Fructification

In nature, the wild hop is usually shadowed during its growing period by bushes and trees, and it is only those aboveground parts which are intensively illuminated which pass into fructification period.

Lucuma salicifolia (canistal) and Micropholis mexicana (wild apricot) are the most infested fruit species. They have a very short fructification period.

Studying the duration of the flowering-fructification period among interspecific first-generation back-cross progenies of African species showed that this trait is positively correlated (r=0.78) with 100-seed weight and caffeine content.

The fructification is liable to become very convex in age.

The essence of the fructification consists in the flower and the fruit.

Postheterotopic transformations played a great role in the evolution of fructifications. The formation of specialized seed-like sporophylls in the Lepidocarpaceae, of strobilar fructifications in the Noeggerathiales, of various capsules and other seed-bearing organs of many gymnosperms belong here.
