Condicionamento osmótico de sementes de cubiu

Cubiu is a native Amazon plant that has attracted attention for its nutritional and pharmaceutical industries. The goal this paper was to evaluate the effect of priming on germination and seedling emergence from of three varieties of cubiu seeds: Santa Luzia, Thais and Musquet, using five priming conditions: water for 12 and 24 h, solutions of PEG 6000 and 0.35 Mol KNO3 for 24 and 48 h at 25 degrees C. Unprimed seeds were considered as control. After priming, seeds conditioned or not, were evaluated by means of tests: germination, speed of germination, seedling emergence and speed of emergence. The variety Thais had the best physiological quality, and priming in KNO3 which provided greater effects on germination and seed vigor cubiu.
