葡萄和提子如何区分

      葡萄和提子都是我们常吃的水果，二者外形相似，那它们是同一种水果吗？如何分辨它们 呢 ？

      葡萄和提子其实都是葡萄的果实，一般粒大、皮厚、汁少、优质、皮肉难分离、耐贮运的欧亚种葡萄被称为提子，而粒大、质软、汁多、易剥皮的果实被称为葡萄。

　　提子本来是传统粤语口语对葡萄的称呼，由于早年进口葡萄借用了粤语的称呼，所以提子在中国大部分地区的语境里仅指进口品种的葡萄。但在传统粤语的语境里，提子泛指所有种类的葡萄。一般情况下，在除粤语地区以外的其他地区，提子一般就指的是进口品种的葡萄。

　　葡萄有何营养？

　　葡萄富含葡萄糖及多种维生素，保护肝脏、减轻腹水和下肢浮肿的效果非常明显，还能提高血浆白蛋白浓度，降低转氨酶含量。

　　1. 抑制呼吸道炎症。葡萄中的白藜芦醇可作为抗氧化剂对抗由呼吸道病原菌引起的炎症。

　　2. 有益视力。葡萄籽中富含的低聚原花青素，可通过抑制细胞凋亡保护眼睛视力。

　　3. 防晒。葡萄中的黄酮类物质可以阻止破坏皮肤的酶产生，使皮肤细胞免受伤害，甚至能预防皮肤癌。

课程介绍：

About the course

The DPhil in Plant Sciences allows graduates to undertake both fundamental and applied research in topics across the breadth of plant science. You will gain a wide range of research skills as well as in-depth knowledge and expertise in your chosen field of research.

As a graduate student you will be embedded in the research groups of one or more members of academic staff who act as your supervisors and provide the bulk of the research guidance and training.

Alongside your research work, you will receive a number of training courses in your first and second years designed to develop skills you will need as a scientist and more general transferable skills. These include courses on critical analysis of the literature, scientific writing, presentation skills, as well as foundation courses in plant biodiversity, bioinformatics and statistics, if appropriate. All students undertake this training as a cohort so you will gain the benefit of working with your year group from across the department.

The department has a friendly and vibrant graduate community which provides a welcoming network to new students. The graduate student community offers a supportive environment, both social and scientific, allowing new graduates to develop into well-rounded and confident scientists. Graduates are a valued part of the department ’ s research community and their work is showcased annually at the departmental Graduate Symposium supported by prizes for the best graduate research seminar and poster.
