 0.05）没有显着差异。各树种的平均树高（F = 0.309，df = 2，P> 0.05）和胸部高度的平均直径（F = 0.686，df = 2，P> 0.05）也没有显着差异。树的体积与每棵树的果实数量之间存在极显着的正相关（R = 0.483，P <0.0001），这表明快速生长可以作为生产力的指标，在​​选择时应予以考虑。
