Unformatted text preview: Bean Germination Corn Germination Before we leave this subject, it is beneficial to mention two exceptions to normal seed development. (Methods of asexual propagation will be discussed with our plant modified structures section.) Apomyxis Seeds are produced without fertilization Example: Dandelion seeds Parthenocarpy Many fruits can be produced without seed development. This process, called parthenocarpy, may or may not require pollination. Certain hormones regulate the maturation of the ovary into the fruit portion of the plant. Either mutation, such as with the navel orange, or the use of hormone sprays on flowers, can result in the maturation of the ovary without seeds. Parthenocarpic plants must be propagated asexually. Navel oranges, for example, are propagated by grafting branches that produce navel oranges onto other orange tree stock....
