Comportamento Germinativo De Sementes De Eucalipto Em Duas Temperaturas Com O Uso De Sais Inorgânicos

Abstract: RESUMOO nitrato de cálcio e o nitrato de potássio podem ser utilizados no tratamento de sementes para favorecer rotas metabólicas que contribua no processo germinativo. O objetivo desse estudo foi avaliar o efeito de sais inorgânicos (nitrato de potássio e cálcio), em dois experimentos, um em condições normais de temperatura e outro em temperatura sub-ótima durante a germinação, no potencial fisiológico de sementes de Eucalyptus grandis. Os experimentos utilizaram temperaturas controladas, sendo o primeiro a 2… Show more

“…These cations can imbibe water fast and change the water potential of the seeds. Calcium nitrate pretreatment removed dormancy and enhanced germination in Brachiaria seeds (Silva et al, 2017). The priming of tomato seeds with CaCl 2 and KNO 3 solution was efficient to improve the seedling growth under salinity conditions (Ebrahimi et al, 2014).…”

“…In eggplant seeds, the osmopriming with potassium nitrate solution improved the germination rate when exposed to low temperatures (Nascimento & Lima, 2008). The calcium nitrate solution can also be used in seed pretreatment to improve the germination process and act to overcome dormancy in some seeds (Silva et al, 2017). For example, in Brachiaria seeds, the dormancy is related to several factors, especially physical properties, and the priming with calcium nitrate resulted in higher tolerance of Brachiaria brizantha seeds to high humidity and high-temperature stress (Batista et al, 2016), thus being efficient in overcoming dormancy.…”
