Abstract Genetic diversity in over-exploited and threatened species has important, but often neglected, implications for conservation. In South Africa, the bark of regionally endangered pepper-bark tree, Warburgia salutaris , is extensively harvested subsistence medicine. We developed 11 polymorphic microsatellite markers to examine genetic structure among 227 W. individuals sampled from across...

Tree root balls from nurseries are often too heavy for one or two people to lift and plant, but powerful machinery can be expensive for small landscaping organizations or the weekend home gardener. This thesis intends to document the market for such a device and describe why the current products don't meet the specific requirements of the groups listed. The progress of designing a new device is...

Phosphorus deficiency is a major limiting factor in horticultural production. One potential solution can be restoring soil phosphorus from mineral resources, such as solid phosphate sludge (SPS) generated treatment processes at mining sites agriculture. This study explores the possibility of using this nurseries to produce fruit and forest plants. We tested six mixtures SPS with sandy Maamora o...

Chilling of avocado fruit (Persea americana cv. Arad) in the orchard caused a dramatic induction of fruit ripening and a parallel increase in ethylene biosynthesis and receptor genes' expression during shelf life. In-orchard chilling stress stimulated ethylene and CO(2) production already in fruit attached to the tree, and these reduced thereafter during 20 degrees C storage. In non-chilled con...

Short growing season restricts production of standard-sized fruit trees in nurseries at cold regions. Enhancing plant growth by optimizing program of mineral nutrition may solve the problem. This study evaluated efficiency of fertilizers [urea, sulfur coated urea (SCU), or foliar applications of a NPK compound fertilizer] for optimizing the growth of seedling rootstocks and grafted young almond...

With sustainability at the heart of Fédération Internationale de Football Association (FIFA) World Cup 2022™, Qatar has set a track to achieve carbon neutrality, committing deliver first-ever neutral mega event in world. Achieving these goals require offsetting emissions through quality projects within and outside state. Tree nurseries with stress-tolerant variants play significant role cutting...

Growth-related characters, condition factor, and genetic differentiation were investigated for a single cohort of young-of-the-year (YOY) sole within and among nurseries with differing levels of heavy metals (Cd, Cu and Zn) contamination in the two Charentais Straits, Bay of Biscay, France. Analyses were performed when individuals recruited (May), then after a full summer spent in each nursery ...
