Modeling Analysis on Germination and Seedling Growth Using Ultrasound Seed Pretreatment in Switchgrass
Switchgrass is a perennial C4 plant with great potential as a bioenergy source and, thus, a high demand for establishment from seed. This research investigated the effects of ultrasound treatment on germination and seedling growth in switchgrass. Using an orthogonal matrix design, conditions for the ultrasound pretreatment in switchgrass seed, including sonication time (factor A), sonication te...
متن کاملSeed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
متن کاملSeed dormancy and germination.
Seed dormancy and germination are complex adaptive traits of higher plants that are influenced by a large number of genes and environmental factors. Studies of genetics and physiology have shown the important roles of the plant hormones abscisic acid and gibberellin in the regulation of dormancy and germination. More recently, the use of quantitative genetics and mutant approaches has allowed t...
متن کاملSeed Germination and Dormancy.
Seeds are a vital component of the world’s diet. Cereal grains alone, which comprise -90% of all cultivated seeds, contribute up to half of the global per capita energy intake. Not surprisingly then, seed biology is one of the most extensively researched areas in plant physiology. Even in relation to the topics reviewed here, a casual perusal of the Agricola database reveals that well over 5000...
متن کاملCultivated Palm Seed Germination
The propagation of palms for agricultural and ornamental purposes is accomplished typically by seeds. The few exceptions are certain cultivars of Phoenix dactylifera and some ornamental palms such as Rhapis spp., which propagate by vegetative (division) and tissue culture. Because of slow, irregular germination in most species, seed propagation may be a challenge. New palm species are being int...
