植物的复果植物的复果其实是由许多小果实聚集在一起而形成的果实.例如常见的菠萝就是一种复果.在菠萝和松球这些复果上可以观察到明显的斐波那契数列.在复果的表面以螺旋线的形式排列着一个个小果实.这种螺旋线,有的是左旋,有的是右旋.螺旋线的数目,在松球上看到的有5条、8条或13条,在菠萝上看到的有8条、13条等,这些条数都是斐波那契数. Complex plants of plants The complex of plants is actually a fruit formed by the aggregation of many small fruits, such as the common pineapple is a complex fruit, obvious Fibonacci can be observed on the fruits of pineapple and pine cone Number of rows in the complex fruit surface in the form of a spiral arrangement of a small fruit .This spiral, some of the left-hand, some right-handed. The number of spirals, seen on the loose ball 5, 8 or 13, 8, 13, etc. on the pineapple, all of which are Fibonacci numbers.
