“…These results might relate to the phloem mobility of potassium. Fruit calcium concentrations are often strongly negatively related to fruit mass whereas potassium concentrations are often more-weakly negatively related, or not related significantly, to fruit mass [93][94][95][96][97]. However, positive relationships between fruit potassium concentration and fruit mass have sometimes been detected in apple and avocado [94,95].…”

Tree nuts play an important role in healthy diets, but their economic value and nutritional quality may be affected by their size and paternity. We assessed relationships between nut size and kernel recovery, the incidence of whole kernels, fatty acid composition and mineral nutrient concentrations in three macadamia cultivars, "Daddow", "816" and "A4". We determined to what extent differences in nut size and quality were the result of different levels of cross-or self-paternity. Small nuts of all cultivars had lower kernel recovery than large nuts, and small nuts provided lower incidence of whole kernels in "Daddow" and "A4". Small kernels had a lower relative abundance of the saturated fatty acid, palmitic acid, in all cultivars and higher relative abundance of the unsaturated fatty acid, oleic acid, in "Daddow" and "A4". Small kernels had higher concentrations of many essential nutrients such as nitrogen and calcium, although potassium concentrations were lower in small kernels. Most nuts arose from cross-pollination. Therefore, nut size and kernel quality were not related to different levels of cross-and self-paternity. Identified cross-paternity was 88%, 78% and 90%, and identified self-paternity was 3%, 2% and 0%, for "Daddow", "816" and "A4", respectively. Small macadamia kernels are at least as nutritious as large macadamia kernels. High levels of cross-paternity confirmed that many macadamia cultivars are predominantly outcrossing. Macadamia growers may need to closely inter-plant cultivars and manage beehives to maximise cross-pollination.Plants 2020, 9, 228 2 of 14 also a valuable source of calcium, iron and zinc, which can be absorbed insufficiently during phases of high dietary demand such as infancy, childhood, adolescence, pregnancy and breastfeeding [16][17][18][19][20][21].The fatty acid composition and nutrient concentrations of tree-nut kernels can vary greatly among cultivars [9,[22][23][24][25][26][27][28]. Fatty acid composition and nutrient concentrations can also vary within almond or pistachio cultivars because of differences in the pollen parentage of individual kernels [22][23][24][25]29,30]. For example, self-pollinated kernels of some almond cultivars have lower oleic:linoleic acid ratios than cross-pollinated kernels [25,29]. In addition, self-pollinated kernels of some almond, chestnut and hazelnut cultivars are smaller than cross-pollinated kernels [22,[31][32][33]. Such effects of the paternal genetic background on the size or quality of the embryo are termed "xenia", and xenic effects are common in fruit and nut crops [34]. Therefore, maximising both yield and human-health benefits may depend upon ensuring high levels of cross-pollination in tree-nut orchards.Relationships between kernel size, nutritional composition, and cross-or self-paternity are poorly understood for some nuts, including the subtropical tree nut, macadamia (Macadamia integrifolia, M. tetraphylla and hybrids). Macadamia flowers are bee-pollinated and partially self-incompatible [35][36][37][38][39][40][41][42]...

Fruits of Strychnos spinosa Lam. hold considerable food value within rural communities. However, no study has reported the nutritional profile of S. spinosa morphotypes. Therefore, this study is aimed to determine nutritional variation among the morphotypes. Proximate composition was analyzed using association of official analytical chemists’ methods, and minerals with inductively coupled plasma atomic emission spectroscopy. The following were the ranges of proximate and nutrient content determined: moisture content (10.29–60.50%); fat (0.95–2.67%); crude protein (2.85–9.19%); ash (4.78–18.05%); carbohydrates (37.39–42.24%); acid detergent fibre (7.94–21.75%), neutral detergent fibre (16.46–42.55%); calcium (0.30–35 mg/100 g); potassium (810–2510 mg/100 g); phosphorus (9–69 mg/100 g); sodium (7–54 mg/100 g); magnesium (9–55 mg/100 g); copper (0.10–2.70 mg/100 g); iron (0.10–5.50 mg/100 g); manganese (0.30–2.43 mg/100 g) and zinc (0.10–0.80 mg/100 g). Calcium, phosphorus, magnesium, copper, iron, manganese, fat, acid detergent fibre, neutral detergent fibre, sodium, crude protein showed positive association with principal components. Biplot and dendrogram grouped morphotypes with high and low nutrient content independently. Carbohydrates, protein, calcium, potassium, copper, iron, manganese, and zinc content of morphotypes were higher than those in commercialized fruits. This species is promising for domestication and commercialization, and thereby contributes significantly towards food security.
