Fruits may also be classified into a number of structural types. The individual seed-bearing structures of the flower called carpels constitute the gynoecium. The seed-containing cavity of a carpel is called the ovary, and its wall develops into the pericarp of the fruit. The edible fleshy part of a fruit most commonly develops from the ovary wall, but it may be also derived from the enlarged tip of stem from which floral organs arise, and sometimes leaf-like structures protecting the flowers may also become fleshy, e.g., in pineapple. 

The dynamics of AA production and utilization as well as the metabolic drifts of nucleic acids, proteins and other cell constituents have been studied in the shoot apex and differentiating floral organs of a number of species under different photoperlodlc and vernalization treatments and based upon these findings the ascorbic acid - nucleic acid -protein metabolism concept of growth and development was advanced (Chinoy, 1962) and subsequently elaborated (Chinoy and Mansurl, 1966 Chinoy, 1969). A brief resume of this concept Is reproduced here. 

As far as biodiversity of domestic floral species is concerned, research results concentrate on measuring the parameters crop rotation diversity, number of cultivated crops and grassland composition. Hausheer et al. (1998), evaluated crop rotations on 110 organic, integrated and conventional farms in a Swiss pilot farm project and determined the following situations on organic farms.
