Abstract:

The seed of peach fruits develop the capacity to produce ethylene with a lag phase of about 1 h after excision. The site of ethylene synthesis is in the seed coat and rates as high as 6,000 μl kg(-1) h(-1) were recorded. Ethylene production was reduced to less than 1% of the control by 10 μg/ml cycloheximide. Although the tissue had only a small methionine pool, supplying the seed with exogenous methionine did not influence ethylene production at any stage of seed development. Label from [U-(14)C]methionine was readily incorporated into ethylene.

Fruit Development, Structure, and Function

Fruit Development, Structure, and Function

Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Seed Structure and Early Development of the Sporophyte

Seed Structure and Early Development of the Sporophyte

Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.
