Tolerância à dessecação e armazenamento de sementes de Myrcianthes pungens (O. Berg) D. Legrand (Myrtaceae)

Abstract

(Desiccation tolerance and storage of seeds of Myrcianthes pungens (O. Berg) D. Legrand (Myrtaceae)). Many barriers are found in the production of plantlets of species native to the tropics, largely due to the lack of knowledge about their seeds. Among these, the lack of technology to long store of recalcitrant seeds can also be a great risk to the loss of important plant diversity. In this work we analyzed the desiccation tolerance and the storage capacity of recalcitrant seeds of Myrcianthes pungens (O. Berg) D. Legrand. The results showed that M. pungens seeds are intolerant to desiccation up to 30% water, are better stored under low temperatures and, under high temperatures, have high rates of respiration and other oxidative processes.
