The fitness of self-progeny individuals is inferior to that their outcrossed counterparts, resulting in a reduction plant population’s ability survive and reproduce. To prevent self‐fertilization, angiosperms with hermaphrodite flowers may exploit variety mechanisms, including synchronous dichogamy self-incompatibility. Synchronous involves two flowering morphs, strict within-morph synchronizat...

Summary The genus Ziziphus (Rhamnaceae) is revised for Borneo. 13 species are recognised using morphological evidence, including three new endemic species: cuspidata , Z. domatiata and puberula . Borneo therefore the island with greatest known diversity of species. area surrounding Mount Kinabalu particularly diverse, nine occurring in Ranau. Two varieties borneensis also described here, var. r...

objective: herbal medicine and medical plants such as ziziphus jujuba are widely used in the treatment of diseases such as diabetes mellitus. we investigated the effects of ethanol extracts of ziziphus jujuba fruit on serum glucose, triglycerides, ldl-cholesterol, hdl-cholesterol, cholesterol and activities of aminotransferase enzymes in streptozocin-induced diabetic adult male rats. materials ...

Increasing demand for more jujube (Ziziphus jujube Mill.) production requires understanding the specific fertilization needs of jujube trees. This study was conducted to compare fruit yields, phenolic profiles and antioxidant activity of jujube in response to different fertilizers. Application of organic fertilizer appeared to enhance the phenolics and antioxidant activity accumulation of jujub...

The aim of present study was to compare the effects of ultrasound-assisted and microwave-assisted extraction with solvent extraction method on antioxidant activities of jujube (Ziziphus mauritiana Lam.) leaf extracts in stability of sunflower oil during deep frying. The antioxidant activities of the extracts were evaluated by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH˙) radical scavenging and β...
