Abstract: This paper introduced the concepts and main research contents of fruit ecology, summarized the related research advances, analyzed the shortcomings and gaps of the extant researches, and pointed out the future research perspectives. So far, some advances have been made in the correlativity between seed and fruit, fruit color and environment, fruit chemical components and environment, and fruit physical properties and geographic distribution pattern, and the coevolution between fruits and frugivores. However, following scientific issues need a further focus in the future: 1) the spatial differentiation patterns and their mechanisms of fruit physical traits such as mass spectrum and seed number per fruit, 2) the spatial variations and their mechanisms of fruit chemical components, and 3) the large scale geographical distribution patterns of fruit type composition modes and fruit type diversity and their environmental adaptation explanation, and the coevolution between fruit spread and frugivores.

Key words: high temperature, photosynthesis, photosynthetic enzyme, sub-high temperature, cucumber.
