Tree Campus: Thundercloud Flowering Plum

Tree Campus SCC is a multi-year and interdisciplinary college initiative to document, map, and celebrate the incredible diversity of trees planted on the campus. With over 200 species, Shoreline Community College is an arboreal paradise that deserves to b


Thundercloud Flowering Plum

Prunus cerasifera 'Thundercloud' (ROSACEAE)



S.E. Europe, W. Asia



"Arbuscular mycorrhizal colonization [of Prunus cerasifera] increased root, stem and leaf weights, leaf area, root length and specific leaf area, and it decreased root length/leaf area ratio, root/shoot weight ratio and specific root length." [1]


Equity: Cultural and Historical Significance

"The fruits of the Myrobalan plum are rich in color-stable anthocyanins and contain an abundance of organic acids, pectin, mineral elements, and all essential amino acids. Once upon a time, the Myrobalan plum was one of the most popular fruits among the local residents of Huocheng because of the above-mentioned characteristics. Recently, the number of wild Myrobalan plum trees is reducing sharply because of reclamation, overstocking, and natural disaster." [2]



"Tree gum exudates are usually produced by the trunk, branches, and fruits, as a self-protection method in response to the injury or microbial invasion. Previous studies on the chemical structure of many plant gums showed that the tree gum exudates are mainly composed of hetero polysaccharides with complex structures and various monosaccharides. The wide industrial applications of tree gum are due to its water-retention capacity to produce gels and its ability to enhance the stability of emulsions. For example, the gum arabic has been used in food industry as natural stabilizer or emulsifiers. Besides, cashew gum has various applications in the agro-food, paper, cosmetic and pharmaceutical industries.

Recently, tree gum has been reported to be used as encapsulant and emulsifier in food industry, and as potential alternative to replace gum arabic in many fields of applications. The species of genus Prunus produce copious gum exudates, among which peach (such as P. persica) gum is the most studied. The studies on peach gum revealed that its main monosaccharide compositions were arabinose and galactose, and it also contained small amount of mannose, xylose, rhamnose and uronic acid... The Prunus cerasifera tree gum... is a mucosity liquid with high clarity or with a light yellow color.

Polysaccharide based materials, especially natural polysaccharide as a potential substitute for non-degradable materials, have received increasing attention owing to their biodegradable, easily available, low cost, nontoxic and biocompatible characteristics...

The copolymer synthesized from natural polysaccharides, which shows excellent performance in thermal stability and swelling capacity, can therefore be used as a precursor for preparation of a possibly large-scale advanced materials, and can be combined with other functional materials like metals, ceramics and nanocarbons for various applications including drug delivery, nutrition carrier, absorbent resin, polymer nanocomposties."
