Why do some fruits develop without seeds?

Seedless fruits are produced by parthenocarpy, in which the ovaries develop without fertilization. This is a normal occurrence in nature, found in bananas, seedless grapes, and some citrus fruits. Certain genetic mutations cause the fruit to form without the usual process of fertilization in plants. The fruit has fleshy edible parts, but it does not contain viable seeds. Commercial growers seek such varieties for their consumer appeal.

Parthenocarpy occurs through various biological mechanisms. Some plants produce parthenocarpically naturally, as in the case of wild bananas. Others show it only when men interfere through selective breeding. Hormonal treatment can induce parthenocarpy in other species, as seen in the case of the tomato. By these methods, fruits are produced without the need for pollination or fertilization.

Seedless fruits also offer benefits for consumers. There is no need to deal with seeds when eating them. They have a texture that is unevenly straight with no variation. Commercial growers also benefit from the higher demand in the marketplace. These kinds of fruits also tend to have longer shelf lives.

Seedless varieties may be grown successfully by gardeners. Select the cultivars best suited to the climatic zone. Supply plants with consistent moisture and nourishment. Use hormone sprays where desirable on seedless tomatoes. Remember that since these plants are seedless, they can only be propagated by vegetative methods, such as by cuttings.

Understanding the biology of seedless fruits enhances appreciation for contemporary agriculture. These fruits represent a capacity to modify the reproductive biology of plants. Fruits also offer nutrition and are convenient to eat. The specific varieties of fruit you choose support different cultivation practices and biological replacements.
