-Introduction. Most commercial almonds are self-incompatible and growing these cultivars would increase orchard management costs. Self-compatible almond cultivar cultivation seems to be the solution to increase the yield and reduce the production costs. Materials and methods. In this study, the self-compatible almond cultivar Supernova was used as a seed parent and hand pollinated by the pollen of 'Shahrood 21', 'Shahrood 12', 'Fra Giulio Grande', '4-10', '11-5', and 'Supernova' itself. Also, two pollination methods were used, using 'Supernova' non-emasculated vs. emasculated flowers. Pollen tube growth of these pollinizers was studied by fluorescent microscopy at different times from flower samples harvested at 24, 48, 72, 96 and 120 h after hand pollination. The composition of fatty acids and the main characteristics of the fruit in the seed parent 'Supernova' were recorded after fruit harvest. Results and discussion. Although all pollens of the used pollinizers were compatible on 'Supernova' and had satisfied fruit set, significant differences were observed among pollinizers in stages 2 and 3. The highest fruit set was achieved when 'Shahrood 21' pollen was used, while the lowest fruit setting was recorded in 'Supernova' by self-pollination. Microscopic observation at 120 h after pollination revealed that pollen tubes of all pollinizers reached the ovary of 'Supernova'. In this study, fatty acid content was varied with oleic acid between 70.11 to 77.76%, linoleic acid from 4.0% to 5.5%, palmitic acid from 6.17 to 6.73%, stearic acid from 1.50 to 1.91%, palmitoleic acid from 0.40% to 0.47%, arachidic acid from 0.1 to 0.4%, gadoleic acid from 0.05 % to 0.06% and total oil content was between 50.25 to 51.59%. Conclusion. This experiment revealed that different pollen sources had a significant effect on fruit setting, but not in the oil content and fatty acid composition of the seed parent kernels.Keywords: Iran / almond / Prunus dulcis / pollen germination / sexual compatibility / S f allele / fruit quality / nutritional value Résumé -Effet d'une pollinisation complémentaire par différents pollinisateurs sur la mise à fruit et les caractéristiques physico-chimiques des amandes de l'amandier auto-compatible 'Supernova'.

En outre, deux méthodes de pollinisation ont été utilisées selon que les fleurs de « Supernova » étaient émasculées ou non.

“…Allanblackia seeds are mainly obtained from collections of wild mature fruits that drop off the tree. The seeds contain about 72% white fat (Foma and Abdala, 1985) that remains solid at ambient temperatures and consists mostly of oleic and stearic acid (Eckey, 1954;Hilditch, 1958, cf http://www.fao.org/docrep/X5043E0d.htm). Oleic and stearic acids are reported to lower plasma cholesterol levels (Bonanome and Grundy, 1988).…”

Abstract:Allanblackia seeds contain about 72% white fat (mostly of oleic and stearic acid), with high medicinal and industrial value, but the plant has not been domesticated, so seeds are only gotten from the wild. The demand for seeds of the wild Allanblackia floribunda exceeds supply and efforts to domesticate the plant to increase seed availability have been unsuccessful due to long seed dormancy periods. Soaking scarified seeds from immature fruits in water or fluridone shortened dormancy to less than 3 months, but the effects of different soak durations on germination, dormancy and seedling vigor, are not fully understood. This study aimed to determine the effects of three soak durations (1, 6, and 12 h) in water or fluridone (10 µM or 30 µM) on seed germination and seedling growth. The study was a 3 x 3 factorial experiment arranged in a Completely Randomized Design, using scarified immature seeds. At 16 weeks after treatment, seedlings were transplanted into polypots filled with topsoil and assessed weekly for the effects of treatments on seedling growth (leaf number and plant height). The % germination increased as the duration of soak in water or 10 µM fluridone increased from 1 to 12 h. The tendency to obtain 75-100% germination was higher when seeds were soaked in 10 µM fluridone (i.e., for 6 or 12 h) as compared to soaking in water for up to 12 h. The shortest duration (72 d, i.e., approx. 2.5 months) to achieve >75% germination was when Allanblackia seeds were soaked for 6 h in 10 µM fluridone. Soaking the seeds for 12 h in 10 µM fluridone resulted in 100% germination in 3 months. At transplanting, seedlings from fluridone treated seeds were taller, and had more leaves than those from seeds soaked in water for 1 or 6 h, but the reverse was observed in seedlings from seeds soaked for 12 h in water. However, these effects diminished after 2 weeks, when the seedlings have become established. This study has shown a promising method for achieving rapid and efficient germination of Allanblackia seeds with no noticeable adverse effects on seedling establishment.

“…Mature A. floribunda trees reach 30 m in height, 80 cm girth with bole straight and horizontal branches (Vivien and Faure 1996). Tallow tree is valued for its seeds, which are rich in hard fat (67-73%, Foma and Abdala 1985). This fat consists mostly of stearic and oleic acids (Hilditch et al 1940), which are reported to lower plasma cholesterol levels (Bonanome and Grundy 1988), thereby reducing the risks of heart attacks.…”

Founder group size is of prime importance in tree breeding programs. We determined whether sampling 20-plus trees for breeding in Allanblackia floribunda, a tropical forest tree species that has been recently enrolled in tree improvement program for fruit and seed production, would affect neutral genetic diversity and inbreeding level in both breeding and production populations. Using eight informative microsatellite loci, we: (a) assessed the nuclear genetic diversity of ten natural populations, and of the breeding population in the humid forest zone of Cameroon; (b) investigated temporal effective-size fluctuations in A. floribunda natural populations, with a view to identifying the role of past demographic events in the genetic structure of the studied species; and (c) tested the hypothesis that genetic diversity in a founder group of 20 individuals is not different from that existing in the wild. The eight loci were variable. High levels of genetic diversity (A=4.96; H E =0.59) and moderate differentiation (R ST =0.061) were found within and among populations in wild stands. High genetic distances existed between populations averagechorddistance ¼ 0:2769 AE 0:00554 ð Þ . Eight of the ten surveyed populations showed signs of deviation from mutation-drift equilibrium, suggesting Pleistocene population bottlenecks and fluctuations in effective population size. Mantel tests did not reveal any relationships between genetic and geographic distances. A neighbor-joining dendrogram showed a population structure that could be explained by historical factors. The hypothesis tested has been accepted. However, a slight increase in inbreeding was observed in the breeding population.
