What is the structure of a grape flower?
The grape flower does not have conspicuous petals, instead, the petals are fused into a green structure termed the calyptra, but commonly referred to as the cap. The cap encloses the reproductive organs and other tissues within the flower. A flower consists of a single pistil (female organ) and five stamens, each tipped with an anther (male organ). The pistil is roughly conical in shape, with the base disproportionately larger than the top, and the tip (called the stigma) slightly flared. The broad base of the pistil is the ovary, and it consists of two internal compartments, each having two ovules containing an embryo sac with a single egg. The anthers produce many yellow pollen grains, which contain the sperm. Wild grapevines, rootstocks (and a few cultivated varieties such as St. Pepin) have either pistillate (female) or staminate male flowers — that is, the entire vine is either male or female. Vines with female, pistillate flowers need nearby vines with staminate or perfect flowers to produce fruit. The majority of commercial grapevine varieties have perfect flowers, that is, both male and female components.

Multiple pollen grains can germinate, each growing a pollen tube down the pistil to the ovary and entering an ovule, where a sperm unites with an egg to form an embryo. The successful union is termed fertilization, and the subsequent growth of berries is called “fruit set.”. The berry develops from the tissues of the pistil, primarily the ovary.
How many seeds are in a berry?
Because there are four ovules per flower, there is a maximum potential of four seeds per berry. Unfavorable environmental conditions during bloom such as cool, rainy weather can reduce fruit set (number of berries) and seeds per berry, thereby affecting berry size. Berry size is related to the number of seeds within the berry, and very few seeds leads to smaller berries. However, berry size can also be influenced by environmental conditions, management practices, and water management. Some immature berries may be retained by a cluster without completing their normal growth and development, a phenomenon known as “ coulure” or “hens and chicks” (Mullins et al., 1992).
