After reading this article you will learn about: 1. Methods of Dispersal of Fruits and Seeds 2. Dehiscence of Fruits. Methods of Dispersal of Fruits and Seeds: Dispersal by Wind: Either the whole fruit or the individual seeds may be suited to dispersal by wind. Seeds that are thus disseminated are characteristically light. The means of adaptation to wind dispersal [...]
The following three points will highlight the three main types of seed germination. The three main types are: (1) Hypogeal Germination (2) Epigeal Germination and (3) Vivipary (Viviparous Germination). Type # 1. Hypogeal Germination: In this kind of germination, the cotyledons do not come out of the soil surface. In such seeds the epicotyl (i.e., part of embryonic axis between [...]
In this article, we propose to discuss the types of seed dormancy and its role in plants life. The types are: (1) Immature Embryo (2) After-Ripening (3) Impermeability of Seed Coats (4) Tough Seed Coats (5) Inhibitors and (6) Excessive Salts. Seed dormancy or rest is the internal or innate inhibition of germination of otherwise normal or viable seed even [...]
