Avocado seeds present high size variability. Larger seeds, such those of the &amp;#8216;Esther&amp;#8217; variety, are preferred when nurse seeds are used. Even though they are considered recalcitrant seeds, they are stored for propagation. The aim of this study was to evaluate the combined effect of three storage periods and three sizes of &amp;#8216;Esther&amp;#8217; avocado seeds on vigor, in terms of electrolyte leakage, and seedling length and diameter. The experiment was conducted using a completely randomized factorial design. The factors were time in storage (10, 30 and 100 d at 5 °C and 80% relative humidity) and seed size (small, medium and large). Electrolyte leakage was evaluated as a measure of seed vigor, growth and later development of the...

ABSTRACT:  Lippia rotundifolia is a native species of the Cerrado, endemic to the chain backbone and highly aromatic, whose essential oil has medicinal properties of high pharmacological value, but because it is a non-domesticated species, little is known about its spread. Due to its importance, the objective was to evaluate the effect of the osmotic conditioning on the physical and physiological quality of seeds. The experimental design was completely randomized with four replications of 100 seeds, being treatments consisted of two kinds of seeds (with and without tegument) subjected to ten days of immersion in water (0, 2, 4, 6, 12, 24, 48, 72, 96 and 120 hours). After each period, the seeds were submitted to the electrical conductivity test and...
