What is it about?
The minimum chilling requirements of deciduous fruit trees have to be satisfied after entering natural dormancy, otherwise the quality and yield of fruit will be seriously affected. In this study, we measured the number of hours at between 0 and 7.2℃ required to break dormancy in 35 different kiwifruit genotypes.

Why is it important?
The results provide a basis for the introduction, rational distribution and promotion of cultivars suited to different locations, and lay the foundations for the breeding and selection of low-chill kiwifruit cultivars in south China.
Perspectives
I hope this article makes what people might think is a boring area like a experiment based on infinite repetition, kind of interesting and maybe even exciting. In this study, we found differences in chilling requirement among genotypes of kiwifruit. The chilling requirements were different from those of some other fruit tree species. These results provide a basis for the introduction, rational distribution and the promotion of cultivars suited to different locations, and lay the foundation for the breeding and selection of low-chill cultivars.
