Seedling Emergence Peer Review Journals

The germination process begins when water is taken in (imbibed) by the seed. This initiates several biochemical events necessary for seedling development. For example, enzymes secreted from the aleuronic layer, break down carbohydrate in the endosperm converting it to simple sugars which nourish the embryo. All structural components of the grass seedling arise from the embryo. The endosperm provides a quick source of energy for the developmental process, whereas the cotyledon (rich in fats and oils) provides energy for later stages of development. In desert surroundings, plant survival is strongly limited by materialistic changes in water availability. Compared with mature plants, seedlings are more likely to suffer from water deficiency because their short roots are distributed only in dry hollow soil layers. Since seed germination determines when and where seedling growth begins, the success of seedling formation depends greatly on seed germination responses to the climate. For annual plants, which produce seed only once, seed germination responses to environmental conditions are necessary for recruitment. Deserts in China are characterized by a colder climate compared with many other deserts in the world —mean winter climate in Chinese deserts is below 0 °C, and winter is an unfavourable season for seed germination and plant growth.
