Abstract
Abstract: Several studies have successfully used polyethylene glycol (PEG) and/or abscisic acid (ABA) to reinduce desiccation tolerance in germinated seeds of orthodox species, improving our understanding of the mechanisms that underlie this trait. In this context, treatments with PEG and ABA were tested to assess their efficiency in reducing the sensitivity to desiccation and increasing the storage period of Magnolia ovata seeds. The drying of seeds to 10% water did not significantly affect germination, nor was germination impaired in seeds that were dried and treated with ABA. However, seeds treated with PEG had lower viability. After storage, ABA-treated seeds with as low as 5% water content (WC) had higher germination rates, the treatment with 100 µM ABA providing the greatest storage capacity. No changes were observed in the activity of catalase, peroxidase, or superoxide dismutase or in the abundance of total or heat-resistance proteins.
期刊介绍：
From 2017 the Journal of Seed Science (JSS) will circulate online version only.
Original scientific studies and communications, not yet published or submitted to another journal for publication and written in Portuguese or English, will be accepted for publication. For manuscripts submitted in English, the authors should provide an adequated version.
The SCIENTIFIC COMMUNICATION is a category of scientific manuscript which describes a technique, an equipment, new species or observations and surveys of limited results. It has the same scientific rigor as the “Scientific Articles” and the same value as a publication. The classification of a manuscript as a SCIENTIFIC COMMUNICATION is based on its content and scientific merit but it can be a preliminary study, simple and not definitive on a certain subject, with publication justified by its uniqueness and contribution to the area.
The Editorial Board of the JSS may invite leading authors of recognized reputation to compose specific Review Articles covering topics of their specialization that will convey to the scientific community the state-of-the-art knowledge related to the specific theme.
