ABSTRACT: Desiccation sensitivity is a condition present in seeds of several tree species of economic and ecological importance, which makes such seeds unable to tolerate drying and storage. Thus, studies that seek strategies to maintain the viability of such seeds after being subjected to drying are necessary. An alternative for this purpose is the use of priming in solutions of known osmotic potential. Solutions of polyethylene glycol (PEG), glycerol, as well as phytohormones such as abscisic acid (ABA) and salicylic acid (SA) are related to stress tolerance in seeds. The objective of this work was to study desiccation sensitive seeds of Inga vera, Eugenia uniflora and Tapirira guianensis, using solutions of PEG, SA, sucrose, glycerol and combinations of SA+PEG in an attempt of reducing seed desiccation sensitivity. The responses varied according to the species, but in general, successful results in maintaining the viability of the seeds after drying were obtained from the treatmen of seed with sucrose, glycerol and combinations of PEG and SA. Treatment of seeds with these compounds is promising in reducing the desiccation sensitivity of seeds of tree species. |
